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 for more details.

Root access

Installation must be performed by a root user.

You cannot use sudo instead. However, you may run it after running the command: su -

Disks, mount points / file systems and logical volumes

Tip: to create the mount points / file systems during RHEL installation:

The Store service requires a dedicated OS user and group to run. Consider executing the following command:

groupadd storeadms && useradd -g storeadms -md /home/storeadm -s /bin/bash storeadm

The supported OS locale is en_US.UTF-8. 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:

• • 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) on the pre-installed OS server.

Execute the following command from the pre-installed OS server terminal:

chmod 755 ./<File Name>

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.

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 yum.
Registration and subscription may differ between organizations, so use the following commands just for as a demonstration:

subscription-manager register
subscription-manager attach --auto
subscription-manager repos --enable=rhel-7-server-rh-common-rpms

Setup NTP - it has to be the same one configured in 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 commands:
  

  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

Required RPMs

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:

yum install httpd mod_ssl curl wget unzip iptables iptables-services bc fontconfig

If this command fails to find the packages, you should manually download the RPM files and install them.

Ensure the httpd service is enabled and started by executing the command:

systemctl enable httpd.service && systemctl start httpd.service

• 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 - Download the mod_proxy with the correct version from the following url:
      https://access.redhat.com/downloads/content/mod_proxy_html/2.4.6-45.el7/x86_64/f21541eb/package (change the version part of the 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 (For RedHat only)
    subscription-manager repos --enable=rhel-7-server-optional-rpms
yum install mod_proxy_html

Optional: Install Kibana OSS (please read Kibana access limitations):

• Download the RPM from: https://artifacts.elastic.co/downloads/kibana/kibana-oss-6.8.11-x86_64.rpm
• Please follow instructions on https://www.elastic.co/guide/en/kibana/6.8/rpm.html#install-rpm

• Configure Kibana (edit kibana.yml):
  

  Code Block
  server.port: 5601 server.host: "montier-es-http" server.basePath: "/op/kibana" elasticsearch.hosts: "http://montier-es-http:9200" elasticsearch.shardTimeout: 300000

  
  

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:

yum clean all
