yum update nginx

执行命令前，首先配置nginx 源

[html] view plaincopy

 

1. [root@localhost ~]# vim /etc/yum.repos.d/nginx.repo  

[html] view plaincopy

 

1. #nginx.repo  
2.   
3. [nginx]  
4. name=nginx repo  
5. baseurl=http://nginx.org/packages/centos/6/$basearch/  
6. gpgcheck=0  
7. enabled=1  

yum update nginx 

nginx -v  查看当前nginx版本

        include fastcgi_params;

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

nginx版本不一致时，有可以会更改fastcgi-php.conf文件为fastcgi_params
