Linux platform PHP5.4 How to set the number of FPM threads _php Tips

This example describes the Linux platform PHP5.4 How to set the number of FPM threads. Share to everyone for your reference, specific as follows:

After the PHP5.4 is installed, the default profile for FPM is located in/usr/local/php/etc/php-fpm.conf.default

>cp/usr/local/php/etc/php-fpm.conf.default/usr/local/php/etc/php-fpm.conf
>vim/usr/local/php/etc/ Php-fpm.conf

Enter "/www" to search the pool at www

PM = dynamic; The number of child processes to being created when PM is set to ' static ' and ';
Maximum number of child processes when the PM is set to ' dynamic ' or ' OnDemand '. ; This value sets the limit on the number of simultaneous requests that would be; Served.
Equivalent to the apachemaxclients directive with Mpm_prefork. ; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP; Cgi. The below defaults are based on a server without much of the resources. Don ' t;
Forget to tweak pm.* to fit your needs. ; note:used when PM are set to ' static ', ' dynamic ' or ' OnDemand ';
Note:this value is mandatory. Pm.max_children = 5;
The number of child processes created on startup. ; Note:used only if PM is set to ' dynamic '; Default value:min_spare_servers + (max_spare_servers-min_spare_servers)/2 pm.start_servers = 2;
The desired minimum number of idle server processes. ; Note:used only if PM is set to ' dynamic '; Note:mandatory when PM are set to ' dynamic ' pm.min_spAre_servers = 1;
The desired maximum number of idle server processes. ; Note:used only if PM is set to ' dynamic '; Note:mandatory when PM are set to ' dynamic ' pm.max_spare_servers = 3;
The number of seconds after which a idle process would be killed. ; note:used only when the PM is set to ' OnDemand '; Default value:10s;p m.process_idle_timeout = 10s;;
The number of requests each child process should execute before respawning. ; This can is useful to work around memory leaks at 3rd party libraries. for; Endless request processing Specify ' 0 '.
Equivalent to Php_fcgi_max_requests. ;

 Default value:0;p m.max_requests = 500

Explain:

PM = How dynamic controls the subprocess, the options are static and dynamic, the default is dynamic, and if you choose Static, the number of fixed Pm.max_children is specified by the.

If dynamic is selected, it is determined by the following parameters:

Pm.max_children	Maximum number of child processes
Pm.start_servers	Number of processes at startup
Pm.min_spare_servers	Guarantees the minimum number of idle processes, and creates a new child process if the idle process is less than this value
Pm.max_spare_servers	The maximum number of idle processes is guaranteed, and cleanup is done if the idle process is greater than this value. For dedicated servers, PM can be set to static.
Pm.max_requests	Sets the number of requests for services before each subprocess is reborn. is useful for Third-party modules that may have memory leaks. If set to ' 0′, the request is always accepted. Set to 500 is OK (default 0).

Modify the value to read as follows:

Pm.max_children =
Pm.start_servers =
pm.min_spare_servers = 8
pm.max_spare_servers =
pm.max_ Requests = 500

: Wq Save quit Vim

>/usr/local/php/sbin/php-fpm-t
notice:configuration file/usr/local/php/etc/php-fpm.conf test is successful

Test configuration file is normal, no problem, kill the current FPM process

>/usr/local/php/sbin/php-fpm

Start
