How to do it...
These steps will assume that we've installed PgBouncer on pgha-proxy, the same node as our HAProxy service. Follow these instructions to tightly couple PgBouncer and HAProxy:
- Alter the haproxy.cfg file so that the ft_postgresql section resembles the following:
frontend ft_postgresql
bind *:5433
default_backend bk_db
- Modify the [databases] section in the pgbouncer.ini file and ensure that it contains the following line:
* = host=pgha-proxy port=5433
- Modify the [pgbouncer] section in the pgbouncer.ini file and change the following entry:
listen_port = 5432
- Restart the HAProxy and PgBouncer services in the following order:
sudo systemctl restart haproxy sudo systemctl restart pgbouncer
