Обсуждение: [ADMIN] pgdg96 repo with centos 7.x - server starts only on loopback
hi fellas I'm using PostgreSQL 9.6 7 - x86_64 repo with centos 7.3. Configuration pretty standard, including this among the lines: ... listen_addresses = 'localhost, 192.168.2.200, 10.5.6.100' ... and yet, after system reboot I get process listening only on: tcp 0 0 127.0.0.1:15432 0.0.0.0:* LISTEN 5373/postmaster tcp6 0 0 ::1:15432 :::* LISTEN 5373/postmaster all I have to do is to: $ systemctl restart postgresql-9.6 to get expected results. Is this not bizarre? I peep into systemd's Unit and there: ... [Unit] Description=PostgreSQL 9.6 database server After=syslog.target After=network.target seems ok, right? What can be wrong? many thank L.

Looking into the postmaster's log would be informative, but I suspect what is happening is that systemd is allowing the postmaster to start before those non-default interfaces are up. This is one of the ways systemd sucks :-( ... it's actually quite hard to prevent that. "After=network.target" does *not* do it, at least not without munging the definition of that target. I don't offhand recall the solution for this, but it's a systemd question not a Postgres question. Googling on that basis might help. regards, tom lane
Is SELINUX on?

Looking into the postmaster's log would be informative, but I suspect
what is happening is that systemd is allowing the postmaster to start
before those non-default interfaces are up. This is one of the ways
systemd sucks :-( ... it's actually quite hard to prevent that.
"After=network.target" does *not* do it, at least not without munging
the definition of that target.
I don't offhand recall the solution for this, but it's a systemd
question not a Postgres question. Googling on that basis might help.
