Logging to syslog will allow messages to be aggregated in the central
server (Loki now, Victoria Logs eventually), so I don't have to SSH into
the web server to check for errors.
Using files for certificates and private keys is less than ideal.
The only way to "share" a certificate between multiple hosts is with
symbolic links, which means the configuration policy has to be prepared
for each managed system. As we're moving toward a much more dynamic
environment, this becomes problematic; the host-provisioner will never
be able to copy a certificate to a new host that was just created.
Further, I have never really liked the idea of storing certificates and
private keys in Git anyway, even if it is in a submodule with limited
access.
By default, per-user directories (i.e. `/~username/`) are disabled in
Fedora's configuration of Apache. This commit introduces a new variable,
`apache_userdir`, which can be used to enable this feature. It should be
set to a string other than *disabled*, which is the path under users'
home directories that will be served, if it is accessible. Normally, the
value would be `public_html`.
If another role that depends on the *apache* role accidentally creates
an invalid configuration, it will be impossible to correct it by
subsequent invocations of its playbook. This is because the *apache*
role always tries to start the service, which will fail if the
configuration is invalid, thus aborting the playbook. With this early
abort, there is no way for later tasks to correct the error.
Playbooks that include the *apache* role should have a task that is
executed after all the roles have been applied to ensure the service is
running.
The *apache* role installs and configures the Apache HTTPD server and
its *mod_ssl* module. It currently only works on Fedora/RHEL-based
distributions.
