Thank you very much.
I did these additional cmds and all worked fine!
cd /etc/rc.d/init.d
ln postgresql-9.6 pgsat
cd /etc/sysconfig/pgsql
echo "PGDATA=/sistemas/sat4/bdpg" > pgsat
service pgsat start
chkconfig --add pgsat
chkconfig pgsat on
chkconfig postgresql-9.6 off

Re: [GENERAL] Problem changing default data_directory in PG 9.6 + CentOS6

2016-10-18 Thread Edilmar LISTAS 

Hi,

After some tests, really the problem is with original script from PG 9.6 
RPM /etc/rc.d/init.d/postgresql-9.6. If I run pg_ctl, start/stop with 
the new data_directory works fine!

So /var/lib/pgsql/9.6/data is where the original install is?

Best guess is that some script is starting the original install
and when
you go to start your custom location it fails because the new
cluster is
trying to use the port(5432 I am assuming) as the original
cluster.

Have you tried giving the new cluster a different port number,
say 5442,
and the starting it?


(and the children logger/checkpointer/etc). But I don't get
to connect
using pgAdmin3. Then, I have to kill manually postmaster
(because
service script doesn't understand postmaster.pid in the new
data dir),
comment data_directory to use default place, start and
connect to
pgAdmin3. Then, start/stop/start/etc run fine lookup for
postmaster.pid
in /var/lib/pgsql/9.6/data.


So you either need to change the start script to point to the new
cluster or create a new one for it.

What is the value of data_directory in postgresql.conf ?

Is there anything in /var/log/postgresql/{log_filename}   ... where
{log_file} is the value set in postgresql.conf ?

[GENERAL] Problem changing default data_directory in PG 9.6 + CentOS6

2016-10-17 Thread Edilmar LISTAS 

  
  
I have an env running a changed data_directory fine in a devel
machine PG 9.4 using Fedora23. 
Now, I have a server machine with CentOS where I downloaded the RPMs
from repo https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-centos96-9.6-3.noarch.rpm.
All the configs run fine if I doesn't change the default
data_directory. But I need to use the path /sistemas/sat4/bdpg.

I did these commands:

mkdir /sistemas/sat4/bdpg
chown postgres /sistemas/sat4/bdpg
chmod 700 /sistemas/sat4/bdpg
su - postgres 
/usr/pgsql-9.6/bin/initdb -D /sistemas/sat4/bdpg
exit

Then, I changed data_directory to /sistemas/sat4/bdpg and tried to
restart PG:
service postgresql-9.6 restart
STOP => OK
START => FAILED

I disabled se_linux.
The file /var/lib/pgsql/9.6/pgstartup.log just said to see future
output in pg_log.
The file data/pg_log/postgresql-Mon.log doesn't say anything about
errors.

The strange is that startup arises a FAILED message, but the process
"/usr/pgsql-9.6/bin/postmaster -D /var/lib/pgsql/9.6/data" is
running (and the children logger/checkpointer/etc). But I don't get
to connect using pgAdmin3. Then, I have to kill manually postmaster
(because service script doesn't understand postmaster.pid in the new
data dir), comment data_directory to use default place, start and
connect to pgAdmin3. Then, start/stop/start/etc run fine lookup for
postmaster.pid in /var/lib/pgsql/9.6/data.
