Mac OS X安装Git

1、安装Git
因为mac git的地址http://code.google.com/p/git-osx-installer/被墙，被迫使用源码安装，源码能够从http://kernel.org/pub/software/scm/git/下载，编译源码须要先安装xcode，参考http://developer.apple.com。
编译安装
一、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～
2、设置SSH
github使用SSH连接，须要设置SSH
1.检查SSH key
     cd ~/.ssh
2.备份已有的key，（若是有的话）
     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 登陆到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.测试连接 $ 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. 别担忧，这是正常状况。 3、设置我的信息 $ git config --global user.name "Bo Jiang" $ git config --global user.email "jiang.bo.hit@gmail.com"
