Installing and configuring Git

This procedure describes how to install and configure Git in order to store all your project data (Jobs, Database connections, Routines, Joblets, data models, processes, stored procedures etc.) in the shared Repository of the Talend Studio.

For more information on the supported Git servers, see Compatible version control systems.

Note: This procedure might not be necessary if the Git server you install already provides Git and you don't need it on your local machine.

Procedure

Download the Git version corresponding to your system at https://git-scm.com/downloads and follow the installation instructions.
Create an SSH key pair in Talend Studio instead of using a Git tool, to ensure the key is compatible with Talend Studio.
1. Open a terminal instance.
2. Generate a new key by using the following command, where email is the email address of the Git server account:
```
ssh-keygen -t ecdsa -b 256 -m PEM -C "email"
```
3. When you are prompted to enter a file in which to save the key, press Enter to accept the default file location, or type a name and press Enter.
4. When you are prompted to enter a passphrase, press Enter to leave it empty.
Put the generated key files in the /home/User_Name/.ssh folder.
Add the generated public key to the settings of your Git server.
1. Use the following command to create a known-hosts file:
  
  ssh-keyscan -H git_server_hostname >> known_hosts
2. Create a config file in your .ssh folder.
3. Add the following content and adapt it to your configuration:
```
Hostname
git_server_hostname IdentityFile  /home/User_Name/.ssh/id_rsa
```
Add the connection information to the Talend Administration Center configuration. For more information, see the Talend Administration Center User Guide.
