I have two servers crossconnected. One server is a Http Server, the other a Mysqlserver.
Both servers have the same hardware and installed systems if this necessary to know.
System: CentOs5 2.6.18-53.1.21
### Mysqlserver ###
Mysqlversion: 5.0.22-2.2
### Httpserver ###
Apache: 2.2.3-11
PHP: 5.1.6-15
Now to my problem, which let me flipped out and I wished to fly to Dallas and give the both computer a kick, so they whished, that they never be installed
I have a vBulletin forum - before I had a single server and the forum works - and it fails with the following error if I set the connection data to the Mysqlserver:
Error description: mysqli_real_connect() [function.mysqli-real-connect]: (HY000/2003): Can't connect to MySQL server on 'x.x.x.xl' (13) /var/www/html/dm/includes/class_core.php on line 1040
x.x.x.x is the IP address of the MySQL server - tried hostname, 10.0.0.2 - don't work too. I am trying to install vBulletin on a different server than the MySQL database.
But if I run the MySQL command line on the Httpserver I can connect to the database server. So what could be the problem?
