Configuration file for OpenResty PostgreSQL

Configuration file path: /var/postgres12/data/postgresql.conf Access control file path: /var/postgres12/data/pg_hba.conf

When OpenRsty Edge Admin and the database it uses are on the same machine, when OpenRsty Edge Log Server and the database it uses are on the same machine, no additional database configuration is usually required. When OpenRsty Edge Admin and its database are deployed on different machines, the following configuration is required.

Change the following configuration in /var/postgres12/data/postgresql.conf

from

# listen_addresses = 'localhost'

to

listen_addresses = '*'

Next, modify /var/postgres12/data/pg_hba.conf to allow OpenResty Edge Admin access to the database.

host    all     all      10.0.0.1/32             md5

10.0.0.1/32 indicates the range of IP addresses allowed to access the database.

After all, changes have been made, restart the database to make the new configuration take effect:

sudo systemctl restart openresty-postgresql12
