Mac使用brew安裝nginx，並解決端口訪問權限問題

一、安裝

brew install nginx

二、修改配置文件

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

修改默認的8080端口爲80

修改日誌文件地方
    error_log  logs/error.log;

    pid        logs/nginx.pid;

    access_log  logs/access.log;

按上面修改後日誌文件在/usr/local/opt/nginx/logs

三、修改管理員權限

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

四、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

五、啓動nginx

sudo nginx #啓動

sudo nginx -t #測試配置文件是否有錯

sudo nginx -s reload #重啓nginx

六、問題

若是出現nginx: [error] invalid PID number "" in "/usr/local/var/run/nginx/nginx.pid"，則須要
    sudo nginx -c /usr/local/etc/nginx/nginx.conf
    sudo nginx -s reload
