When installing the Agent software on Linux machines
that you want to protect, use the following guidance. After installation
is complete, configure the Agent as described in the topic “Configuring
the Rapid Recovery Agent on a Linux machine” in the
Dell Data Protection
| Rapid Recovery 6.0 Installation and Upgrade Guide
.
-
CAUTION: After configuring the newly installed Agent software on a Linux machine,
restart the machine. Restarting ensures that the proper kernel driver
version is used to protect your machine.
The method for installing and removing the Agent software on Linux
machines has changed. As of release 6.0.1, the following factors apply:
-
One set of instructions
applies to installations of Agent on a Linux machine with current
access to the Internet. This is referred to as online installation.
Instead of using shell scripts, package managers are used to install
or remove the Rapid Recovery software from a repository referenced
on the local Linux machine.
-
NOTE: The repository
is used for staging of files for the relevant package managers. This
repository is not related to the Rapid Recovery repository.
-
If installing Agent on
a Linux machine with no access to the Internet (such as an air-gapped
or secured standalone machine), this is referred to as offline installation.
For this process, you must first download an installation package
from a Linux machine with Internet access, and then move those installation
files to the secured computer for installation.
Because the various supported Linux distributions
use different package managers for online installation, the procedure
for installing, upgrading, or removing Agent on any supported Linux
OS depends on the package manager used. The package managers, and
the Linux distributions they support, are described in the following
table.
Table 1. Package managers
and the Linux distributions they support
Package Manager |
Linux Distribution |
yum |
Linux distributions based on Red Hat
Enterprise Linux (RHEL), including RHEL, CentOS, and Oracle Linux.
|
zypper |
SUSE Linux Enterprise Server (SLES)
versions 11, 12
|
apt |
Linux distributions based on Debian,
including Debian 7 or 8, and Ubuntu 12.04 and later
|
As a one-time setup step for each Linux
machine, you must configure your local software repository to point
to the location where the package manager obtains Dell Rapid Recovery
installation files.
-
NOTE: This process is represented
by steps 1 through 4 in each of the installation procedures. When
upgrading future editions of the Rapid Recovery Agent on a Linux
machine with the repository configured, you will not need to perform
these steps.
After you configure a software
repository on your Linux machine, the package manager is able to retrieve
and install the packages needed for installation or removal of Rapid
Recovery Agent software and related components, such as aamount (now
called local mount), aavdisk (now called rapidrecovery-vdisk), and
Mono (an open source, Ecma standard-compliant, .NET Framework-compatible
tool set used for porting the Agent software to Linux platforms).
For each package manager, you can run the
appropriate command at the command line to determine if it is configured
to download Rapid Recovery packages. These commands are listed in
the following table.

package manager repository configuration

Previous versions of the
AppAssure Agent software must be
completely removed from a Linux machine before installing the Rapid
Recovery Agent version and protecting the Linux machine using the
Rapid Recovery Core. This is true for online or offline installations.
Removing AppAssure Agent employs the use of shell scripts. The uninstall
instructions differ, depending on the Linux distribution you are using.
For more information on uninstalling AppAssure Agent from a Linux
machine, see the topic “Uninstalling the AppAssure Agent software
from a Linux machine” in the
Dell Data Protection | Rapid Recovery
6.0 Installation and Upgrade Guide
.
-
NOTE: Removal of the new
Rapid Recovery Agent
software uses the package manager for each distribution. Therefore,
if uninstalling a version of Rapid Recovery Agent, see the appropriate
procedure under the topic see the topic “Uninstalling the AppAssure
Agent software from a Linux machine” in the
Dell Data Protection
| Rapid Recovery 6.0 Installation and Upgrade Guide
.
If installing Rapid Recovery Agent on a Linux
machine that has never had AppAssure Agent installed, determine the
appropriate package manager from the preceding table. Then follow
the appropriate installation procedure.
After configuring the newly installed Agent software on a Linux machine,
you must restart the machine. Restarting ensures that the proper kernel
driver version is used to protect your machine.
Thus, the installation process when upgrading from AppAssure
to Rapid Recovery involves:
-
Removing
the AppAssure Agent software (not required for first-time installations)
-
Determine the relevant
package manager for your Linux distribution
-
Follow the
procedure for installing Rapid Recovery Agent on the Linux machine,
including configuring the software repository (steps 1 through 4 of
the installation procedure)
-
Run the
configuration utility to set port, configure users, add firewall exclusions,
install the kernel module, and start the Agent service.
-
Restart the Linux machine
The instructions for installing the Agent
software on a Linux machine differ slightly depending on the Linux
distribution you are using. For more information about preparing for
and installing the Agent software for a Linux machine connected to
the Internet, see the appropriate topic. You can choose from the following
