We usually don't offer support on RHEL installations as most of our customers that are using RHEL have they own ways of installing and configuring RHEL. 

StruxureWare Data Center Operation 8.0.1 or later versions can be installed on a Red Hat Enterprise Linux 7 server.

Installation requirements

Prerequisite: Before starting the installation procedure, make sure that the general System Requirements are fulfilled in addition to these:

  • A server running RHEL 7.x with at least minimum install selected.
  • Access to RHEL packages either by using an active RHEL subscription or inserting a Red Hat Enterprise Linux Server x86_64 DVD

  • Disk space:
    • /data is used for indexes and ETL configuration. Minimum size 5 GB.
    • /data/backup is used for backups. Minimum size 50 GB. Backups should always be mounted on a remote network share.
    • /opt/jboss-as is used for the application server. Minimum size 10 GB.
    • /var/lib/pgsql is used for the postgres database. Minimum size 30 GB.
    • /var/log is used for log files. Minimum size 5 GB.
  • Total amount of space recommended for an installation is at least 100 GB in addition to the operating system.
  • Optional: Due to a bug in the Red Hat linux kernel, it is recommended to upgrade to 3.10.0-327.22.2.el7 or later. Some audit log messages may not be logged if you have a kernel version earlier than 3.10.0-327.22.2.el7.


If special configuration has been done, ensure the sudoers file /etc/sudoers includes the following lines before installing or upgrading:

If, for security reasons, you do not want to enable one or both of the above lines, contact Technical Support for a list of changes needed for the installation to proceed. For optimum support, supply your sudoers configuration in your support request.

Installing the StruxureWare Data Center Operation server on Red Hat Enterprise Linux

  1. Download the installation file (StruxureWareDataCenterOperation-<version no>.iso ) from a location provided by the support team. To locate the telephone number for your region, visit Contact Us.

    Note:  The below commands should be run with root credentials.
  2. Upload the installation file to: /tmp/
  3. Create ISO mount point /tmp/iso
  4. Mount the installer by running the command: mount -o loop /tmp/StruxureWareDataCenterOperation-<version no>.iso /tmp/iso
    (where you replace <version no> with the 8.x.x version number)
  5. Execute the install script:  bash /tmp/iso/dco-install/install.sh
    However, if installing a cluster node, execute the install script: bash /tmp/iso/dco-install/install.sh --clusternode
  6. Un-mount ISO: umount /tmp/iso/

Non-mandatory creation of users and groups

  Click here for details...

During the installation process the setup script will automatically create these user accounts: dcojboss, dcoplat, postgres, and apache.

If required, these accounts may be manually added by executing these commands with root credentials prior to installation:

Add dcojboss user and group

Add dcoplat user and group

Add postgres user

The postgres package performs the above commands. Changing UID/GID is currently untested.

Add apache user

The httpd package performs the above commands. Changing UID/GID is currently untested.
