宝塔虽然支持一键反向代理，
但是经过尝试，总是不好用

干脆手动配置，直接修改配置文件
把配置文件里面的下面内容进行替换

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
        error_log off;
        access_log /dev/null;
    }
    
    location ~ .*\.(js|css)?$
    {
        expires      12h;
        error_log off;
        access_log /dev/null; 
    }

替换成下面的

    location / 
    {
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://127.0.0.1:8181;
    }

    location ~ .*\.(php|jsp|cgi|asp|aspx|flv|swf|xml)?$
    {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_pass http://127.0.0.1:8181;
    
    }
