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

Download the installation file: StruxureWareDataCenterOperation-Installer-x.x.x.el6.tar

Note:  These commands should be run with root credentials.

  1. Upload the installation file to /tmp/
  2. Extract the installer by running the command: tar xvf /tmp/StruxureWareDataCenterOperation-Installer-x.x.x.el6.tar -C /tmp
  3. Execute the install script:  bash /tmp/dco-install/
    However, if installing a cluster node, execute the install script: bash /tmp/dco-install/ --clusternode

Changes to the system

The following system changes are applied during installation of the StruxureWare Data Center Operation software.

  • DCO will install the listed packages if not already installed. Here is a list of dependent packages for Red Hat Enterprise Linux installation
  • iptables rules are set to DCO default locked down settings.
  • The SNMPd configuration is replaced with a DCO configuration to provide SNMP status for the DCO services.
  • The NTP configuration is changed to use default RHEL NTP servers. This can be changed afterwards through the server management interface (Webmin).
  • The PostgreSQL configuration is replaced and certificates for the database get generated during install.
  • The Keepalived configuration is replaced.
  • SELinux is disabled.
  • CTRL+ALT+DELETE reboot is disabled.
  • UseDNS in SSH is disabled.
  • TCP Keepalive settings are modified.
  • Kernel shared memory, huge pages and network memory settings are modified.
  • The sudo configuration was changed, adding sudo permissions to operations-platform and dcojboss user, removing requiretty parameter.
  • logrotate has been configured to handle DCO and PostgreSQL logs.
  • Loading kernel module ip_vs and ip_vs_rr
  • The Apache configuration is modified.
  • The Webmin configuration is modified, disabling unused modules and changing security configuration.
  • Enabling PostgreSQL start at boot.
  • The default java was switched to Oracle 1.6.
  • Maximum number of files has been increased to 100000 for JBoss (dcojboss) and root users.
  • Sudoers rules have been added for the dcojboss user to allow creation of ETL databases

Manual control of creation of users and groups (optional)

During the installation process the setup script will automatically create 3 user accounts: dcojboss, dcoplat and postgres.

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.

Installing StruxureWare Data Center Operation clients

The server installation has been completed.

  1. On the client computer, type the server's IP address in a Web browser.
  2. On the Data Center Operation server's download page, click to download StruxureWare Data Center Operation and follow the instructions in the installation wizard.

  3. On the Data Center Operation server's download page, click to download the add-on modules according to your licenses and follow the instructions in the installation wizard.

  4. Repeat the installation steps on all client computers.

Uninstalling Data Center Operation on Red Hat Enterprise Linux

When you uninstall Data Center Operation server, some files will still exist on the server. This causes no problems in regards to installing a new Data Center Operation
Running the uninstall command will create a new file, isx-operation/config.rpmsave, containing all general system configurations. 

However, if your isx-operations/config file has been modified to embrace any custom configurations (this is not typically the case), these will be lost in the uninstall process.
