6, configure PHP-FPM 6, configure PHP-FPM 5.1 Introduction:

The PHP-FPM (FastCGIProcess Manager: FastCGI Process Manager)

The PHP-FPM is a PHPFastCGI manager that is only used for PHP. It provides a better PHP process management method, which can effectively control the memory and processes, and can smoothly reload PHP configurations. it has more advantages than spawn-fcgi, so it is officially recorded by PHP. You can enable PHP-fpm with the enable-FPM parameter in./configure.

Use PHP-FPM to control FastCGI processes of PHP-CGI

/Usr/local/php/sbin/php-fpm {start | stop | quit | restart | reload | logrotate}

-- Start the fastcgi process of php

-- Stop force terminate the fastcgi process of php

-- Quit: smoothly terminate the fastcgi process of php

-- Restart the fastcgi process of php

-- Reload re-smoothly loads php. ini

-- Logrotate re-enable log files

5.2 configure php-fpm:

2.1 provide the SysV init script for php-fpm and add it to the service list:

[root@web tool]# cd php-5.5.34[root@web php-5.5.34]# cpsapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm[root@web php-5.5.34]# chmod +x/etc/rc.d/init.d/php-fpm[root@web php-5.5.34]# chkconfig --addphp-fpm[root@webphp-5.5.34]# chkconfig php-fpm on

2.2 provide the configuration file for php-fpm:

[root@webphp-5.5.34] # cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

2.3 edit the configuration file of php-fpm:

[Root@webphp-5.5.34] # vim/usr/local/php/etc/php-fpm.conf configure fpm related options for the value you need, pid File: pm is enabled by default. max_children = 50pm. start_servers = 5. min _spare_servers = 2. max_spare_servers = 8

2.4 then you can start php-fpm:

[Root @ web php-5.5.34] # service php-fpm startStarting php-fpm done description: php-fpm available parameter start | stop | force-quit | restart | reload | status

2.5 for ease of use, you can add the PHP command to the environment variable

[Root @ web php-5.5.34] # vim ~ /. Bash_profile #. bash_profile # Get the aliases and functionsif [-f ~ /. Bashrc]; then .~ /. Bashrcfi # User specific environment and startupprograms # Change PATH = $ PATH: $ HOME/bin to: PATH = $ PATH: $ HOME/bin: /usr/local/php/binPATH = $ PATH: $ HOME/bin:/usr/local/php/bin export PATH save and exit!

Make PHP environment variables take effect: [root@webphp-5.5.34] #. ~ /. Bash_profile

5.3 inspection:

Run the following command to verify the running status (if the command output contains several php-fpm processes, the startup is successful ):

[root@web php]# psaux | grep php-fpmroot      54722 0.0  0.3 175728  5932 ?       Ss   20:19   0:00 php-fpm: master process(/usr/local/php/etc/php-fpm.conf)                                                                   www       54723 0.0  0.2 175728  5144 ?

S    20:19   0:00 php-fpm: pool www                                                                                                           www       54726 0.0  0.2 175728  5144 ?       S    20:19   0:00 php-fpm: pool www                                                                                                           www       54727 0.0  0.2 175728  5144 ?       S    20:19   0:00 php-fpm: pool www                                                                                                           root      54837 0.0  0.0 103308   852 pts/1   S+   20:22   0:00 grep php-fpm

By default, fpm listens to Port 9000 of port 127.0.0.1. you can also run the following command to check whether it has been listened on the corresponding socket.

[root@web php-5.5.34]#netstat -tnlp | grep php-fpmtcp        0     0 127.0.0.1:9000             0.0.0.0:*                   LISTEN      54722/php-fpm

5.4 enable httpd-related modules

After Apache httpd 2.4, there has been a dedicated module for FastCGI implementation. this module is mod_proxy_fcgi.so, which is actually used as an extension of the mod_proxy.so module. Therefore, both modules must be loaded.

[root@web php-5.5.34]# vim/etc/httpd24/httpd.conf 115 LoadModule proxy_module modules/mod_proxy.so119 LoadModule proxy_fcgi_modulemodules/mod_proxy_fcgi.so

Then reload the httpd service:

[root@web php-5.5.34]# service httpd reload

5.5 configure the VM to support fcgi

1. change the httpd-vhosts.conf configuration to add lines similar to the following in the appropriate virtual host.

ProxyRequests Off

ProxyPassMatch ^/(. * \. php) $ fcgi: // 127.0.0.1: 9000/PATH/TO/DOCUMENT_ROOT/$1

[root@web extra]# vim httpd-vhosts.conf
 
     ServerAdmin webmaster@dummy-host.example.com   DocumentRoot "/usr/local/apache/htdocs/www/"   ServerName www.52linux.com    ProxyRequests Off    ProxyPassMatch ^/(.*\.php)$fcgi://127.0.0.1:9000/usr/local/apache/htdocs/www/$1   ErrorLog "logs/www_error_log"   CustomLog "logs/www_access_log" common
  
 
     ServerAdmin webmaster@dummy-host2.example.com   DocumentRoot "/usr/local/apache/htdocs/blog/"   ServerName  blog.52linux.com    ProxyRequests Off    ProxyPassMatch ^/(.*\.php)$fcgi://127.0.0.1:9000/usr/local/apache/htdocs/blog/$1   ErrorLog "logs/blog_error_log"   CustomLog "logs/blog_access_log" common
  
 
     ServerAdmin webmaster@dummy-host2.example.com    DocumentRoot"/usr/local/apache/htdocs/bbs/"   ServerName bbs.52linux.com    ProxyRequests Off    ProxyPassMatch ^/(.*\.php)$fcgi://127.0.0.1:9000/usr/local/apache/htdocs/bbs/$1   ErrorLog "logs/bbs_error_log"   CustomLog "logs/bbs_access_log"   comomn
 

ProxyRequests Off: disable forward proxy

ProxyPassMatch. the file request ending with php is sent to the php-fpm process. php-fpm must at least know the running directory and URI: the two parameters are specified after 9000. the passing of other parameters has been encapsulated by mod_proxy_fcgi.so and does not need to be specified manually.

2. edit the apache configuration file httpd. conf so that apache can recognize pages in php format and support the php homepage.

[Root @ web extra] # vim/etc/httpd24/httpd. conf #1 add the following two lines: 388 AddTypeapplication/x-httpd-php. php389 AddType application/x-httpd-php-source. phps

#2 set the location to directoryindexindex.html to 257
 
  
258 DirectoryIndex index.phpindex.html 259
 

In versions earlier than Apache httpd 2.4, either PHP is run as an Apache module or a third-party module is added to support PHP-FPM implementation.
