CentOS 添加nginx到系统服务(service)

1. 简介

nginx源码安装完成后默认不会注册为系统服务，所以需要手工添加系统服务脚本。在/etc/init.d目录下新建nginx文件，并更改权限其即可。

2. 新建nginx文件

vim /etc/init.d/nginx
填写一下内容(根据自己的实际目录修改):

#! /bin/sh
 
### BEGIN INIT INFO
# Provides:          nginx
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts the nginx web server
# Description:       starts nginx using start-stop-daemon
### END INIT INFO
 
# Author:   
# website:

PIDFILE=/usr/local/nginx/logs/$NAME.pid
 
case "$1" in
    start)
        echo -n "Starting $NAME... "
 
        if netstat -tnpl | grep -q nginx;then
            echo "$NAME (pid `pidof $NAME`) already running."
            exit 1
        fi
 
        $NGINX_BIN -c $CONFIGFILE
 
        if [ "$?" != 0 ] ; then
            echo " failed"
            exit 1
        else
            echo " done"
        fi
        ;;
 
    stop)
        echo -n "Stoping $NAME... "
 
        if ! netstat -tnpl | grep -q nginx; then
            echo "$NAME is not running."
            exit 1
        fi
 
        $NGINX_BIN -s stop
 
        if [ "$?" != 0 ] ; then
            echo " failed. Use force-quit"
            exit 1
        else
            echo " done"
        fi
        ;;
 
    status)
        if netstat -tnpl | grep -q nginx; then
            PID=`pidof nginx`
            echo "$NAME (pid $PID) is running..."
        else
            echo "$NAME is stopped"
            exit 0
        fi
        ;;
 
    force-quit)
        echo -n "Terminating $NAME... "
 
        if ! netstat -tnpl | grep -q nginx; then
            echo "$NAME is not running."
            exit 1
        fi
 
        kill `pidof $NAME`
 
        if [ "$?" != 0 ] ; then
            echo " failed"
            exit 1
        else
            echo " done"
        fi
        ;;
 
    restart)
        $0 stop
        sleep 1
        $0 start
        ;;
 
    reload)
        echo -n "Reload service $NAME... "
 
        if netstat -tnpl | grep -q nginx; then
            $NGINX_BIN -s reload
            echo " done"
        else
            echo "$NAME is not running, can't reload."
            exit 1
        fi
        ;;
 
    configtest)
        echo -n "Test $NAME configure files... "
 
        $NGINX_BIN -t
        ;;
 
    *)
        echo "Usage: $0 {start|stop|force-quit|restart|reload|status|configtest}"
        exit 1
        ;;
esac

tip:
根据自己实际安装目录，修改这两行:

NGINX_BIN=/usr/local/nginx/sbin/$NAME
CONFIGFILE=/usr/local/nginx/conf/$NAME.conf
PIDFILE=/usr/local/nginx/logs/$NAME.pid

tip:
根据自己实际安装目录，修改这两行:

nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/var/run/nginx.pid

3. 修改文件权限

chmod 755 /etc/init.d/nginx

4. 设置开机启动

chkconfig nginx on

5. 查看开机启动的服务

chkconfig --list

6. 备注

启动服务：service nginx start

停止服务：service nginx stop

重启服务：service nginx reload
