Apache¶
The Apache plugin currently supports modern OSes based on Debian, Fedora, SUSE, Gentoo, CentOS and Darwin. This automates both obtaining and installing certificates on an Apache webserver. To specify this plugin on the command line, simply include --apache.
Webroot¶
If you’re running a local webserver for which you have the ability to modify the content being served, and you’d prefer not to stop the webserver during the certificate issuance process, you can use the webroot plugin to obtain a certificate by including certonlyand --webroot on the command line. In addition, you’ll need to specify --webroot-pathor -w with the top-level directory (“web root”) containing the files served by your webserver. For example, --webroot-path /var/www/html or --webroot-path/usr/share/nginx/html are two common webroot paths.
If you’re getting a certificate for many domains at once, the plugin needs to know where each domain’s files are served from, which could potentially be a separate directory for each domain. When requesting a certificate for multiple domains, each domain will use the most recently specified --webroot-path. So, for instance,
certbot certonly --webroot -w /var/www/example -d www.example.com -d example.com -w /var/www/other -d other.example.net -d another.other.example.net
would obtain a single certificate for all of those names, using the /var/www/examplewebroot directory for the first two, and /var/www/other for the second two.
The webroot plugin works by creating a temporary file for each of your requested domains in ${webroot-path}/.well-known/acme-challenge. Then the Let’s Encrypt validation server makes HTTP requests to validate that the DNS for each requested domain resolves to the server running certbot. An example request made to your web server would look like:
以下certbot -h all リスト
$ certbot -h all
usage:
certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...
Certbot can obtain and install HTTPS/TLS/SSL certificates. By default,
it will attempt to use a webserver both for obtaining and installing the
certificate. The most common SUBCOMMANDS and flags are:
obtain, install, and renew certificates:
(default) run Obtain & install a certificate in your current webserver
certonly Obtain or renew a certificate, but do not install it
renew Renew all previously obtained certificates that are near expiry
enhance Add security enhancements to your existing configuration
-d DOMAINS Comma-separated list of domains to obtain a certificate for
--apache Use the Apache plugin for authentication & installation
--standalone Run a standalone webserver for authentication
--nginx Use the Nginx plugin for authentication & installation
--webroot Place files in a server's webroot folder for authentication
--manual Obtain certificates interactively, or using shell script hooks
-n Run non-interactively
--test-cert Obtain a test certificate from a staging server
--dry-run Test "renew" or "certonly" without saving any certificates to disk
manage certificates:
certificates Display information about certificates you have from Certbot
revoke Revoke a certificate (supply --cert-name or --cert-path)
delete Delete a certificate (supply --cert-name)
reconfigure Update a certificate's configuration (supply --cert-name)
manage your account:
register Create an ACME account
unregister Deactivate an ACME account
update_account Update an ACME account
show_account Display account details
--agree-tos Agree to the ACME server's Subscriber Agreement
-m EMAIL Email address for important account notifications
optional arguments:
-h, --help show this help message and exit
-c CONFIG_FILE, --config CONFIG_FILE
path to config file (default: /etc/letsencrypt/cli.ini
and ~/.config/letsencrypt/cli.ini)
-v, --verbose This flag can be used multiple times to incrementally
increase the verbosity of output, e.g. -vvv. (default:
0)
--max-log-backups MAX_LOG_BACKUPS
Specifies the maximum number of backup logs that
should be kept by Certbot's built in log rotation.
Setting this flag to 0 disables log rotation entirely,
causing Certbot to always append to the same log file.
(default: 1000)
-n, --non-interactive, --noninteractive
Run without ever asking for user input. This may
require additional command line flags; the client will
try to explain which ones are required if it finds one
missing (default: False)
--force-interactive Force Certbot to be interactive even if it detects
it's not being run in a terminal. This flag cannot be
used with the renew subcommand. (default: False)
-d DOMAIN, --domains DOMAIN, --domain DOMAIN
Domain names to include. For multiple domains you can
use multiple -d flags or enter a comma separated list
of domains as a parameter. All domains will be
included as Subject Alternative Names on the
certificate. The first domain will be used as the
certificate name, unless otherwise specified or if you
already have a certificate with the same name. In the
case of a name conflict, a number like -0001 will be
appended to the certificate name. (default: Ask)
--eab-kid EAB_KID Key Identifier for External Account Binding (default:
None)
--eab-hmac-key EAB_HMAC_KEY
HMAC key for External Account Binding (default: None)
--cert-name CERTNAME Certificate name to apply. This name is used by
Certbot for housekeeping and in file paths; it doesn't
affect the content of the certificate itself. To see
certificate names, run 'certbot certificates'. When
creating a new certificate, specifies the new
certificate's name. (default: the first provided
domain or the name of an existing certificate on your
system for the same domains)
--dry-run Perform a test run of the client, obtaining test
(invalid) certificates but not saving them to disk.
