nginx 做反向代理，到当前服务器的其他端口，有时候能访问，刷新一下就不行了

server { listen 80 default_server reuseport; #listen [::]:80 default_server ipv6only=on; server_name _; index index.html index.htm index.php; root /home/wwwroot/default;

    #error_page   404   /404.html;

    # Deny access to PHP files in specific directory
    #location ~ /(wp-content|uploads|wp-includes|images)/.*\.php$ { deny all; }

    include enable-php.conf;
    location /nginx_status
    {
        stub_status on;
        access_log   off;
    }

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
        expires      12h;
    }
