Web Hosting Talk : Web Hosting Main Forums : Dedicated Server : 2 Servers, two network cards, one ethernet cable

[arn]

Hey...

Quick question...

Let's say I've got two servers (a and b), each with 2 network cards, both in the same hosting location.

One card in each connects to the internet, and the other cards connect to each other.

I want one server (Server B) to act as the mysql server for the other server (Server A).

Now... when writing code/scripts on Server A -- how do I ensure that I'm passing data through the direct network card? If I use Server B's IP address, is it smart enough to route directly via the direct ethernet cable... or will it go through the router --- which would still be fast, since it's all local anyhow - but would make the second network card unncesssry.

Each server would have 2 ip addresses. One for each network card. In your script, if you connect to the ip which is bound to the network card which is connected locally, it will go throught the local network.

just in case you can use route and tell it that its on the other network card . Since the two of them are directly connected why dont you give the secondary ethernet card on both of them a 10.*.*.*.* ip address and then eneter the route information and presto it should work :-)

Yes - just make sure you've used private IP addresses for the "internal" connection (such as 192.168.0.[1,2]). That way even if your script messes up and it's somehow sending the data over the Internet you'll know right away because those addresses won't be routable.

Why connect the MySQL server directly to the Internet anyway?
