Bug #21219
Updated by Alexis Mousset over 2 years ago
*%{color:green}NOTE: A workaround is available in https://issues.rudder.io/issues/21219#note-18%*
Server installs correctly, but relayd refuses to connect:
<pre>
rudder-relayd[15117]: ERROR r2d2: connection to server at "localhost" (127.0.0.1), port 5432 failed: SSL error: i2d ecpkparameters failure
rudder-relayd[15117]: connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL: password authentication failed for user "rudder"
</pre>
and on the postgresql side:
<pre>
rudder@rudder DETAIL: Connection matched pg_hba.conf line 95: "host all rudder 127.0.0.1/32 md5"
rudder@rudder FATAL: password authentication failed for user "rudder"
</pre>
which looks like a standard "wrong password" case (and the matched acl is the right one).
When adding an @sslmode=disable@ the SSL error disappears, but the connection still fails.
<pre>
ERROR r2d2: connection to server at "localhost" (127.0.0.1), port 5432 failed: FATAL: password authentication failed for user "rudder"
</pre>
The connection details look correct:
<pre>
# grep -A3 output.database /opt/rudder/etc/relayd/main.conf
[output.database]
url = "postgresql://rudder@localhost:5432/rudder"
password = "7cb3e8fad6afd0a07efa"
</pre>
<pre>
# grep PSQL /opt/rudder/etc/rudder-passwords.conf
RUDDER_PSQL_PASSWORD:7cb3e8fad6afd0a07efa
</pre>
And connection works with this password:
<pre>
$ psql postgresql://rudder@localhost:5432/rudder?password=7cb3e8fad6afd0a07efa
psql (14.3 (Ubuntu 14.3-0ubuntu0.22.04.1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

This has only been seen on Ubuntu 22.04 for now (with Rudder 7.1.1). This is notably our most recent supported OS (with openssl 3.0 and postgresql 14).
relayd uses the system libpq:
<pre>
# ldd /opt/rudder/bin/rudder-relayd | grep pq
libpq.so.5 => /lib/x86_64-linux-gnu/libpq.so.5 (0x00007fd4513e1000)
</pre>
<pre>
