To get started you need two machines that are the same architecture, ie 64 bit, with the same version of Postgres installed, including same Postgres architecture.
1. On Master – In pgAdmin run:
CREATE USER replicator REPLICATION LOGIN ENCRYPTED PASSWORD 'mypassword';
2. On Master – In pgAdmin, edit the postgresql.conf and set the following:
wal_level = hot_standby max_wal_senders = 3 checkpoint_segments = 8 wal_keep_segments = 8
3. On Master – In pgAdmin, edit the pg_hba.conf and set the following where 220.127.116.11 is the ip address of the slave:
host replication replicator 18.104.22.168/32 trust
4. On Master – restart the postgres windows service
5. On Slave – stop the postgres windows service
6. On Slave – open a command prompt and cd to your Postgres directory (c:\program files\Postgresql\9.4) and run:
rd /s “c:\program files\Postgresql\9.4\data”
7. On Slave – open a command prompt and cd to your Postgres directory (c:\program files\Postgresql\9.4) and run where 22.214.171.124 is the ip of the Master:
pg_basebackup -h 126.96.36.199 -D “c:\program files\Postgresql\9.4\data” -U replicator -v –P –X stream
8. On slave – In pgAdmin, edit the postgresql.conf and set the following:
hot_standby = on
9. On slave – create a text file (c:\program files\Postgresql\9.4\data\recovery.conf) with the following contents where 188.8.131.52 is the ip of the Master:
standby_mode = 'on'primary_conninfo = 'host=184.108.40.206 port=5432 user=replicator password=mypassword'trigger_file = 'c:\temp\postgresql.trigger'
10. On Slave – start the postgres windows service
Master and Slave should now be in sync. Update Master DB and confirm that the Slave is updated as well.
