设置Nginx在linux服务器（Ubuntu）开机启动

1）首先需要安装 sysv-rc-conf 

 先更新一下  ：

sudo apt-get update

然后：  

apt install sysv-rc-conf   

输入下载命令，下载好了，中间需要输入 y 确认命令

 2）设置nginx开机启动：

我们自己编译安装的NGINX在/etc/init.d/下并没有管理脚本，所以我们现在还无法为NGINX设置自启动项，我们得先为NGINX在/etc/init.d/下创建一个启动脚本。

vi  /etc/init.d/nginx

内容如下：

#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for nginx webserver on Debian. Place in /etc/init.d and
# run 'update-rc.d -f nginx defaults', or use the appropriate command on your
# distro. For CentOS/Redhat run: 'chkconfig --add nginx'

        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

        ;;

    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

保存成功之后我们要对这个管理脚本设置一个权限：

chmod +x /etc/init.d/nginx

接下来我们可以看看这个脚本能否正确执行：

/etc/init.d/nginx restart #这个管理脚本支持的命令有start|stop|force-quit|restart|reload|status|configtest

如果没有错误能正确执行，那我们可以开始把他加入启动项了：

sysv-rc-conf --list #我们先查看一下list中有没有我们刚刚加进去的这个nginx管理脚本
sysv-rc-conf nginx on #然后用这个命令添加开机自启动

参考：

Ubuntu安装sysv-rc-conf安装使用报错 E: Unable to locate package sysv-rc-conf

Debian/Ubuntu下使用sysv-rc-conf将NGINX设置为自启动
