I have a dedicated server that has three websites, two of which use a MySQL database. The entire server will probably only receive about 50 visitors per day and doesn't serve a lot of images. It is running Red Hat 7.2 and has a 500 MHz processor, 5 GB hard drive, and 32 MBs of RAM.
The server normally uses about 23 MBs and has 5 MBs free. Is this OK to get by on? I'm paying next to nothing for the server and I primarily got it to learn how to administer a server. For some reason, my web host said that I can't add more RAM to the server because it was a special (I'm on a 12 month contract with 11 months to go). From looking at the info below can somebody tell me if I really need more RAM or is it OK the way it is?
Even on servers with like 1gb ram i find that it rarely has much in the "free" section of that but there is quite a lot on buff and cached, so I think you can get by on the 32mbs ram with your current usage.
That is good to hear. It seems like there's an awful lot of processes running on my server when it doesn't really have any visitors to it besides myself. Can somebody tell me if I can eliminate some of them permantly?
Type "free" at the command line and look at the second line how much memory is really free. Linux does not work like Windows, it uses whatever memory is available. Your system shows that you have 2604KB buffered and 6956KB cached. This is basicly also free memory.
I wouldn't worry as long as those load averages stay as low as they are now.
