nginx加入系统服务

将nginx加入系统服务，可用很方便的对nginx进行启动和停止等操作；本环境nginx安装在/usr/local/nginx目录，若你未安装在该目录需修改下面的shell脚本 DAEMON=/usr/local/nginx/sbin/$NAME 语句，指定nginx的安装目录。

新建nginx文件,添加内容(为方便显示对内容进行了缩进，你可以使用shift+tab来取消缩进至文件顶格)：

#! /bin/bash
# chkconfig: 35 85 15  
# description: Nginx is an HTTP(S) server, HTTP(S) reverse
set -e
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="nginx daemon"
NAME=nginx
DAEMON=/usr/local/nginx/sbin/$NAME
SCRIPTNAME=/etc/init.d/$NAME
test -x $DAEMON || exit 0
d_start(){
    $DAEMON || echo -n " already running"
}
d_stop() {
    $DAEMON -s quit || echo -n " not running"
}
d_reload() {
    $DAEMON -s reload || echo -n " counld not reload"
}
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 $DESC configuration..."
    d_reload
    echo "reloaded."
;;
restart)
    echo -n "Restarting $DESC: $NAME"
    d_stop
    sleep 2
    d_start
    echo "."
;;
*)
    echo "Usage: $SCRIPTNAME {start|stop|restart|reload}" >&2
    exit 3
;;
esac
exit 0

然后执行以下命令：

# 复制shell脚本nginx文件到目录/etc/rc.d/init.d/中
cp ./nginx  /etc/rc.d/init.d 	

chmod +x  /etc/rc.d/init.d/nginx 	# 设置文件可执行权限
chkconfig --add nginx  	# 添加至系统服务

任何目录执行命令即可操作nginx：

service nginx <start | stop | restart | reload > 	# <启动|停止|重启|重载> nginx
