Linux Installation
4. Modify the LD_LIBRARY_PATH variable to specify the path to the /lib/nsr directory:
LD_LIBRARY_PATH=/ nw /lib/nsr
5. Create a symbolic link for the cst folder:
ln -s / nw /opt/nsr/cst /opt/nsr/cst
Changing the configuration, log, and database files directory
To change the default location of the configuration, logs, and database files, create a
symbolic link from the new directory to the /nsr directory.
For example:
1. Create another nsr directory on a disk with sufficient space:
mkdir /disk2/nsr
2. Link the new directory to the /nsr directory:
ln -s /disk2/nsr /nsr
Preparing the Linux target host
Before you install NetWorker, create a backup of the operating system configuration file
and configure the target host to support NetWorker.
◆ Create a backup copy of the operating system configuration files:
cp /etc/rpc /etc/rpc.orig
cp /etc/ld.so.conf /etc/ld.so.conf.orig
◆ Ensure that the PATH variable for the root and user accounts contains the /usr/sbin
directory.
◆ If you enabled SELinux on your system, add the file contexts and the security contexts
that the NetWorker software requires.
1. To add file contexts, type:
semanage fcontext -a -t textrel_shlib_t "/usr/lib/nsr/lib.*\.so"
2. To update the security contexts, type:
restorecon -R /usr/lib/nsr"

If the semanage or the restorecon file does not exist on the Linux system, install the
policycoreutils-python package.
