5. Installing DB2 on other Linux distributions

Installation Steps

1. Initialize the RPM database.

   bash# rpm --initdb

2. Modifiy several files in /bin

   bash# mv /bin/sh /bin/sh.bash bash# ln -s /usr/bin/ksh /bin/sh bash# for f in awk basename ksh passwd sort touch; do ln -s /usr/bin/$f /bin/$f; done

3. Copy the contents of the following script to create an RPM wrapper called /bin/rpm.

   #!/bin/sh # RPM wrapper, force RPM installation without checking any dependencies if [ "$1" = "-ivh" ] then shift /usr/bin/rpm -ivh --nodeps $* else /usr/bin/rpm $* fi

4. Make the RPM wrapper executable:

   bash# chmod +x /bin/rpm

5. Install DB2 using the db2setup command by following the instructions in Section 4.

6. Create the DB2 administration server and at least one DB2 instance as described in Section 6. To simplify testing, ensure that you create the sample database when you create the DB2 instance.

Testing your DB2 installation

1. Log on to your Linux server with the DB2 instance user ID. Remember, the default user ID is db2inst1.

2. Prepare your DB2 environment by running the db2profile script:

   bash$ cd ~/sqllib bash$ . ./db2profile

3. Run a query against the sample database to test your installation.

   bash$ db2 bash$ db2 => connect to sample bash$ db2 => select * from employee

   There should be a printout of records from sample database here

   bash$ db2 => quit

After you install DB2

1. Remove the RPM wrapper script by removing, renaming, or linking it directly to /usr/bin/rpm.

   bash# rm /bin/rpm

2. Change /bin/sh back into a symlink to /usr/bin/bash.

   bash# ln -sf /usr/bin/bash /bin/sh
