25.4. Apache HTTP Server Configuration
The HTTP Configuration Tool allows you to configure the
/etc/httpd/conf/httpd.confconfiguration file for the Apache HTTP Server. It does not use the old
access.confconfiguration files; leave them empty. Through the graphical interface, you can configure directives such as virtual hosts, logging attributes, and maximum number of connections. To start the HTTD Configuration Tool, click on
System > Administration > Server Settings > HTTP.
Only modules provided with Red Hat Enterprise Linux can be configured with the HTTP Configuration Tool. If additional modules are installed, they can not be configured using this tool.
Do not edit the
/etc/httpd/conf/httpd.confconfiguration file by hand if you wish to use this tool. The HTTP Configuration Tool generates this file after you save your changes and exit the program. If you want to add additional modules or configuration options that are not available in HTTP Configuration Tool, you cannot use this tool.
The general steps for configuring the Apache HTTP Server using the HTTP Configuration Tool are as follows:
- Configure the basic settings under the Main tab.
- Click on the Virtual Hosts tab and configure the default settings.
- Under the Virtual Hosts tab, configure the Default Virtual Host.
- To serve more than one URL or virtual host, add any additional virtual hosts.
- Configure the server settings under the Server tab.
- Configure the connections settings under the Performance Tuning tab.
- Copy all necessary files to the
- Exit the application and select to save your settings.
25.4.1. Basic Settings
Use the Main tab to configure the basic server settings.
Figure 25.1. Basic Settings
Enter a fully qualified domain name that you have the right to use in the Server Name text area. This option corresponds to the
ServerNamedirective sets the hostname of the Web server. It is used when creating redirection URLs. If you do not define a server name, the Web server attempts to resolve it from the IP address of the system. The server name does not have to be the domain name resolved from the IP address of the server. For example, you might set the server name to www.example.com while the server's real DNS name is foo.example.com.
Enter the email address of the person who maintains the Web server in the Webmaster email address text area. This option corresponds to the
httpd.conf. If you configure the server's error pages to contain an email address, this email address is used so that users can report a problem to the server's administrator. The default value is root@localhost.
Use the Available Addresses area to define the ports on which the server accepts incoming requests. This option corresponds to the
httpd.conf. By default, Red Hat configures the Apache HTTP Server to listen to port 80 for non-secure Web communications.
Click the Add button to define additional ports on which to accept requests. A window as shown in Figure 25.2, “Available Addresses” appears. Either choose the Listen to all addresses option to listen to all IP addresses on the defined port or specify a particular IP address over which the server accepts connections in the Address field. Only specify one IP address per port number. To specify more than one IP address with the same port number, create an entry for each IP address. If at all possible, use an IP address instead of a domain name to prevent a DNS lookup failure. Refer to http://httpd.apache.org/docs/2.2/dns-caveats.html for more information about Issues Regarding DNS and Apache.
Entering an asterisk (*) in the Address field is the same as choosing Listen to all addresses. Clicking the Edit button in the Available Addresses frame shows the same window as the Add button except with the fields populated for the selected entry. To delete an entry, select it and click the Delete button.
If you set the server to listen to a port under 1024, you must be root to start it. For port 1024 and above,
httpdcan be started as a regular user.
