hello all (newbie here)
i have about eight /usr/sbin/httpd processes running. each will start up multiple /usr/bin/php-cgi processes.
what is the best way to limit the number of /usr/bin/php-cgi processes that can start up?
i did try playing with the following values but wanted to get some expert opinions first:
| Code: | <IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
ServerLimit 256
MaxClients 40 ## changed from 256
MaxRequestsPerChild 4000
</IfModule>
<IfModule worker.c>
StartServers 4
MaxClients 40 ## changed from 256
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule> |
as always, any help or suggestions are greatly appreciated. |

good question, and one i am not sure how to answer.
i am using webmin/virtualmin, and i have selected the second option: CGI wrapper:
| Quote: | PHP script execution mode:
. . Apache mod_php (run as Apache's user)
. . CGI wrapper (run as virtual server owner)
. . FCGId (run as virtual server owner)
|
here is an example of what is in my http.conf file:
| Code: | <VirtualHost 199.231.184.26:80>
SuexecUserGroup "#508" "#505"
ServerName mark.info
DocumentRoot /home/mark.info/public_html
ErrorLog /var/log/virtualmin/mark.info_error_log
CustomLog /var/log/virtualmin/mark.info_access_log combined
ScriptAlias /cgi-bin/ /home/mark.info/cgi-bin/
ScriptAlias /awstats/ /home/mark.info/cgi-bin/
DirectoryIndex index.html index.htm index.php index.php4 index.php5
<Directory /home/mark.info/public_html>
Options -Indexes +IncludesNOEXEC +SymLinksIfOwnerMatch +ExecCGI
allow from all
AllowOverride All Options=ExecCGI,Includes,IncludesNOEXEC,Indexes,MultiViews,SymLinksIfOwnerMatch
AddHandler fcgid-script .php
AddHandler fcgid-script .php5
FCGIWrapper /home/mark.info/fcgi-bin/php5.fcgi .php
FCGIWrapper /home/mark.info/fcgi-bin/php5.fcgi .php5
</Directory>
<Directory /home/mark.info/cgi-bin>
allow from all
AllowOverride All Options=ExecCGI,Includes,IncludesNOEXEC,Indexes,MultiViews,SymLinksIfOwnerMatch
</Directory>

thank you very much james. i had a look at the article you sent me (and also authored, thank you very much!) - does this article primarly apply to fast-cgi? and i didnt see a section labeled "How you can controll the number of the PHP processes."
i loved the commentary at the top:
| Quote: | One of the biggest topics here at Apache Lounge is running PHP on Apache.
It is a topic that is constant and for some reason often confused.
Confused namely by varying ways to accomplish the same thing. |
once again, any assistance is very greatly appreciated, especially tolerance for foolish newbies such as myself. |
