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在抱怨无法监听我指定的端口，因此服务器无法启动。

我尝试了一些事情：

将配置拆分为sites-available内的多个文件，并创建符号链接到sites-enabled
删除listen属性并允许其回退到默认值
将端口更改为ipv6only=on - 这会导致错误
将端口更改为[::]:80
更改端口以避免冲突，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，说语法正常，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

nginx可能需要一个端口，检查并打开它。它可能会奏效。或者只扫描nginx目录中的所有文件以获取端口98，它必须与nginx配置有关。

nginx - bind（）到0.0.0.0:80失败（98：地址已在使用中）
