Setting up for installing Multi-Server Administration on a Linux server

You must perform the following tasks before installing TrueSight Network Automation – Multi-Server Administration on a Linux server:

Checking required disk space on a Linux server

Perform the following steps to check the required disk space on a Linux server:

1. Confirm that the drive where you plan to install the TrueSight Network Automation – Multi-Server Administration has at least 1.2 GB of free disk storage. Do not install the software on a network or NFS mounted drive. You must install the software on a local drive.
2. Confirm that the /tmp directory has at least 450 MB of free space.
3. If the /tmp directory does not have sufficient free space, you can run the following commands before installing to make the installation use an alternate temporary directory. The directory specified in this command must have at least 200 MB of free space available.
   $ IATEMPDIR=/your/free/space/tmp_directory
$ export IATEMPDIR
4. Verify that the server host computer has sufficient disk space, as discussed in System requirements.
   The installation uses /var/bca-networks-data as the default for the location of the dynamic data for the application.
   As an alternative, you can install the BCA-Networks-Data directory into a separate partition that meets the disk space requirements.

5. Configure the following permissions:

   Directory	Permissions	Octal Value
   Installation directory	rwx rwx rwx	777
   Temp or alternate directory	rwx rwx rwx	777
   Parent directories of the temp or alternate directory	rwx rwx r-x	775

Configuring the hosts file

Confirm that the /etc/hosts file has at least two entries.

• Assign 127.0.0.1 to localhost.

  Warning

  If 127.0.0.1 is not assigned to localhost, installation would fail.

• Assign the static IP address of the server to the server hostname.
  
  

  127.0.0.1 localhost
  10.1.2.3 msa-server-01

Library requirements

This section discusses the library requirements.

Confirming the availability of libXtst.so and libXrender.so

If you are installing on a 64-bit version of Linux, confirm that both 32-bit and 64-bit version of the following libraries are available:

• libXtst.so: Confirm that the library is available by executing the following command:
  

  locate libXtst.so

  The following output is seen if both 32-bit and 64-bit version of the library are available:

  [root@bna tmp]# locate libXtst.so
  /usr/lib/libXtst.so.6
  /usr/lib/libXtst.so.6.1.0
  /usr/lib64/libXtst.so.6
  /usr/lib64/libXtst.so.6.1.0

  If the library is not available and yum is configured on a Red Hat Linux system, you can install 32-bit and 64-bit version of the library by using the following command:

  yum install libXtst libXtst.i686

• libXrender.so: Confirm that the library is available by executing the following command:
  
  locate libXrender.so
  

  The following output is seen if both 32-bit and 64-bit version of the library are available:

  [root@bna tmp]# locate libXrender.so
  /usr/lib/vmware-tools/lib32/libXrender.so.1
  /usr/lib/vmware-tools/lib32/libXrender.so.1/libXrender.so.1
  /usr/lib/vmware-tools/lib64/libXrender.so.1
  /usr/lib/vmware-tools/lib64/libXrender.so.1/libXrender.so.1
  /usr/lib64/libXrender.so
  /usr/lib64/libXrender.so.1
  /usr/lib64/libXrender.so.1.3.0

  If the library is not available and yum is configured on a Red Hat Linux system, you can install 32-bit and 64-bit version of the library by using the following command:

  yum install libXrender libXrender.i686

Other library requirements

Ensure that the nslookup library is available by executing the following command:

locate nslookup

If not installed, and yum is configured on a Red Hat Linux system, then install the library by executing the following command:

yum install nslookup
