Limit Apache to 1 request per process
I have a few long running processes on apache and when the server gets a bit of a load they all seem to couple into开发者_StackOverflow 3-4 processes. I've tried setting the MaxRequestsPerChild to 1 and that works, but spawning new processes all the time is expensive. So is there a way to limit 1 request per process / thread, without constantly destroying it.
Here is my current configuration:
<IfModule prefork.c>
StartServers 25
MinSpareServers 50
MaxSpareServers 50
ServerLimit 512
MaxClients 50
MaxRequestsPerChild 10
</IfModule>
<IfModule worker.c>
StartServers 25
MaxClients 50
MinSpareThreads 50
MaxSpareThreads 125
ThreadsPerChild 50
MaxRequestsPerChild 10
</IfModule>
You want to disable 'KeepAlive':
KeepAlive off
That disables persistent connections. See http://httpd.apache.org/docs/2.0/mod/core.html#KeepAlive
ThreadsPerChild control the number of requests per process. So here is my resulting config:
<IfModule prefork.c>
StartServers 100
MinSpareServers 150
MaxSpareServers 150
ServerLimit 512
MaxClients 150
MaxRequestsPerChild 100
</IfModule>
<IfModule worker.c>
StartServers 100
MaxClients 150
MinSpareThreads 150
MaxSpareThreads 150
ThreadsPerChild 1
MaxRequestsPerChild 100
</IfModule>
