Configure YUM repository

vim /etc/yum.repos.d/CentOS-Base.repo

[base] and [updates] sections添加：

exclude=postgresql*

Install PGDG RPM file

go http://yum.postgresql.org and find your correct RPM.

For example, to install PostgreSQL 9.3 on CentOS 6 64-bit:

打开 http://yum.postgresql.org/repopackages.php#pg93 后找到CentOS 6 - x86_64

then：

yum localinstall http://yum.postgresql.org/9.3/redhat/rhel-6-x86_64/pgdg-centos93-9.3-1.noarch.rpm

Install PostgreSQL

list available packages:

yum list postgres*

For example, to install a basic PostgreSQL 9.3 server:

yum install postgresql93-server

Other packages can be installed according to your needs.

配置

After installing the packages, a database needs to be initialized and configured.

PostgreSQL data directory（/var/lib/pgsql/9.3/data） contains all of the data files for the database.

Initialize

The first command (only needed once) is to initialize the database：

service postgresql-9.3 initdb
正在初始化数据库：                                         [确定]

Startup

开机启动：

chkconfig postgresql-9.3 on
service postgresql-9.3 start
