nginx php-fpm memcached 均为编译安装，将脚本统一放置在/etc/init.d/ 下，形成启动服务的标准化。

一、编译安装后nginx启动、停止有些麻烦，将下面内容添加到/etc/init.d/nginx中，作为nginx的服务启动。

#!/bin/bash

#chkconfig: 345 85 15
#description:It is used to serve

PATH=/usr/local/nginx/sbin:$PATH
export PATH

# check if root account
if [ $(id -u) != "0" ];then
    printf "Error:You must be root account!\n"
    exit 1
fi

#Define environment variables
NGINX_PID=/usr/local/nginx/logs/nginx.pid
NGINX_DAEMON=/usr/local/nginx/sbin/nginx

#Function define
fun_start()
{
   printf "Starting nginx ...\n"
   if [ -f $NGINX_PID ];then
      printf "Nginx is running!\n"
      exit 1
    else
      $NGINX_DAEMON
      printf "Nginx start successfully!\n"
   fi
}

fun_stop()
{
   printf "Stoping Nginx...\n"
   if [ -f $NGINX_PID ];then
      kill $(cat $NGINX_PID)
      printf "Nginx is stopped!\n"
   else
      printf "Nginx is not running!\n"
   fi
}

fun_reload()
{
  printf "Reloading Nginx...\n"
  if [ -f $NGINX_PID ];then
     $NGINX_DAEMON -s reload
  else
     printf "Nginx is not running!\n"
  fi
}

fun_restart()
{
  printf "Restarting Nginx..."
  kill $(cat $NGINX_PID)
  $NGINX_DAEMON
}

fun_status()
{
  if [ -f $NGINX_PID ];then
     printf "Nginx is running!\n"
  else
     printf "Nginx is stop!\n"
  fi
}

case "$1" in
    start)
         fun_start
         ;;
    stop)
         fun_stop
         ;;
    restart)
         fun_stop
         fun_start
         ;;
     reload)
         fun_reload
         ;;
     status)
         fun_status
         ;;
      *)
         printf "Usage:Only {start|stop|restart|reload|status}"
esac
exit

说明：脚本中红色字体部分为将nginx添加为linux系统服务必须添加的语句，否则无法添加成功。
红色字体的意思为：启动级别 | 启动优先级 | 停止优先级
1、将nginx赋予执行权限，放置在/etc/init.d/下
2、chkconfig --add nginx

二、将php-fpm的启动脚本放置在/etc/init.d下
ln -s /usr/local/php5/sbin/php-fpm /etc/init.d/php-fpm

三、memcached启动脚本
   路径：/etc/init.d/memcached
        赋予执行权限


 #!/bin/bash

# check if root account
if [ $(id -u) != "0" ];then
    printf "Error:You must be root account!\n"
    exit 1
fi

memcache_prog=$(ps -ef | grep memcached | grep -v grep | wc -l)
memcache_pid=$(ps -ef | grep memcached | grep -v grep | awk '{print $2}')

mem=50
user=root
port=12000
fun_start()


  if [ $memcache_prog != "0" ];then
     printf "memcached is running !\n"
  else
     memcached -d -m $mem  -u $user -p $port
     printf "memcached is started!\n"
  fi

fun_stop()
  if [ $memcache_prog = "0" ];then
     printf "memcached is not running !\n"
  else
     kill $memcache_pid
     printf "memcached is stopped\n"
  fi

fun_status()
  if [ $memcache_prog != "0" ];then
     printf "memcached is running !\n"
  else
     printf "memcached is stopped!\n"
  fi


case "$1" in
   start)
         fun_start
          ;;
   stop)
         fun_stop
          ;;
   restart)
         fun_stop
         fun_start
          ;;
   status)
          fun_status
           ;;
     *)
         printf "Usage:Only {start | stop | restart | status }\n"

esac
exit
