pgBackRest and TLS connections
The TLS server is an alternative to using SSH for protocol connections to remote hosts. It has been pushed in the 2.37 release on 3 Jan 2022.
In this demo setup, the repository host will be called backup-srv and the 3 PostgreSQL nodes in Streaming Replication: pg1-srv, pg2-srv, pg3-srv. All the nodes will be running on Rocky Linux 8.
If you’re familiar with Vagrant, here’s a simple Vagrantfile to initiate 4 virtual machines using those names:
# Vagrantfile
Vagrant.configure(2) do |config|
config.vm.box = 'rockylinux/8'
config.vm.provider 'libvirt' do |lv|
lv.cpus = 1
lv.memory = 1024
end
# share the default vagrant folder
config.vm.synced_folder ".", "/vagrant", type: "nfs"
nodes = 'backup-srv', 'pg1-srv', 'pg2-srv', 'pg3-srv'
nodes.each do |node|
config.vm.define node do |conf|
conf.vm.hostname = node
end
end
end
