Install PostgreSQL on Solaris 11 (11.3)

Here are some quick instruction on how to install PostgreSQL on Solaris 11.3.
  • PostgreSQL 9.5: http://www.postgresql.org/

Add a user

At this time  postgres user exists on Solaris, so I am going to use that, but just in case then:

# groupadd -g 90 postgres
# useradd -u 90 -S files -s /usr/bin/pfksh -d / -g postgres postgres
# grep postgres /etc/passwd  /etc/group
/etc/passwd:postgres:x:90:90:PostgreSQL Reserved UID:/:/usr/bin/pfksh
/etc/group:postgres::90:

Setup

# mkdir /usr/local/postgres
# chown postgres:postgres /usr/local/postgres
# su - postgres
# cd /usr/local

# bunzip2 < /tmp/postgresql-9.5.3-S11.i386-64.tar.bz2 | tar xpf -
# /usr/local/postgres/9.5-pgdg/bin/64/initdb -D /usr/local/postgres/data
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale "C".
The default database encoding has accordingly been set to "SQL_ASCII".
The default text search configuration will be set to "english".

Data page checksums are disabled.

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

/usr/local/postgres/9.5-pgdg/bin/64/pg_ctl -D /usr/local/postgres/data -l logfile start

Thank you Andrew for your kind sharing.

when creating the SMF for Postgre process, is it root shell or postgres user shell?

Andrew Watkins said...

The "Create SMF" part is done at the root shell.
As you can tell the postgres service is run as user postgres with the updates above (yellow highlight).
Cheers.

if you need UTF8 charset
./initdb -d /usr/local/postgres/data -E UTF8
