   startup.sh

  

#!/bin/bash
/home/yanlei/nginx/sbin/nginx -p /home/yanlei/nginx -c /home/yanlei/conf/nginx-8080.conf
 -g "pid /home/yanlei/pid/nginx-8080.pid;"

  stop.sh

  

#!/bin/bash
/home/yanlei/nginx/sbin/nginx -p /home/yanlei/nginx -c /home/yanlei/conf/nginx-8080.conf 
-g "pid /home/yanlei/pid/nginx-8080.pid;" -s stop

 reload.sh

#!/bin/bash
/home/yanlei/nginx/sbin/nginx -p /home/yanlei/nginx -c /home/yanlei/conf/nginx-8080.conf 
-g "pid /home/yanlei/pid/nginx-8080.pid;" -s stop

   改完配置后，使用 reload.sh重新加载配置，如果配置有错误会得到提示，可继续修改，对生产无影响。

   如果配置无错误，新的配置生效，生产服务无间断。
