Dears,

I did the installation of NAGIOSXI following all the steps in the installation guide. I'm using an installation of 32-bit CentOS 5.5 with kernel 2.6.18-194.11.4.el5PAE.

The database MySQL and Postgres are running normally created successfully as can be seen below:

Postgres

Bear with me if you've tried this already, but try restarting both postgresql and mysql and see if that fixes it.

service mysqld restart
service postgresql restart

MySQL is running, but it does not have the relevant data in it. The import databases step of the installation appears to have failed with MySQL while succeeding with postgres. Most commonly this is the result of having a password set for the MySQL root user before running the installation, which expects that to be blank.
