Mac使用brew安装nginx，并解决端口80访问权限问题

1、安装

brew install nginx

2、修改配置文件

sudo vi /usr/local/etc/nginx/nginx.conf

修改默认的8080端口为80

修改日志文件地方
    error_log  logs/error.log;

    pid        logs/nginx.pid;

    access_log  logs/access.log;

按上面修改后日志文件在/usr/local/opt/nginx/logs

3、修改管理员权限

sudo chown root:wheel /usr/local/opt/nginx/bin/nginx
sudo chmod u+s /usr/local/opt/nginx/bin/nginx

4、加上launchctl控制

mkdir -p ~/Library/LaunchAgents

cp /usr/local/opt/nginx/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents/

launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist

5、启动nginx

sudo nginx #启动

sudo nginx -t #测试配置文件是否有错

sudo nginx -s reload #重启nginx

6、问题

如果出现nginx: [error] invalid PID number "" in "/usr/local/var/run/nginx/nginx.pid"，则需要
    sudo nginx -c /usr/local/etc/nginx/nginx.conf
    sudo nginx -s reload