This can currently only be used with the 'certonly'
and 'renew' subcommands. Note: Although --dry-run
tries to avoid making any persistent changes on a
system, it is not completely side-effect free: if used
with webserver authenticator plugins like apache and
nginx, it makes and then reverts temporary config
changes in order to obtain test certificates, and
reloads webservers to deploy and then roll back those
changes. It also calls --pre-hook and --post-hook
commands if they are defined because they may be
necessary to accurately simulate renewal. --deploy-
hook commands are not called. (default: False)
--debug-challenges After setting up challenges, wait for user input
before submitting to CA. When used in combination with
the `-v` option, the challenge URLs or FQDNs and their
expected return values are shown. (default: False)
--preferred-chain PREFERRED_CHAIN
Set the preferred certificate chain. If the CA offers
multiple certificate chains, prefer the chain whose
topmost certificate was issued from this Subject
Common Name. If no match, the default offered chain
will be used. (default: None)
--preferred-challenges PREF_CHALLS
A sorted, comma delimited list of the preferred
challenge to use during authorization with the most
preferred challenge listed first (Eg, "dns" or
"http,dns"). Not all plugins support all challenges.
See https://certbot.eff.org/docs/using.html#plugins
for details. ACME Challenges are versioned, but if you
pick "http" rather than "http-01", Certbot will select
the latest version automatically. (default: [])
--issuance-timeout ISSUANCE_TIMEOUT
This option specifies how long (in seconds) Certbot
will wait for the server to issue a certificate.
(default: 90)
--user-agent USER_AGENT
Set a custom user agent string for the client. User
agent strings allow the CA to collect high level
statistics about success rates by OS, plugin and use
case, and to know when to deprecate support for past
Python versions and flags. If you wish to hide this
information from the Let's Encrypt server, set this to
"". (default: CertbotACMEClient/2.5.0 (certbot; Ubuntu
22.04.2 LTS) Authenticator/XXX Installer/YYY
(SUBCOMMAND; flags: FLAGS) Py/3.8.10). The flags
encoded in the user agent are: --duplicate, --force-
renew, --allow-subset-of-names, -n, and whether any
hooks are set.
--user-agent-comment USER_AGENT_COMMENT
Add a comment to the default user agent string. May be
used when repackaging Certbot or calling it from
another tool to allow additional statistical data to
be collected. Ignored if --user-agent is set.
(Example: Foo-Wrapper/1.0) (default: None)
automation:
Flags for automating execution & other tweaks
--keep-until-expiring, --keep, --reinstall
If the requested certificate matches an existing
certificate, always keep the existing one until it is
due for renewal (for the 'run' subcommand this means
reinstall the existing certificate). (default: Ask)
--expand If an existing certificate is a strict subset of the
requested names, always expand and replace it with the
additional names. (default: Ask)
--version show program's version number and exit
--force-renewal, --renew-by-default
If a certificate already exists for the requested
domains, renew it now, regardless of whether it is
near expiry. (Often --keep-until-expiring is more
appropriate). Also implies --expand. (default: False)
--renew-with-new-domains
If a certificate already exists for the requested
certificate name but does not match the requested
domains, renew it now, regardless of whether it is
near expiry. (default: False)
--reuse-key When renewing, use the same private key as the
existing certificate. (default: False)
--no-reuse-key When renewing, do not use the same private key as the
existing certificate. Not reusing private keys is the
default behavior of Certbot. This option may be used
to unset --reuse-key on an existing certificate.
