- 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。
