Installing the Linux Zabbix Agent, getting the files from monitor.rice.edu

For servers in a closed network, the easiest way to install the Zabbix agent is probably
to download the files from monitor.rice.edu to a local workstation, then copy them over to
/tmp/ZABBIX/ on your server and install from there.
This example assumes we downloaded the files and then copied to EA12.rice.edu:/tmp/ZABBIX/

This installs just the Linux agent program; zabbix_agentd for monitoring. The default
config file will be placed at /etc/opt/zabbix/zabbix_agentd.conf. Everything else is specified
in the config file.

Download zabbix agent and files from monitor.rice.edu

From any section page on monitor
click the tab on the bottom labeled "Get the zabbix agents here"

Select from these options, and download the appropriate files

Linux agent
RH5 32bit statically linked agent
RH5 64bit statically linked agent
Start/Stop script
Win32 agent
Win64 agent
Config file
  • Copy all files to client you are installing agent on, into /tmp/ZABBIX/*

Setup Zabbix user/groups on the new client

You will need to sudo to root to do the following:

  • Verify/add Zabbix user/groups on Linux client:*

This may already have been done as part of the initial install. Verify and do setup
if necessary.

egrep '^zabbix:' /etc/passwd >/dev/null || cat - >> /etc/passwd << EOF
zabbix:x:906:906:Zabbix User:/home/zabbix:/bin/bash
EOF
egrep '^zabbix:' /etc/group >/dev/null || cat - >> /etc/group << EOF
zabbix:x:906:
EOF
pwconv
  • Make home dir for zabbix, copy in zabbix_agentd *

Wherever the local admins accounts are, make one for Zabbix.

mkdir /home/zabbix 
cp -p /tmp/ZABBIX/zabbix_agentd /home/zabbix
chown -R zabbix /home/zabbix
  • Setup Zabbix config file *

The default init script checks for /etc/opt/zabbix/zabbix_agentd.conf, and if found this file will be used instead of the default config file.

mkdir /etc/opt/zabbix
cp -p /tmp/ZABBIX/zabbix_agentd.conf /etc/opt/zabbix
  • Install/activate Zabbix init script:
cp -pi /tmp/ZABBIX/zabbix_agent_init /etc/init.d/zabbix_agent
chkconfig zabbix_agent on
chkconfig --list zabbix_agent
  • Create local var directory for log and pid files:
mkdir /var/opt/zabbix
chown -R zabbix:zabbix /var/opt/zabbix
  • Verify IPTABLES for Zabbix connections

Be sure IPTABLES is updated to accept connections on port 10050, from 10.129.92.52. May be already
done with sitedisk iptables when your system was first installed. Check for a line allowing
connections from 10.129.92.52 (monitor.rice.edu) to port 10050 on client.

## Add this IF needed to iptables
## accept Zabbix agent connections on port 10050, from zabbix server
## at 10.129.92.52
-A INPUT -p tcp -m tcp --dport 10050 -s 10.129.92.52/32 -j ACCEPT
  • Update /etc/services file if necessary:

This may have already been added to /etc/services at initial install. Check for and
add if necessary.

## Zabbix services
zabbix_agent            10050/tcp               # Zabbix Agent
zabbix_trap             10051/tcp               # Zabbix Trap
#

Start zabbix_agent on client

Fire it up:

/etc/init.d/zabbix_agent start

Define monitoring for new client on monitor.rice.edu
