How to configure Zabbix for Linux host monitoring

This article mainly introduces that Zabbix monitoring server has been configured. to use Zabbix to monitor Linux hosts, you can refer to the following instructions:

The Zabbix monitoring server has been configured. now you need to use Zabbix to monitor Linux hosts.

Specific operations:

The following operations are performed on the monitored Linux host. the CentOS 6. x system is used as an example.

1. configure the firewall to enable TCP and UDP ports 10050 and 10051

Vi/etc/sysconfig/iptables # Edit the firewall configuration file

-A input-s 192.168.21.127-m state -- state NEW-m tcp-p tcp -- dport 10050: 10051-j ACCEPT

-A input-s 192.168.21.127-m state -- state NEW-m udp-p udp -- dport 10050: 10051-j ACCEPT

: Wq! # Save and exit

Service iptables restart # restart the firewall to make the configuration take effect

Note: 192.168.21.127 is the IP address of the Zabbix server, indicating that the port is only open to this IP address. to open it to all IP addresses, the rules are as follows:

-A input-m state -- state NEW-m tcp-p tcp -- dport 10050: 10051-j ACCEPT

-A input-m state -- state NEW-m udp-p udp -- dport 10050: 10051-j ACCEPT

II. disable SELINUX

Vi/etc/selinux/config

# SELINUX = enforcing # Comment out

# SELINUXTYPE = targeted # Comment out

SELINUX = disabled # Add

: Wq! # Save and exit

Setenforce 0 # Make the configuration take effect immediately

3. install the Zabbix client

1. download zabbix software package

Zabbix-2.2.6

Http://jaist.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/2.2.6/zabbix-2.2.6.tar.gz

Upload zabbix-2.2.6.tar.gz to the/usr/local/src directory on the server.

2. add a user

Groupadd zabbix # Create a user group zabbix

Useradd zabbix-g zabbix-s/bin/false # create user zabbix and add user zabbix to user group zabbix

3. install Zabbix

Ln-s/usr/local/lib/libiconv. so.2/usr/lib/libiconv. so.2 # Add a soft connection

/Sbin/ldconfig # Make the configuration take effect immediately

Cd/usr/local/src

Tar zxvf zabbix-2.2.6.tar.gz

Cd zabbix-2.2.6

./Configure -- prefix =/usr/local/zabbix -- enable-agent # configuration

Make # compile

Make install # install

Ln-s/usr/local/zabbix/sbin/*/usr/local/sbin/# add soft system connection

Ln-s/usr/local/zabbix/bin/*/usr/local/bin/# Add a soft system connection

Note: to compile and install the software, you must first install the compilation tool and other system software packages. CentOS uses the following command to install the software:

Yum install apr * autoconf automake bison cloog-ppl compat * cpp curl-devel fontconfig-devel freetype * freetype-devel gcc-c ++ gtk +-devel gd gettext -devel glibc kernel-headers keyutils-libs-devel krb5-devel libcom_err-devel libpng * libjpeg * libsepol-devel kernel-devel libstdc ++-devel libtool * libgomp lib2 libxml2-devel libXpm * libtiff * libX * make mpfr ncurses * ntp openssl-devel patch pcre-devel perl php-common php-gd yycoreutils ppl telnet t1lib t1lib * nasm * wget zlib-devel

4. Add the port corresponding to the zabbix service

Echo 'zabbix-agent 10050/tcp # zabbix agent'>/etc/services

Echo 'zabbix-agent 10050/udp # zabbix agent'>/etc/services

Echo 'zabbix-trapper 10051/tcp # zabbix trapper'>/etc/services

Echo 'zabbix-trapper 10051/udp # zabbix trapper'>/etc/services

Or

Vi/etc/services # edit and add the following code at the end

# Zabbix

Zabbix-agent 10050/tcp # Zabbix Agent

Zabbix-agent 10050/udp # Zabbix Agent

Zabbix-trapper 10051/tcp # Zabbix Trapper

Zabbix-trapper 10051/udp # Zabbix Trapper

: Wq! # Save and exit

5. modify the Zabbix configuration file

Vi/usr/local/zabbix/etc/zabbix_agentd.conf # Edit

Server = 192.168.21.127

Include =/usr/local/zabbix/etc/zabbix_agentd.conf.d/

UnsafeUserParameters = 1 # enable custom key

: Wq! # Save and exit

Note: 192.168.21.127 is the IP address of the Zabbix server.

6. add the boot script

Cp/usr/local/src/zabbix-2.2.6/misc/init. d/fedora/core/zabbix_agentd/etc/rc. d/init. d/zabbix_agentd

Vi/etc/rc. d/init. d/zabbix_agentd # Edit

BASEDIR =/usr/local/zabbix/# Zabbix installation directory

: Wq! # Save and exit

Chmod + x/etc/rc. d/init. d/zabbix_agentd # add the script execution permission

Chkconfig zabbix_agentd on # Add boot start

Service zabbix_agentd start # start the Zabbix client

Ps ax | grep zabbix_agentd # check whether the Zabbix client is running normally

Netstat-utlnp | grep zabbix # check whether the Zabbix client is running properly

4. test whether the communications between the Zabbix client and the Zabbix server are normal.

Run the following code on the Zabbix server:

/Usr/local/zabbix/bin/zabbix_get-s192.168.21.128-p10050-k "system. uptime"

5049866 # if data is displayed, the communication is normal.

Note: 192.168.21.128 is the IP address of the Zabbix client.

5. Add monitoring for Linux hosts

Open in the browser:

Http: // 192.168.21.127/zabbix/# Zabbix server access address

Select: Template OS Linux

Add point

Archive

So far, Zabbix has completed Linux host monitoring.
