Step 1 – Install Apache2\/httpd<\/h2>\n
In this guide, we will run Zabbix under the Apache web server. The web server packages can be installed from the default CentOS 7 repository.<\/p>\n
Install Apache\/httpd using the yum command below.<\/p>\n
sudo yum -y install httpd<\/p>\n
After the installation is complete, start the service and enable it to launch every time at system boot.<\/p>\n
systemctl start httpd
systemctl enable httpd<\/p>\nThe Apache\/httpd web server has been installed on the system – check it using the netstat command.<\/p>\n
netstat -plntu<\/p>\n
And you will get the default HTTP port 80 in the LISTEN state.<\/p>\n

<\/a><\/p>\nStep 2 – Install and Configure PHP 7.2 on CentOS 7<\/h2>\n
In this step, we will install PHP 7 from a third-party repository – we will install PHP 7.2 from the ‘webtatic’ repository.<\/p>\n
Before installing PHP 7 with all extensions needed, add the webtatic and the EPEL repository to the system.<\/p>\n
Run commands below.<\/p>\n
yum -y install epel-release
sudo rpm -Uvh https:\/\/mirror.webtatic.com\/yum\/el7\/webtatic-release.rpm<\/p>\nNow install PHP 7.2 packages from the webtatic repository using yum.<\/p>\n
yum -y install mod_php72w php72w-cli php72w-common php72w-devel php72w-pear php72w-gd php72w-mbstring php72w-mysql php72w-xml php72w-bcmath<\/p>\n
And after the installation is complete, we need to edit the default ‘php.ini’ file using the vim editor.<\/p>\n
vim \/etc\/php.ini<\/p>\n
Change the values of the configuration as shown below.<\/p>\n
max_execution_time = 600
Save and exit.<\/p>\n
Now restart the httpd service.<\/p>\n
systemctl restart httpd<\/p>\n
The PHP 7 installation and configuration for Zabbix has been completed.<\/p>\n
Step 3 – Install and Configure MariaDB<\/h2>\n
Zabbix offers support for many databases for the installation, including MySQL, PostgreSQL, SQLite, and Oracle database. For this guide, we will be using MariaDB as the database for our Zabbix installation.<\/p>\n
Install mariadb-server using yum command below.<\/p>\n
sudo yum -y install mariadb-server<\/p>\n
After the installation is complete, start the service and enable it to launch everytime at system boot.<\/p>\n
systemctl start mariadb
systemctl enable mariadb<\/p>\nNow run the command below to configure MariaDB root password.<\/p>\n
mysql_secure_installation<\/p>\n
Type your root password and press Enter.<\/p>\n
![\"Install](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-1.png\" "\\"\\"")
<\/a><\/p>\nMariaDB database has been installed, and the root password has been configured.<\/p>\n
Next, we need to create a new database for our Zabbix installation. We will create a new database and user named ‘zabbix<\/strong>‘ with password ‘[email\u00a0protected]<\/a><\/strong>‘.<\/p>\n
Login to the MySQL shell.<\/p>\n
mysql -u root -p<\/p>\n
And run the following MySQL queries on the shell.<\/p>\n
create database zabbix;
grant all privileges on zabbix.* to [email\u00a0protected]<\/a>‘localhost’ identified by ‘[email\u00a0protected]<\/a>‘;
grant all privileges on zabbix.* to [email\u00a0protected]<\/a>‘%’ identified by ‘[email\u00a0protected]<\/a>‘;
flush privileges;<\/p>\nNew database for Zabbix installation has been created.<\/p>\n
![\"Create](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-2.png\" "\\"\\"")
<\/a><\/p>\nStep 4 – Install and Configure Zabbix 3.4<\/h2>\n
In this step, we will install and configure Zabbix. We will install Zabbix from the official repository, then configure Zabbix-server and Zabbix-agent.<\/p>\n
– Install Zabbix Packages
<\/strong><\/p>\nAdd the Zabbix repository to the CentOS 7 system.<\/p>\n
yum -y install http:\/\/repo.zabbix.com\/zabbix\/3.4\/rhel\/7\/x86_64\/zabbix-release-3.4-1.el7.centos.noarch.rpm<\/p>\n
Now install Zabbix using the yum command below.<\/p>\n
yum -y install zabbix-get zabbix-server-mysql zabbix-web-mysql zabbix-agent<\/p>\n
Wait for the Zabbix packages installation.<\/p>\n
![\"Install](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-3.png\" "\\"\\"")
<\/a><\/p>\n– Import Database Sample<\/strong><\/p>\n
Import the Zabbix database sample to our ‘zabbix’ database. Go to the Zabbix documentation directory and extract the Zabbix sql file.<\/p>\n
cd \/usr\/share\/doc\/zabbix-server-mysql-3.4.6\/
gunzip create.sql.gz<\/p>\nNow import the database sample to our ‘zabbix’ database.<\/p>\n
mysql -u root -p zabbix < create.sql<\/p>\n
Type your root password and make sure there is no error.<\/p>\n
