Supported operating system

Verify that your operation system is one of the supported operating systems described in System Requirements.

ArchitectureResources allocation

Ensure to select the correct architecture type and that all resources listed in System Requirements are made available.

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.

Prepare Admin Root access

Installation must be performed by a root user.

You can NOT run it with sudo. You can run However, you may run it after running the command: su -

Prepare diskDisks, mount points / file systems and logical volumevolumes


Info

Tuning requirement - define 3 Disks with LVM and with size and mount points as defined below

For both Production and Non Production installations, the Standard Edition requires 3 disks (LUNs / physical / virtual) to support throughput.

You will need to allocate the following 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 data disks.This can be done during RHEL installation by choosing

The minimum file system sizes for the different installation types are described in table 2 below.


To create the mount points / file systems during RHEL installation:

  • Choose Installation Destination option.
You will then need to select
  • Select all Local Standard drives and choose option "I will configure partitioning" under the "Other Storage Options" section.
You should follow
  • Follow table 2 and add all mount points with required definitions using the "+" button.
to
  • To create a volume group (sys, app, data) open the "Volume Group" list box and choose "create new volume group ..."
  • This way you can partition your 3 (logical) drive exactly as stated in table 2.
The minimum file system sizes for the different installation types are described in table 2 below


After configuring the required mount points / file systems you can use the command "df -h" to make sure all free space requirements are met.

Your mount point configuration should resemble the following :

Prepare Store service dedicated OS user and group

The Store service requires a dedicated OS user and group to run.

User can use Consider executing the following command: groupadd storeadms && useradd -g storeadms -md /home/storeadm -s /bin/bash storeadm

Configure OS locale

The supported OS locale is en_US.UTF-8.

Use the following procedure to check the supported locale configuration OS Locale Configuration and change it if necessary.

Prepare your installation 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:

    • Has at least 1GB of free space
    • Is NOT one of these folders: /app, /logs, /data, /shared, /installs

Download the CEF file and transfer it to the installation directory (e.g. /tmp directory ) on the pre-installed OS server.

Execute the following command from the pre-installed OS server terminal: chmod 755 ./<File Name>

Setup your network (consult your network admin)

Setup DNS - your network admin may need to assist you with this action.


Setup NTP - it has to be the same used for your IBM DataPower Gateways.

  • Consult your Linux and network admin about the proper way to configure this service.
  • Ensure the NTP RPM is installed. Consider executing the following commandcommands:
    • yum install ntp
    • ntpdate <ntp server hostname>
    • systemctl enable ntpd.service
    • systemctl start ntpd.service 

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: hostname

Verify all required Required RPMs are installed

Verify the existence of the following RPMs from the official RedHat/CentOS yum repositories:
  • httpd version 2.4.6-67 and above (together with the following dependencies: mailcap, apr, httpd_tools)
  • mod_ssl
  • curl
  • wget
  • unzip
  • iptables
  • iptables-services
  • bc
  • fontconfig

The installation is usually performed by executing: yum install httpd mod_ssl curl wget unzip iptables iptables-services bc fontconfig

If this command can not find the package on account of it not being included in the repository, you will need to add the containing repository or manually download the RPMs files and install them.
For RedHat Onlyonly - Execute  consider executing the following command: subscription-manager repos --enable=rhel-7-server-rh-common-rpms


Ensure the httpd service is enabled and started by executing the command: systemctl enable httpd.service Ensure the httpd service is started by executing the command: && systemctl start httpd.service


Install mod_proxy_html:
  • This RPM is not always accessible from existing repositories. Try first to install it by executing the command: yum install mod_proxy_html
    If you get the error "No package mod_proxy_html available. Error: Nothing to do", you will need to download the RPM yourself, using one of the following methods:
    • Method 1 - download the RPM
      • Find your httpd version by executing the command: rpm -qa | grep httpd
      • The system will print something resembling httpd-2.4.6-67.el7_2.4.x86_64. This is the mod_proxy version you need to download.
      • For RedHat
      Only url
      to
      • URL to match the httpd version you found above). Use wget or any other mechanism to download, and ensure to place the RPM inside the /tmp directory of the pre-installed OS server.
      • Install the RPM by executing the command:  rpm -Uvh mod_proxy_html-2.4.6-67.el7_2.4.x86_64.rpm (Note: your version may vary, as described above)
    • Method 2 - add a repository and install it from the repository using the commands (
    RedHat Only
    • For RedHat only)

      • subscription-manager repos --enable=rhel-7-server-optional-rpms

      • yum install mod_proxy_html


OPTIONAL - : Install kibana Kibana OSS (kibana-oss-6.6.1)

This RPM is required only if you would like to manually query the Big Data store.:

Configure kibana Kibana (edit kibana.yml): 

  • server.port: 5601
  • server.host: "montier-es-http"
  • server.basePath: "/op/kibana"
  • elasticsearch.hosts: "http://montier-es-http:9200"
  • elasticsearch.shardTimeout: 300000
Open your firewall to Firewall access to DPOD server

To configure your firewall for open to allow access to the DPOD server for at port 443, execute the following commands:

Note

These commands may not be applicable if your system has no builtin firewall.

firewall-cmd --zone=public --add-port=443/tcp --permanent

firewall-cmd --reload

iptables-save | grep 443


If, for any reason, you need to remove this access (close the port) - execute the following commands:

firewall-cmd --zone=public --remove-port=443/tcp --permanent

firewall-cmd --reload

iptables-save | grep 443


Note

You should open port access for the DNS Server, your DataPower devicesGateways, your SMTP server and others as described in firewall rules Firewall Requirements.

Please assist your network admin and Linux admin to enable access on these ports.
