lnmp搭建wordpress執行個體--啟動腳本

    nginx php-fpm memcached 均為編譯安裝，将腳本統一放置在/etc/init.d/ 下，形成啟動服務的标準化。

一、編譯安裝後nginx啟動、停止有些麻煩，将下面内容添加到/etc/init.d/nginx中，作為nginx的服務啟動。

#!/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"

      kill $(cat $NGINX_PID)

      printf "Nginx is stopped!\n"

   else

      printf "Nginx is not running!\n"

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()

     printf "Nginx is running!\n"

     printf "Nginx is stop!\n"

case "$1" in

    start)

         fun_start

         ;;

    stop)

         fun_stop

    restart)

     reload)

         fun_reload

     status)

         fun_status

      *)

         printf "Usage:Only {start|stop|restart|reload|status}"

esac

exit

-------------  < nginx script END>   --------------

說明：腳本中紅色字型部分為将nginx添加為linux系統服務必須添加的語句，否則無法添加成功。

紅色字型的意思為：啟動級别 | 啟動優先級 | 停止優先級

1、将nginx賦予執行權限，放置在/etc/init.d/下

2、chkconfig --add nginx

二、将php-fpm的啟動腳本放置在/etc/init.d下

ln -s /usr/local/php5/sbin/php-fpm /etc/init.d/php-fpm

三、memcached啟動腳本

   路徑：/etc/init.d/memcached

        賦予執行權限

 #!/bin/bash

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

  if [ $memcache_prog != "0" ];then

     printf "memcached is running !\n"

     memcached -d -m $mem  -u $user -p $port

     printf "memcached is started!\n"

  if [ $memcache_prog = "0" ];then

     printf "memcached is not running !\n"

     kill $memcache_pid

     printf "memcached is stopped\n"

     printf "memcached is stopped!\n"

   start)

          ;;

   stop)

   restart)

   status)

          fun_status

           ;;

     *)

         printf "Usage:Only {start | stop | restart | status }\n"

exit

-------------  <memcached script END>  ---------------------
