pg_autoctl create postgres := ERROR Connection to database failed: fe_sendauth: no password supplied

[sacrophyte]

I am not quite sure what I am doing wrong. If you can help me spot the error of my ways, I would very much appreciate it.

"data" is running on port 5432
monitor is on port 5433

I do not understand why pg_autoctl is trying to connect to template1 with a password. Further, I do not understand why the following rule in pg_hba.conf seems (to me) to be ignored:
hostssl all all 0.0.0.0/0 trust

I put the above in temporarily to try to get around the fe_sendauth error to no avail (took it back out).
I tried to use --pg-hba-lan, but that does not seem to help either. Also, I am confused why --pg-hba-lan adds a line for the postgres database, but the error is about template1.

Another very weird thing - running this command ALWAYS stops my "data" cluster. I do not know why.

What am I doing wrong?

Update:
I also tried to specify the name of the database with --dbname postgres , but that did not seem to alter the error.

So, we use template1 to issue the create database statement because we can count on that database existing in Postgres. Then, I see you use ``--pghost urblimsdbdev2a.admin.uillinois.eduand I believe that's where you problem comes from. Please try without using--pghost`, allowing the local connections to use Unix Domain Sockets.

Finally, pg_autoctl is the parent process of Postgres. So when pg_autoctl is not running, Postgres is not running, that's expected.

I removed --pghost and still get the same error.

Yeah well you're still running the command on-top of your misconfigured attempt. It would work if you tried from scratch, I believe, or if you would pg_autoctl drop node --destroy and then try again.

If you want to override the current value for pghost, you could try --pghost localhost or, to use Unix Domain Sockets, the socket directory for your OS. On debian that would be --pghost /var/run/postgresql (and you need permissions, easiest to run as the postgres system user, or as a user that belongs to the postgres group), on RHEL derived systems that would be --pghost /tmp.

[sacrophyte]

My experience with --destroy is that the cluster will be deleted - I do not want that.
I did try to drop the node (sans destroy), but that did not make the problem go away.
I used --pghost /tmp and that did the trick.

If I do not wish to use --pghost localhost (because in the near future the pg host will not be on localhost), what is the correct way to specify --pghost initially? Stick with --pghost urblimsdbdev2a?

Thanks for your help!
