httpd process always 256

Question

I am using Amazon EC2 and apache 2.4, when I conduct stress tests, the httpd max processes is always 256

[ec2-user@xxxxxx]ps aux | grep httpd
259

httpd conf

<IfModule mpm_prefork_module>
 StartServers       10
 MinSpareServers    10
 MaxSpareServers   64
 ServerLimit      1600
 MaxClients       1600
 MaxRequestsPerChild 3000
 </IfModule>

MPM conf

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

httpd -V

Server MPM:     prefork
  threaded:     no
    forked:     yes (variable process count)

maybe I am missing something?

Make sure that you are using MPM configuration after LoadModule mpm_prefork_module modules/mod_mpm_prefork.so line. Means remove MPM configuration form httpd.conf file and add in 00-mpm.conf file.


LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
<IfModule mpm_prefork_module>
 StartServers       10
 MinSpareServers    10
 MaxSpareServers   64
 ServerLimit      1600
 MaxClients       1600
 MaxRequestsPerChild 3000
 </IfModule>

Server MPM: prefork; threaded: no; forked: yes (variable process count) – Leon Lai Jun 05 '20 at 03:12
still not work, I check that apache is running as prefork。 but after increased ServerLimit and MaxClients, still 256. – Leon Lai Jun 05 '20 at 05:23
