=head1 pgsqlsetup
|
|
|
|
|
|
|
|
This is script is called after the installation or upgrade of PostgreSQL
|
|
on xCAT. It will automate the setup of the PostgreSQL and xCAT to run
|
|
xCAT on the PostgreSQL DB on AIX and Linux.
|
|
On AIX 6.1 or later , It will setup an xcatdb database ,a postgres id,
|
|
a xcatadm id and password to be used in the /etc/xcat/cfgloc file
|
|
to access the database.
|
|
On Linux , It will setup an xcatdb database , and get an xcatadm password
|
|
to be used in the /etc/xcat/cfgloc file to access the database.
|
|
On Linux, the xcatadm does not need to be created and postgres is already
|
|
created by the install.
|
|
It will interact for the
|
|
password to assign to the xcatadm userid for the Unix id and PgSQL database
|
|
id.
|
|
Setups up AIX 6.1+ and Linux, but most work needs to be done on AIX.
|
|
See man pgsqlsetup for more information and the xCAT2SetupPostgresql.pdf
|
|
documentation.
