How to Install Barman on Alpine Linux Latest

Barman is a backup and recovery manager for PostgreSQL that provides centralized management of multiple servers. In this tutorial, we will cover how to install Barman on Alpine Linux.

Prerequisites

• A server running Alpine Linux latest
• Root/sudo access to the server

Step 1: Update and Upgrade the System

Before installing Barman, let's update and upgrade the packages installed on the system.

sudo apk update
sudo apk upgrade

Step 2: Install Required Dependencies

Barman requires several dependencies to be installed on your system before running it. We will install them using the following command.

sudo apk add python3-dev libffi-dev openssl-dev gcc musl-dev py3-pip

Step 3: Install Barman

You can install Barman using pip3 package manager.

sudo pip3 install barman

Step 4: Configure PostgreSQL

Barman needs access to your PostgreSQL database, we need to configure PostgreSQL for Barman. Open the pg_hba.conf file and add the following line at the end.

host all barman <ip_address>/32 trust

Replace <ip_address> with the IP address of your Barman server.

Step 5: Configure Barman

In this step, we will configure Barman for our PostgreSQL database.

• Copy the sample Barman configuration file located at /usr/local/lib/python3.8/site-packages/barman/pgbarm.conf.sample to /etc/barman.conf

sudo cp /usr/local/lib/python3.8/site-packages/barman/pgbarm.conf.sample /etc/barman.conf

• Open the Barman configuration file in your text editor

sudo nano /etc/barman.conf

• Update the following lines according to your setup:

[barman]
barman_user = barman
barman_home = /var/lib/barman
backup_directory = /var/lib/barman/%s/backups
compression = gzip
minimum_redundancy = 1
retention_policy = RECOVERY WINDOW OF 30 DAYS

• Save and close the file.

Step 6: Add PostgreSQL server to Barman

In this step, we will add our PostgreSQL database server to Barman.

• Create a new file pg1.conf in the /etc/barman.d directory.

sudo nano /etc/barman.d/pg1.conf

• Add the following configuration

[pg1]
description = "Production PostgreSQL server"
conninfo = host=<ip_address> user=<user> dbname=<dbname> password=<password>
backup_method = postgres
streaming_archiver = on

Replace <ip_address>, <user>, <dbname>, and <password> with your PostgreSQL server details.

• Save and close the file.

Step 7: Backup PostgreSQL server

In this step, we will take a backup of our PostgreSQL server using Barman.

sudo barman backup pg1

This command will create a new backup of the PostgreSQL server and save it in the Barman server's default backup directory.

Conclusion

Congratulations! You have successfully installed and configured Barman on Alpine Linux latest. You can now use it to manage your backups and recover PostgreSQL databases in case of any disaster or data loss.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
