This tutorial explains the installation steps of the DB2 database under Inux because of the need to learn the DB2 database recently.

Before installing, please review the DB2 version and license instructions to learn more, first understand what version to install, here I use the latest express-c version, this version is provided for the individual learning version.

The management client is no longer with the control center after the v9.7 version, but instead uses the Data Studio client.

Linux version:

The Linux version of the DB2 database uses the official free version of the operating system with the CentOS6.2.

Installation process:

1. Download: db2_v101_linuxia32_expc.tar.gz

2, decompression, after the completion of the decompression will be in the current directory has a./expc folder

tar -zxvf db2_v101_linuxia32_expc. tar. gz

Post Address:

3. Enter this directory

[Email protected] opt]# CD expc/

4. Perform the installation

[Email protected] expc]#./db2_install

5. Add groups and Users:

Group (user name)
DB2IADM1 (Db2inst1)

2001-m-g db2iadm1-d/home/-m-g db2fadm1-d/home/passwd   passwd db2fenc1

6, install license (product license) PS: If it is EXPRESSC version do not have to do

pwd/opt/ibm/db2/v10. 1/chmod775 *[[email protected] adm]$. /db2licm-a/tmp/seagull/db2v10/license/db2ese_c.lic

8. Create a DAS Management Server

In order for the remote client to be able to control the database server with the control center, it is necessary to install DAS on the database server, of course, if it is only remote connection rather than remote management, you can not install, here I installed a bit.

[Email protected] expc]# groupadd-g2002Db2asgrp[[email protected] expc]# useradd-m-g db2asgrp-d/home/db2as db2as[[email protected] expc]#passwdDb2as[[email protected]~]$su-db2as # test new user here [[email protected]~]$su# Enter root access [email protected]~]# cd/opt/ibm/db2/v10.1/instance/[email protected] instance]#./DASCRT-u db2asdbi1070i program DASCRT completed successfully. [Email protected] instance]#su-Db2as[[email protected]~]$ db2admin startsql4409w The DB2 administration Server is already active.

9. Set the port number


In the last add Line # Ps:vim shortcut key, enter "G" in command mode the last line of the jump knife.

Db2inst1 50000/tcp

10, DB2 configuration, to switch to the user Db2inst1
Db2set Db2_extended_optimization=on
Db2set Db2_disable_flush_log=on
Db2set Autostart=yes
Db2set Db2_striped_containers=on
Db2set db2_hash_join=y
Db2set Db2comm=tcpip
Db2set db2_parallel_io=*
Db2set db2codepage=819 # PS: This place is more important.
# DB2 Update Database Manager configuration using Svcename Db2inst1

11. Set Svcename to the port number or service name in/etc/services?

[[Email protected] ~]$ DB2 get dbm Cfg| grep svcenametcp/IP Service name (SVCENAME) =

Post Address:

Locate Svcename If the current value is not the server-side port number or service name, make the update settings.

[[Email protected] ~~]$ DB2 get dbm Cfg| grep svcenametcp 50000

# PS:svcename needs to be used when connecting to the client

12. You need to shut down the firewall before starting DB2, otherwise you will not be able to connect at all (this place has been a long time), under the root User: service iptables stop

13. Open DB2, execute: Db2start, if the state is turned on, then stop, execute: db2stop.

PS: Refer to the link below

Settings view:

PS: After restarting the machine encountered a problem, is to shut down the firewall unresponsive, open the shutdown database unresponsive, remote cannot connect to the database, the solution is to restart the server, and then in order to shut down the firewall, and then restarted the DB2 database.
