nginx0.8升级到nginx1.05过程

http://blog.51cto.com/myhat/images/editer/InBlock.gif按照张宴的文档完成了nginx0.8+php5.2.13(fastcgi)+mysql5.5.3的安装，准备将nginx平滑升级。http://blog.51cto.com/myhat/images/editer/InBlock.gif
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 # cp nginx /root/nginx_old
http://blog.51cto.com/myhat/images/editer/InBlock.gif # 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 # 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 # ll /usr/local/webserver/nginx/