(default: False)
--new-key When renewing or replacing a certificate, generate a
new private key, even if --reuse-key is set on the
existing certificate. Combining --new-key and --reuse-
key will result in the private key being replaced and
then reused in future renewals. (default: False)
--allow-subset-of-names
When performing domain validation, do not consider it
a failure if authorizations can not be obtained for a
strict subset of the requested domains. This may be
useful for allowing renewals for multiple domains to
succeed even if some domains no longer point at this
system. This option cannot be used with --csr.
(default: False)
--agree-tos Agree to the ACME Subscriber Agreement (default: Ask)
--duplicate Allow making a certificate lineage that duplicates an
existing one (both can be renewed in parallel)
(default: False)
-q, --quiet Silence all output except errors. Useful for
automation via cron. Implies --non-interactive.
(default: False)
security:
Security parameters & server settings
--rsa-key-size N Size of the RSA key. (default: 2048)
--key-type {rsa,ecdsa}
Type of generated private key. Only *ONE* per
invocation can be provided at this time. (default:
ecdsa)
--elliptic-curve N The SECG elliptic curve name to use. Please see RFC
8446 for supported values. (default: secp256r1)
--must-staple Adds the OCSP Must-Staple extension to the
certificate. Autoconfigures OCSP Stapling for
supported setups (Apache version >= 2.3.3 ). (default:
False)
--redirect Automatically redirect all HTTP traffic to HTTPS for
the newly authenticated vhost. (default: redirect
enabled for install and run, disabled for enhance)
--no-redirect Do not automatically redirect all HTTP traffic to
HTTPS for the newly authenticated vhost. (default:
redirect enabled for install and run, disabled for
enhance)
--hsts Add the Strict-Transport-Security header to every HTTP
response. Forcing browser to always use SSL for the
domain. Defends against SSL Stripping. (default: None)
--uir Add the "Content-Security-Policy: upgrade-insecure-
requests" header to every HTTP response. Forcing the
browser to use https:// for every http:// resource.
(default: None)
--staple-ocsp Enables OCSP Stapling. A valid OCSP response is
stapled to the certificate that the server offers
during TLS. (default: None)
--strict-permissions Require that all configuration files are owned by the
current user; only needed if your config is somewhere
unsafe like /tmp/ (default: False)
--auto-hsts Gradually increasing max-age value for HTTP Strict
Transport Security security header (default: False)
testing:
The following flags are meant for testing and integration purposes only.
--run-deploy-hooks When performing a test run using `--dry-run` or
`reconfigure`, run any applicable deploy hooks. This
includes hooks set on the command line, saved in the
certificate's renewal configuration file, or present
in the renewal-hooks directory. To exclude directory
hooks, use --no-directory-hooks. The hook(s) will only
be run if the dry run succeeds, and will use the
current active certificate, not the temporary test
certificate acquired during the dry run. This flag is
recommended when modifying the deploy hook using
`reconfigure`. (default: False)
--test-cert, --staging
Use the staging server to obtain or revoke test
(invalid) certificates; equivalent to --server
https://acme-staging-v02.api.letsencrypt.org/directory
(default: False)
--debug Show tracebacks in case of errors (default: False)
--no-verify-ssl Disable verification of the ACME server's certificate.
The root certificates trusted by Certbot can be
overriden by setting the REQUESTS_CA_BUNDLE
environment variable. (default: False)
--http-01-port HTTP01_PORT
Port used in the http-01 challenge. This only affects
the port Certbot listens on. A conforming ACME server
will still attempt to connect on port 80. (default:
80)
--http-01-address HTTP01_ADDRESS
The address the server listens to during http-01
challenge. (default: )
--https-port HTTPS_PORT
Port used to serve HTTPS. This affects which port
Nginx will listen on after a LE certificate is
installed. (default: 443)
--break-my-certs Be willing to replace or renew valid certificates with
invalid (testing/staging) certificates (default:
False)
paths:
Flags for changing execution paths & servers
--cert-path CERT_PATH
Path to where certificate is saved (with certonly
--csr), installed from, or revoked (default: None)
--key-path KEY_PATH Path to private key for certificate installation or
revocation (if account key is missing) (default: None)
--fullchain-path FULLCHAIN_PATH
Accompanying path to a full certificate chain
(certificate plus chain). (default: None)
--chain-path CHAIN_PATH
Accompanying path to a certificate chain. (default:
None)
--config-dir CONFIG_DIR
Configuration directory. (default: /etc/letsencrypt)
--work-dir WORK_DIR Working directory. (default: /var/lib/letsencrypt)
--logs-dir LOGS_DIR Logs directory. (default: /var/log/letsencrypt)
--server SERVER ACME Directory Resource URI. (default:
https://acme-v02.api.letsencrypt.org/directory)
manage:
Various subcommands and flags are available for managing your
certificates:
certificates List certificates managed by Certbot
delete Clean up all files related to a certificate
renew Renew all certificates (or one specified with --cert-
name)
revoke Revoke a certificate specified with --cert-path or
--cert-name
reconfigure Update renewal configuration for a certificate
specified by --cert-name
run:
Options for obtaining & installing certificates
certonly:
Options for modifying how a certificate is obtained
--csr CSR Path to a Certificate Signing Request (CSR) in DER or
PEM format. Currently --csr only works with the
'certonly' subcommand. (default: None)
renew:
The 'renew' subcommand will attempt to renew any certificates previously
obtained if they are close to expiry, and print a summary of the results.
