我一直在关注艺术技术网络服务系列它非常有效地教会我如何在全新的 Ubuntu 12.04 服务器上建立 Nginx 服务器。
然而我遇到了一些问题。
最初通过局域网建立服务器后，转到 192.168.1.10（服务器地址）将获得默认的 Nginx 页面。
一切似乎都按计划进行，只有一点例外，即将 /etc/nginx/sites-available/www 中的尝试文件设置更改为：
location / {
try_files $uri $uri/ =404;
}
未能产生任何变化（当我转到 192.168.1.10 时，我预计默认 Nginx 会更改为 404
我仍继续前行。
现在，似乎有些其他事情出错了，访问 192.168.1.10 只会让我看到一个可怕的无法连接页面：
我想检查一下 Nginx 是否正在运行，因此在服务器上检查了以下内容：
ps -e | grep nginx
令我惊讶的是，这什么也没返回，在它返回之前：
1793 ? 00:00:00 nginx
1794 ? 00:00:00 nginx
1795 ? 00:00:00 nginx
1796 ? 00:00:00 nginx
1797 ? 00:00:00 nginx
我尝试nginx以我的用户身份、使用 sudo 和 root 身份运行。它只是一直告诉我：
nginx: [emerg] "keepalive_timeout" directive is duplicate in /etc/nginx/nginx.conf:26
这意味着它正在运行，不是吗？那么我的工人在哪里？
不确定这是否是导致突然无法连接问题的原因，或者这是否与我在 conf.d 文件或 www sites-available 文件中不可避免地犯的错误有关。
不管怎样，我都不太清楚如何开始排除故障，尝试隔离和诊断问题......而且谷歌搜索“nginx 不再工作”也无济于事......
这是 /etc/nginx/sites-available/www 的转储
