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
drwxrwxr-x  git git   Nov  : .
drwx------  git git    Nov  : ..
drwxrwxr-x  git git     Nov  : branches
-rw-rw-r--  git git    Nov  : config
-rw-rw-r--  git git    Nov  : description
-rw-rw-r--  git git    Nov  : HEAD
drwxrwxr-x  git git  Nov  : hooks
drwxrwxr-x  git git    Nov  : info
drwxrwxr-x  git git    Nov  : objects
drwxrwxr-x  git git    Nov  : 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
drwxr-xr-x  root root   Nov  : .
drwxr-xr-x  root root    Nov  : ..
drwxr-xr-x  root root     Nov  : branches
-rw-r--r--  root root   Nov  : config
-rw-r--r--  root root    Nov  : description
-rw-r--r--  root root    Nov  : HEAD
drwxr-xr-x  root root  Nov  : hooks
drwxr-xr-x  root root    Nov  : info
drwxr-xr-x  root root    Nov  : objects
drwxr-xr-x  root root    Nov  : 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
  file changed,  insertion(+)
 create mode  index.html

# git push origin master
