Prerequisites

•  Make sure you have reviewed the following KB https://eis-vss.atlassian.net/wiki/spaces/VSSPublic/pages/1889697894/UTORrecover+-+NetWorker+TCP+IP+and+Firewall+Checklist#TCP/IP-Requirements
•  Access to the ITS Private Cloud (VSS) Users Storage (https://vskey-stor.eis.utoronto.ca)
•  Ensure that the PATH variable for the root and user accounts contains the /usr/sbin directory.
•  If the SELinux on your Linux system is in “enforcing” mode then you must change is to “permissive” by running the command: setenforce permissive

🐧 Linux x64 Installation Package Requirements

The NetWorker installation for all supported x64 Linux operating systems and versions requires two packages that the default OS installation might not include:

•   compat-libstdc++-33-3.2.3-68.1.x86_64.rpmor later
•  compat-libstdc++-33-3.2.3-68.1.i686.rpm or later

🤠 RHEL 7 and later and CentOS Package Requirements

Manually download and install the following Linux OS packages. The NetWorker installation fails when these packages do not exist on the host:

•  ksh
•  glibc.i686 0:2.17-55.el7 or later
•  nss-softokn-freebl.i686 0:3.15.4-2.el7 or later
•  libncursesw.so.5

🦎 SuSE Package Requirements

When you use the rpm command to install the NetWorker software, the installation displays a list of missing required operating system packages. You must install the required packages before you install the NetWorker software.

...

Default Directory Locations

Before you install the NetWorker software, you should become aware of the default directory locations and space requirements for the binary files, the databases, and the log files on the target host.

/usr/lib
/usr/sbin
/usr/bin
/opt/nsr

/usr/share

📁 Changing the Default Directory Locations

To store the configuration, log, and database files on file system that has more free disk space than the / file system, create a symbolic link from a new directory to the /nsr directory.

...

2. Create another /nsr directory on a disk with sufficient space. For example:

   Code Block
   mkdir /disk3/nsr

3. Link the new directory to the /nsr directory, by typing the following command:

   Code Block
   ln -s /disk2/nsr /nsr

\uD83D\uDCD8 Instructions

1. Log in to the target host and promote your account to super user.

2. Verify the contents of /etc/hosts contains an entry for the IPv4 loopback address and the first entry is the hostname, i.e.:

   Code Block
   27.0.0.1 host host-alias host.subdomain.utoronto.ca localhost

3. Fetch the installer from the VSS Users Storage with SCP or an equivalent SCP/SFTP client using the following settings:

   1. host: vskey-stor.eis.utoronto.ca

   2. VSS username and password.

4. Navigate to /ut-vss-lib/networker/pub/networker/LINUX as shown below. Then download the right installer for your OS architecture.

...

12. Start the networker client process with:

    1. for systemd based:

       Code Block
       systemctl start networker

    2. for sysvinit based:

       Code Block
       /etc/init.d/networker start

13. Check the status with:

    1. for systemd based:

       Code Block
       systemctl status networker

    2. for sysvinit based:

       Code Block
       /etc/init.d/networker status

14. If you change SELinux value, you must revert the SELinux to default value, that is, the value before the installation of RPMs.

15. Submit a request to backups@eis.utoronto.ca to with the following data:

    1. Hostname: hostname command.

    2. Fully Qualified Domain Name (FQDN)

    3. IP Address.

    4. Path(s) to Protect. i.e. /etc, /var, /home

16. Submit an echo request by following this link How-to check NetWorker client connectivity for UTORrecover.

17. The echo request result should be marked as Processed to be successful.
