Zabbix Server Installation

CentOS 7

rpm -ivh http://repo.zabbix.com/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm
yum install zabbix-server-mysql zabbix-web-mysql
yum install mariadb-server mariadb

The following commands are for database creation, but they are not specific. Needs work

shell> mysql -uroot -p<password>
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '<password>';
mysql> flush privileges;
mysql> quit;
cd /usr/share/doc/zabbix-server-mysql-3.0.4/create
shell>  cat create.sql | mysql -hxxx.xxx.xxx.xxx -uzabbix -p zabbix

Some packages might combine those three SQL files in one, so you will only have create.sql.gz. You can import it directly as "zcat create.sql.gz | mysql zabbix". If you want to see the SQL file, you can extract it with 'tar -xvf create.sql.gz' in a single step.

Edit the Zabbix Server configuration file

# vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

Start the zabbix server

systemctl start zabbix-server

Edit the php configuration file to use the correct time zone /etc/httpd/conf.d/zabbix.conf

php_value max_execution_time 300
php_value memory_limit 128M
php_value post_max_size 16M
php_value upload_max_filesize 2M
php_value max_input_time 300
php_value date.timezone America/New_York

Start http

systemctl start httpd 

Configure SELinux to allow the above services network access

setsebool -P zabbix_can_network=true
setsebool -P httpd_can_network_connect=true

Enable all service

systemctl enable mariadb
systemctl enable httpd
systemctl enable zabbix-server

At this point you should be able to access the web interface by going to <IP of host>/zabbix. User/password is admin/zabbix.

If everything is working reboot the server, and test again.

Troubleshooting

• Reset the password: use zabbix; update zabbix.users set passwd=md5('newpass') where alias='Admin';
