(nginx)Apache Forbidden 错误(随机):没有错误日志

(nginx)Apache Forbidden 错误(随机):没有错误日志

我正在运行一个 Nginx 服务器,但最近我随机收到 Apache 的“禁止”错误,而且它似乎在“第一次”访问时从未发生过,只有在刷新/浏览一段时间后才会发生。

更糟糕的是,我“指定”的 httpd 错误日志 (/var/etc/httpd/logs/error_log and /var/logs/httpd/....)是空的。我猜他们应该由于我运行的是 NGINX,所以应该是空的,但错误是由 Apache 显示的,所以我一开始以为它应该在这里。然而我后来得知httpd处于非活动状态。

我指定的 Nginx 日志有效。通过www.example.com(virtual.conf) 访问我的服务器,我看到使用权错误日志。错误日志显示了一些与此问题无关的随机内容。

通过 IP(default.conf)访问我的网站,我获得了访问日志,但错误日志为空。

因此,我认为这个问题不是由 NGINX 引起的,HTTPD 被“禁用”,但是浏览一段时间后,我在任何页面上都会出现随机的“禁止”Apache 错误。

附加信息

我将硬/软 ulimit 都提高到了 166384,重启了服务器,等等。Apache 正在运行由于某种原因(这很奇怪,因为我提到过httpd显示为‘已禁用’)。

Nginx default.conf(通过IP访问服务器的配置)

    server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    access_log  /var/log/nginx/access2.log  main;
    error_log  /var/log/nginx/error2.log warn;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

更新

我现在至少看到了一些错误。以下是审计日志。第一行显示页面加载成功。第二行是我收到“禁止”消息时发生的情况。

type=USER_END msg=audit(1431718801.541:128164): user pid=29115 uid=496 auid=496 ses=9205 msg='op=PAM:session_close acct="nginx" exe="/usr/sbin/crond" hostname=? addr=? terminal=cron res=success'

这是另一种类型的错误:

答案1

这篇文章的目的是告诉你,当你的 ISP 连续三周重复“他们那边一切都好”时,不要相信他们。

我在使用 Putty 时收到此错误。 The server's host key does not match the one PuTTY has cached in the registry.

原来,我的 ISP 的另一个客户不小心将我的 IP 设置为他们自己的 IP,因此有两台机器连接到一个 IP。这也解释了 Apache 错误 - 是另一台服务器给出的错误。
