How To Install Zabbix Server On CentOS 7

By SK Share on Facebook   Tweet on Twitter   

About Zabbix

Zabbix is an enterprise-class open source distributed monitoring solution that can be used to monitor and track performance and availability of network servers, devices and other IT resources. It supports distributed and WEB monitoring, auto-discovery, and more.

Install Zabbix Server

I tested this how-to On CentOS 7 minimal server, although it should work on other RHEL/Scientific Linux 7.x versions.

 

 

For the testing purpose, I will use two machines.

Zabbix Server System:

• Operating system: CentOS 7 64bit server
• IP Address: 192.168.1.150/24
• Hostname: server1.unixmen.local

Zabbix Client System:

• Operating system: CentOS 7 64bit server
• IP Address: 192.168.1.152/24
• Hostname: server2.unixmen.local

First let us start from server side.

 

Prerequisites

Before installing Zabbix, we should have install and configure LAMP stack.

To install and configure LAMP server On CentOS 7, refer the following link.

• Install LAMP Server (Apache, MariaDB, PHP) On CentOS/RHEL/Scientific Linux 7           or         http://www.cnblogs.com/chaochao520/p/5893453.html

Server Side Configuration

Zabbix is not available in the default repositories of CentOS. So, we will add EPEL and Zabbix official repository in order to install Zabbix server.

To install EPEL repository, run the following command:

yum install epel-release

Configure the ZabbixZone package repository and GPG key using command:

rpm --import http://repo.zabbix.com/RPM-GPG-KEY-ZABBIX

rpm -Uv  http://repo.zabbix.com/zabbix/2.4/rhel/7/x86_64/zabbix-release-2.4-1.el7.noarch.rpm

Now, Install Zabbix server and agent using command:

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-java-gateway

Edit file /etc/httpd/conf.d/zabbix:

vi /etc/httpd/conf.d/zabbix.conf

Update your timezone:

php_value date.timezone Asia/Kolkata

Restart the httpd

systemctl restart httpd

Create MySQL database and user for Zabbix

Login to MariaDB prompt with command:

mysql -u root -p

Create a database called ‘zabbixdb’ and database user called ‘zabbixuser’.

Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 10
Server version: 5.5.41-MariaDB MariaDB Server

Copyright (c) 2000, 2014, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> create database zabbixdb character set utf8;
Query OK, 1 row affected (0.05 sec)

MariaDB [(none)]> grant all privileges on zabbixdb.* to 'zabbixuser'@'localhost' identified by 'password';
Query OK, 0 rows affected (0.21 sec)

MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> exit
Bye

Import zabbix templates to Zabbix database

Let us import the following templates. It will ask you the zabbixuser’s password during importing templates.

mysql -u zabbixuser -p zabbixdb < /usr/share/doc/zabbix-server-mysql-2.4.5/create/schema.sql

mysql -u zabbixuser -p zabbixdb < /usr/share/doc/zabbix-server-mysql-2.4.5/create/images.sql

mysql -u zabbixuser -p zabbixdb < /usr/share/doc/zabbix-server-mysql-2.4.5/create/data.sql

Configure Zabbix server

Edit file /etc/zabbix/zabbix_server.conf,

vi /etc/zabbix/zabbix_server.conf

Set the database name, user and password which you’ve created earlier. If the lines are commented out, uncomment and set the correct values.

[...]
DBName=zabbixdb
[...]
DBUser=zabbixuser
[...]
DBPassword=password
[...]

Save and close the file.

Now, we have to set Zabbix server to monitor itself.

To do that, edit file /etc/zabbix/zabbix_agentd.conf,

vi /etc/zabbix/zabbix_agentd.conf

Do the following changes.

[...]

## Line 85 - Specify Zabbix server ##
Server=127.0.0.1

[...]

## Line 126 - Specify Zabbix server ##
ServerActive=127.0.0.1

[...]

## Line 137 - Specify Zabbix server Hostname or IP address ##
Hostname=server1.unixmen.local
[...]

Save and close the file.

Adjust PHP settings

We should adjust phip.ini file as per zabbix recommended settings.

Edit file php.ini,

vi /etc/php.ini

Set the values as shown below. If the lines doesn’t exist, add them.

max_execution_time = 600
max_input_time = 600
memory_limit = 256M
post_max_size = 32M
upload_max_filesize = 16M
date.timezone = Asia/Kolkata

Save and close the file.

