Install Required Dependencies

Db2 requires several essential packages. Install them with:

sudo apt install libaio1 ksh libpam0g libstdc++6 libxml2 libxft2 -y

These libraries are necessary for Db2 to run properly on modern Ubuntu versions.

Create a Db2 Installation Directory

Create a folder to store the Db2 installer and navigate into it:

mkdir ~/db2setup
cd ~/db2setup

Download the IBM Db2 Installer

You can download Db2 directly from IBM’s official website:

👉 https://www.ibm.com/products/db2

Alternatively, use the command line if you have a direct download link from IBM (requires IBM account login).

After downloading, extract the installation package:

tar -xvzf v11.5_linuxx64_server.tar.gz
cd server_t

Run the Db2 Installer

To begin the installation, execute the setup script:

sudo ./db2setup

This will open an interactive graphical or text-based installer depending on your system. Follow the prompts to complete the setup.

If you prefer a silent (non-interactive) installation, use:

sudo ./db2setup -r response_file.rsp

(The response file allows you to predefine installation options.)

Create a Db2 Instance

Once installation completes, create a new Db2 instance to manage databases:

sudo /opt/ibm/db2/V11.5/instance/db2icrt -u db2inst1 db2inst1

Then start the instance:

sudo su - db2inst1
db2start

You can verify if Db2 is active by checking its service status:

db2 get instance

Test Your Installation

Log into the Db2 command line processor (CLP):

db2

Then create a test database to confirm everything is working:

CREATE DATABASE testdb;
CONNECT TO testdb;

If you see “Database Connection Information” displayed, your setup was successful.

Enable Db2 on Boot

To ensure Db2 starts automatically when your server reboots:

sudo systemctl enable db2fmcd
sudo systemctl start db2fmcd

Secure Your Installation

Change default passwords for the instance user, restrict access to the Db2 directory, and consider enabling SSL communication for production environments.

Installing IBM Db2 on Ubuntu 25.10 gives you a stable, flexible, and enterprise-grade database environment that integrates smoothly with other Linux tools and applications. Whether you’re developing applications or managing business-critical data, Db2 offers reliability and performance you can count on.
