DB2数据库安装

建用户

# groupadd db2iadm1

# useradd -m -g db2iadm1 -d /home/db2inst1 db2inst1

# groupadd db2fadm1

# useradd -m -g db2fadm1 -d /home/db2fenc1 db2fenc1

# groupadd dasadm1

# useradd -m -g dasadm1 -d /home/dasusr1 dasusr1

一、下载安装DB2

到IBM网站下载免费的DB2 Express-C 9.5，网址/developerworks/cn/downloads/im/udbexp/

下载db2exc_952_LNX_x86.tar.gz到/home/hz

使用 tar -xvf db2exc_952_LNX_x86.tar.gz命令解压，

解压到/home/hz/expc/目录下，

X/home/hz/expc/db2setup，命令行终端使用/home/hz/expc/db2_install来进行DB2的安装。

安装时若提示找不到libaio.so.1及libstdc++.so.5，则先下载安装相应的软件包。

libaio.so.1 -> libaio1

# aptitude install libaio1

libstdc++.so.5 -> libstdc++5

# aptitude install libstdc++5

二、配置DB2

#创建用户组及用户

#与实例名同名？

groupadd -g 2000 db2iadm1

useradd -m -g db2iadm1 -d /home/db2inst1 db2inst1

passwd db2inst1

>db2inst1

#the user under which fenced UDFs and fenced stored procedures will be run.

#可以与上面同一个用户

groupadd -g 2100 db2fadm1

useradd -m -g db2fadm1 -d /home/db2fenc1 db2fenc1

#创建实例
