Problems with MySQL

Please doublecheck all passwords. Mostly people setup the system with a wrong password. In this case it is the easiest way to re-setup the system.

Check the database connect

To check the database connect use '~otrs/bin/CheckDB.pl' . Is the output "It looks Ok!", you don't have problems with MySQL. If not, read the error message.

Access denied for user: 'otrs@localhost'

Check the password in Kernel/Config.pm for the database user. If you don't know the database password for the database otrs user, set it new:
shell> mysql -u root -p
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 37 to server version: 3.23.48-log

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> GRANT ALL PRIVILEGES ON otrs.* TO otrs@localhost IDENTIFIED BY "yourpw" WITH GRANT OPTION;
mysql> 
and change it in Kernel/Config.pm.
