Nginx 是一个很强大的高性能Web和反向代理服务器。下面介绍在Centos8下安装后，如何设置开机自启动。

首先，在linux系统的/etc/init.d/目录下创建nginx文件，使用如下命令：  
vim /etc/init.d/nginx  
  
在脚本中添加如下命令：

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
\#!/bin/bash  
\# nginx Startup script for the Nginx HTTP Server  
\# it is v.0.0.2 version.  
\# chkconfig: - 85 15  
\# description: Nginx is a high-performance web and proxy server.  
\#              It has a lot of features, but it's not for everyone.  
\# processname: nginx  
\# pidfile: /var/run/nginx.pid  
\# config: /usr/local/nginx/conf/nginx.conf  
**nginxd=/usr/local/nginx/sbin/nginx  
nginx\_config=/usr/local/nginx/conf/nginx.conf  
nginx\_pid=/var/run/nginx.pid**  
RETVAL=0  
prog="nginx"  
\# Source function library.  
. /etc/rc.d/init.d/functions  
\# Source networking configuration.  
. /etc/sysconfig/network  
\# Check that networking is up.  
\[ $\{NETWORKING\} = "no" \] && exit 0  
\[ -x $nginxd \] || exit 0  
\# Start nginx daemons functions.  
start() \{  
if \[ -e $nginx\_pid \];then  
   echo "nginx already running...."  
   exit 1  
fi  
   echo -n $"Starting $prog: "  
   daemon $nginxd -c $\{nginx\_config\}  
   RETVAL=$?  
   echo  
   \[ $RETVAL = 0 \] && touch /var/lock/subsys/nginx  
   return $RETVAL  
\}  
\# Stop nginx daemons functions.  
stop() \{  
        echo -n $"Stopping $prog: "  
        killproc $nginxd  
        RETVAL=$?  
        echo  
        \[ $RETVAL = 0 \] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid  
\}  
\# reload nginx service functions.  
reload() \{  
    echo -n $"Reloading $prog: "  
    \#kill -HUP \`cat $\{nginx\_pid\}\`  
    killproc $nginxd -HUP  
    RETVAL=$?  
    echo  
\}  
\# See how we were called.  
case "$1" in  
start)  
        start  
        ;;  
stop)  
        stop  
        ;;  
reload)  
        reload  
        ;;  
restart)  
        stop  
        start  
        ;;  
status)  
        status $prog  
        RETVAL=$?  
        ;;  
\*)  
        echo $"Usage: $prog \{start|stop|restart|reload|status|help\}"  
        exit 1  
esac  
exit $RETVAL  
  
\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

注意粉色加粗部分，需要将路径改为自己机器的相应路径。  
接着，设置文件的访问权限：  
chmod a+x /etc/init.d/nginx                 (a+x参数表示 ==> all user can execute  所有用户可执行)  
  
最后将nginx加入到rc.local文件中，这样开机的时候nginx就默认启动了  
vi /etc/rc.local  
添加  
/etc/init.d/nginx start     
保存并退出  
下次重启就会生效，实现nginx的自启动。
