I have a postgres database called salephone_test
with 3 tables (smartphones, listings, phone_listings
) on my windows pc which I want to replicate to at least one ubuntu droplet on digitalocean. I attempted the following setup to replicate the smartphones table:
On my local machine (pc) in postgresql.conf
I set the listen_addresses = '*'
and wal_level = logical
in pg_hba.conf
, I added the following lines
host salephone_test rep 0.0.0.0/0 md5
host salephone_test all 104.248.54.230/0 md5
host all all 0.0.0.0/0 md5
host all all 0.0.0.0/0 md5
where 104.248.54.230
is the IP of my digitalocean droplet
I also set up a replication user and publication by the following commands
CREATE ROLE rep REPLICATION LOGIN PASSWORD 'fakepass';
GRANT SELECT on smartphones to rep;
CREATE PUBLICATION test_phones FOR TABLE smartphones;
on my remote droplet, after installing postgres on the ubuntu, I created a database called salephone
with a table called smartphones
in psql, I then used the following command to subscribe for logical replication
// 50.71.125.50 is my pc ip according to google
CREATE SUBSCRIPTION phone_sub CONNECTION 'dbname = salephone_test host = 50.71.125.50 user = rep password = fakepass port = 5432' PUBLICATION test_phones;
after a minute of waiting, I received the following
ERROR: could not connect to the publisher: connection to server at "50.71.125.50", port 5432 failed: Connection timed out
Is the server running on that host and accepting TCP/IP connections?
Note: i tried restarting postgres on my pc multiple times already via services.msc

Your home modem/router is surely blocking the connection. You will need to configure it to accept the connection and do 'port forwarding' to your pc. How you do that (or if it is even possible) would depend on the make and model of the router.
Also, your pg_hba doesn't make much sense. The reason to have a more specific entry above a more general entry is to give it a different auth method (or configuration). Since all your entries have the same method, you might as well just have the last line and not have the preceding 3.
