51.PHP-FPM pool, php-fpm slow execution log open_basedir, php-fpm process

First, the pool of PHP-FPM

vim /usr/local/php-fpm/etc/php-fpm.conf          //在[global]部分增加

 include = etc/php-fpm.d/*.conf                        //类似nginx的vhost

 mkdir /usr/local/php-fpm/etc/php-fpm.d/ cd /usr/local/php-fpm/etc/php-fpm.d/

 vim www.conf                                                  //内容如下

[www]listen = /tmp/php-fcgi.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

• Continue editing the configuration file

 vim chinantfy.conf //内容如下

[chinantfy]listen = /tmp/chinantfy.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

/usr/local/php-fpm/sbin/php-fpm -t /etc/init.d/php-fpm restart/reload            //重启或者重新加载配置文件 ps aux | grep php-fpm

ls /usr/local/nginx/conf/vhost/vim /usr/local/nginx/conf/vhost/test.com.conf

• Select different connection pools by specifying different sock two, php-fpm slow execution log (used to locate PHP Web site access is slow)

  vim /usr/local/php-fpm/etc/php-fpm.d/www.conf      //加入如下内容request_slowlog_timeout = 1        //超过1秒就会记录，一般用2 即可slowlog = /usr/local/php-fpm/var/log/www-slow.log

• Reload Nginx Service

  /usr/local/nginx/sbin/nginx -t/etc/init.d/nginx  reload

  vim /data/wwwroot/test.com/sleep.php         //写入如下内容<?php echo "test slow log";sleep(2);echo "done";?>

  curl -x127.0.0.1:80 test.com/sleep.php cat /usr/local/php-fpm/var/log/www-slow.log

• Log file shows that the third line of PHP causes slow running

  Third, PHP-FPM definition Open_basedir

  vim /usr/local/php-fpm/etc/php-fpm.d/www.conf    //加入如下内容

  php_admin_value[open_basedir]=/data/wwwroot/123test.com:/tmp/      //注意这里路径特意改错了

  /usr/local/php-fpm/sbin/php-fpm -t/etc/init.d/php-fpm reload

  curl -x127.0.0.1:80 test.com/sleep.php  -I

• Configuration error Log

  vi /usr/local/php-fpm/etc/php.ini   //修改下面两行error_log=/usr/local/php-fpm/var/log/php_errors.1ogerror_reporting =E_ALL

  /usr/local/php-fpm/sbin/php-fpm -t/etc/init.d/php-fpm reload

• Manually generate log files and modify permissions

  touch /usr/local/php-fpm/var/log/php_errors.1ogchmod 777 /usr/local/php-fpm/var/log/php_errors.1og

• Test again

  curl -x127.0.0.1:80 test.com/sleep.php  -I

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

  php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp//usr/local/php-fpm/sbin/php-fpm -t/etc/init.d/php-fpm reload

  Test again
  Viewing the error log

  Iv. PHP-FPM Process Management

  cat /usr/local/php-fpm/etc/php-fpm.d/www.conf

  PM = dynamic/Active process management, can also be static when the following line settings do not take effect
  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, a PHP-FPM child process can handle so many requests, and when this value is reached, it exits automatically.
