无法使用第二个站点可用配置重新启动 nginx 服务器

我已在 中设置了一个 nginx 配置，并且运行良好/etc/nginx/sites-available/default-staging。今天，我尝试为基于 的 sendy 电子邮件营销应用程序添加另一个配置此配置。

运行命令失败后service nginx restart我在线检查并发现nginx -c /etc/nginx/sites-available/sendy-newsletter -t应该突出显示任何语法错误，它给出了以下结果。

nginx: [emerg] "server" directive is not allowed here in /etc/nginx/sites-available/sendy-newsletter:1
nginx: configuration file /etc/nginx/sites-available/sendy-newsletter test failed

有两件事让我感到困惑，首先我不明白为什么不允许服务器阻止，在网上查了一下似乎这可能是由于sites-enabled配置文件未包含在hhtp我的块中而导致的nginx.conf，但它们是：

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
    worker_connections 2048;
    multi_accept on;
        use epoll;
}

http {

sites-available其次，当我从和文件夹中删除 sendy-newsletter 配置时sites-enabled，正如预期的那样，我可以成功重启 nginx 服务器，但是奇怪的是当我运行时，nginx -c /etc/nginx/sites-available/default-staging -t我收到与之前相同的错误消息，但是服务器可以工作！？

nginx: [emerg] "server" directive is not allowed here in /etc/nginx/sites-available/default-staging:1
nginx: configuration file /etc/nginx/sites-available/default-staging test failed

这是我的完整配置/etc/nginx/sites-available/sendy-newsletter，它是符号链接的，并且与sites-enabled

    listen 80;
    #listen [::]:80;

    server_name newsletter.example.com;

更新

我检查了我的 nginx 错误日志并在尝试重新启动 nginx 后收到此消息。

2015/11/18 13:09:44 [emerg] 21899#0: bind() to 0.0.0.0:80 failed (98: Address already in use)
2015/11/18 13:09:44 [emerg] 21899#0: bind() to 0.0.0.0:80 failed (98: Address already in use)
2015/11/18 13:09:44 [emerg] 21899#0: bind() to 0.0.0.0:80 failed (98: Address already in use)
2015/11/18 13:09:44 [emerg] 21899#0: bind() to 0.0.0.0:80 failed (98: Address already in use)
2015/11/18 13:09:44 [emerg] 21899#0: bind() to 0.0.0.0:80 failed (98: Address already in use)
2015/11/18 13:09:44 [emerg] 21899#0: still could not bind()

这也是运行的结果：

$ sudo nginx -c /etc/nginx/nginx.conf -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

我还尝试在删除未使用的配置文件后运行语法测试

$ sudo rm default-staging $ sudo rm ../sites-enabled/default-staging $ sudo nginx -c /etc/nginx/sites-available/sendy-newsletter -t nginx：[emerg] /etc/nginx/sites-available/sendy:1 中不允许使用“server”指令 nginx：配置文件 /etc/nginx/sites-available/sendy 测试失败

答案1

当然，你会得到一个错误 :) nginx -c 应该检查你的整个 web 服务器配置，而不仅仅是服务器块。只需在主配置文件上运行它，你就会明白。它会自动考虑任何链接服务器指令。

这就是为什么您应该在进行检查之前从 sites-enabled 目录中删除您不使用的（链接到）指令。您可以随时将其链接回来。

答案2

我真是笨蛋，忘了我在另一款应用程序上运行了 varnish，所以端口 80 被占用了。这就是问题所在，错误日志为我指明了正确的方向，而 nginx -c 却让我感到困惑。
