DB2基础版本安装
3.5 核心文件安装
注：需要在所有节点上都安装DB2 pureScale
3.5.1 使用 db2_install安装
3.5.1.1 AIX服务器DB2软件安装
用root用户登录到AIX服务器，具体安装步骤如下： ? 解压DB2数据库产品映像文件 #cd /tmp/db2v105 #gzip -cd DB2_Svr_10.5.0.4_AIX.tar.gz | tar -xvf - 解压后，DB2数据库安装介质目录位于/tmp/db2v105/server。 ? db2prereqcheck命令检查软硬件是否符合安装需求 # cd /tmp/db2v105/server # ./db2prereqcheck -v 10.5.0.0 ? 安装DB2数据库产品 执行db2数据库安装命令（需root用户运行）： # ./db2_install 系统回显如下信息，DB2开始安装，在安装过程中，会提示你选择安装目录(输入yes)，需要安装的产品(输入server)，是否安装pureScale 特性(输入yes)

3.5.2 GPFS 文件系统配置与挂载
3.5.2.1 AIX GPFS文件系统配置与挂载
安装完DB2之后，root在主CF节点(cnwbzp0222)上执行：
#/opt/IBM/db2/V10.5/instance/db2cluster_prepare -instance_shared_dev /dev/hdisk1 系统回显：
-bash-4.2# /opt/IBM/db2/V10.5/instance/db2cluster_prepare -instance_shared_dev /dev/hdisk1 DBI1446I The db2cluster_prepare command is running. DB2 installation is being initialized.
