How to set up Zabbix monitoring Linux host

Instructions:

The Zabbix monitoring server has been configured. Now you need to use Zabbix to monitor the Linux host.

Specific operations:

The following operations are performed on the monitored Linux host. Here we take the CentOS 6.x system as an example.

1. Configure the firewall and open 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 effective

Explanation: 192.168.21.127 is Zabbix The IP address of the server means that the port is only open to this IP. If it is to be open to all IPs, 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

2. Close 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 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 server/usr/local/src directory

2. Add user

groupadd zabbix #Create 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 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 system soft connection

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

Note: Compiling and installing software needs to be installed first Compilation tools and other system software packages, CentOS uses the following command to install

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

Note: 192.168.21.127 is the Zabbix server IP address

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 script execution Permissions

chkconfig zabbix_agentd on #Add boot startup

service zabbix_agentd start #Start Zabbix client

ps ax|grep zabbix_agentd #Check whether Zabbix client is running normally

netstat -utlnp | grep zabbix #Check whether the Zabbix client is running normally

4. Test whether the communication between the Zabbix client and the Zabbix server is normal

The following code is executed 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 Zabbix client IP address

5. Add monitoring of the Linux host

Open in the browser:

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

## Configuration-Host

Create host

Host name: 192.168.21.128

Group: Linux servers

Endpoint agent interface-IP Address: 192.168.21.128

Status: Monitored

Other options can be defaulted

Switch to template

Select

Select: Template OS Linux

Click to add
