This section will provide explanations for the offline installation of PostgreSQL 10 on Linux – including replication configuration with automatic failover (using REPMGR).
Please make sure you have the “HA DB” file which contains all the necessary RPMs.

For this first step of the procedure, we will use two DB servers, one as the Master and the second as Slave.
