Installing an IBM MQ client on Linux using rpm

Installing an IBM® MQ client on a 64 bit Linux® system.

Before you begin

  • Before you start the installation procedure, make sure that you 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 you have write access to /var/tmp.

About this task

This task describes the installation of the client, using the RPM Package Manager installer to select which components you want to install. You must install at least the Runtime and Client components. The components are listed in IBM MQ rpm components for Linux systems.

Procedure

  1. Log in as root, or with sufficient authority to run the following commands.

    You can do this by adding sudo before the commands, or by changing to the root user in the shell with the su command. For more information, see Exploring the differences between sudo and su commands in Linux.

  2. Set your current directory to the location of the installation packages.

    The location might be the mount point of a DVD, a network location, or a local file system directory. See Where to find downloadable installation images.

  3. [MQ 9.2.0 Jul 2020] From IBM MQ 9.2.0, you have the option of accepting the license before or after installing the product. To accept the license before installing, run the mqlicense.sh script:
    ./mqlicense.sh

    The license agreement is displayed in a language appropriate to your environment and you are prompted to accept or decline the terms of the license.

    If possible, mqlicense.sh opens an X-window to display the license.

    If you need the license to be presented as text in the current shell, which can be read by a screen reader, type the following command:
    ./mqlicense.sh -text_only 
    See License acceptance on IBM MQ for Linux for more information about license acceptance.
  4. If you 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. Optional: [MQ 9.2.4 Nov 2021]Obtain the IBM MQ public signing gpg key and install it into rpm.
    rpm --import ibm_mq_public.pgp
    The IBM-provided RPMs are signed with a digital signature, and your system will not recognize that signature without further steps. This only needs to be done once for each system. For more information, see IBM MQ code signatures.
    The validity of any of the IBM MQ RPMs can then be verified, for example:
    # rpm -Kv MQSeriesRuntime-9.2.4-0.x86_64.rpm
    MQSeriesRuntime-9.2.4-0.x86_64.rpm:
        Header V3 RSA/SHA256 Signature, key ID 0209b828: OK
        Header SHA1 digest: OK
        V3 RSA/SHA256 Signature, key ID 0209b828: OK
        MD5 digest: OK
    
    Note: If you skip this step, then a harmless warning might be issued during RPM installation to indicate there is a signature but the system does not recognize the signing key, for example:
    warning: MQSeriesRuntime-9.2.4-0.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 0209b828: NOKEY
  6. Install IBM MQ.
    The minimum components you must install are the MQSeriesRuntime, the MQSeriesClient, and the MQSeriesGSKit.
    • 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 you 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
    
    You can have only one primary installation on a system. If there is already a primary installation on the system, you must unset it before you can set another installation as the primary installation. For more information, see Changing the primary installation.
  • You might want to set up the environment to work with this installation. You 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.
