今天吃完饭回来就在想上午的那个方案虽然可行，但是有个弊端。

就是每上一个新版本，除了上传新版本文件夹之外 还得编辑下 nginx vhost 配置，新增一个虚拟主机。

说麻烦虽然不麻烦 不过也挺烦人的。没有做到自适应，需要人工干预。

所以又折腾了一下。

配置如下：

server {
    listen       80;
    server_name  haha.17ping.cn;
    root         /data/www/sdkHoster;

    location / {
        index    index.php index.htm index.html;
        autoindex on;
    }

    location ~ /([\w\d_]+)/([\w/]*)$ {
        index    index.php index.htm index.html;
        try_files $uri $uri/ /$1/public/index.php?$query_string;
        #return 500 $1;
    }

#    location /sdk1_0 {
#       root    /data/www/sdkHoster;
#       index   index.php index.htm index.html;
#       try_files $uri $uri/ /sdk1_0/public/index.php?$query_string;
#    }

#    location /sdk1_1 {
#       root    /data/www/sdkHoster;
#       index   index.php index.htm index.html;
#       try_files $uri $uri/ /sdk1_1/public/index.php?$query_string;
#    }

    location ~ \.php$ {
        set $newurl $request_uri;
        if ($newurl ~ ^/sdk([\d_]+)(.*)$) {
                set $newurl $2;
        }
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        #fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
        include        fastcgi_params;
        fastcgi_param REQUEST_URI $newurl;
    }

    location ~ \.(css|js|swf|php|htm|html)$ {
        add_header Cache-Control no-store;
    }

    location ~ /\.ht {
        deny  all;
    }
}

保存，重载配置。

手动复制了一份 sdk1_2 目录，重命名为sdk1_2.
访问 http://haha.17ping.cn/sdk1_2/ 成功，美滋滋。
