php-fpm

• 设置慢查询日志

    slowlog=/var/log/php7.0/fpm/slow.log
    request_slowlog_timeout=1s
  

• 启动、重启、终止操作

  • 使用信号控制，master进程可以理解以下信号

    • INT, TERM 立刻终止
    • QUIT 平滑终止
    • USR1 重新打开日志文件
    • USR2 平滑重载所有worker进程并重新载入配置和二进制模块

  • php-fpm 关闭：

      kill -INT 'cat /usr/local/php/var/run/php-fpm.pid'
    

  • php-fpm 重启：

      kill -USR2 'cat /usr/local/php/var/run/php-fpm.pid'
    

• nginx 和 php-fpm 通信

  • TCP方式

    • php-fpm配置

        $ vim /usr/local/php/ete/php-fpm.conf
        
        listen=127.0.0.1:9000
      

    • nginx配置

        vim /usr/local/nginx/conf/nginx.conf
      
        fastcgi_pass 127.0.0.1:9000;

    • php-fpm配置

        $ vim /usr/local/php/ete/php-fpm.conf
        
        [global]
        pid = /usr/local/php/var/run/php-fpm.pid
        error_log = /usr/local/php/var/log/php-fpm.log
        log_level = notice
      
        [www]
        listen = /tmp/php-cgi.sock
        listen.backlog = -1
        listen.allowed_clients = 127.0.0.1
        listen.owner = www
        listen.group = www
        listen.mode = 0666
        user = www
        group = www
        pm = dynamic
        pm.max_children = 60
        pm.start_servers = 30
        pm.min_spare_servers = 30
        pm.max_spare_servers = 60
        request_terminate_timeout = 100
        request_slowlog_timeout = 0
        slowlog = var/log/slow.log
        catch_workers_output = yes
      

    • nginx配置
