nginx や apacheが起動していても大丈夫。
certbot はhttpd が起動しても、ちゃんとなんとかしてくれる。
/usr/bin/certbot -q renew --pre-hook "service nginx stop" --post-hook "service nginx start"
pre-hook や post-hookで再起動を仕込めるので全く問題ないんですね。
man によると
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)
--renew-hook RENEW_HOOK
Command to be run in a shell once for each
successfully renewed certificate. For this command,
the shell variable $RENEWED_LINEAGE will point to the
config live subdirectory containing the new certs and
keys; the shell variable $RENEWED_DOMAINS will contain
a space-delimited list of renewed cert domains
(default: None)
--disable-hook-validation
Ordinarily the commands specified for --pre-hook
/--post-hook/--renew-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)
hook
hook組み合わせるをシンプルなコマンドで定期的な証明書の更新をできるので楽ですね。
いつまで certbot と letsencrypt は無料でSSL配ってくれるんでしょうね。。。。
数年後には有料化されちゃったり、登録の煩雑化されたりしないですよね。心配だ
