CÀt đặt GIT Server

Trên Client tạo 1 cặp khóa SSH:

thehai@thehai-Vostro-3550:~$ ssh-keygen -C "thehai007@gmail.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/thehai/.ssh/id_rsa):
/home/thehai/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/thehai/.ssh/id_rsa.
Your public key has been saved in /home/thehai/.ssh/id_rsa.pub.
The key fingerprint is:
01:92:be:32:1b:34:41:8d:26:a1:ba:66:9c:95:16:a8 thehai007@gmail.com
The key's randomart image is:
+--[ RSA 2048]----+
|.o.o...          |
|o = o. .         |

Trên Server tạo 1 user git:

useradd git
passwd git

Sau đó tiến hành cài đặt git cho Server:

apt-get install git

Trên server, đăng nhập bằng tài khoản git

su -s /bin/bash - git

Ta sẽ chuyển file id_rsa.pub lên server
Trc tiên ta tạo thư mục .ssh và 1 file authorized_keys bên trong

git@serverwise:/$ mkdir ~/.ssh
git@serverwise:/$ touch ~/.ssh/authorized_keys

Sao chép nội dung trong file id_rsa.pub ở local vào file authorized_keys trên server:

thehai@thehai-Vostro-3550:~$ cat .ssh//id_rsa.pub | ssh root@192.168.1.14 "cat >> /home/git/.ssh/authorized_keys"
root@192.168.1.14's password:

Xem lại thử:

git@serverwise:/$ cat ~/.ssh/authorized_keys

git@serverwise:/$

TRên server tạo folder git repo

git@serverwise:~$ mkdir my-project.git
git@serverwise:~$ cd my-project.git/

Tạo repo ban đầu

git@serverwise:~/my-project.git$ git --bare init
Initialized empty Git repository in /home/git/my-project.git/

Test từ  local:
Tạo 1 project bao gồm 1 số file sau đó đồng bộ lên local:

thehai@thehai-Vostro-3550:~$ mkdir my-project
thehai@thehai-Vostro-3550:~$ cd my-project/
thehai@thehai-Vostro-3550:~/my-project$ git init
Initialized empty Git repository in /home/thehai/my-project/.git/
thehai@thehai-Vostro-3550:~/my-project$ touch readme
thehai@thehai-Vostro-3550:~/my-project$ git add readme
thehai@thehai-Vostro-3550:~/my-project$ git commit -m "commit lan dau"
