HomeBrew
brew的安装，直接上官网：http://brew.sh/
一个命令就搞定：
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
PHP7
安装好brew之后，先安装php7。安装php7之前，要先更新一下brew的源并加入一些第三方的库：
brew update
brew tap homebrew/dupes
brew tap homebrew/versions
brew tap homebrew/homebrew-php
然后就可以使用brew搜索php70的包并安装了
brew search php70
brew install php70
至于php70的扩展安装，在search的时候就已经有扩展的列表的，按需安装，安装也很简单：
brew install php70-redis
The php.ini and php-fpm.ini file can be found in: /usr/local/etc/php/7.2/ To have launchd start php now and restart at login: brew services start php Or, if you don't want/need a background service you can just run: php-fpm
Nginx
同php7一样：
brew install nginx
安装好后，如果要加入到自启动的话，要先添加一个文件夹：
mkdir -p ~/Library/LaunchAgents
然后把自启动的plist加入到这个文件夹内：
cp /usr/local/Cellar/nginx/1.10.1/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents
然后执行mac的launchctl命令就可以了：
launchctl -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist
如果把php也加入自启动的话，也是一样的吧Cellar/php下面的plist加入到LaunchAgents文件夹下并执行launchctl命令即可
Docroot is: /usr/local/var/www
The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.
nginx will load all files in /usr/local/etc/nginx/servers/.
To have launchd start nginx now and restart at login:
brew services start nginx
Or, if you don't want/need a background service you can just run:
nginx
Mysql
安装一样简单：
brew install mysql
安装好之后，执行mysql.server start
这时候要记得，使用mysql_secure_installration来对mysql进行安全设置，包括设置root密码以及密码安全级别等
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
MySQL is configured to only allow connections from localhost by default
To connect run:
mysql -uroot
A "/etc/my.cnf" from another install may interfere with a Homebrew-built
server starting up correctly.
To have launchd start mysql now and restart at login:
brew services start mysql
Or, if you don't want/need a background service you can just run:
mysql.server start
