lnmp搭建wordpress实例--启动脚本

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

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

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

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