我可能錯過的 Nginx 常用配置

Question

我最近從 Apache Mod_wsgi 遷移到 Nginx，我發現速度有了重大改進，記憶體使用量降低了，我對此非常滿意。

我不是伺服器專家，所以請溫柔。

我想知道是否有任何我可能錯過的小配置，從長遠來看這會給我帶來一些問題...

請看我的nginx.conf文件

user  nginx nginx;

worker_processes  4;

error_log /var/log/nginx/error_log info;

events {
    worker_connections  1024;
    use epoll;
}

http {
    include         /etc/nginx/mime.types;
    default_type    application/octet-stream;

    log_format main
            '$remote_addr - $remote_user [$time_local] '
            '"$request" $status $bytes_sent '
            '"$http_referer" "$http_user_agent" '
            '"$gzip_ratio"';

    client_header_timeout   10m;
    client_body_timeout     10m;
    send_timeout            10m;

    client_header_buffer_size       1k;
    large_client_header_buffers     4 2k;
    request_pool_size               4k;

    gzip on;
    gzip_min_length 1100;
    gzip_buffers    4 8k;
    gzip_types      text/plain;

    output_buffers  1 32k;

            server_name localhost;
            location /media/  {
                    root /www/django_test1/myapp; # Notice this is the /media folder that we create above
            }

            }
            location / {
                    # host and port to fastcgi server
                    fastcgi_pass 127.0.0.1:8080;
                    fastcgi_param  SERVER_ADDR        $server_addr;
                    fastcgi_param  SERVER_PORT        $server_port;
                    fastcgi_param  SERVER_NAME        $server_name;
                    fastcgi_param  SERVER_PROTOCOL    $server_protocol;

                    fastcgi_param  CONTENT_LENGTH     $content_length;
                    fastcgi_pass_header Authorization;
                    fastcgi_intercept_errors off;
                    client_max_body_size 100M;
                    }
            access_log      /var/log/nginx/localhost.access_log main;
            error_log       /var/log/nginx/localhost.error_log;
    }
}

我建議你設定較低的 keepalive 超時時間，75 太多了而且幾乎沒有用。我通常用10-20秒，應該夠了。但如果您預計請求不多，75 也可以。
