HomeBrew
brew的安裝，直接上官網：http://brew.sh/
一個命令就搞定：
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
PHP7
安裝好brew之后，先安裝php7。安裝php7之前，要先更新一下brew的源並加入一些第三方的庫：
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的包並安裝了
brew search php70
brew install php70
至於php70的擴展安裝，在search的時候就已經有擴展的列表的，按需安裝，安裝也很簡單：
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php7一樣：
brew install nginx
安裝好后，如果要加入到自啟動的話，要先添加一個文件夾：
mkdir -p ~/Library/LaunchAgents
然后把自啟動的plist加入到這個文件夾內：
cp /usr/local/Cellar/nginx/1.10.1/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents
然后執行mac的launchctl命令就可以了：
launchctl -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist
如果把php也加入自啟動的話，也是一樣的吧Cellar/php下面的plist加入到LaunchAgents文件夾下並執行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
安裝一樣簡單：
brew install mysql
安裝好之后，執行mysql.server start
這時候要記得，使用mysql_secure_installration來對mysql進行安全設置，包括設置root密碼以及密碼安全級別等
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