Adjust Firewall and SELinux settings               #此處需要在防火牆開啟的狀態中操作，systemctl start firewalld.service 如果防火牆無法開啟，並提示沒有命令，so，yum install -y firewalld   然後再開啟防火牆，並使用開啟端口命令。

Adjust iptables to allow the zabbix ports 10050 and 10051.                    

firewall-cmd --permanent --add-port=10050/tcp,

firewall-cmd --permanent --add-port=10051/tcp

Restart iptables service to take effect the changes.

systemctl restart firewalld

If you use SELinux, run the following command to allow Apache to communicate with Zabbix.

setsebool -P httpd_can_connect_zabbix=1

Allow Zabbix web console for particular IP range (Optional)

Edit file /etc/httpd/conf.d/zabbix.conf,

vi /etc/httpd/conf.d/zabbix.conf

Add the ip range that you want to allow to access zabbix web interface. This is optional. If you set ‘Allow from All’, you can access zabbix’s web console from any network.

In my case, I allowed the 192.168.1.0/24 series.

Alias /zabbix /usr/share/zabbix

<Directory "/usr/share/zabbix">
 Options FollowSymLinks
 AllowOverride None
 Order allow,deny
 Allow from 192.168.1.0/24
</Directory>

Save and close the file. Start/Restart zabbix and httpd services and make them to start automatically on every reboot.

systemctl start zabbix-server

systemctl start zabbix-agent

systemctl restart httpd

systemctl restart mariadb

systemctl enable zabbix-server

systemctl enable zabbix-agent

Configure Zabbix via Web console

We have completed the installation and configuration part. Now let us configure the zabbix web console.

Navigate tohttp://ip-address/zabbix or http://domain-name/zabbix.

Click Next.

The installer will check for necessary prerequisites. If everything seems OK, click Next to continue, else go back and install the necessary packages.

Enter the zabbix database name, database user and password and click Test connection. If you entered the correct values, it will show a message that says: OK.

Click Next to continue.

Enter your server name and Click Next:

Check the pre-installation summary, if everything good, click Next to continue or click Previous to change the parameters.

Congratulations! You’ve have successfully completed the installation. Click Finish to complete the installation.

Now you’ll be redirected to the zabbix web console page. Enter the username and password.

The default username/password is admin/zabbix.

This is how the admin dashboard looks:

Activate Zabbix server

Initially, the zabbix server is deactivated from being monitored.

To activate it, go to Configuration -> Hosts. Select the host (zabbix server) and chooseActivate selected from the drop-down box and click Go.

Now, you should see your Zabbix server is being monitored.

Check Zabbix server Statistics

After a few seconds, click on the Monitoring tab on the top menu bar and select “Latest data”.

You’ll see the zabbix server’s details:

To view the screens, go to Monitoring -> Screens from the Zabbix’s dashboard.

That’s it. We’re done in the server side. Let us go to client side configuration.

Client Side Configuration

Let us install zabbix agent on our client systems.

To install zabbix agent packages on Fedora/RHEL clients, enter the following commands in Terminal:

rpm --import http://repo.zabbix.com/RPM-GPG-KEY-ZABBIX

rpm -Uv  http://repo.zabbix.com/zabbix/2.4/rhel/7/x86_64/zabbix-release-2.4-1.el7.noarch.rpm

yum install zabbix-agent -y

On Ubuntu/Debian clients, run:

sudo apt-get install zabbix-agent

Configure Clients

Next edit file /etc/zabbix/zabbix_agentd.conf,

sudo vi /etc/zabbix/zabbix_agentd.conf

Add the server ip address and client hostname.

[...]
## Specify Zabbix's server IP address ##
Server=192.168.1.150
[...]
##Specify Zabbix's server IP address ##
ServerActive=192.168.1.150
## Specify client system hostname ##
Hostname=server2.unixmen.local
[...]

Where,

• 192.168.1.150 – My Zabbix server IP address
• server2 – My Zabbix client’s hostname

Now restart zabbix-agent service with command:

In Ubuntu/Debian:

sudo service zabbix-agent start

In CentOS 7:

systemctl start zabbix-agent

systemctl enable zabbix-agent

Add Monitoring hosts

Go to your zabbix server dashboard.

To add a monitoring target, navigate to Configuration -> Hosts. Click on Create Host on the right side.

Enter Hostname, select Groups and IP address in the Host section as shown below.

Next, In the Templates section select your Template.

In my case, I selected Linux Template and SSH template. After selecting your Template choice click Select button in the bottom.

In the next window, click Add and click Update buttons.

Now, you will see that the new host has been added to the Monitoring list.

That’s it.

If there is any problem in the Client system, you can view them in the main Dashboard of your Zabbix’s server.

Go to Monitoring -> Latest data to check the details of client.

You can view the list of all warnings and information in Monitoring -> Triggers location.

Conclusion

In this tutorial, we have covered only installation part and basic configuration of Zabbix. To learn more about Zabbix, explore all the options in the Zabbix’s dashboard one by one and set up a best monitoring solution that suits your requirement.
