方案1:设置nginx开机自启动(CentOS):

创建nginx启动命令脚本 /etc/init.d/nginx :

注意修改以下两项配置:
nginx=”/usr/local/nginx/sbin/nginx”
NGINX_CONF_FILE=”/usr/local/nginx/conf/nginx.conf”

#! /bin/bash
# chkconfig: - 85 15
PATH=/usr/local/nginx
DESC="nginx daemon"
NAME=nginx
DAEMON=$PATH/sbin/$NAME
CONFIGFILE=$PATH/conf/$NAME.conf
PIDFILE=$PATH/logs/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
set -e
[ -x "$DAEMON" ] || exit 0
do_start() {
$DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}
do_stop() {
$DAEMON -s stop || echo -n "nginx not running"
}
do_reload() {
$DAEMON -s reload || echo -n "nginx can't reload"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."
;;
reload|graceful)
echo -n "Reloading $DESC configuration..."
do_reload
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac
exit 0

Nginx服务设置:dos2unix 转换/设置执行权限/注册成服务/设置开机启动

dos2unix /etc/init.d/nginx && chmod a+x /etc/init.d/nginx && chkconfig --add nginx && chkconfig nginx on

方案2:设置nginx开机自启动(Ubuntu):

因为发现服务器没有设置Nginx开机自启动,就网上搜了一下,找了个启动脚本,设置一下。
正文

Ubuntu/Linux系统开机自启动,很简单,在/etc/init.d/目录下编写一个服务脚本(比如nginx),然后在/etc/init.d/rc.local中添加一行启动命令。操作步骤如下

1. vi /etc/init.d/nginx ,其中具体的脚本展示如下:

#!/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
 
#注意:这里的三个变量需要根据具体的环境而做修改。
nginxd=/opt/nginx/sbin/nginx
nginx_config=/opt/nginx/conf/nginx.conf
nginx_pid=/opt/nginx/logs/nginx.pid
RETVAL=0
prog="nginx"
 
# Check that networking is up.
[ -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: "
   $nginxd -c ${nginx_config}
   RETVAL=$?
   echo
   [ $RETVAL = 0 ]  
   return $RETVAL
}
# Stop nginx daemons functions.
stop() {
  echo -n $"Stopping $prog: "
  $nginxd -s stop
  RETVAL=$?
  echo
  [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx $nginx_pid
}
# reload nginx service functions.
reload() {
  echo -n $"Reloading $prog: "
  kill -HUP `cat ${nginx_pid}`
  RETVAL=$?
  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

2. 赋予可执行权限:

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

3.编辑 /etc/rc.local ,在文件的最后中添加:

/etc/init.d/nginx start

然后,nginx可以通过 /etc/init.d/nginx start或者 service nginx start进行启动。

     #the min number is 3,even if the nginx is not running 
     if [ $Statusflag -gt 3 ]; then
         PID=`ps -ef | grep nginx | head -1 | awk '{print $2}'`  
         log_begin_msg "Stopping Nginx server"  
         if [ ! -z "$PID" ]; then  
            kill -15 $PID

        log_end_msg 0  
     else
        log_begin_msg "Nginx is not running"
        log_end_msg 0
     fi
     #$0 start it would be wrong to call this function directly.    
         log_begin_msg "Starting Nginx server"  
         /usr/local/openresty/nginx/sbin/nginx  
         log_end_msg 0 
     ;;   

  *)  
     log_success_msg "Usage: service nginx {start|stop|restart|status}"  
     exit 1  
esac  
exit 0 

将上述内容保存为nginx放在/etc/init.d/目录下 ,然后执行:

sudo chmod +x ./nginx
sudo update-rc.d nginx defaults

就可以使用service nginx {start|stop|restart|status} 了,优点是支持status,网上脚本大多没有加入查看status。缺点是没有根据nginx.pid查找进程运行状况,直接用的ps命令搜索nginx进程信息,kill -15可能会阻塞,无法杀掉进程。

最后发现还是官方写的最好,但是自己编译的二进制程序,建议取消upgrade选项,因为会改变二进制程序,贴下官方的:
