Linux怎么设置nginx开机启动

在Linux系统中，可以通过以下步骤设置nginx开机启动：

1. 打开终端，使用root权限登录Linux系统。

2. 进入/etc/init.d目录，创建nginx服务的启动脚本文件nginx。

   cd /etc/init.d
   touch nginx

3. 编辑nginx启动脚本文件，输入以下内容：

   #!/bin/sh
   #
   # nginx - this script starts and stops the nginx daemin
   #
   # chkconfig:   - 85 15
   # description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
   #               proxy and IMAP/POP3 proxy server
   # processname: nginx
   # config:      /usr/local/nginx/conf/nginx.conf
   # pidfile:     /usr/local/nginx/logs/nginx.pid

   # Source function library.
   . /etc/rc.d/init.d/functions

   # Source networking configuration.
   . /etc/sysconfig/network

   # Check that networking is up.
   [ "$NETWORKING" = "no" ] && exit 0

   nginx="/usr/local/nginx/sbin/nginx"
   prog=$(basename $nginx)

   NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"

   [ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

   lockfile=/var/lock/subsys/nginx

   start() {
       [ -x $nginx ] || exit 5
       [ -f $NGINX_CONF_FILE ] || exit 6
       echo -n $"Starting $prog: "
       daemon $nginx -c $NGINX_CONF_FILE
       retval=$?
       echo
       [ $retval -eq 0 ] && touch $lockfile
       return $retval
   }

   stop() {
       echo -n $"Stopping $prog: "
       killproc $prog -QUIT
       retval=$?
       echo
       [ $retval -eq 0 ] && rm -f $lockfile
       return $retval
   }

   restart() {
       configtest || return $?
       stop
       start
   }

   reload() {
       configtest || return $?
       echo -n $"Reloading $prog: "
       killproc $nginx -HUP
       RETVAL=$?
       echo
   }

   force_reload() {
       restart
   }

   configtest() {
       $nginx -t -c $NGINX_CONF_FILE
   }

   rh_status() {
       status $prog
   }

   rh_status_q() {
       rh_status >/dev/null 2>&1
   }

   case "$1" in
       start)
           rh_status_q && exit 0
           $1
           ;;
       stop)
           rh_status_q || exit 0
           $1
           ;;
       restart|configtest)
           $1
           ;;
       reload)
           rh_status_q || exit 7
           $1
           ;;
       force-reload)
           force_reload
           ;;
       status)
           rh_status
           ;;
       condrestart|try-restart)
           rh_status_q || exit 0
           restart
           ;;
       *)
           echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
           exit 2
   esac

4. 将nginx启动脚本文件添加执行权限。

   chmod +x nginx

5. 加入系统服务，设置nginx服务开机自启动。

   chkconfig --add nginx
   chkconfig nginx on

现在，nginx已经被设置为开机启动了。
