42 Chapter 3 Installing ColdFusion Server in Linux
To install SNMP in Red Hat:
The ColdFusion Server MIB Agent uses the Dynamic Module approach of
UCD-SNMP 4.2. To use the MIB Agent, you must ensure that UCD-SNMP 4.2.1 or
higher is installed on your system.
1 Download UCD-SNMP 4.2.1 from http://net-snmp.sourceforge.net(download):
• For Red Hat 6.2, download ucd-snmp-4.2.1-2.rh62.i386.rpm
• For Red Hat 7.0, download ucd-snmp-4.2.1-1.rh7.0.i386.rpm
Note
By default, UCD-SNMP installs into the /usr/sbin directory.
2 Install UCD-SNMP 4.2.1 on your system. If installation of UCD-SNMP 4.2.1 RPM
requires openssl, you can download it at http://rpmfind.net.
When you install the MIB Agent, the ColdFusion Server installation asks whether you
want to replace the current snmpd.conf with a version of snmpd.conf that will make
ColdFusion MIB information accessible.
If you answer Yes, the current copy of snmpd.conf in /etc/snmp is renamed to
snmp.conf_original, and the ColdFusion version of snmpd.conf is inserted into /etc/
snmp. If you answer No, the snmpd.conf_macromedia file is placed into /etc/snmp.
You must then merge the content from snmpd.conf_macromedia into snmpd.conf
to make ColdFusion MIB information accessible.
After finishing the ColdFusion Server installation, you must configure your system to
use MIB features. For more information, see “Configuring SNMP MIB” on page 51.
Important Network Considerations
Keep the following table important considerations in mind when configuring your
network before a ColdFusion Server installation:
• ClusterCATS requires that the group
btcats exist. It attempts to create this group
during the ColdFusion installation using
groupadd. If you are using NIS or NIS+,
ensure that either nsswitch.conf allows for group resolution from the group file,
or the group btcats gets created in NIS/NIS+ before installing ClusterCATS.
• ClusterCATS requires that you enable multicast on all network adapters. To
enable multicast on an adapter, enter the following command:
ifconfig eth0 multicast
• In this example, the adapter is eth0; enter an appropriate adapter name for your
configuration.
• In an optimal production environment, each ColdFusion Server application
should be hosted on a dedicated server. A database, mail, or other server should
not reside on the same server as ColdFusion Server.
• If you intend to install ClusterCATS, you must first prepare your server. For
instructions, see “Preparing Your Server for ClusterCATS” on page 135.
