安装
目前的项目使用了GIT来进行版本管理，所以学习一下GIT的安装也是应该的了。本文介绍的是编译安装git1.9.0。虽然现在已经到2.6了。
所有命令请在root下进行。
第一步，安装依赖包。
在开始编译安装git之前，首先应该安装好必要的依赖包，省得在安装过程中出现各种问题。

复制代码代码如下:
#yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker

第二步，下载并编译git。
你可以从kernel.org上下载自己需要的版本，或者直接像我这样下载1.9.0版本。
切换到src目录，下载并解压git源码。

复制代码代码如下:
#cd /usr/src
wget https://www.kernel.org/pub/software/scm/git/git-1.9.0.tar.gz
tar xzf git-1.9.0.tar.gz

进入到解压出的git目录，执行编译。

复制代码代码如下:
#cd git-1.9.0
# make prefix=/usr/local/git all
# make prefix=/usr/local/git install
# echo "export PATH=$PATH:/usr/local/git/bin" /etc/bashrc
# source /etc/bashrc

第三步，完成。
现在你已经成功安装好了git，可以执行以下命令查看git版本。

复制代码代码如下:
# git --version

现在的fedora22中已经自带了git2.4以上的版本。

简单配置
我们生成公钥并复制到服务器上：

复制代码代码如下:
[root@test ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
48:3c:22:76:02:f1:a2:e5:27:22:cb:4f:a7:a0:98:9d root@test.com
[root@test ~]# cat .ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAwrmgNAca77BKzXl6BP11fdaclAoWfW+x4kPDZMPj1zFoML9JfOAS7DGY9quLMitwwfg5+U7zP/egPmAhSKCECubmodzMucnRSkJGgKCt1SlctRNDRN3OIvrecAtdZfDcBaWKLjaVzGPmhweLhr6HzfqeZU09Ccis4yK3RMwip2f+K1ZZVIOKUmL4AVFl9dqtxnQ4HlW61PUxvM/ug2M68Z0jQk5DVG8w5+dvGqX1qr5YABD1NX5Jz6aUbVVx7yyoORENxu6SK83GI/V7eOkrvBMDh9nDdwvDhPhuhBDSfE+Xi92hPJPKdNroF1vx8HMvpHME20MmjSwavPrz+B18MQ== root@test.com

下面我们复制id_rsa.pub里的公钥到服务器的authorized_keys文件中。

复制代码代码如下:
[root@git ~]# su git
bash-3.2$ cd
bash-3.2$ vim .ssh/authorized_keys
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAwMU4FKB6NRc3XSoIunWsdvVVuSoncbVb5Al6lB3ciswBVd++YmJFhqwkITNGccrO5sycROs9+Fbjgd6oBSzNuaBtCIbwNNsEyM/henTl2euI3XsnJQ/ITr6c/q0P3WoGl4E2QFQ2kZqs+1eDC0CgHcBrqvFv1Jr414sVYK9lfZwIF+jDdtaBOrSJuq1Agx9pGUFUEB4tQfkXxsWm/MvOmKAVvduKDE1eenUEL9zzyeELPcSXLe3NOoTjZhkX6EEXxQR1ZiZRFywLpfM4qopZ10to2KIUyVtzw6hx6V3cg7kn40lYVW0EAMATw9dVldwcRUI+kJzJSKUTKDVSwY3/+Q== root@CHENMINGQIAN

下面我们clone一个仓库到本地的目录中。

复制代码代码如下:
[root@test ~]# cd /data/dev
[root@test dev]# git clone git@git.jjhh.com:/data/git/project.git

好了，到这里我们的git客户端到这里就全部安装完成了。