![\"Import](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-4.png\" "\\"\\"")
<\/a><\/p>\n– Configure Zabbix Server<\/strong><\/p>\n
Zabbix-server is the central process of the Zabbix software system. We will configure the Zabbix-server by editing the configuration file using the\u00a0vim<\/a> editor.<\/p>\n
Run the following command.<\/p>\n
vim \/etc\/zabbix\/zabbix_server.conf<\/p>\n
On the database line configuration, type the configuration as below and change the ‘DBPassword’ value with your own database password.<\/p>\n
DBHost=localhost
[email\u00a0protected]<\/a><\/p>\nSave and exit.<\/p>\n
Now start the Zabbix-server service and enable it to launch everytime at system boot.<\/p>\n
systemctl start zabbix-server
systemctl enable zabbix-server<\/p>\nZabbix-server is running on the CentOS 7 system – check it using the command below.<\/p>\n
systemctl status zabbix-server<\/p>\n
And you will get the result as shown below.<\/p>\n
![\"Configure](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-5.png\" "\\"\\"")
<\/a><\/p>\n– Configure Zabbix Agent<\/strong><\/p>\n
Zabbix-agent must be installed on the target monitoring system. The agent will gather all information of the server and reports data to the Zabbix-server.<\/p>\n
Edit the Zabbix-agent configuration file using vim.<\/p>\n
vim \/etc\/zabbix\/zabbix_agentd.conf<\/p>\n
Change following lines with your own info:<\/p>\n
Server=127.0.0.1
Save and exit.<\/p>\n
Now start the zabbix-agent and enable it to launch everytime at system boot.<\/p>\n
systemctl start zabbix-agent
systemctl enable zabbix-agent<\/p>\nZabbix-agent is running on the system – check it using the following command.<\/p>\n
systemctl status zabbix-agent<\/p>\n
And you will get the result as shown below.<\/p>\n
![\"Configure](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-6.png\" "\\"\\"")
<\/a><\/p>\nStep 5 –\u00a0 Configure Firewalld<\/h2>\n
In this step, we will open the HTTP and https port for Zabbix admin web UI, and will also add an additional port for Zabbix-server and Zabbix-agent.<\/p>\n
If you do not have firewalld on your system, install it using the following command.<\/p>\n
yum -y install firewalld<\/p>\n
Start the firewalld service and enable it to launch everytime at system boot.<\/p>\n
systemctl start firewalld
systemctl enable firewalld<\/p>\nNow we will open the HTTP and https port, and the port that will be used by the Zabbix-server and Zabbix agent (port 10051 and 10050).<\/p>\n
Run the following firewall-cmd commands.<\/p>\n
firewall-cmd –add-service={http,https} –permanent
firewall-cmd –add-port={10051\/tcp,10050\/tcp} –permanent<\/p>\nNow reload the firewalld configuration and check the port.<\/p>\n
firewall-cmd –reload
firewall-cmd –list-all<\/p>\n![\"Configure](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-7.png\" "\\"\\"")
<\/a><\/p>\nFirewalld configuration for Zabbix installation has been completed.<\/p>\n
Step 6 – Zabbix Initial Setup<\/h2>\n
Before going any further, we will restart all of our services using the systemctl commands below.<\/p>\n
systemctl restart zabbix-server
systemctl restart zabbix-agent
systemctl restart httpd<\/p>\nNow open your web browser, and type your server IP address.<\/p>\n
http:\/\/192.168.33.10\/zabbix\/<\/a><\/p>\n
And you will be redirected to the Zabbix welcome message.<\/p>\n
![\"Zabbix](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-8.png\" "\\"\\"")
<\/a><\/p>\nClick the ‘Next Step<\/strong>‘ button.<\/p>\n
Now, Zabbix will check all system requirements for its installation. Make sure there is no error.<\/p>\n
![\"Check](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-9.png\" "\\"\\"")
<\/a><\/p>\nThen click the ‘Next step<\/strong>‘ button again.<\/p>\n
For the database info, type all your database setup.<\/p>\n
![\"Configure](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-10.png\" "\\"\\"")
<\/a><\/p>\nAnd click the ‘Next step<\/strong>‘ button.<\/p>\n
Now comes the Zabbix server details configuration. On the ‘Host’ field, type your own server IP address, and change the name with your own domain name or hostname.<\/p>\n
![\"Server](\"https:\/\/afaghhosting.net\/blog\/wp-content\/uploads\/2018\/04\/how-to-install-and-configure-zabbix-on-centos-7-11.png\" "\\"\\"")
<\/a><\/p>\nClick the ‘Next step<\/strong>‘ button again.<\/p>\n
Make sure all of those configurations are correct, then click the next button to install Zabbix.<\/p>\n
