The Apache HTTP Server
|
|
indexterm:[httpd,Apache HTTP Server] The web server available in {MAJOROS} is the Apache HTTP server daemon, `httpd`, an open source web server developed by the link:++https://www.apache.org/++[Apache Software Foundation]. In Fedora 19 the Apache server was updated to [application]*Apache HTTP Server 2.4*. This section describes the basic configuration of the `httpd` service, and covers some advanced topics such as adding server modules, setting up virtual hosts, or configuring the secure HTTP server.
|
|
There are important differences between the Apache HTTP Server 2.4 and version 2.2, and if you are upgrading from a release prior to Fedora 19, you will need to update the `httpd` service configuration accordingly. This section reviews some of the newly added features, outlines important changes, and guides you through the update of older configuration files.

Notable Changes
|
|
indexterm:[Apache HTTP Server,version 2.4,changes] The Apache HTTP Server version 2.4 has the following changes compared to version 2.2:
|
|
httpd Service Control
|
|
With the migration away from SysV init scripts, server administrators should switch to using the [command]#apachectl# and [command]#systemctl# commands to control the service, in place of the [command]#service# command. The following examples are specific to the `httpd` service.
|
|
The command:
|
|
service httpd graceful
|
|
is replaced by
|
|
apachectl graceful
|
|
The `systemd` unit file for `httpd` has different behavior from the init script as follows:
|
|
A graceful restart is used by default when the service is reloaded.
|
|
A graceful stop is used by default when the service is stopped.
|
|
service httpd configtest
|
|
apachectl configtest
|
|
Private /tmp
|
|
To enhance system security, the `systemd` unit file runs the `httpd` daemon using a private `/tmp` directory, separate to the system `/tmp` directory.
|
|
Configuration Layout
|
|
Configuration files which load modules are now placed in the `/etc/httpd/conf.modules.d` directory. Packages that provide additional loadable modules for `httpd`, such as [package]*php*, will place a file in this directory. Any configuration files in the `conf.modules.d` directory are processed before the main body of `httpd.conf`. Configuration files in the `/etc/httpd/conf.d` directory are now processed after the main body of `httpd.conf`.
