部署上线测试的Node项目,使用nginx反向代理时出现静态资源403错误,本地配置正确,线上同样的配置却产生了错误.配置如下:

upstream nodeblog{
        server 127.0.0.1:3000;
        keepalive 65;
}
server {
        listen 443;
        ssl on;
        server_name ;
        ssl_certificate ;
        ssl_certificate_key ;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers ;
        ssl_session_timeout 5m;
        ssl_prefer_server_ciphers on;
        location / {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $http_host;
                proxy_set_header X-Nginx-Proxy true;
                proxy_set_header Connection '';
                proxy_pass http://nodeblog;
        }
        location ~ .*\.(css|js|jpg|png|gif)$ {
                alias "/root/nodeApp/public/";
                expires 3d;
        }
}

按照提示设置了该目录下所有文件777权限,依旧是403错误
