Frontend installation prerequisites

Zabbix frontend requires additional packages not available in basic installation. You need to enable repository of optional rpms in the system you will run Zabbix frontend on:

ll /etc/yum.repos.d/
vi public-yum-ol7.repo

[root@aot-zbx02 yum.repos.d]# vi public-yum-ol7.repo
[ol7_optional_latest]
name=Oracle Linux $releasever Optional Latest ($basearch)
baseurl=https://yum.oracle.com/repo/OracleLinux/OL7/optional/latest/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

安裝MariaDB

yum repolist
yum list mariadb*
yum install mariadb*

安裝 php, httpd

yum install nmap httpd policycoreutils-python net-snmp net-snmp-utils php-bcmath php-mbstring php-xml curl curl-devel net-snmp-devel perl-DBI
yum install php php-gd php-ldap php-mysql php-odbc php-pdo php-pear php-pecl-memcache php-soap php-xmlrpc

Start MariaDB

systemctl start mariadb
systemctl enable mariadb
systemctl status mariadb

修改資料庫root密碼 (選用)

mysqladmin -uroot password 1234qwer

Adding Zabbix repository

rpm -Uvh http://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-2.el7.noarch.rpm

Install Zabbix Server, Zabbix Forntend and Zabbix Agent

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

Creating database

MySQL - Character set utf8 and utf8_bin collation is required for Zabbix server to work properly with MySQL database.

mysql -uroot
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';

Importing data

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -pzabbix zabbix

mysql -uzabbix -pzabbix zabbix

mysql> SELECT
table_name AS `Table`,
round(((data_length + index_length) / 1024 / 1024), 2) `Size in MB`
FROM information_schema.TABLES
WHERE table_schema = "zabbix";

Configure database for Zabbix server

vi /etc/zabbix/zabbix_server.conf

LogFileSize=10
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

Starting Zabbix server process

systemctl start zabbix-server
systemctl enable zabbix-server
systemctl status zabbix-server

Zabbix frontend configuration

For RHEL 7 and later the Apache configuration file for Zabbix frontend is located in /etc/httpd/conf.d/zabbix.conf.

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

        # php_value date.timezone Europe/Riga
        php_value date.timezone Asia/Taipei


systemctl start httpd
systemctl enable httpd

Frontend installation steps 

Allow you to access your newly installed Zabbix.
Note that a Zabbix proxy does not have a frontend; it communicates with Zabbix server only.

http://zabbix-frontend-hostname/zabbix

Enter password of zabbix

Configure and start Zabbix Agent

vi /etc/zabbix/zabbix_agentd.conf
LogFileSize=10
Server=127.0.0.1
ServerActive=127.0.0.1
Hostname=Zabbix server


systemctl start zabbix-agent
systemctl status zabbix-agent
systemctl enable zabbix-agent

All jobs are completed 

Zabbix frontend is available at http://zabbix-frontend-hostname/zabbix in the browser. Default username/password is Admin/zabbix.
