How to Install Barman on Elementary OS Latest

Barman is an open-source tool for managing PostgreSQL backups, which can be used to simplify backup and recovery processes. Here's how to install Barman on the latest version of Elementary OS:

Prerequisites

Before you begin installing Barman, you need to ensure that your system meets the following prerequisites:

• You have the latest version of Elementary OS installed on your system.
• You have root access or sudo permissions on the system.
• You have PostgreSQL installed and properly configured.

Step 1: Install Dependencies

First, you need to install the necessary packages and dependencies. Open the terminal and run the following command:

sudo apt-get install -y python-pip python-dev libpq-dev sshpass

This will install the required packages for Python, Postgres, and SSH support.

Step 2: Install Barman

Once you have installed the dependencies, you can install Barman using the following command:

sudo pip install pgbarman

This command will download and install Barman on your system.

Step 3: Verify Installation

After the installation is complete, you can verify the installation by running the following command:

barman --version

This command will display the version of Barman that you have installed.

Step 4: Configure Barman

Before you can start using Barman, you need to configure it. You can do this by creating a barman.conf file in the /etc/barman.d/ directory. You can use the following command to create the file and edit it:

sudo nano /etc/barman.d/barman.conf

In this file, you need to add the following details:

[barman]
barman_user = <barman_username>
barman_password = <barman_password>
backup_directory = /var/lib/barman/%(server_name)s

Replace <barman_username> and <barman_password> with the username and password you want to use for Barman. Also, ensure that the backup_directory is set to the proper path.

Save the file and exit the editor.

Step 5: Configure SSH

To enable Barman to connect to the PostgreSQL server, you need to configure SSH. You can do this by adding the following details to the /etc/barman.d/pg.conf file:

[streaming]
enabled = 1
method = ssh
ssh_command = ssh postgres@<postgres_server_ip> -p 22
rsync_options = -p --chmod=go-w
streaming_conninfo = host=<postgres_server_ip> user=barman dbname=postgres

Replace <postgres_server_ip> with the IP address of your PostgreSQL server.

Save the file and exit the editor.

Step 6: Start Barman

To start using Barman, you can run the following command:

sudo systemctl start barman

This will start the Barman service.

Conclusion

That's it! You have now installed and configured Barman on your Elementary OS system. You can now use Barman to manage your PostgreSQL backups.
