Обсуждение: run copy of database on another (backup) server
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, -- Marchello Lippi
Fixed using stopped postgres chown postgres:postgres /var/lib/postgresql/9.3/main -R chmod 0700 /var/lib/postgresql/9.3/main -R started postgres Regards, -- Marchello Lippi Marchello Lippi wrote: > 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.
