git仓库的安装和基本使用

一、安装git软件

# yum install git -y

二、初始化git仓库

2.1 在git仓库的机器进行配置

# ifconfig eth0 | awk -F '[ :]+' 'NR==2 {print $3}'
 192.168.5.71

# useradd git              # 创建用户
# passwd git               # 为git用户设置密码
# su - git                 # 切换用户
$ mkdir www.git
$ cd www.git/
$ git --bare init          # 初始化远程仓库
Initialized empty Git repository in /home/git/www.git/
$ ll -a
total 16
drwxrwxr-x 7 git git  111 Nov 14 15:14 .
drwx------ 3 git git   73 Nov 14 15:14 ..
drwxrwxr-x 2 git git    6 Nov 14 15:14 branches
-rw-rw-r-- 1 git git   66 Nov 14 15:14 config
-rw-rw-r-- 1 git git   73 Nov 14 15:14 description
-rw-rw-r-- 1 git git   23 Nov 14 15:14 HEAD
drwxrwxr-x 2 git git 4096 Nov 14 15:14 hooks
drwxrwxr-x 2 git git   20 Nov 14 15:14 info
drwxrwxr-x 4 git git   28 Nov 14 15:14 objects
drwxrwxr-x 4 git git   29 Nov 14 15:14 refs

2.2 在远程机器中拉取代码（另一台机器操作）

# ifconfig eth0 | awk -F '[ :]+' 'NR==2 {print $3}'
192.168.5.72

# mkdir test
# cd test/
# git clone git@192.168.5.71:/home/git/www.git           # 输入上面创建的git的用户密码
Cloning into 'www'...
git@192.168.5.71's password: 
warning: You appear to have cloned an empty repository.

# ll -a www/.git/
total 16
drwxr-xr-x 7 root root  111 Nov 14 15:16 .
drwxr-xr-x 3 root root   17 Nov 14 15:16 ..
drwxr-xr-x 2 root root    6 Nov 14 15:16 branches
-rw-r--r-- 1 root root  259 Nov 14 15:16 config
-rw-r--r-- 1 root root   73 Nov 14 15:16 description
-rw-r--r-- 1 root root   23 Nov 14 15:16 HEAD
drwxr-xr-x 2 root root 4096 Nov 14 15:16 hooks
drwxr-xr-x 2 root root   20 Nov 14 15:16 info
drwxr-xr-x 4 root root   28 Nov 14 15:16 objects
drwxr-xr-x 4 root root   29 Nov 14 15:16 refs

三、免密钥拉取代码

3.1 在远端要拉取代码的机器创建公钥，并将公钥放入git机器中

# ssh-keygen -t rsa
# ssh-copy-id -i /root/.ssh/id_rsa.pub git@192.168.5.71

3.2 进行免密拉取代码

# git clone git@192.168.5.71:/root/git/www.git
Cloning into 'www'...
warning: You appear to have cloned an empty repository.

3.3 免密push代码文件

# git clone git@192.168.5.71:/home/git/www.git
Cloning into 'www'...
warning: You appear to have cloned an empty repository.

# cd www/
# echo 'sleep' > index.html
# git add .

# git commit -m 'add index.html file'
[master (root-commit) b629ad0] add index.html file
 1 file changed, 1 insertion(+)
 create mode 100644 index.html

# git push origin master
