(转载)db2 9.7 for linux 5.4安装详细步骤 (通过控制台安装配置)

今天在redhat5下通过  console 安装db2 v9.7，以前都是通过图形界面进行傻瓜式安装。我转载的这篇文章写得很详细，很到位，经过亲测，非常成功的安装完毕。转载于：http://www.2cto.com/database/201205/130463.html   

 

 

db2 9.7 for linux 5.4安装详细步骤

 

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

#./Db2_install-------no-----ese

 

 

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

 

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                                         
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   
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
  
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                         ---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
