Install PostgreSQL Pada cPanel/WHM Server

PostgreSQL merupakan salah satu basis data yang paling banyak digunakan saat ini, selain MySQL dan Oracle. PostgreSQL menyediakan fitur yang berguna untuk replikasi basis data. Fitur-fitur yang disediakan PostgreSQL antara lain DB Mirror, PGPool, Slony, PGCluster, dan lain-lain.

PostgreSQL adalah sistem database yang kuat untuk urusan relasi, open source. Memiliki lebih dari 15 tahun pengembangan aktif dan sudah terbukti segala rancangan arsitekturnya telah mendapat reputasi tentang "kuat", "handal", "integritas data", dan "akurasi data".

Install PostgreSQL pada cPanel/WHM server sangatlah mudah, ketikkan command berikut:

/scripts/installpostgres

[bash]
root@server5 [~]# /scripts/installpostgres
This script will install PostgreSQL 7.4.x or later
If you have an older version installed you wil need to
Dump your databases to a file and then restore them
after the install as 7.4.x is not backwards compatible.
If you do not have any databases, you can just run:
mv /var/lib/pgsql /var/lib/pgsql.old
/sbin/service postgresql stop
/sbin/service postgresql start
to force creating a 7.4.x style setup. Do not do this if
you have databases that you wish to keep!
