Sample configurations

Running two versions of httpd for Linux

This example shows how two versions of httpd can run from different locations. In group Apache_1, httpd runs from Port 80, the default location. The configuration file in /usr/local/apache/conf/httpd.conf should indicate DocumentRoot, address, port, and other parameters. In group Apache_2, httpd runs from /home/web/apache. The PID file for this is created in /home/web/apache/logs/httpd.pid. The configuration file in /home/web/apache/conf/httpd.conf should define parameters for running this version of httpd.

Each Apache resource requires an online IP resource. In this example, each Apache resource requires an online mount resource to mount block devices from disks reserved by the Disk Reservation agent.
