Apache

We use Apache as our web server.

Configuration

The Webserver can be configured with the .htaccess file in your webroot which in most cases is sufficent. But some directives are not available in the .htaccess context and they therfore must be configured in the ~/cnf/apache.conf file which is included on vhost level.

Hint

The use of .htaccess should be preferred if possible, as incorrect configurations do not result in the web server no longer being able to be started in the event of a server restart.

Hint

After changes in ~/cnf/apache.conf you need to apply the configuration with apache-apply

Examples

Warning

The code blocks mentioned here serve as an example. Please check yourself if everything works correctly, especially if you have other configurations in your .htaccess file.

Custom Webroot

By default, the webroot directory is choosen according vendor recommendations, depending on the selected type. Some deployment workflows require other locations, which you can select through the webroot string within the Custom JSON Website Level Configuration:

{
  "webroot": "deploy/current/html"
}

Warning

The directory specified here needs to be a real directory. Symlinks are not allowed. This applies only to the last directory though (in the example above, current can be a symlink but html cannot).

Custom Default Webroot

The “Custom Default Webroot” differs from the “Custom Webroot”. The “Custom Default Webroot” is the webroot used when a website on a server is accessed that does not exist or for special features.

The files provided on your Server by default can be copied from the default webroot git repository.

To customize a custom default webroot please add the following to the “Custom JSON” on your Server and customize the values accordingly for your own git repository.

{
  "website::default::webroot::gitsource": "git@work.opsone.ch:open/default-webroot.git",
  "website::default::webroot::gitrevision": "d00433e671d9eec99ba8d56c3a08c4a7921c32b7",
  "website::default::webroot::gitkey": "-----BEGIN OPENSSH PRIVATE KEY-----\zAXktdjEABGAaC1AArZ5v...\n-----END OPENSSH PRIVATE KEY-----"
}

Listen

By default, apache will bind to the primary IP address of the eth0 interface and the 80/443 port. You can specify listen options explicitly per website, for example to use in concunction with Varnish.

The following options are available within the Custom JSON Website Level Configuration:

{
  "listen_ipv4_address": "127.0.0.1",
  "listen_ipv4_port": 8080,
  "listen_ipv6_address": "::1",
  "listen_ipv6_port": 8080
}
