Try directly using:
sudo /etc/init.d/postgresql start
else:
pgrep -u postgres -fa -- -D
How to start Postgres
There again are several ways to start Postgres. If you’re running a Debian-based distribution, you should find the perl wrappers pretty handy.
For Debian or Debian-based (including Ubuntu) Linux distributions
First, issue pg_lsclusters to find out your cluster name:
pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
12 main 5432 online postgres /var/lib/postgresql/12/main /var/log/postgresql/postgresql-12-main.log
To start that particular cluster, you just need to issue:
pg_ctlcluster <Version> <Name> start
So, in our example, it will be:
pg_ctlcluster 12 main start
if that gives an error, use:
sudo /etc/init.d/postgresql start
may need to then run:
584 rake db:drop
586 rake db:create
587 rake db:migrate
588 rake db:seed
