Excuse me for my mediocre knowledge in Ubuntu and Postgresql. I have a VPS with Ubuntu 14.04.5 LTS (GNU/Linux 2.6.32-042stab127.2 x86_64) and also have Postgresql installed. I'm using Postgresql in a ruby on rails application. As soon as I rebooted the ubuntu with
$sudo reboot
Suddenly my application and Postgresql Database stopped running throwing the error
could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
$ sudo -i -u postgres
$ psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
$psql -V
psql (PostgreSQL) 11.0 (Ubuntu 11.0-1.pgdg14.04+2)
$pg_config --version
PostgreSQL 11.0 (Ubuntu 11.0-1.pgdg14.04+2)
$postgres -V
The program 'postgres' is currently not installed. You can install it by typing:
apt-get install postgres-xc
$locate bin/postgres
/usr/lib/postgresql/11/bin/postgres
/usr/lib/postgresql/9.3/bin/postgres
/usr/lib/postgresql/9.4/bin/postgres
/usr/lib/postgresql/9.5/bin/postgres
$/usr/lib/postgresql/11/bin/postgres -V
postgres (PostgreSQL) 11.0 (Ubuntu 11.0-1.pgdg14.04+2)
$pg_lsclusters
9.3 main 5432 down postgres /var/lib/postgresql/9.3/main /var/log/postgresql/postgresql-9.3-main.log
11 main 5433 down postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
The postgres status is down
$service postgresql status
9.3/main (port 5432): down
11/main (port 5433): down
$systemctl status postgresql.service
postgresql.service

$systemctl status [email protected]

$grep -H '^port' /etc/postgresql/*/main/postgresql.conf /etc/postgresql/11/main/postgresql.conf:port = 5433
/etc/postgresql/9.3/main/postgresql.conf:port = 5432
I am trying to start Postgresql 9.3 with
$service postgresql start 9.3
* Starting PostgreSQL 9.3 database server
* Failed to issue method call: Unit [email protected] failed
to load: No such file or directory. See system logs and 'systemctl

$sudo systemctl start postgresql
