For creating a streaming replication slave from scratch, check out the `pg_basebackup` tool. Exercised right, it will even create a suitable recovery.conf for running a slave instance from the backup it creates. You should also check out Zalando's patroni[0], which is a popular solution for providing automatic failover capabilities for postgres master/slave-pairs. Postgres doesn't support multi-master replication; if you're interested in exploring this anyway, take a look at the BDR project[1].

Hi Arvind,
The log shipping method of standby you are referring to is a warm standby, please have a look at the manuals, and follow it until the section as highlighted below. The URL points to the 9.6 manuals, please change it to 10 for the configuration on PostgreSQL 10.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`
26.2.4. Setting Up a Standby Server
To set up the standby server, restore the base backup taken from primary server (see Section 25.3.4). Create a recovery command file recovery.conf in the standby's cluster data directory, and turn on standby_mode. Set restore_command to a simple command to copy files from the WAL archive. If you plan to have multiple standby servers for high availability purposes, set recovery_target_timeline to latest, to make the standby server follow the timeline change that occurs at failover to another standby.
Note: Do not use pg_standby or similar tools with the built-in standby mode described here. restore_command should return immediately if the file does not exist; the server will retry the command again if necessary. See Section 26.4 for using tools like pg_standby.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`
