Hi all,
I tried to run copy of my database on another server.
Found its path using
Code:
SHOW data_directory
it is /var/lib/postgresql/9.3/main
Put it into tar.gz archive using sudo on main server, copied archive into
backup server, stopped postgresql on backup server, extracted archive into
/var/lib/postgresql/9.3/main2 directory, changed data_directory path in
/etc/postgresql/9.3/main/postgresql.conf, tried to start postgresql on
backup server, but got error:
$ sudo service postgresql start
* Starting PostgreSQL 9.3 database server
* Error: could not exec /usr/lib/postgresql/9.3/bin/pg_ctl
/usr/lib/postgresql/9.3/bin/pg_ctl start -D /var/lib/postgresql/9.3/main2
-l /var/log/postgresql/postgresql-9.3-main.log -s -o -c
config_file="/etc/postgresql/9.3/main/postgresql.conf" :
[fail]
Tried to put files into default directory and changed back path in conf
file, then tried to start postgresql on backup server, got error again:
$ sudo service postgresql start
* Starting PostgreSQL 9.3 database server
* Error: could not exec /usr/lib/postgresql/9.3/bin/pg_ctl
/usr/lib/postgresql/9.3/bin/pg_ctl start -D /var/lib/postgresql/9.3/main
-l /var/log/postgresql/postgresql-9.3-main.log -s -o -c
config_file="/etc/postgresql/9.3/main/postgresql.conf" :
[fail]
How do I solve it?
I suppose, I should change rights after extracting files from archive
under sudo, but don't know what exactly to change.
versions (on both main and backup servers)
Ubuntu 14.04.5 LTS
Postgresql 9.3
Please advise.
Thanks ahead.
Regards,