By default, 'renew' will reuse the plugins and options used to obtain or
most recently renew each certificate. You can test whether future renewals
will succeed with `--dry-run`. Individual certificates can be renewed with
the `--cert-name` option. Hooks are available to run commands before and
after renewal; see https://certbot.eff.org/docs/using.html#renewal for
more information on these.
--pre-hook PRE_HOOK Command to be run in a shell before obtaining any
certificates. Unless --disable-hook-validation is
used, the command’s first word must be the absolute
pathname of an executable or one found via the PATH
environment variable. Intended primarily for renewal,
where it can be used to temporarily shut down a
webserver that might conflict with the standalone
plugin. This will only be called if a certificate is
actually to be obtained/renewed. When renewing several
certificates that have identical pre-hooks, only the
first will be executed. (default: None)
--post-hook POST_HOOK
Command to be run in a shell after attempting to
obtain/renew certificates. Unless --disable-hook-
validation is used, the command’s first word must be
the absolute pathname of an executable or one found
via the PATH environment variable. Can be used to
deploy renewed certificates, or to restart any servers
that were stopped by --pre-hook. This is only run if
an attempt was made to obtain/renew a certificate. If
multiple renewed certificates have identical post-
hooks, only one will be run. (default: None)
--deploy-hook DEPLOY_HOOK
Command to be run in a shell once for each
successfully issued certificate. Unless --disable-
hook-validation is used, the command’s first word must
be the absolute pathname of an executable or one found
via the PATH environment variable. For this command,
the shell variable $RENEWED_LINEAGE will point to the
config live subdirectory (for example,
"/etc/letsencrypt/live/example.com") containing the
new certificates and keys; the shell variable
$RENEWED_DOMAINS will contain a space-delimited list
of renewed certificate domains (for example,
"example.com www.example.com") (default: None)
--disable-hook-validation
Ordinarily the commands specified for --pre-
hook/--post-hook/--deploy-hook will be checked for
validity, to see if the programs being run are in the
$PATH, so that mistakes can be caught early, even when
the hooks aren't being run just yet. The validation is
rather simplistic and fails if you use more advanced
shell constructs, so you can use this switch to
disable it. (default: False)
--no-directory-hooks Disable running executables found in Certbot's hook
directories during renewal. (default: False)
--disable-renew-updates
Disable automatic updates to your server configuration
that would otherwise be done by the selected installer
plugin, and triggered when the user executes "certbot
renew", regardless of if the certificate is renewed.
This setting does not apply to important TLS
configuration updates. (default: False)
--no-autorenew Disable auto renewal of certificates. (default: False)
certificates:
List certificates managed by Certbot
delete:
Options for deleting a certificate
revoke:
Options for revocation of certificates
--reason {unspecified,keycompromise,affiliationchanged,superseded,cessationofoperation}
Specify reason for revoking certificate. (default:
unspecified)
--delete-after-revoke
Delete certificates after revoking them, along with
all previous and later versions of those certificates.
