Hello:
I'm running postgresql 12.9 on Amazon Linux in AWS.
My listen_addresses in postgresql.conf is configured like below:
listen_addresses = '172.17.1.57,localhost'
However, postgresql does not listen on 172..17.1.57. I can reproduce the phenomenon by simply rebooting the server and
thenrun netstat -tulpn
[root@ip-172-17-1-206 data]# netstat -tulpn | grep 5432
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 2605/postgres
And there's nothing abnormal in the logs:
2022-02-09 15:59:36.906 UTC [2663] LOG: database system was shut down at 2022-02-09 15:59:20 UTC
2022-02-09 15:59:36.930 UTC [2605] LOG: database system is ready to accept connections
I had to run:
systemctl restart postgresql
For 172.17.1.57 to listen
[root@ip-172-17-1-206 data]# netstat -tulpn | grep 5432
tcp 0 0 127.0.0.1:5432 0.0.0.0:* LISTEN 4289/postgres
tcp 0 0 172.17.1.57:5432 0.0.0.0:* LISTEN 4289/postgres
Note that 172.17.1.57 is not the primary network interface. I created the network interface and attached it to the EC2
instance.

How do make sure that NIC will be listening every time I started/restarted the server?
Thanks in advance,
