Testing of certs failed randomly when the web server was still
returning old certs even after the reload was "complete". This was
because the reload commands send process signals and do not wait
for the worker processes to restart. This commit adds log watchers
which wait for the worker processes to be restarted.
- Use an acme user and group, allow group override only
- Use hashes to determine when certs actually need to regenerate
- Avoid running lego more than necessary
- Harden permissions
- Support "systemctl clean" for cert regeneration
- Support reuse of keys between some configuration changes
- Permissions fix services solves for previously root owned certs
- Add a note about multiple account creation and emails
- Migrate extraDomains to a list
- Deprecate user option
- Use minica for self-signed certs
- Rewrite all tests
I thought of a few more cases where things may go wrong,
and added tests to cover them. In particular, the web server
reload services were depending on the target - which stays alive,
meaning that the renewal timer wouldn't be triggering a reload
and old certs would stay on the web servers.
I encountered some problems ensuring that the reload took place
without accidently triggering it as part of the test. The sync
commands I added ended up being essential and I'm not sure why,
it seems like either node.succeed ends too early or there's an
oddity of the vm's filesystem I'm not aware of.
- Fix duplicate systemd rules on reload services
Since useACMEHost is not unique to every vhost, if one cert
was reused many times it would create duplicate entries in
${server}-config-reload.service for wants, before and
ConditionPathExists
nginx -t not only verifies configuration, but also creates (and chowns)
files. When the `nginx-config-reload` service is used, this can cause
directories to be chowned to `root`, causing nginx to fail.
This moves the nginx -t command into a second ExecReload command, which
runs as nginx's user. While fixing above issue, this will also cause the
configuration to be verified when running `systemctl reload nginx`, not
only when restarting the dummy `nginx-config-reload` unit. The latter is
mostly a workaround for missing features in our activation script
anyways.
After the recent rewrite, enabled extensions are passed to php programs
through an extra ini file by a wrapper. Since httpd uses shared module
instead of program, the wrapper did not affect it and no extensions
other than built-ins were loaded.
To fix this, we are passing the extension config another way – by adding it
to the service's generated config.
For now we are hardcoding the path to the ini file. It would be nice to add
the path to the passthru and use that once the PHP expression settles down.
