In my setup, the configuration file was located at /etc/repmgr/10/nf. Do NOT assume the paths in my example will be the same on your system.

#Aplikasi stok barang sederhana update

If you are using a different version of PostgreSQL you will want to make sure you update the paths for the version you are using. As an example for each server, I updated the node_id, node_name, and conninfo to match the servers I was configuring. Make sure to update each according to the server and paths.

Make sure you install the correct repmgr for the version of PosgreSQL that you are running: yum install -y repmgr10.x86_64Дў) Next, I configured repmgr on each server with the servers specific details. You can find the different yum repositories from : yum install -y ДЎ) I installed repmgr from the PostgreSQL 10 repository.

This repo also includes repmgr, which is where I am installing the software from. With the installation of PostgreSQL 10 on my servers, I installed the PostgreSQL repository using the following RPM. This is an example on base-centos-1: vagrant]# su - postgresДЇor repmgr, I first installed the repmgr software, and then configured it on each server to make sure all of the configurations are correct.

Su - postgres -c 'chmod 600 ~/.ssh/authorized_keys' If you are using SELINUX, make sure it is set up correctly for SSH and authorized keys.ДЎ) Become the Postgres user, create the ssh key, then cat out the public key: su - postgres -c 'ssh-keygen'Дў) Create an authorized keys file and set the permissions: su - postgres -c 'touch ~/.ssh/authorized_keys' This allowed me to SSH between the servers with no prompt. In order to do this I went to each server and generated an SSH key, and then collected all of the public SSH keys and placed them in an authorzied_keys file on each server. In order for repmgr to work correctly, the Postgres user account will need to be able to SSH to each of the other servers with no prompt. Then the fourth and final server will become a witness server used for voting in automatic failover scenarios. The second and third server will become replicas of the primary master. I will configure the first server as the primary master. With PostgreSQL installed on each server, the Postgres user will already be on each server. The environment that I will be working in consists of four CentOS 7 servers with a default install of PostgreSQL 10 installed using yum from the PostgreSQL 10 repo. As an example: su - postgres -c 'COMMAND RUN AS POSTGRES USER'

For the commands that need to be run as the Postgres user, I will run them using su. For reference, all commands are run as root.

This blog post will go over how to set up and implement repmgr which is the PostgreSQL application to manage replication between primary and replica nodes, allowing for quick and easy failover and rebuilding of replicas.
