Please help give me a clue here
![]() I have a dedicated server with cpanel and one of the options is DNS Clustering. If I add another dedicated server what does this do for me? Is there a way to have one as a dedicated mysql server and the other for mail and apache? Also, and this is basic, why when everything from top to vb shows the load there are 3 numbers? ie. 4.01, 3.51, 1.56 ? Thanks in advance, -Jason |

1st = 1minute
2nd = 5minute 3rd = 15 minute load average. You don't need load balancing if you just got 1 webserver and 1 DB server. Just change config.php of vBulletin to point to the DB server, make sure that it does accept non-local connections for the account and you're settled. Both servers should be cross-connected via seperate NICs. Make sure that you do use the "internal" IP of the DB server in config.php |

So if I buy a second dedicated server and set up the DNS clustering I can do this? So would it be it be something other than 'localhost' I presume in the config.php? I am still pretty new at all of this so I apologize if you need to dumb it down to me ![]() Thanks, -Jason |

As already said, you don't need "DNS clustering" for that purpose.
This would only be needed if you got several web-servers that should be accessible as one host (eg. www.yourdomain.com) but where the requests should be balanced (round robin) on them. If you got a separate DB server, place it's hostname or IP in config.php and you're done. |

DNS clustering has nothing to do with server clustering per se.

Just remember to have them connected via a cross-over like Kirby said. If you have requests to mySQL going back and forth across the net its not only slow but un-secure and will eat up alot of bandwidth.

From my thread here: http://www.vbulletin.com/forum/showt...921#post810921 We have implemented full load balancing on our forums, which is working great. However, now all IP logging shows the virtual IP of the load balancer, and not the user themself. The load balancer passes 'X-Cluster-Client-Ip' with the original client IP address (at least for clear http requests; https and other protocols, not so much). In this http://forums.servermatrix.com/viewtopic.php?t=9828 thread, there is a suggestion on how to fix this issue for your apache logs. I'm not sure how to fix it in the VBulliten case. The problem isn't in our logs. The problem is in the vb admincp - when you click to view a users ip, they are all showing as the LB's ip, not the user's actual ip. Sounds liek we have to hack vb to read the xforwarded by? Yes you would have to hack the VB code to get that functionality Thoughts? |
