db2 9.7 for linux 5.4安装详细步骤

http://www.2cto.com/database/201205/130463.html

1、解压缩安装包

#gunzip v9.7_linuxia32_server.tar.gz

#tar -xvf v9.7_linuxia32_server.tar

2、进入解压后的文件目录，执行安装：（我们选择手动安装）

注意：DB2_install为手动安装 db2_setup为图形安装

www.2cto.com

#./Db2_install-------no-----aese

3、创建DB2运行所需的组和用户：

#groupadd -g 901 db2grp

#groupadd -g 902 db2fgrp

#groupadd -g 903 db2agrp

#useradd -g db2grp -u 801 -d /home/db2inst1-m -s /bin/bash db2inst1 --管理当前实例

#useradd -g db2fgrp -u 802 -d /home/db2fenc-m -s /bin/bash db2fenc

#useradd -g db2agrp -u 803 -d /home/db2das-m -s /bin/bash db2das --管理所有实例

4、设置密码：

passwd db2inst1

passwd db2fenc

passwd db2das

5、创建实例

#cd /opt/ibm/db2/V9.7/instance

#./dascrt -u db2das

#./db2icrt -u db2inst1 db2inst1

注意：DBI1922N The host name is not valid.报无法解析错误，在/etc/hosts文件中添加解析参数即可 www.2cto.com

注释：

Dascrt：创建的是DB2 adminstration server，每台服务器只有一个这种server，为进行DB2管理（比如运行控制中心）所必须，同时指定其管理用户是db2das。

db2icrt：创建的是实例，其名字一般和管理用户名一样，这里均为db2inst1。

6、启动DB2

# su - db2das

$ db2admin start ----启动DB2管理服务器

SQL4409W The DB2 Administration Server is already active.

$su - db2inst1

$ db2start ----启动数据库实例

05/07/2012 01:30:04 0 0 SQL1063N DB2START processing was successful.

SQL1063N DB2START processing was successful.

7、检查DB2是否起来，状态如下：

[db2inst1@jetsen ~]$ ps -ef|grep db2

db2das 10828 1 0 01:23 ? 00:00:00 /home/db2das/das/adm/db2dasrrm

root 11345 1 0 01:23 ? 00:00:00 /opt/ibm/db2/V9.7/bin/db2fmcd

db2das 11354 1 0 01:23 ? 00:00:00/opt/ibm/db2/V9.7/das/bin/db2fmd -i db2das -m/opt/ibm/db2/V9.7/das/lib/libdb2dasgcf.so.1

root 17267 2768 0 01:29 pts/1 00:00:00 su - db2das

db2das 17268 17267 0 01:29 pts/1 00:00:00 -bash

root 17329 17268 0 01:29 pts/1 00:00:00 su - db2inst1

db2inst1 17332 17329 0 01:29 pts/1 00:00:00 -bash

root 17446 1 1 01:29 pts/1 00:00:01 db2wdog 0

db2inst1 17448 17446 1 01:29 pts/1 00:00:01 db2sysc 0

root 17449 17448 0 01:29 pts/1 00:00:00 db2ckpwd 0

root 17450 17448 0 01:29 pts/1 00:00:00 db2ckpwd 0 www.2cto.com

root 17451 17448 0 01:29 pts/1 00:00:00 db2ckpwd 0

db2inst1 17455 17448 1 01:30 pts/1 00:00:01 db2vend (PD Vendor Process -1)

db2inst1 17462 17446 0 01:30 pts/1 00:00:01 db2acd 0,0,0,0,1,0,0,0000,1,0,8a67a4,14,1e014,2,0,1,11fd0,0x125f0000,0x125f0000,1600000,588003,2,b5800b

db2inst1 17494 17332 0 01:32 pts/1 00:00:00 ps -ef

db2inst1 17495 17332 0 01:32 pts/1 00:00:00 grep db2

[db2inst1@jetsen ~]$

8、配置DB2自动启动，用root用户登录

#cd /opt/ibm/db2/V9.7/instance/

# ./db2iauto -on db2inst1

9、配置网络

#su - db2inst1

$db2 update dbm cfg using SVCENAME50000 ----改变DB2的远程访问端口，默认是5000

$db2set DB2COMM=TCPIP ----修改DB2的连接方式为TCPIP，

注意：也可以通过JDBC,ODBC等方式来访问DB2数据库

10、实例的启动和关闭

#su - db2inst1

$db2 force applications all ----关闭所有和DB2相关的应用程序

$db2stop ----关闭数据库实例

$db2start ----启动数据库实例

11、创建数据库

#su - db2inst1

$db2 create database test ----创建数据库实例

DB20000I The CREATE DATABASE command completed successfully.

12、连接到我们刚才创建的数据库

#su - db2inst1

$db2 www.2cto.com

db2 => Connect to test user db2inst1

Enter current password for db2inst1:

Database Connection Information

Database server = DB2/LINUX 9.7.5

SQLauthorization ID = DB2INST1

Local database alias = TEST

db2 =>

附录：

1、创建演示数据库

#su - db2inst1

$ $cd /opt/ibm/db2/V9.7/bin

$ ./db2sampl

Creating database "SAMPLE"...

Connecting to database "SAMPLE"...

Creating tables and data in schema "DB2INST1"...

Creating tables with XML columns and XML data in schema"DB2INST1"...

'db2sampl' processing complete.

2、访问刚创建的数据库

$ db2

www.2cto.com

db2 => connect to sample

Database Connection Information

Database server = DB2/LINUX 9.7.5

SQLauthorization ID = DB2INST1

Local database alias = SAMPLE

db2 =>

3、常用操作命令

db2 =>connect to sample ---连接到sample数据库

db2 =>list tables ---查看库下面的所有表

db2 => select * from staff wheredept=10 ---查询某张表dept等于10的所有记录

db2 => quit www.2cto.com ---退出db2

DB20000I The QUIT command completed successfully.

$ db2ilist; ---查看实例列表

db2inst1

$ db2 get instance ---查看当前所运行的实例

Thecurrent database manager instance is: db2inst1
