nginx自启动linux

以下是在Linux上配置Nginx服务开机自启动的步骤：

1. 确保已经安装了chkconfig工具，如果没有安装，可以使用以下命令进行安装：

   yum install chkconfig -y

2. 创建一个名为nginx的脚本文件，并将其复制到/etc/init.d/目录下：

   sudo vi /etc/init.d/nginx

   #!/bin/sh
   #
   # nginx - this script starts and stops the nginx daemon
   #
   # 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
       sleep 1
       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

注意：脚本中的nginx路径和NGINX_CONF_FILE路径需要替换成自己的nginx安装路径。

3. 添加执行权限：

   sudo chmod +x /etc/init.d/nginx

4. 添加服务到chkconfig：

   sudo chkconfig --add nginx

5. 设置开机自启动：

   sudo chkconfig nginx on

6. 启动Nginx服务：

   sudo service nginx start
