解决Mac nginx问题 [emerg] 54933#0: bind() to 0.0.0.0:80 failed (13: Permission denied)

Posted 2020-10-22 凌乱的博客

brew services restart nginx

Stopping nginx... (might take a while)
==> Successfully stopped nginx (label: homebrew.mxcl.nginx)
==> Successfully started nginx (label: homebrew.mxcl.nginx)

但是实际上没启动成功，查看下错误日志

tail -n 10  /usr/local/var/log/nginx/error.log

查看看端口占用情况：

sudo lsof -i:80

没发现异常，突然想到之前安装过kong,会使用openresty,而openresty 又自带一个nginx，所以先卸载掉（准备使用minikube来运行kong）
但还是不行。

但是把80换成8080端口就可以，最后看到一篇文章（找不到链接了）里的方法搞定：

sudo chown root:wheel /usr/local/Cellar/nginx/1.12.2_1/bin/nginx 
sudo chown root:wheel /usr/local/Cellar/nginx/1.12.2_1/bin/nginx
