DRLM Client Installation
Since DRLM 2.0.0, DRLM clients (ReaR) can be installed and configured on a remote server from the DRLM server using drlm instclient
Let’s explain a little bit the steps this feature does:
Create the drlm user
Install ReaR dependencies
Install ReaR package
Configure ReaR to be managed by DRLM
Configure SUDO for drlm user
Start and configure required services
Supported OSs for instclient command
Unattended Client Installation has been tested on:
SLES (11, 12 & 15)
OpenSUSE (13, Leap 42, Leap 15)
RHEL & CentOS (5, 6, 7 & 8)
Debian (6, 7, 8, 9, 10 & 11)
Ubuntu LTS (12.04, 14.04, 16.04, 18.04, 20.04 & 22.04)
Note
It should work on other RedHat, Debian or SUSE variants.
Requirements
In order to install ReaR from DRLM server the client must have:
Access to EPEL Repo to install rear from repo (CentOS,RHEL)
instclient uses apt-get, yum and zypper, so repositories must be configured
SSH enabled
root user or user with administrator privileges to install, start services like rpcbind and configure ReaR, DHCP and sudo applications.
Run unattended install
To perform an unattended install of a DRLM client, just is needed to run instclient DRLM command like one of the following examples:
Warning
The client must be properly registered in DRLM with addclient command.
Examples:
~# drlm instclient -c ReaRCli1
~# drlm instclient -c ReaRCli1 -U http://download.opensuse.org/repositories/Archiving:/Backup:/Rear/Debian_7.0/all/rear_1.17.2_all.deb
