配置nginx别名，帮忙看看哪里错了？

一，不配别名，可以访问

 location ~ /efront/.+\.php  {
            root /hpe/git_root/lms1.0;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            include fastcgi_params;
        }

        location /efront {
            root /hpe/git_root/lms1.0;
            index index.php;
        }

二，配了别名的代码

 location ~ /eft/.+\.php  {
            root /hpe/git_root/lms1.0/efront;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            include fastcgi_params;
        }

        location /eft {
            alias /hpe/git_root/lms1.0/efront;
            index index.php;
        }
