http://blog.51cto.com/myhat/images/editer/InBlock.gif1、备份nginx的可执行程序：

http://blog.51cto.com/myhat/images/editer/InBlock.gif [root@svr2 sbin]# cp nginx /root/nginx_old

http://blog.51cto.com/myhat/images/editer/InBlock.gif [root@svr2 sbin]# pwd

http://blog.51cto.com/myhat/images/editer/InBlock.gif /usr/local/webserver/nginx/sbin

http://blog.51cto.com/myhat/images/editer/InBlock.gif

http://blog.51cto.com/myhat/images/editer/InBlock.gif#执行升级信号

http://blog.51cto.com/myhat/images/editer/InBlock.gif [root@svr2 sbin]# kill -USR2 `cat /usr/local/webserver/nginx/nginx.pid `

http://blog.51cto.com/myhat/images/editer/InBlock.gif

http://blog.51cto.com/myhat/images/editer/InBlock.gif#系统会将nginx.pid进行重命名nginx.pid.oldbin

http://blog.51cto.com/myhat/images/editer/InBlock.gif [root@svr2 sbin]# ll /usr/local/webserver/nginx/
