The `ServerName` directive needs to be set inside the default SSL vhost,
as this property does not get inherited from the global configuration,
and it is needs to be set in order for SNI to work correctly.
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_server_tokens` variable can now be set, which controls the
value of the `ServerTokens` directive. If the variable is set, the
`ServerTokens` directive will be added to the `00-servername.conf` file.
The *apache* role installs and configures the Apache HTTPD server and
its *mod_ssl* module. It currently only works on Fedora/RHEL-based
distributions.
