pg_streaming_replication
The module configures and initiates PostgreSQL streaming replication based on replication slots. It is based on tutorial PostgreSQL HA with pgpool-II (or to be more precise on the first three parts of the tutorial).
It is an open source module, published under Apache 2.0 license and managed at Github. Contributors are welcome!
The complete tutorial is available here.
Basic Usage
Assuming that the servers that will participate in replication are:
- 192.168.1.1 (primary)
- 192.168.1.2 (standby)
the primary server can be initialized with something like:
class { 'pg_streaming_replication':
id_rsa_source => 'puppet:///files/my_postgres_ssh_id_rsa',
id_rsa_pub_source => 'puppet:///files/my_postgres_ssh_id_rsa.pub',
nodes => ['192.168.1.1', '192.168.1.2'],
replication_password => 'BDE4CE17-98E5-4FDC-B03C-B94559FE03D8',
initiate_role => 'primary',
}
while the standby server can be initialized with:
class { 'pg_streaming_replication':
id_rsa_source => 'puppet:///files/my_postgres_ssh_id_rsa',
id_rsa_pub_source => 'puppet:///files/my_postgres_ssh_id_rsa.pub',
nodes => ['192.168.1.1', '192.168.1.2'],
replication_password => 'BDE4CE17-98E5-4FDC-B03C-B94559FE03D8',
initiate_role => 'standby',
primary_server_ip => '192.168.1.1',
}
IMPORTANT NOTE: PostgreSQL replication is not a thing that you should configure by simply copying few lines of code. Although with the previous code you'll click-up replication - there's a lot more for you to learn and understand, so I strongly recommend going through the tutorials mentioned above. Even if you are experienced with replication you have to know what pg_streaming_replication module actually does.
