PHP实现统计在线人数的方法_php教程
PHP是在服务器端执行的脚本语言，与C语言类似，是常用的网站编程语言。本文就来为大家介绍一下使用php实现统计在线人数的方法。

安装完php,使用chkconfig命令来查看php-fpm服务是否开启，如果没有开启

1、在/etc/init.d/目录下创建脚本php-fpm

vim/etc/init.d/php-fpm

2、编写脚本内容（将一下复制进去相应改动安装路径）

#!/bin/sh
     #
     # php-fpm - this script starts and stops the php-fpm daemin
     #
     # chkconfig: - 85 15
     # processname: php-fpm
     # config:      /usr/local/php/etc/php-fpm.conf
     set -e
     PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
     DESC="php-fpm daemon"
     NAME=php-fpm
     DAEMON=/usr/local/php/sbin/$NAME                 //这里改成之前的安装目录
     CONFIGFILE=/usr/local/php/etc/php-fpm.conf      //这里改成之前的安装目录
     PIDFILE=/usr/local/php/var/run/$NAME.pid         //这里改成之前的安装目录
     SCRIPTNAME=/etc/init.d/$NAME                         //这里改成之前的安装目录    
     # If the daemon file is not found, terminate the script.
     test -x $DAEMON || exit 0
     d_start(){
         $DAEMON -y $CONFIGFILE || echo -n " already running"
     }
     d_stop(){
         kill -QUIT `cat $PIDFILE` || echo -n " no running"
     }
     d_reload(){
         kill -HUP `cat $PIDFILE` || echo -n " could notreload"
     }
     case "$1" in
         start)
             echo -n "Starting $DESC: $NAME"
             d_start
             echo "."
             ;;
         stop)
             echo -n "Stopping $DESC: $NAME"
             d_stop
             echo "."
             ;;
         reload)
             echo -n "Reloading $DESCconfiguration..."
             d_reload
             echo "Reloaded."
             ;;
         restart)
             echo -n "Restarting $DESC: $NAME"
             d_stop
             # Sleep for two seconds before startingagain, this should give the nginx daemon some time to perform a graceful stop
             sleep 2
             d_start
             echo "."
             ;;
         *)
             echo "Usage: $SCRIPTNAME{start|stop|restart|force-reload)" >&2
             exit 3
             ;;
     esac
     exit 0

最后：wq退出保存；
