Install an IBM MQ client on Linux

Install an IBM MQ client on a 64 bit Linux system.

Before you begin

• Before you start the installation procedure, make sure that we have completed the necessary steps outlined in Preparing the system on Linux.
• If this installation is not the only installation on the system, you must ensure that we have write access to /var/tmp.

About this task

Procedure

1. Log in as root, or switch to the superuser using the su command.
2. Make your current directory the location of the installation file. The location might be the mount point of the DVD, a network location, or a local file system directory.
3. Run the mqlicense.sh script. If you want to view a text-only version of license, which can be read by a screen-reader, type:

   ./mqlicense.sh -text_only
   

   The license is displayed. If want to accept the license without it being displayed, we can run the mqlicense.sh script with the -accept option.

   ./mqlicense.sh -accept
   

   You must accept the license agreement before we can proceed with the installation.

4. If we have multiple installations on this system, you must run crtmqpkg to create a unique set of packages to install on the system:
   1. Enter the following command:

      ./crtmqpkg suffix
      

      where suffix is a name of your choosing, that will uniquely identify the installation packages on the system. suffix is not the same as an installation name, although the names can be identical. suffix is limited to 16 characters in the ranges A-Z, a-z, and 0-9.
   2. Set your current directory to the location specified when the crtmqpkg command completes. This directory is a sub-directory of /var/tmp/mq_rpms, in which the unique set of packages is created. The packages have the suffix value contained within the filename.
5. Install IBM MQ. The minimum components you must install are the MQSeriesRuntime and the MQSeriesClient.
   • To install to the default location, /opt/mqm, use the rpm -ivh command to install each component that you require. For example, to install all components to the default location use the following command:

     rpm -ivh MQSeries*.rpm
     

     If you are using Ubuntu, add the --force-debian attribute. For example, to install all components to the default location use the following command:

     rpm --force-debian -ivh MQSeries*.rpm
     

     You must include this option to prevent seeing warning messages from the version of RPM for your platform, which indicates that the RPM packages are not intended to be directly installed using RPM.
   • To install to a non-default location use the rpm --prefix option. For each installation, all of the IBM MQ components that you require must be installed in the same location.

     The installation path specified must either be an empty directory, the root of an unused file system, or a path that does not exist. The length of the path is limited to 256 bytes and must not contain spaces.

     For example, to install the runtime and server components to /opt/customLocation on a 64-bit Linux system:

     rpm --prefix /opt/customLocation -ivh MQSeriesRuntime-V.R.M-F.x86_64.rpm
     MQSeriesClient-V.R.M-F.x86_64.rpm
     

     where:

     V

     Represents the version of the product that you are installing

     R

     Represents the release of the product that you are installing

     M

     Represents the modification of the product that you are installing

     F

     Represents the fix pack level of the product that you are installing

What to do next

• If we have chosen this installation to be the primary installation on the system, you must now set it as the primary installation. Enter the following command at the command prompt:

   MQ_INSTALLATION_PATH/bin/setmqinst -i -p MQ_INSTALLATION_PATH
  

  We can have only one primary installation on a system. If there is already a primary installation on the system, you must unset it before we can set another installation as the primary installation. For more information, see Change the primary installation.
• You might want to set up the environment to work with this installation. We can use the setmqenv or crtmqenv command to set various environment variables for a particular installation of IBM MQ. For more information, see setmqenv and crtmqenv.
