Pool configuration for PHP-FPM

Nginx can open more than one virtual machine, they all need PHP to provide services, so in order to ensure the performance of each different virtual machine, you can open multiple PHP-FPM pool service. Each pool serves one site.

Method 1:
Add content to/usr/local/php-fpm/etc/php-fpm.conf:

Two modules are named with different names, and the names of the sockets that are monitored are not the same. Set the corresponding path in the vhost corresponding Conf.  [Www]listen =/tmp/www.socklisten.mode=666user = Php-fpmgroup = PHP-FPMPM = Dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024[shuai.

Using pool:

[root@shuai-01 etc]# cd/usr/local/nginx/conf/vhost/[root@shuai-01 vhost]# lsaaa.com.conf  ld.conf  proxy.conf  ssl.conf  test.com.conf

A definition:

[Root@shuai-01 vhost]# VI test.com.conf

One is defined as:

[Root@shuai-01 vhost]# VI aaa.com.conf

Method 2:
The first method appears to be not neat enough. Can resemble the include statement when Nginx adds a virtual machine.

Add content to/usr/local/php-fpm/etc/php-fpm.conf:
Include = etc/php-fpm.d/*.conf
Then remove the following configuration statement.

Mkdir/usr/local/php-fpm/etc/php-fpm.d/cd/usr/local/php-fpm/etc/php-fpm.d/vim www.conf//content is as follows [Www]listen =/tmp/ Www.socklisten.mode=666user = Php-fpmgroup = PHP-FPMPM = Dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_ Servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024vim aming.conf//content is as follows [Aming]listen =/tmp/amin G.sock  //Listener sock names are different listen.mode=666user = Php-fpmgroup = PHP-FPMPM = Dynamicpm.max_children = 50pm.start_servers = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 1024//Check vhost conf file, The corresponding changes are monitored sock/usr/local/php-fpm/sbin/php-fpm-t  //Verify that the configuration is correct service php-fpm restart  //restart PS aux |grep php-fpm  //Found aming and www all appeared

Slow execution Log

PHP-FPM has a very useful function, which is to slow down the execution log. It can be very effective to diagnose the problem of the system where. Especially when the system is slow to access.

Vim/usr/local/php-fpm/etc/php-fpm.d/www.conf
Add the following:
Request_slowlog_timeout = 1//execute more than one second of statement recording down, production environment, here generally write 2 seconds
Slowlog =/usr/local/php-fpm/var/log/www-slow.log//Log storage directory

vim/data/wwwroot/test.com/sleep.php//writes the following <?php echo "Test slow Log"; Sleep (2); echo "Done"; >[root@cent01 vhost]# curl-x127.0.0.1:80 test.com/sleep.php  //test

A 502 error occurred during the test, and the *.sock in the pool was in the main configuration file.

Test slow logdone[root@cent01 vhost]# cat/usr/local/php-fpm/var/log/www-slow.log  //Slow log tip the third line takes too much time [16-nov-2017 20:20:39]  [pool www] pid 14208script_filename =/data/nginx/test.com/sleep.php[0x00007f630f62f270] Sleep ()/data/ Nginx/test.com/sleep.php:3

When the php file encounters an error, the error can be found in the/etc/init.d/php-fpm.ini file to open the Display_error function, so that errors can be displayed directly on the browser.

Open_basedir

Open_basedir if defined in php.ini is not appropriate, defined in the pool just as well, defined in Apache in the virtual host configuration file.

You can add the following statement directly in the/usr/local/php-fpm/etc/php-fpm.d/www.conf:

php_admin_value[open_basedir]=/data/nginx/aming.com:/tmp/

Restart Service php-fpm Restart or/ETC/INIT.D/PHP-FPM after configuration is complete restart

Where the path needs to be configured correctly. Otherwise you will get an error.

Change the configuration file to the following lines.

[Root@shuai-01 php-fpm.d]# Vi/usr/local/php-fpm/etc/php.ini Error_log=/usr/local/php-fpm/var/log/php_ Errors.logerror_reporting=e_alldisplay_errors = Offlog_errors = On

Create a file that holds the error log

[root@shuai-01 php-fpm.d]# touch/usr/local/php-fpm/var/log/php_errors.log[root@shuai-01 php-fpm.d]# chmod 777/usr/ Local/php-fpm/var/log/php_errors.log
