2. The machine's exact system time is maintained by synchronizing with a time
server. This is necessary because parts of the HTTP protocol depend on the correct
time. See Chapter 32, Time Synchronization with NTP (page 609) to learn more
about this topic.
3. The latest security updates are installed. If in doubt, run a YaST Online Update.
4. The default Web server port (port 80) is opened in the firewall. For this, configure
the SUSEFirewall2 to allow the service HTTP Server in the external zone. This
can be done using YaST. Section 43.4.1, "Configuring the Firewall with YaST"
(page 829) gives details.
40.1.2 Installation
Apache on SUSE Linux Enterprise Server is not installed by default. To install it, start
YaST and select Software > Software Management. Now choose Filter > Patterns and
select Web and LAMP Server under Primary Functions. Confirm the installation of the
dependent packages to finish the installation process.
Apache is installed with a standard, predefined configuration that runs "out of the box".
The installation includes the multiprocessing module apache2-prefork as well
the PHP5 module. Refer to Section 40.4, "Installing, Activating, and Configuring
Modules" (page 763) for more information about modules.
40.1.3 Start
To start Apache and make sure that it is automatically started during boot, start YaST
and select System > System Services (Runlevel). Search for apache2 and Enable the
service. The Web server starts immediately. By saving your changes with Finish, the
system is configured to automatically start Apache in runlevels 3 and 5 during boot.
For more information about the runlevels in SUSE Linux Enterprise Server and a de-
scription of the YaST runlevel editor, refer to Section 20.2.3, "Configuring System
Services (Runlevel) with YaST" (page 400).
To start Apache using the shell, run rcapache2 start. To make sure that Apache
is automatically started during boot in runlevels 3 and 5, use chkconfig -a
apache2.
