Mac OS X安装Git
一、安装Git由于mac git的地址http://code.google.com/p/git-osx-installer/被墙，被迫使用源码安装，源码可以从http://kernel.org/pub/software/scm/git/下载，编译源码需要先安装xcode，参考http://developer.apple.com。
编译安装
1、解压
tar xjvf git-1.7.4.1.tar.tar.bz2 2. 编译
cd git-1.7.4.1
./configure --prefix=/usr/local
make
3.安装
sudo make install
Ok 了，which git试一下～
二、设置SSH
github使用SSH链接，需要设置SSH
1.检查SSH key
cd ~/.ssh
2.备份已有的key，（如果有的话）
mkdir key_backup
mv id_rsa* key_backup
3.生成SSH key
$ ssh-keygen -t rsa -C jiang.bo.hit@gmail.com
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/jiangbo/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in yes.
Your public key has been saved in id_rsa.pub.
The key fingerprint is:
fb:c4:b0:e0:47:fd:be:e0:fb:ea:73:ef:a8:29:d5:22 jiang.bo.hit@gmail.com
The key's randomart image is:
+--[ RSA 2048]----+
| |
| |
| |
| . |
| . S .. |
| . oE=o.. |
| . +o+.. |
| ..+.+.. |
| oOB=+o |
+-----------------+
4.将SSH key添加到GitHub
登录到GitHub页面，Account Settings->SSH Public Keys->Add another key
将生成的key(id_rsa.pub文件）内容copy到输入框中，save。
5.测试链接
$ ssh git@github.com
The authenticity of host 'github.com (207.97.227.239)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
PTY allocation request failed on channel 0
Hi jiang-bo! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.
别担心，这是正常情况。
三、设置个人信息
$ git config --global user.name "Bo Jiang"
$ git config --global user.email "jiang.bo.hit@gmail.com"
