Zabbix:Installation A

This procedure applies to Zabbix v.2.4 on CentOS6

Install Zabbix

1. Follow RedHat/CentOS installation procedure from Zabbix documentation

https://www.zabbix.com/documentation/2.4/manual/installation/install_from_packages#red_hat_enterprise_linuxcentos

Note: It is possible that you might get the following error while starting httpd on a new CentOS installation:

# service httpd start
Starting httpd: httpd: apr_sockaddr_info_get() failed for myZabbixHost
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

Make sure to configure your hostname "myZabbixHost" to /etc/hosts

2. Configure services to automatically starts on reboot of the server

# chkconfig mysqld on
# chkconfig zabbix-server on
# chkconfig zabbix-agent on
# chkconfig httpd on

3. Disable SELinux

# setenforce 0

Edit /etc/selinux/config and set SELINUX to disabled:

# vi /etc/selinux/config
SELINUX=disabled

4. Configure the Zabbix frontend

Follow the procedure in the section Installing frontend from Zabbix documentation

https://www.zabbix.com/documentation/2.4/manual/installation/install#installing_zabbix_web_interface

5. Login to Zabbix frontend

In your browser, open Zabbix URL: http://<server_ip_or_name>/zabbix

The default user name is Admin, password zabbix

Install NET-SNMP

# yum install net-snmp-utils
# yum install net-snmp-perl
# yum install snmptt

Note: perl-Net-SNMP will be installed together with snmptt

Install MIBs

1. Get the "install_mibs.sh" script:

# wget http://download.distribution.telcobridges.com/mibs/install_mibs.sh
# chmod +x install_mibs.sh

2. Run "install_mibs.sh" script with no argument to get the mibs path configured on your system:

# ./install_mibs.sh
./install_mibs.sh <MibPath>
Mibs paths returned by snmptranslate:
init_mib: Seen MIBDIRS: Looking in '/root/.snmp/mibs:/usr/share/snmp/mibs' for mib dirs ...

3. Install the mibs files to the MIBDIRS path (ex./usr/share/snmp/mibs):

# ./install_mibs.sh /usr/share/snmp/mibs

The installation of NET-SNMP already comes with defaults mibs. The script install only the mibs that are not included in the default NET-SNMP package and that are needed by the TB snmp zabbix templates:

• TB-MIB-2014.mib (TB-MIB)
• rfc-2495.mib (DS1-MIB)
• rfcperfhist.mib (definition used by rfc-2495.mib)

Note: If for some reason your NET-SNMP does not contain all the required mibs, you can download all the mibs from http://download.distribution.telcobridges.com/mibs and copy them to your MIBDIRS path.

4. Configure snmp.conf (if the file does not exist, create the file with only the following line):

# vi /etc/snmp/snmp.conf
mibs +ALL

Configure SNMP traps

translate_log_trap_oid = 2
net_snmp_perl_enable = 1

Install TelcoBridges snmptt.conf

# wget http://download.distribution.telcobridges.com/zabbix/snmptt.conf
