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
