let's encrypt部署免费泛域名证书
环境说明
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.5.1804 (Core)

安装
此处使用yum安装certbot
#certbot 包在epel源中，所以此处需要先安装epel源
#另一种安装方法直接下载 wget https://dl.eff.org/certbot-auto
#因为域名都在cloudflare上，所以此处安装certbot-dns-cloudflare插件通过API来自动添加txt记录
#https://certbot-dns-cloudflare.readthedocs.io/en/stable/ 官方配置文档
yum -y install epel-release
yum -y install certbot
source /opt/eff.org/certbot/venv/bin/activate
pip install certbot-dns-cloudflare
certbot certonly --agree-tos --manual-public-ip-logging-ok --dns-cloudflare --dns-cloudflare-credentials cloudflare.ini --dns-cloudflare-propagation-seconds 30 -d *.xleon.top -d xleon.top --server https://acme-v02.api.letsencrypt.org/directory --email xxx@qq.com -n
#如果不使用插件的话可以用下面的命令来生成泛域名证书
./certbot-auto certonly --manual -d *.example.com -d example.com --preferred-challenges dns-01 --server https://acme-v02.api.letsencrypt.org/directory
renew
let’s encrypt的有效期为90天，到期之后需要重新更新证书，可以使用renew命令,写个cron任务
certbot renew -q --deploy-hook /path/to/script
#--deploy-hook 为更新成功后会执行的脚本 --pre-hook为更新前脚本 --post-hook为更新后脚本
如果您手动更新所有证书，该 --force-renewal标志可能会有所帮助; 它会导致在考虑续订时忽略证书的到期时间，并尝试更新每个已安装的证书，而不管其年龄如何。（此参数不适合每天运行，因为每个证书将每天续订，这将快速进入证书颁发机构速率限制。50次）
如果您确定此命令在没有人为干预的情况下成功执行，您可以添加命令crontab（因为证书只有在确定接近到期时才会更新，命令可以定期运行，例如每周或每个天）。在这种情况下，您可能希望使用-q或--quiet标志来静音除错误之外的所有输出

certbot 命令行选项
Certbot command-line options
Certbot supports a lot of command line options. Here’s the full list, from certbot --help 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-path or --cert-name)
delete Delete a certificate
manage your account with Let's Encrypt:
register Create a Let's Encrypt ACME account
--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:
-2)
--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 apply. For multiple domains you can
use multiple -d flags or enter a comma separated list
of domains as a parameter. The first domain provided
will be the subject CN of the certificate, and all
domains will be Subject Alternative Names on the
certificate. The first domain will also be used in
some software user interfaces and as the file paths
for the certificate and related material unless
otherwise specified or you already have a certificate
with the same name. In the case of a name collision it
will append a number like 0001 to the file path name.
(default: Ask)
--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 (default: False)
--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 "tls-
sni-01,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: [])
--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/0.28.0
(certbot(-auto); OS_NAME OS_VERSION) Authenticator/XXX
Installer/YYY (SUBCOMMAND; flags: FLAGS)
Py/major.minor.patchlevel). 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)
--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)
--os-packages-only (certbot-auto only) install OS package dependencies
and then stop (default: False)
--no-self-upgrade (certbot-auto only) prevent the certbot-auto script
from upgrading itself to newer released versions
(default: Upgrade automatically)
--no-bootstrap (certbot-auto only) prevent the certbot-auto script
from installing OS-level dependencies (default: Prompt
to install OS-wide dependencies, but exit if the user
says 'No')
-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)
--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: Ask)
--no-redirect Do not automatically redirect all HTTP traffic to
HTTPS for the newly authenticated vhost. (default:
Ask)
--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.
--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, and allow certbot-
auto execution on experimental platforms (default:
False)
--no-verify-ssl Disable verification of the ACME server's certificate.
(default: False)
--tls-sni-01-port TLS_SNI_01_PORT
Port used during tls-sni-01 challenge. This only
affects the port Certbot listens on. A conforming ACME
server will still attempt to connect on port 443.
(default: 443)
--tls-sni-01-address TLS_SNI_01_ADDRESS
The address the server listens to during tls-sni-01
challenge. (default: )
--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: )
--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 auth --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
update_symlinks Recreate symlinks in your /etc/letsencrypt/live/
directory
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 all certificates (or more
precisely, certificate lineages) you have previously obtained if they are
close to expiry, and print a summary of the results. By default, 'renew'
will reuse the options used to create obtain or most recently successfully
renew each certificate lineage. You can try it with `--dry-run` first. For
more fine-grained control, you can renew individual lineages with the
`certonly` subcommand. 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. 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. 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. 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: True)
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. (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 & modification
--register-unsafely-without-email
Specifying this flag enables registering an account
with no email address. This is strongly discouraged,
because in the event of key loss or account compromise
you will irrevocably lose access to your account. You
will also be unable to receive notice about impending
expiration or revocation of your certificates. Updates
to the Subscriber Agreement will still affect you, and
will be effective 14 days after posting an update to
the web site. (default: False)
--update-registration
With the register verb, indicates that details
associated with an existing registration, such as the
e-mail address, should be updated, rather than
registering a new account. (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)
unregister:
Options for account deactivation.
--account ACCOUNT_ID Account ID to use (default: None)
install:
Options for modifying how a certificate is deployed
config_changes:
Options for controlling which changes are displayed
--num NUM How many past revisions you want to be displayed
(default: None)
rollback:
Options for rolling back server configuration changes
--checkpoints N Revert configuration N number of checkpoints.
(default: 1)
plugins:
Options for 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)
update_symlinks:
Recreates certificate and key symlinks in /etc/letsencrypt/live, if you
changed them by hand or edited a renewal configuration file
enhance:
Helps to harden the TLS configuration by adding security enhancements to
already existing configuration.
plugins:
Plugin Selection: Certbot client supports an extensible plugins

--dns-sakuracloud-credentials DNS_SAKURACLOUD_CREDENTIALS
Sakura Cloud credentials file. (default: None)
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. When performing a TLS-
SNI-01 challenge, $CERTBOT_SNI_DOMAIN will contain the SNI name for which
the ACME server expects to be presented with the self-signed certificate
located at $CERTBOT_CERT_PATH. The secret key needed to complete the TLS
handshake is located at $CERTBOT_KEY_PATH. 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.
--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)
--manual-public-ip-logging-ok
Automatically allows public IP logging (default: Ask)
nginx:
Nginx Web Server plugin
--nginx-server-root NGINX_SERVER_ROOT
Nginx server root directory. (default: /etc/nginx or
/usr/local/etc/nginx)
--nginx-ctl NGINX_CTL
Path to the 'nginx' binary, used for 'configtest' and
retrieving nginx version number. (default: nginx)
null:
Null Installer
standalone:
Spin up a temporary webserver
webroot:
Place files in webroot directory
--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:
{})
