The steps below are only applicable for installation in Non-Appliance mode, and should be performed by your Linux administrator. |

This video demonstrates how to prepare a RHEL 7.8 operating system for DPOD Non-Appliance mode installation. Use it just as a demonstration, as it is not kept up-to-date with every change in the requirements. When preparing the operating system, you should follow the procedure provided below. |
Subject | Action | ||||||
---|---|---|---|---|---|---|---|
Supported operating system | Verify that the operation system is supported by DPOD as described in System Requirements. After the server OS is installed, this can be verified using the following command:
| ||||||
Resources allocation | Ensure Allocate resources according to the chosen architecture type as listed in System Requirements . After the server OS is installed, this can be verified using the following commands:
| ||||||
Network card | Ensure you have at least one network card installed and configured with full access to network services, such as DNS and NTP (the same as your Gateways) - see Network Preparation. Some configurations, such as the Cell environment, require 2 network cards. See Network Preparation for more details. | ||||||
Root access | Installation must be The installation must be performed by a root user. You can NOT run it with sudo You cannot use sudo instead. However, you may run it after running the command: | ||||||
Disks, mount points / file systems and logical volumes
| For both Production and Non Production installations, the Standard Edition requires DPOD requires at least 3 disks (LUNs / physical / virtual) You will need to for the operating system, for the application and for the data. Some configurations, such as the Cell environment, require additional disks. Please allocate the mount points / file systems on the different disks, as described in Table 1 below. It is strongly recommended to use logical volume manager (LVM) - particularly for the data disks. ToOnce configured, you may verify there are at least 3 disks using the following command:
Tip: to create the mount points / file systems during RHEL installation:
| ||||||
Store service dedicated OS user and group | The Store service requires a dedicated OS user and group to run. Consider executing the following command:
| ||||||
OS locale | The supported OS locale is en_US.UTF-8. Use the following procedure to check Check the OS Locale Configuration and change it if necessary. | ||||||
Installation file and environment | Ensure your /tmp directory has at least 1GB of free space Installation from a different directory is possible. If you opt to run the install from a directory other than /tmp, ensure that this directory:
Download the CEF file and transfer it to the installation directory (e.g. /tmp) on the pre-installed OS server. Execute the following command from the pre-installed OS server terminal: | ||||||
Setup your network (consult your network admin)SELinux configuration | Changes in SELinux configuration might be needed. If SELinux is enforced on the DPOD server, please review possible required configuration changes. | ||||||
Setup DNS | Setup DNS - your network admin may need to assist you with this action. Make sure you can ping to your LDAP, Mail/SMTP Server, NTP Server. | ||||||
Using yum on RedHat | For RedHat only: Your system might need to be registered and subscribed to the Red Hat Customer Portal to be able to install all prerequisites using
| ||||||
Setup NTP | Setup NTP - it has to be the same used for one configured in your IBM DataPower Gateways.
| ||||||
Setup hosts file | Verify that the /etc/hosts file includes an entry with your server name mapped to your external server IP. To find your server name, you may execute the command:
| ||||||
Required RPMs | Verify the existence of the following RPMs from the official RedHat/CentOS yum repositories:
The installation is usually performed by executing yum:
If this command can not fails to find the package on account of it not being included in the repository, you will need to add the containing repository or packages, you should manually download the RPMs RPM files and install them. | ||||||
Ensure the httpd service is enabled and started by executing the command:
| Install mod_proxy_html:
| Optional: Install Kibana OSS (kibana-oss-6.8.1) This RPM is required only if you would like to manually query the Big Data store | |||||
Optional: Install Kibana OSS (please read Kibana access limitations):
| |||||||
Cleanup | In case you are using yum, it is recommended to clean its cache to make sure there is enough space in /var (yum cache can take a lot of the space there). To clean yum cache, execute the command:
| ||||||
Firewall access to DPOD server | To configure your firewall to allow access to DPOD server at port 443, execute the following commands:
Note | You should open port access for the DNS Server, your DataPower Gateways, your SMTP server and others as described in Firewall Requirements. Please assist your network admin and Linux admin to enable access on these ports. |

Installation Compatibility Checks
There are two types of checks: Critical and Informational.
The critical checks are mandatory in order to install the system. The informational checks are highly recommended for system optimization.
Please take time to review the results of these checks after installation, and perform all applicable optimizations. The compatibility checks report can be found in /installs/logs/appliance_checks-<date time>.log
Supported programs
The only supported programs for installation on the DPOD server are infrastructure / system tools like Antivirus agents, Monitor Agents, Backup Agents etc.
Note that these system tools may affect DPOD's functionality and performance.
...
Third-Party Software
Third-party software such as antivirus, cybersecurity, monitoring, APM, endpoint protection, backup, etc. might significantly decrease the performance of DPOD and impact its functionality.
In case of functionality or performance issues, try first to disable these system toolsto disable such software.
During the resolution of issues, DPOD support will ask the customer to disable any 3rd party software in order to isolate the issues and verify their source. Support cannot be provided if the 3rd party tools are not disabled.
