Installing IBM WebSphere MQ server on Linux

You can install a IBM® WebSphere® MQ server on either a 32-bit or 64-bit Linux® system.

Before you begin

Before you start the installation procedure, ensure that you have completed the necessary steps outlined in Preparing the system.
If this installation is not the first installation on the system, you must ensure that the crtmqpkg command can write to a temporary location. By default, the crtmqpkg command will write to the /var/tmp directory. To use a different location, you can set the TMPDIR environment variable before you run the crtmqpkg command.
To run the crtmqpkg command used in this task, you must have the pax command or rpmbuild installed.
Important: pax and rpmbuild are not supplied as part of the product. You must obtain these from your Linux distribution supplier.

About this task

Install the server by using the RPM Package Manager installer to select the components you want to install. The components and package names are listed in Choosing what to install.

Procedure

Log in as root, or switch to the superuser by using the su command.
Set your current directory to the location of the installation file. The location might be the mount point of the server DVD, a network location, or a local file system directory.
Run the mqlicense.sh script.
If you want to view a text-only version of the license, which can be read by a screen reader, type the following message:
```
./mqlicense.sh -text_only
```
The license number is displayed.
You must accept the license agreement before you can proceed with the installation.
If this installation is not the first installation of IBM WebSphere MQ on the system, you must run the crtmqpkg command to create a unique set of packages to install on the system. To run the crtmqpkg command to run on Linux, you must install the pax command and rpmbuild, which is located in the rpm-build package.
Note: The crtmqpkg command is required only if this is not the first installation of IBM WebSphere MQ on the system. If you have earlier versions of IBM WebSphere MQ installed on your system then installing IBM WebSphere MQ version 7.5 will work correctly if you install it in a different location.

To run the crtmqpkg command on a Linux system:
1. Enter the following command:
```
./crtmqpkg suffix
```
  where suffix is a name of your choosing that uniquely identifies 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.
  Note: This command creates a full copy of the installation packages in a temporary directory. By default, the temporary directory is located at /var/tmp. You must ensure that the system has enough free space before you run this command. To use a different location, you can set the TMPDIR environment variable before you run the crtmqpkg command. For example:
```
$ TMPDIR=/test ./crtmqpkg
```
2. Set your current directory to the location specified when the crtmqpkg command operation completes successfully.
  This directory is a subdirectory of the /var/tmp/mq_rpms directory, in which the unique set of packages is created. The packages have the suffix value contained within the file name. In the following example, the suffix of "1"./crtmqpkg 1 means that there is :a subdirectory named /var/tmp/mq_rpms/1/i386.
  The packages are renamed according to the subdirectory, for example:
```
From: MQSeriesRuntime-7.5.0-0.i386.rpm
To: MQSeriesRuntime_1-7.5.0-0.i386.rpm
```
Install IBM WebSphere MQ.
At a minimum, you must install the MQSeriesRuntime and the MQSeriesServer components.
- To install to the default location, /opt/mqm, use the rpm -ivh command to install each component that you require.
  For example, to install the runtime and server components to the default location, use the following command:
```
rpm -ivh MQSeriesRuntime-*.rpm MQSeriesServer-*.rpm
```
  To install all components to the default location use the following command:
```
rpm -ivh MQSeries*.rpm
```
- To install to a non-default location, use the rpm --prefix option. For each installation, all of the IBM WebSphere MQ components that you require must be installed in the same location.
  The installation path specified must be either 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, enter the following installation path to install the runtime and server components to the /opt/customLocation directory on a 32-bit Linux system:
```
rpm --prefix /opt/customLocation -ivh MQSeriesRuntime_*.rpm
MQSeriesServer_*.rpm
```

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
```
where MQ_INSTALLATION_PATH represents the directory where IBM WebSphere MQ is installed.

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 WebSphere MQ. For more information, see setmqenv and crtmqenv.
If you want to confirm that the installation was successful, you can verify your installation. See Verifying an IBM WebSphere MQ server installation, for more information.
