Обсуждение: postgresql doesn't start
hi there,
I've a big problem with my postgresql installation
I've postgresql 9.3 installed on docker; I start it via supervisord
I've never had issues with postgresql and I don't touched nothing (no update, no changes)
this is my configuration
there's a file called postgresql.conf in /etc/supervisor/conf.d/
cat command:
[program:postgres]
command=/opt/postgresql.sh
autostart=true
autorestart=true
stopsignal=QUIT
lookt at /opt/postgresql.sh
#!/bin/sh
# This script is run by Supervisor to start PostgreSQL 9.3 in foreground mode
if [ -d /var/run/postgresql ]; then
chmod 2775 /var/run/postgresql
else
install -d -m 2775 -o postgres -g postgres /var/run/postgresql
fi
exec su postgres -c "/usr/lib/postgresql/9.3/bin/postgres -D /var/lib/postgresql/9.3/main -c config_file=/etc/postgresql/9.3/main/postgresql.conf"
until yesterday there were no problem
right now I see this in the /var/log/supervisor's directory:
2015-10-01 21:40:18 UTC HINT: The file seems accidentally left over, but it could not be removed. Please remove the file by hand and try again.
2015-10-01 21:40:20 UTC FATAL: could not remove old lock file "postmaster.pid": Permission denied
if I remove this file with sudo permissions when I re-run the process I've the same error and I don't understand why. I tried the same configuration (postgresql installation and configuration) in another new docker installation and works fine.
what's the problem?
someone help me?
I've very important databases and I dont' know how to recover it
please let me know, thanks in advance

Looks like something removed the postmaster's write permission on
the data directory itself.

The directory . should be owned by the postgres user, and it should have
700, 750, or 770 permissions. all the files in it should also be owned
by postgres.
also look and see if postgres logged anything in its own system log
files (/var/log/postgresql/9.3 or whatever).

Are you using docker on centos ? I had problem with centos/docker/postgresql because container size was (maybe still is) limited to 20GB on that specific OS. Maybe not related, but good to know

Adrian,
thanks a lot
about your questions
1. postgresql was installed via apt-get install postgresql -y command
2. in /var/run/postgresql/ there is only one file called 9.3-main.pid
3. postgres is not running, I did not find nothing with ps command
4. I remove the postmaster.pid file and I tried to run postgresql manually. this is the result:
# /etc/init.d/postgresql start
* Starting PostgreSQL 9.3 database server
The PostgreSQL server failed to start. Please check the log output.
...fail!
I verified in /var/log/postgresql/ and I've not found nothing

is there a way to recover all dbs without starting the daemon?
How was Postgres installed?
So there is a pid file present in the data directory, how about in the run directory, /var/run/postgresql?
Is Postgres running? so:
ps ax|grep post
or
pg_ctl status -D /var/lib/postgresql/9.3/main
If not what happens if you remove the pid and start Postgres manually, not through supervisor?because I've another one docker with the same configuration and works
fine (same os, same versione of postgresql)

The directory . should be owned by the postgres user, and it
should have 700, 750, or 770 permissions. all the files in it

also look and see if postgres logged anything in its own system
