Installing the WebGUI interface

The WebGUI interface will be done once more using the RPMs.

To install the web interface, you need to run the following command:

$ yum install zabbix-web-mysql

Yum will take care to resolve all the dependencies. Once you're done, the process of this component is quite easy: we need to open a web browser, point at the following URL: http://your-web-server/zabbix, and follow the instructions.

On the standard Red Hat system, you simply need to change these parameters on your /etc/php.ini file:

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

Also, set your time zone on the same file (for example, php_value date.timezone Europe/Rome).

Now, it's time to start up Apache, but before this, we need to check whether we have SELinux enabled and on which mode? To check your SELinux status, you can run:

# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   permissive
Mode from config file:          permissive
Policy version:                 24
Policy from config file:        targeted

Now, you need to check whether you have the httpd daemon enabled to use the network with the following command:

# getsebool httpd_can_network_connect
httpd_can_network_connect --> off

Most likely, you will have the same kind of result, then all we need to do is enable the httpd_can_network_connect option using the next command with –P to preserve the value after a reboot:

# setsebool –P httpd_can_network_connect on
# getsebool httpd_can_network_connect
httpd_can_network_connect --> on 

Now, all that we still have to do is enable the httpd daemon and start our httpd server:

# service httpd start
Starting httpd:                              [  OK  ]

Next, enable the httpd server as a service:

# chkconfig httpd on

We can check the change done with the next command:

# chkconfig --list httpd
httpd       0:off   1:off   2:on    3:on    4:on    5:on    6:off

Once you've done this, you only need to follow the wizard, and in a few clicks, you will have your web interface ready to start up.

Tip

If you know that the load against the web server will be high, due to a high number of accounts that will access it, probably, it's better to consider using Nginx.

Now, you can finally start your Zabbix server and the first entry in the /var/log/zabbix/zabbix_server.log file will look something like the following code:

Next, you can start to implement and acquire all the items critical for your network.
