Server monitoring with Icinga 2 and Icingaweb 2 on CentOS 7 - Page 2

5. Install icingaweb2

Before installing icingaweb2 be sure to open port 80 on your firewall.

Install icingaweb2:

yum -y install icingaweb2

Install icingacli. We will need it later to create a setup token for the webbased part of the installation.

yum -y install icingacli

We will now check if the group icingaweb2 exists and if apache is a member of that group:

cat /etc/group | grep icingaweb2

Output:

[root@icinga2 tmp]# cat /etc/group | grep icingaweb2
icingaweb2:x:990:apache

icinga2 will report a warning for the http service because there is no index.hml file at the webroot.
To prevent this we will create an empty one:

touch /var/www/html/index.html

chown apache /var/www/html/index.html

We will now create the setup token for the webbased part of the installation.

icingacli setup config directory --group icingaweb2

Output:

[root@icinga2 tmp]# icingacli setup config directory --group icingaweb2
Successfully created configuration directory /etc/icingaweb2

icingacli setup token create

Output:

[root@icinga2 tmp]# icingacli setup token create
The newly generated setup token is: 1826XXXXXXXXXXXX

Write down or copy the setup token.

Restart apache.

systemctl restart httpd

Web based part of the installation

Open a browser and go to http://192.168.250.100/icingaweb2/setup
