ubuntu - nginx - 绑定(bind)()到 0.0.0.0 :80 failed (98: Address already in use)

Question

我有一个设置了 5 个服务器配置的反向代理，但是从一开始它就一直提示无法监听我指定的端口，因此服务器无法启动。

我已经尝试了一些事情:

• 将配置拆分为 sites-available 中的多个文件，并创建指向 sites-enabled 的符号链接(symbolic link)
• 删除 listen 属性并允许其回退到默认值
• 将端口更改为 ipv6only=on - 这导致了错误
• 将端口更改为 [::]:80
• 更改端口以免发生冲突，即 80、81、82 等。

使用 netstat 我可以看到我需要的端口上没有运行任何东西，当我运行 nginx -t 时我得到一个成功的输出，说 syntax is ok and nginx .conf 测试成功。

这是我的 nginx 输出:

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:81 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:82 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:83 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:84 failed (98: Address already in use)

有人知道这是为什么造成的吗？提前致谢

这是我的服务器配置:

可能有nginx需要的端口，检查并打开它。它可能会起作用。或者只是扫描 nginx 目录中的所有文件以查找端口 98 它必须与 nginx 配置有关。
