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
