Memory usage

Hi,

I have configure a Linode 1024 according to the instruction in de Linode Library

This Linode now hosts 11 websites, of which 1 drupal and 2 wordpress. None of the are really high-traffic.

The Linode has almost a constant memory-usage of 85%

I see the 2 processes:

Name ▲ User Max # Avg IO Avg CPU Avg Mem

apache2 www-data 12 4 KB/s 0.24% 794 MB

apache2 root 1 12 KB/s 0% 1 MB

Is this normal or should I take some action? I have a number of other sites that should be hosted on this Linode.

hello:

You should be able to follow the guide here:

https://library.linode.com/troubleshoot … networking">https://library.linode.com/troubleshooting/memory-networking

It might also be worth noting that running 11 sites, even if they are medium traffic might be a lot for Apache on that linode. If following that guide does not help, you may want to check out something like Nginx or upgrade your linode's memory.

I'll try Nginx.

Before ordering my Linode, I asked supportteam and they said it would not be a problem at all to run about 30 sites on this Linode!

You can run 1000 or more sites on a Linode 1024, it depends on what they're doing. The number of sites is really irrelevant.

Upvoted.

obs, jebblue

any suggestions for apache settings for let's say 15 wordpress sites with medium traffic then?

Disable keep alives. Set max clients to around 10 and work your way up. Otherwise switch to mpm-worker or nginx to separate php from the web server.

@livefree:

"medium traffic" ?

Yes, from the other side.

(sorry)

What he means is that "medium traffic" is completely subjective. One person's heavy traffic is another's light traffic.
