Git Clone Remote Repository

In this git tutorial, You will learn how to make a clone of remote repository on local system. This will copy all the application files available on remote sever to local system where you can start working.

#1. Generate SSH Key Pair

To connect git server, you may need to configure key based login. So that it will not prompt for each time you connect to the server.

rahul@tecadmin:~$ ssh-keygen

Generating public/private rsa key pair.
Enter file in which to save the key (/home/rahul/.ssh/id_rsa):
Created directory '/home/rahul/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/rahul/.ssh/id_rsa.
Your public key has been saved in /home/rahul/.ssh/id_rsa.pub.
The key fingerprint is:
99:e7:cd:fe:8e:c6:a0:eb:a0:c7:9f:5d:a3:91:b2:00 rahul@tecadmin
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
|                 |
|                 |
|         o       |
|    E   S .      |
|     .   o.+     |
|     .o ..+o=    |
|     .oo.= =oo   |
|    .. o*.o.ooo  |

#2. Copy Public Key to Remote Server

Now copy newly generated public key (~/.ssh/id_rsa.pub) on git server under git account. Use the following command to do it.

rahul@tecadmin:~$ ssh-copy-id -i ~/.ssh/id_rsa.pub git@remote.example.com


/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
git@remote.example.com's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'git@remote.example.com'"
and check to make sure that only the key(s) you wanted were added.

rahul@tecadmin:~$ ssh-copy-id -i ~/.ssh/id_rsa.pub git@remote.example.com

/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys

git@remote.example.com's password:

Number of key(s) added: 1

Now try logging into the machine, with: "ssh '[email protected]'"

and check to make sure that only the key(s) you wanted were added.

#3. Clone Remote Repository on Local

Now use the following command to make a clone of remote git repository on the local system.

rahul@tecadmin:~$ git clone [email protected]:projects/app1.git

Cloning into 'app1'...
warning: You appear to have cloned an empty repository.
Checking connectivity... done.

To verify remote URL in the local copy of code using the following command. In results, you will see two urls one for fetch and one for push operations.

rahul@tecadmin:~/app1$ git remote -v

origin	[email protected]:projects/app1.git (fetch)
origin	[email protected]:projects/app1.git (push)

clone, git, repository
