Cluster Server 7.3.1 Bundled Agents Reference Guide - Linux

Running two instances of httpd for Linux

This example shows how two instances 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:

system sysa
system sysb
group Apache_1 (
SystemList = { sysa ,sysb}
AutoStartList = { sysa}
)

Apache myapacheWeb (
httpdDir = "/mnt/apache/bin"
ConfigFile = "/mnt/apache/conf/httpd.conf"
HostName = "server1.example.com"
Port = 80
)

IP myapacheIP(
Device = "eth0"
Address="192.168.50.50"
NetMask="255.255.255.0"
)

NIC myapacheNIC(
Device="eth0"
NetworkHosts={"172.29.9.178","172.29.9.179"}
)

Mount myapacheMnt(
MountPoint="/mnt/apache/"
BlockDevice="/dev/sdd2"
FSType = ext3
FsckOpt = "-y"
)

myapacheIP requires myapacheNIC
myapacheWeb requires myapacheIP
myapacheWeb requires myapacheMnt

group Apache_2 (
SystemList = { sysa,sysb}
AutoStartList = { sysa}
)

Apache myapacheWeb2(
httpdDir = "/mnt/apache1/bin"
ConfigFile = "/mnt/apache1/conf/httpd.conf"
HostName = "server2.example.com"
Port = 8080
)

IP myapacheIP2(
Device = "eth1"
Address="192.168.60.50"
NetMask="255.255.255.0"
)

NIC myapacheNIC2(
Device="eth1"
)

Mount myapacheMnt2(
MountPoint="/mnt/apache1/"
BlockDevice="/dev/sdc3"
FSType = ext3
FsckOpt = "-y"
)

myapacheIP2 requires myapacheNIC2
myapacheWeb2 requires myapacheIP2
myapacheWeb2 requires myapacheMnt2
