postgres, ubuntu how to restart service on startup? get stuck on clustering after instance reboot

Question

I have a Postgres db 9.1 running on AWS EC2, with ubuntu 12.04.

I messed a lot with the instance (i.e installed all kinds of postgres X.X before i settled on 9.1).

Now after a month working on that db, I discovered that if I restart my instance postgres doesn't load correctly, its status says "Running clusters". this will last forever until I

sudo service postgresql restart

from terminal, and then it works again.

How do I add this line, to ubuntu startup so that each time it loads, it will restart this service, and hopefully solve my problem?

Also any other solution which might solve this.

Solution 1

I guess it would be best to fix the database startup script itself. But as a work around, you can add that line to /etc/rc.local, which is executed about last in init phase.

Solution 2

On Ubuntu 18.04:

sudo systemctl restart postgresql.service

Solution 3

The below command worked for me

sudo service postgresql restart

Solution 4

ENABLE is what you are looking for

USAGE: type this command once and then you are good to go. Your service will start automaticaly at boot up

 sudo systemctl enable postgresql

DISABLE exists as well ofc

Some DOC: freedesktop man systemctl

Solution 5

restart postgresql

$ sudo service postgresql restart

If you came here by google (like me) looking for the command to restart postgresql, in my case it was service postgresql-9.3 restart

Came just to get that restart command, got what I want, thanks

thanks, but either that rc.local is not running, or the command executed before whatever postgres is doing, or the db overrides it somehow, il look into the logs for info, but off the bat that does not work.

Maybe there is a race condition, so rc.local gets executed before the regular postgres start process is finished, probably due to the error. Maybe you can add a sleep before the restart and see if that is a valid work around.

thanks the rc was the right directions, i found the solution in the rcX files. which govern the startup order

[Rajan Verma - Aarvy]

You need to provide the cluster version as well: sudo systemctl start postgresql-9.5.service

@Aarvy strangely, on Ubuntu 20 with Postrges 13, the version isn't needed for systemctl

maybe i think this is for enable....
