You can install the software-only system layer of Avaya Hybrid Cloud Gateway on your RHEL OS.
Note:
Avaya Cloud Delivery is responsible for downloading and deploying Avaya Hybrid Cloud Gateway as part of the Avaya Experience Platform™ (On-Prem + Connect) service activation. Customers cannot download Avaya Hybrid Cloud Gateway from Avaya PLDS.
Before you begin
Ensure that RHEL 8.10 OS is deployed with a single network interface.
Note:
When deploying RHEL OS for Avaya Hybrid Cloud Gateway, on the Software Selection page, under Base Environment, ensure that you select Minimal Install.
Ensure that the RHEL instance has the correct footprint required by the Avaya Hybrid Cloud Gateway application:
Install the RHEL OS on Disk 1 with a minimum disk size of 50 GB. You must add four more disks, such as Disk 2, Disk 3, Disk 4, and Disk 5, and then create partitions.
To check the version of the installed RHEL, run the following command: cat /etc/system-release
Ensure that the RHEL disk partitions and the logical volumes of the disks are of the required sizes required by Avaya Hybrid Cloud Gateway. For more information about RHEL disk partitioning, see RHEL disk partition.
Ensure that you have a minimum of one non-root user.
For multiple non-root users, the system layer considers the first user in the ls/home list to be an admin user.
Ensure to add a local host entry for Avaya Hybrid Cloud Gateway in the /etc/hosts file.
Ensure to register the RHEL instance at the Red Hat subscription portal or create a local repository for RPM installation or updates.
Procedure
Ensure to log in to the RHEL instance as an administrator user.
Download the following file at the /home/admin location: AHCG-swonly-1.0.x.x.x.tgz or the latest swonly package.
To navigate to the admin folder, run the following command: cd /home/admin
To extract the software-only artifact, run the following command: tar -xzf AHCG-swonly-1.0.x.x.x.tgz
To navigate to the AHCG-swonly-1.0.x.x.x folder, run the following command: cd "AHCG-swonly-1.0.x.x.x"
To extract the ucapp-swonly-system-1.0.x.x.x.tgz file, run the following command: tar -xzf ucapp-swonly-system-1.0.x.x.x.tgz
To switch to the root user, run the following command: su
To navigate to the ucapp-swonly-system-1.0.x.x.x folder, run the following command: cd ucapp-swonly-system-1.0.x.x.x
To install the system layer, run the following command: ./swOnlyUpdate.sh --install
Enter values in the following fields when prompted and continue with the system layer installation:
Enable Enhanced Access Security Gateway (EASG) ? [yes|no]:yes or no
Please enter the correct NTP server IP/FQDN: NTP server IP/FQDN address
Provide AHCG profile to be deployed, small or large ? [small|large]: small or large
Depending on the network bandwidth, installing the required packages takes 5 to 10 minutes. The installer changes the name of the network interface to eth0 if the name is different.
RHEL reboots on successful installation of the system layer.
After the system reboots, log in as a root user and do the following:
To check the version of the system layer, run the following command: sys versions
To check the EASG details, run the following command: EASGProductCert --certInfo
You can use this command if you enable EASG during the installation process.
To install the dependent RPM files, download the following RPM files from the RHEL repository:
haveged-1.9.14-1.el8.x86_64.rpm
tomcat-native-1.2.23-1.el8.x86_64.rpm
To install the haveged-1.9.1-1.el8.x86_64.rpm file version or later, run the following command: rpm -i haveged-1.9.14-1.el8.x86_64.rpm
To install the tomcat-native-1.2.23-1.el8.x86_64 file version or later, run the following command: rpm -i tomcat-native-1.2.23-1.el8.x86_64.rpm
To restart the haveged services, run the following command: systemctl restart haveged
To check the status of the haveged service, run the following command: systemctl status haveged
Next Steps
You must repeat the steps in the above procedure for all nodes that are going to be a part of the Avaya Hybrid Cloud Gateway cluster.
