Moodle Database won't connect

Question

I have installed Moodle 2.8 on CentOS 7 .
I face a problem.

Error: Database connection failed

It is possible that the database is overloaded or otherwise not running properly.
The site administrator should also check that the database details have been correctly specified in config.php

and my Config.php is as follow:

CFG->dbtype    = 'mariadb'                    
CFG->dblibrary = 'native'                   
CFG->dbhost    = '192.0.0.0'     
CFG->dbname    = 'moodle'            
CFG->dbuser    = 'moodle'                
CFG->dbpass    = 'password'      

and my data path is: ver/moodledata and Document root is : var/www/html/moodle

How can I solve this problem. Please help me.I am new in moodle.

Answer 1

Okay so looks like an issue with the database rather than moodle.

This might have the answer - ERROR 1130 (HY000): Host '' is not allowed to connect to this MySQL server

Try that then try the command line again

mysql -u moodle -p -h 192.0.0.0 moodle

If the command line works then Moodle should work.
