Apache / Re: server reached MaxClients setting, consider raising the MaxClients setting

« on: June 03, 2023, 09:29:10 AM »

I got into this part. I hope my problem will be fixed.
Do I need to edit anywhere other than here?

<IfModule mpm_event_module>
StartServers              3
MinSpareThreads           63
MaxSpareThreads           127
ThreadsPerChild           382
ThreadLimit               382
MaxRequestWorkers         3056
ServerLimit               3066
MaxConnectionsPerChild    4000
</IfModule>

Put all settings offered by apache_mpm_calculator into the appropriate section of:

Code: [Select]

/usr/local/apache/conf/extra/httpd-mpm.confPlease don't forget to make backup of the file before you modify it in order to undo the changes if something goes wrong.

Which option should I enter the values in the calculation?

StartServers                    3
MinSpareThreads              63
MaxSpareThreads             127
ThreadsPerChild               382
ThreadLimit                     382
MaxRequestWorkers         3056
ServerLimit                      3066
MaxConnectionsPerChild    4000

You just need to change the value in the appropriate section (prefork, worker, event) of:

Code: [Select]

/usr/local/apache/conf/extra/httpd-mpm.confand then restart Apache.

The value depends on available (free memory). Don't set the value too high. I recommend you to following:

1. Check how much free memory you have;
2. Find the most memory expensive http/apache process;
3. Divide free memory by the RAM usage of the most expensive http/apache process;
4. Divide the result by two.

Don't forget other services eat RAM too

I recommend you to check the following guide:
https://www.woktron.com/secure/knowledgebase/133/How-to-optimize-Apache-performance.html

Also, you can use:

Code: [Select]

/scripts/apache_mpm_calculatorto get values recommended by CWP.

What values can we set this file with?
Do I need to make settings elsewhere after changing this file?

/usr/local/apache/conf/extra/httpd-mpm.conf
