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)

. Some configurations, such as the Cell environment, require 2 network cards. See Network Preparation for more details.

Root access

The installation must be performed by a root user.

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

The installation will add entries to the PATH variable using .bash_profile. Make sure these entries are maintained during the login sequence (do not override with a fixed PATH).
Do not use script command during the login sequence to make typescript of the terminal session for audit, as this will cause various scripts to hang.

Disks, mount points / file systems and logical

volumes

Once 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:

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

.

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 as a demonstration:

subscription-manager register
subscription-manager attach --auto
subscription-manager repos --enable=rhel-7-server-rh-common-rpms
subscription-manager repos --enable=rhel-7-server-optional-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.
• For RHEL 7.x

  • 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

• For RHEL 8.x
  

  • Ensure the Chrony RPM is installed. Consider executing the following commands:
    

    yum install chrony
chronyd -q 'server {ntp_server_name} iburst'
systemctl enable chronyd.service
systemctl start chronyd.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
• mod_proxy_html
• curl
• wget
• unzip
• iptables
• iptables-services
• bc
• fontconfig

The installation is usually performed by executing yum:

yum install -y httpd
yum install -y mod_ssl
yum install -y mod_proxy_html
yum install -y curl
yum install -y wget


yum install -y unzip
yum install -y iptables
yum install -y iptables-services


yum install -y bc
yum install -y 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 && systemctl status httpd.service

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
