[LINUX] The story of building Zabbix 4.4


I wanted to touch Zabbix, so I built it with GCP and at the time of building (February 2020) with the latest version of Zabbix 4.4.


First, create an instance for Zabbix server. I created it as follows. Regarding machine specifications, the required specifications will change depending on the number of monitoring targets and the number of monitoring items to be registered. This time it's a test, so it's appropriate.

item Contents
Instance name zabbix-server
region us-central1
zone us-central1-f
Machine type n1-standard-2 (vCPU x 2, memory 7.5 GB)
Boot disk CentOS 7
IP address Create a static IP address

The environment used is as follows.

item Contents
OS CentOS 7.7
Middleware Apache
Zabbix server 4.4
Zabbix agent 4.4


** List of sites that I referred to **

-Zabbix Official Documentation --Qiita's Zabbix related articles

1. Installation of required packages

Add Zabbix repository. If a new version is released, please check from the official repository below.

Zabbix Official Repository

Install the repository configuration package.

$ rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

Next, install the necessary packages as a prerequisite. For php, use group install to install related packages as well.

#Installation of required packages
$ yum install httpd

$ yum install mariadb mariadb-server

$ yum groupinstall php

Then install the required packages on Zabbix server. You will be asked yes / no several times, but please proceed with y. If it is troublesome, add -y to the issue command and execute it, all will be executed with y.

$ yum install zabbix-web-mysql zabbix-web-japanese zabbix-server-mysql

2. Set various things

First, set up Zabbix server.

#Edit configuration file-Uncomment the line and set the DB password
$ vi /etc/zabbix/zabbix_server.conf
The following changes
# DBPassword=
DBPassword=xxxxxxxxxx <---Enter any password here

Next, set the DB.

#Enable auto-start setting
$ systemctl enable mariadb
#Service startup
$ systemctl start mariadb

#Perform initial DB settings
# yes/You will be asked no several times, but all[y]Please proceed with. Password is zabbix_server.I made it the same as the one set in conf.
$ mysql_secure_installation

#Login to DB
$ mysql -u root -p <password>

#Database zabbix character set utf8 collat e utf8_Create a bin.
MariaDB [(none)]> CREATE DATABASE zabbix character set utf8 collate utf8_bin;

MariaDB [(none)]> CREATE USER zabbix@localhost IDENTIFIED BY '<password>';

MariaDB [(none)]> GRANT ALL ON zabbix.* TO zabbix@localhost;

MariaDB [(none)]> quit

Load the schema file for Zabbix into the database.

$ zcat /usr/share/doc/zabbix-server-mysql-4.4.*/create.sql.gz | mysql -u zabbix -p zabbix
Enter password:← Enter the password of DB user zabbix

Disable SELinux settings and restart the OS.

$ vi /etc/sysconfig/selinux

$ reboot

Firewall settings (zabbix server side)

$ firewall-cmd --add-port=10051/tcp --zone=public --permanent
$ firewall-cmd --add-service=http --zone=public --permanent
$ firewall-cmd --reload

Set Apache's automatic start and start the service.

$ systemctl enable httpd
$ systemctl start httpd

Roughly at least the settings on the Zabbix server side are over.

3. Monitoring target settings

From here, the settings will be made on the monitored side.

Installation of zabbix-agent

#Add Zabbix repository
$ rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm

$ yum install zabbix-agent

Edit configuration file

$ vi /etc/zabbix/zabbix_agentd.conf
#Enable remote command monitoring,Uncomment and change the value to 1
#The following changes
# EnableRemoteCommands=0

#Server IP address that allows monitoring
#Change to Zabbix server IP address

#IP address of the server to which the active check monitoring data is sent
#Change to Zabbix server IP address

#Note that it is not the host name on the OS, but the host name on Zabbix monitoring settings.
Hostname=Zabbix server

Set automatic start of zabbix-agent and start service.

$ systemctl enable zabbix-agent

$ systemctl start zabbix-agent

Firewall settings (monitored server side)

$ firewall-cmd --add-port=10050/tcp --zone=public --permanent

$ firewall-cmd --add-source=<IP address of Zabbix server here> --zone=public --permanent

$ firewall-cmd --reload

Roughly at least the settings on Zabbix-agent side are completed.

Let's take a look at the management screen!


Follow the instructions on the screen to proceed with the initial settings スクリーンショット 2020-02-04 16.17.01.jpg

Confirm that the dashboard is displayed, and the initial setting is completed. スクリーンショット 2020-07-03 22.03.38(2).jpg

Up to this point, the settings until monitoring can be taken are complete. Thank you for your hard work.

As an aside, I personally recommend a dark theme that is easy on the eyes. It can be set from the following. スクリーンショット 2020-07-03 22.10.01(2).jpg

The dashboard looks like this スクリーンショット 2020-07-03 22.10.36(2).jpg


After that, I tried to monitor the previously built Minecraft server and discord-bot server, Zabbix is good, I really like it ^^

I wanted to try various things and study so that I could use Zabbix more. See you again!
