mac book 搭建开发环境

mac book 搭建开发环境
（1）安装jdk
mac jdk 下载地址：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
注意：要下载jdk，而不是jre
（2）设置java环境变量
mac booke中安装jdk ，没有让用户选择安装目录，那么jdk安装到了哪里呢？
默认安装到了：

/Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk
所以设置JAVA_HOME
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home

export JAVA_HOME
参考：http://www.cnblogs.com/symen/p/4974408.html

（3）配置hosts
参考：http://laod.cn/hosts/2015-google-hosts.html
(4)设置git权限
需要把git的私钥拷贝到 /Users/whuanghkl/.ssh 下

使用git私钥

** (5)安装hosts切换工具**
mac下 hosts切换工具：gas mask

切换hosts