(default: None)
--no-delete-after-revoke
Do not delete certificates after revoking them. This
option should be used with caution because the 'renew'
subcommand will attempt to renew undeleted revoked
certificates. (default: None)
register:
Options for account registration
--register-unsafely-without-email
Specifying this flag enables registering an account
with no email address. This is strongly discouraged,
because you will be unable to receive notice about
impending expiration or revocation of your
certificates or problems with your Certbot
installation that will lead to failure to renew.
(default: False)
-m EMAIL, --email EMAIL
Email used for registration and recovery contact. Use
comma to register multiple emails, ex:
u1@example.com,u2@example.com. (default: Ask).
--eff-email Share your e-mail address with EFF (default: None)
--no-eff-email Don't share your e-mail address with EFF (default:
None)
update_account:
Options for account modification
unregister:
Options for account deactivation.
--account ACCOUNT_ID Account ID to use (default: None)
install:
Options for modifying how a certificate is deployed
rollback:
Options for rolling back server configuration changes
--checkpoints N Revert configuration N number of checkpoints.
(default: 1)
plugins:
Options for the "plugins" subcommand
--init Initialize plugins. (default: False)
--prepare Initialize and prepare plugins. (default: False)
--authenticators Limit to authenticator plugins only. (default: None)
--installers Limit to installer plugins only. (default: None)
enhance:
Helps to harden the TLS configuration by adding security enhancements to
already existing configuration.
show_account:
Options useful for the "show_account" subcommand:
reconfigure:
Common options that may be updated with the "reconfigure" subcommand:

manual:
Authenticate through manual configuration or custom shell scripts. When
using shell scripts, an authenticator script must be provided. The
environment variables available to this script depend on the type of
challenge. $CERTBOT_DOMAIN will always contain the domain being
authenticated. For HTTP-01 and DNS-01, $CERTBOT_VALIDATION is the
validation string, and $CERTBOT_TOKEN is the filename of the resource
requested when performing an HTTP-01 challenge. An additional cleanup
script can also be provided and can use the additional variable
$CERTBOT_AUTH_OUTPUT which contains the stdout output from the auth
script. For both authenticator and cleanup script, on HTTP-01 and DNS-01
challenges, $CERTBOT_REMAINING_CHALLENGES will be equal to the number of
challenges that remain after the current one, and $CERTBOT_ALL_DOMAINS
contains a comma-separated list of all domains that are challenged for the
current certificate.
--manual-auth-hook MANUAL_AUTH_HOOK
Path or command to execute for the authentication
script (default: None)
--manual-cleanup-hook MANUAL_CLEANUP_HOOK
Path or command to execute for the cleanup script
(default: None)
nginx:
Nginx Web Server plugin
--nginx-server-root NGINX_SERVER_ROOT
Nginx server root directory. (default: /etc/nginx)
--nginx-ctl NGINX_CTL
Path to the 'nginx' binary, used for 'configtest' and
retrieving nginx version number. (default: nginx)
--nginx-sleep-seconds NGINX_SLEEP_SECONDS
Number of seconds to wait for nginx configuration
changes to apply when reloading. (default: 1)
null:
Null Installer
standalone:
Runs an HTTP server locally which serves the necessary validation files
under the /.well-known/acme-challenge/ request path. Suitable if there is
no HTTP server already running. HTTP challenge only (wildcards not
supported).
webroot:
Saves the necessary validation files to a .well-known/acme-challenge/
directory within the nominated webroot path. A seperate HTTP server must
be running and serving files from the webroot path. HTTP challenge only
(wildcards not supported).
--webroot-path WEBROOT_PATH, -w WEBROOT_PATH
public_html / webroot path. This can be specified
multiple times to handle different domains; each
domain will have the webroot path that preceded it.
For instance: `-w /var/www/example -d example.com -d
www.example.com -w /var/www/thing -d thing.net -d
m.thing.net` (default: Ask)
--webroot-map WEBROOT_MAP
JSON dictionary mapping domains to webroot paths; this
implies -d for each entry. You may need to escape this
from your shell. E.g.: --webroot-map
'{"eg1.is,m.eg1.is":"/www/eg1/", "eg2.is":"/www/eg2"}'
This option is merged with, but takes precedence over,
-w / -d entries. At present, if you put webroot-map in
a config file, it needs to be on a single line, like:
webroot-map = {"example.com":"/var/www"}. (default:
{})
