启动 Nginx 报错：nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
原因是端口 8080 被使用了，需要换个端口，或者停用掉之前的 8080 端口在重新启用服务器。

Mac 系统

方式一：Nginx 将占用的端口换成别的端口
方式二：通过命令查看是什么程序占用 8080 端口

$ sudo lsof -i tcp:8080

输出发现有 Google、QQ、node 占用着 8080 端口。

如果不是什么特殊的程序，直接通过命令移除一下

$ sudo kill PID
例如：
$ sudo kill 391
也可以同时清理多个PID：
$ sudo kill 391 722 4074

移除之后在运行 $ nginx 再次启动，如果有特殊软件或者不知道该不该关，那就 nginx 先换个端口用也一样。
