How to install a R1Soft CDP agent on an AlmaLinux 8 server

This tutorial describes how to install the R1Soft agent on an AlmaLinux 8 server. The R1Soft agent requires an R1Soft Server software to be installed on a separate server.

MANUAL INSTALLATION:

Step 1: Update all packages to the latest version.

dnf update

Step 2: Install the kernel-headers package

dnf install kernel-headers

Step 3: Insert the following into a new repository file /etc/yum.repos.d/r1soft.repo

[r1soft]
name=R1Soft Repository Server
baseurl=http://repo.r1soft.com/yum/stable/$basearch/
enabled=1
gpgcheck=0

Step 4: Install the R1Soft Serverbackup agent

dnf install serverbackup-agent

Step 5: Install the R1Soft Kernel module

serverbackup-setup --get-module

If you see the following error, proceed to Step 5.1  If not, proceed to Step 6.
Get module failed.
Falling back to old get-module …
exit status 1

Step 5.1: Stop the CDP agent

/etc/init.d/cdp-agent stop

Step 5.2: Visit the following URL to download an AlmaLinux 8 R1Soft beta kernel module for your kernel: http://beta.r1soft.com/modules/AlmaLinux_8_x64/

/etc/init.d/cdp-agent stop

Step 5.3: Download the file that matches your kernel version to /lib/modules/r1soft. Change the URL below to your matching kernel version.

Change the wget URL below to your matching kernel version from the repo above. If it does not exist, you can revert your kernel to an earlier version or try opening a ticket with R1Soft.

cd /lib/modules/r1soft
wget http://beta.r1soft.com/modules/AlmaLinux_8_x64/hcpdriver-cki-4.18.0-305.10.2.el8_4.x86_64.224.ko

Step 6: Start the CDP Agent

/etc/init.d/cdp-agent start

Step 7: Verify the R1Soft module loaded

modinfo /lib/modules/r1soft/hcpdriver*

Congratulations, you can now add your R1Soft agent to your R1soft CDP server
