# 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
