mac book 搭建开发环境
（1）安装jdk
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
class_path="$java_home/lib"
path=".:$path:$java_home/bin"
参考：http://www.cnblogs.com/symen/p/4974408.html
（3）安装foxmail
下载地址：http://www.foxmail.com/mac/en/
(3)安装airmail2
airmail2 是一个邮件客户端
（4）配置hosts
参考：http://laod.cn/hosts/2015-google-hosts.html
需要把git的私钥拷贝到 /users/whuanghkl/.ssh 下
(6)运行idea 报错：
error:java: javactask: source release 1.7 requires target release 1.7
解决方法：
进入settings
mac 中使用快捷键 command+逗号
把1.5改为1.7就好了
(7)安装hosts切换工具
mac下 hosts切换工具：gas mask
下载地址：http://www.macupdate.com/app/mac/29949/gas-mask/download
附件也可以下载
(8)安装brew
参考：http://brew.sh/
安装命令：
/usr/bin/ruby -e "$(curl -fssl https://raw.githubusercontent.com/homebrew/install/master/install)"
安装过程：
localhost:downloads whuanghkl$ /usr/bin/ruby -e "$(curl -fssl https://raw.githubusercontent.com/homebrew/install/master/install)"
==> this script will install:
/usr/local/bin/brew
/usr/local/library/...
/usr/local/share/man/man1/brew.1
==> the following directories will be made group writable:
/usr/local/.
/usr/local/bin
==> the following directories will have their owner set to whuanghkl:
==> the following directories will have their group set to admin:
press return to continue or any other key to abort
更新brew
brew update
安装mounty
brew install caskroom/cask/mounty
(9)设置安全级别,方便安装app
有时候安装mac 软件时，提示无法安装或无法打开：
解决方法：设置为anywhere
设置之前，先需要点击
解锁
见附件
(10)安装alfred
参考:http://www.jianshu.com/p/957a45a8b8f2
需要设置alfred两个地方:
(a)设置开机自启动
(b)启动剪切板功能
(11)设置mac 中path环境变量
mac中的命令都会去path中找
注意是大写的path,而不是path,与linux不同.
配置maven的时候就被坑了.
下面是我mac中/etc/profile的配置:
# system-wide .profile for sh(1)
if [ -x /usr/libexec/path_helper ]; then
eval `/usr/libexec/path_helper -s`
fi
if [ "${bash-no}" != "no" ]; then
[ -r /etc/bashrc ] && . /etc/bashrc
java_home=/library/java/javavirtualmachines/jdk1.8.0_77.jdk/contents/home
export java_home
m2_home=/users/admin/software/apache-maven-3.3.9
export m2_home
path=$path:$java_home/bin:$m2_home/bin
export path
alias ll='ls -l'
alias la='ls -a'
alias pd='pwd'
alias cdup='cd ..'
alias cd-='cd -'
nginx -c /usr/local/etc/nginx/nginx.conf
