The pool of PHP-FPM

• To avoid using the same pool for multiple sites, a separate pool for each site needs to be configured if one site's traffic is too large to cause problems with resource exhaustion, which in turn affects the normal operation of other sites using the same pool. The way of implementation and Nginx Vhost almost

  PHP Slow Execution log
• Add the following two lines to the configuration file

  [[email protected] ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.confrequest_slowlog_timeout = 1#当请求超过1秒开始记录日志slowlog = /usr/local/php-fpm/var/log/www-slow.log#日志存放地址

• Test

  [[email protected] ~]# vim /data/wwwroot/test.com/sleep.php<?phpecho "test slow log";sleep(2);echo "done";?>[[email protected] ~]# curl -x127.0.0.1:80 test.com/sleep.phptest slow logdone[[email protected] ~]# cat /usr/local/php-fpm/var/log/www-slow.log [19-Jun-2018 08:58:20]  [pool www] pid 1451script_filename = /data/wwwroot/test.com/sleep.php[0x00007f4cadc922e0] sleep() /data/wwwroot/test.com/sleep.php:3

  Open_basedir
• When a server runs multiple sites, you can use the openBasedir to limit the range of directories on the servers that each site can access, and you need to set open basedir per pool

  [[email protected] ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.confphp_admin_value[open_basedir]=/data/wwwroot/eetest.com:/tmp/#故意写错/data/wwwroot/eetest.com，正确是/data/wwwroot/test.com

• To test

  [[email protected] ~]# curl -x127.0.0.1:80 test.com/sleep.php -IHTTP/1.1 404 Not FoundServer: nginx/1.14.0Date: Tue, 19 Jun 2018 01:21:13 GMTContent-Type: text/html; charset=UTF-8Connection: keep-aliveX-Powered-By: PHP/5.6.30

• Change www.conf again, modify the path, test again

• PM = dynamic process management, or static, when the following configuration does not take effect, the 50 child processes are generated without changing
• Pm.max_children = 50//maximum number of sub-processes, PS aux can be viewed
• Pm.start_servers = 20//Number of processes that will start when the service is started
• Pm.min_spare_servers = 5//Defines the minimum number of child processes in the idle period, and if this value is reached, the PHP-FPM service automatically derives the new child process.
• Pm.max_spare_servers = 35//Defines the maximum number of child processes in the idle period, or, if higher than this value, to start cleaning up idle child processes.
• Pm.max_requests = 500//defines the maximum number of requests processed by a child process, that is, in a PHP-FPM child process can handle so many requests, when this value is reached, it automatically exits
