我可能错过的Nginx常见配置

我最近从 Apache Mod_wsgi 迁移到了 Nginx，我发现速度有了很大的提高，内存使用量也降低了，总体来说我对此非常满意。

我不是服务器专家，所以请温柔一点。

我想知道是否存在我可能错过的小配置，从长远来看这会给我带来一些问题......

请参阅我的nginx.conf文件

user  nginx nginx;

worker_processes  4;

error_log /var/log/nginx/error_log info;

events {
    worker_connections  1024;
    use epoll;

            location / {

                    fastcgi_pass 127.0.0.1:8080;

                    client_max_body_size 100M;
                    }
            access_log      /var/log/nginx/localhost.access_log main;
            error_log       /var/log/nginx/localhost.error_log;
    }
}

我建议你设置较低的 keepalive 超时时间，75 太长而且实际上没用。我通常使用 10-20 秒，这应该足够了。但如果你预计请求不会很多，75 也是可以的。
