• 为了避免因多站点使用同一个pool时,如果一个站点访问量过大导致资源耗尽出现问题，进而影响使用同一个pool的其他站点的正常运行，就需要对每个站点配置一个单独的pool。实现方式和nginx的vhost差不多
• 编辑主配置文件

  [root@akuilinux01 aming.com]# vim /usr/local/php-fpm/etc/php-fpm.conf
  [global]
  pid = /usr/local/php-fpm/var/run/php-fpm.pid
  error_log = /usr/local/php-fpm/var/log/php-fpm.log
  include = etc/php-fpm.d/*.conf

• 重建多个pool

  [root@akuilinux01 aming.com]# mkdir /usr/local/php-fpm/etc/php-fpm.d
  [root@akuilinux01 aming.com]# cd !$
  cd /usr/local/php-fpm/etc/php-fpm.d
  [root@akuilinux01 php-fpm.d]# vim www.conf
  [www]
  listen = /tmp/php-fcgi.sock
  #listen = 127.0.0.1:9000
  listen.mode = 666
  user = php-fpm
  group = php-fpm
  pm = dynamic
  pm.max_children = 50
  pm.start_servers = 20
  pm.min_spare_servers = 5
  pm.max_spare_servers = 35
  pm.max_requests = 500
  rlimit_files = 1024  
  [root@akuilinux01 php-fpm.d]# vim aming.conf
  [aming]
  listen = /tmp/aming.sock
  #listen = 127.0.0.1:9000
  listen.mode = 666
  user = php-fpm
  group = php-fpm
  pm = dynamic
  pm.max_children = 50
  pm.start_servers = 20
  pm.min_spare_servers = 5
  pm.max_spare_servers = 35
  pm.max_requests = 500
  rlimit_files = 1024
  [root@akuilinux01 php-fpm.d]# /usr/local/php-fpm/sbin/php-fpm -t

  PHP慢执行日志

• 配置文件中加入下面两行

  [root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
  request_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

• 测试

  [root@akuilinux01 ~]# vim /data/wwwroot/test.com/sleep.php
  <?php
  echo "test slow log";
  sleep(2);
  echo "done";
  ?>
  [root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php
  test slow logdone
  [root@akuilinux01 ~]# cat /usr/local/php-fpm/var/log/www-slow.log 
  [19-Jun-2018 08:58:20]  [pool www] pid 1451
  script_filename = /data/wwwroot/test.com/sleep.php
  [0x00007f4cadc922e0] sleep() /data/wwwroot/test.com/sleep.php:3

  open_basedir

• 当一台服务器跑多个站点时，可以使用openbasedir限定各个站点所能访问的服务器上的目录的范围，就需要每个pool设定open basedir

  [root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
  php_admin_value[open_basedir]=/data/wwwroot/eetest.com:/tmp/
  #故意写错/data/wwwroot/eetest.com，正确是/data/wwwroot/test.com

• 进行测试

  [root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php -I
  HTTP/1.1 404 Not Found
  Server: nginx/1.14.0
  Date: Tue, 19 Jun 2018 01:21:13 GMT
  Content-Type: text/html; charset=UTF-8
  Connection: keep-alive
  X-Powered-By: PHP/5.6.30

• 再次更改www.conf，修改路径，再次测试

  [root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf 
  [root@akuilinux01 ~]# /etc/init.d/php-fpm restart
  Gracefully shutting down php-fpm . done
  Starting php-fpm  done
  [root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php
  test slow logdone

• 配置错误日志

  [root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php.ini
  error_reporting = E_ALL
  display_errors = Off
  ;error_log = syslog
  error_log = /usr/local/php-fpm/var/log/php_errors.log
  [root@akuilinux01 ~]# touch /usr/local/php-fpm/var/log/php_errors.log
  [root@akuilinux01 ~]# chmod 777 /usr/local/php-fpm/var/log/php_errors.log
  [root@akuilinux01 ~]# /etc/init.d/php-fpm restart
  Gracefully shutting down php-fpm . done
  Starting php-fpm  done

• 再次测试，测试前故意改错

  [root@akuilinux01 ~]# vim /usr/local/php-fpm/etc/php-fpm.d/www.conf
  php_admin_value[open_basedir]=/data/wwwroot/eetest.com:/tmp/
  #故意写错/data/wwwroot/eetest.com，正确是/data/wwwroot/test.com

  [root@akuilinux01 ~]# curl -x127.0.0.1:80 test.com/sleep.php -I
  HTTP/1.1 404 Not Found
  Server: nginx/1.14.0
  Date: Tue, 19 Jun 2018 01:34:14 GMT

  php-fpm进程管理

  [root@akuilinux01 ~]# cat /usr/local/php-fpm/etc/php-fpm.d/www.conf
  [www]
  listen = /tmp/www.sock
  ;listen = 127.0.0.1:9000
  listen.mode = 666
  user = php-fpm
  group = php-fpm
  pm = dynamic
  pm.max_children = 50
  pm.start_servers = 20
  pm.min_spare_servers = 5
  pm.max_spare_servers = 35
  pm.max_requests = 500
  rlimit_files = 1024 
  request_slowlog_timeout = 1
  slowlog = /usr/local/php-fpm/var/log/www-slow.log
  php_admin_value[open_basedir]=/data/wwwroot/test.com:/tmp/

• pm = dynamic //动态进程管理，也可以是static,这时下面的配置不生效启动就生成50个子进程不会改变
• pm.max_children = 50 //最大子进程数，ps aux可以查看
• pm.start_servers = 20 //启动服务时会启动的进程数
• pm.min_spare_servers = 5 //定义在空闲时段，子进程数的最少数量，如果达到这个数值时，php-fpm服务会自动派生新的子进程。
• pm.max_spare_servers = 35 //定义在空闲时段，子进程数的最大值，如果高于这个数值就开始清理空闲的子进程。
• pm.max_requests = 500 //定义一个子进程最多处理的请求数，也就是说在一个php-fpm的子进程最多可以处理这么多请求，当达到这个数值时，它会自动退出
