我有个wordpress 站点，是用 lnmp环境搭建的。以前wordpress部署在根目录，直接用域名 www.xxxxx.com 能够访问。 先我想把这个wordpress移动到子目录中去，例如移动到根目录的mse_cn 文件夹下，然后访问通过www.xxxxx.com/mse_cn 首先我把代码都移到了mse_cn 文件夹下，然后修改了nginx的配置：

server {
    listen       80;
    server_name  www.xxxx.com;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

location ^~ /mse_cn {
    root /usr/share/nginx/html;
    index index.php index.html index.htm;
    try_files $uri $uri/ /mse_cn/index.php;

    location ~ \.php {
        fastcgi_split_path_info ^(.*\.php)(.*)$;
        include fastcgi_params;
        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;
        fastcgi_pass 127.0.0.1:9000;
    }
}
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    location ~ /\.ht {
        deny  all;
    }
}

重新加载nginx配置文件，然后我访问 www.xxxxx.com/mse_cn 报404错误，而且页面显示得很奇怪，请求高手帮助！！！
