Обсуждение: accidentally deleted data directory
Hi
I am new to postgresql. I have postgresql 9.2 installed on Red hat linux 6.4
I accidentally deleted data directory this morning (/var/lib/postgresql/9.2/data)
I tried to start posgresql 9.2 service
service postgresql9.2 start
I got a amessage to initialize the db first.
so I ran service postgresql-9.2 initdb
this was successful
then i tried service postgresql-9.2 start
this failed.
pgstartup.log indicated I can start the database server using:
/usr/pgsql-9.2/bin/postgres -D /var/lib/pgsql/9.2/data
or
/usr/pgsql-9.2/bin/pg_ctl -D /var/lib/pgsql/9.2/data -l logfile start
or
/usr/pgsql-9.2/bin/pg_ctl -D /var/lib/pgsql/9.2/data -l logfile start
However I am unable to start database as root
That is the only account I use on this server.
I tried su - postgres
and then from the bash shell i tried to run these commands (tried one at a time)
but it said address in use
there are no processes running on 5432.
How can I start postgres service?
Thanks
Thara.

See if there are processes running for user "postgres" that look like database processes and kill them. Then try again. What exactly is the error message? Yours, Laurenz Albe
