一，先看一下nginx.conf檔案，如果有下面的一行
include /etc/nginx/sites-enabled/*;
表示配置檔案載入sites-enabled下的檔案。
二，修改/etc/nginx/sites-enabled下的default檔案
內容如下

server {
        listen 80;
        root /usr/share/nginx/html/front-api/public;
        # Add index.php to the list if you are using PHP
        index index.html
 
 index.htm index.nginx-debian.html index.php;
        server_name joe.mafei.com;
        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ /index.php?$query_string;
                //上面這一行，是解析動態網址，如果是需要訪問靜態網址的話，就改成try_files $uri $uri/ =404
 
;
        }
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        #   fastcgi_param  PATH_INFO  $fastcgi_path_info;
 

        #   fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

server {
        listen 80;
        root /usr/share/nginx/html/back-api/public;
        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html index.php;
        server_name back.mafei.com;
        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ /index.php?$query_string;
                //上面這一行，是解析動態網址，如果是需要訪問靜態網址的話，就改成try_files $uri $uri/ =404;
        }
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        #   fastcgi_param  PATH_INFO  $fastcgi_path_info;
        #   fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
}

三，
sudo vi /etc/hosts
新增如下內容

127.0.0.1        joe.mafei.com
127.0.0.1        back.mafei.com

四，重啟nginx sudo /etc/init.d/nginx restart

五，本地，開啟C:\Windows\System32\drivers\etc\hosts
如果無法修改，需要右鍵，屬性，修改其檔案許可權。
修改新增內容如下

    127.0.0.1   128.1.2.41
    127.0.0.1   joe.mafei.com
    127.0.0.1   back.mafei.com

OK了！
