目前最新的CentOS 6.3中，仍然使用的是PostgreSQL 8.4版本。为了满足另一应用系统的需求，必须安装PostgreSQL 9及以上版本。本文将叙述如何使用PostgreSQL官方软件仓库和YUM工具，实现自动安装PostgeSQL 9。我使用的CentOS版本为6.3，该操作方法同样适用于使用CentOS 5, RedHat或者Fedora版本的朋友，只是需要注意下载文件时有对应的版本选择。

　　1、下载并安装PostgreSQL官方软件仓库

　　访问http://yum.pgrpms.org/repopackages.php，选择对应的操作系统版本，下载repo rpm文件。对应我的操作系统CentOS 6.3 32位版本，使用wget命令下载，操作如下：

[root@wardking ~]# wget http://yum.pgrpms.org/9.2/redhat/rhel-6-i386/pgdg-centos92-9.2-6.noarch.rpm

　　安装软件仓库

[root@wardking ~]# rpm -ivh pgdg-centos92-9.2-6.noarch.rpm

warning: pgdg-centos92-9.2-6.noarch.rpm: Header V4 DSA/SHA1 Signature, key ID 442df0f8: NOKEY

Preparing…                ########################################### [100%]

   1:pgdg-centos92          ########################################### [100%]

　　编辑CentOS-Base.repo，将目前的CentOS仓库中的版本排除

[root@wardking ~]# vi /etc/yum.repos.d/CentOS-Base.repo
# remarked out baseurl= line instead.

 

[base]

name=CentOS-$releasever – Base

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

exclude=postgresql*

 

#released updates

[updates]

name=CentOS-$releasever – Updates

mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates

#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

exclude=postgresql*

　　试一下，应该可以看到最新的PostgreSQL出现在可用软件列表中：

[root@wardking ~]# yum list postgres*
