Installing Network Activator on Both Central and Regional Servers

You perform the complete installation process from the central server. First you install Network Activator on the central server, and then, from the central server, you install Network Activator on the regional servers.

Before you install Network Activator:

1. Create the VMs on the central and regional servers with the resources specified in Software Requirements for Network Activator and VM Requirements for Network Activator.
2. Configure NTP on the central and regional servers.
3. Configure the firewall rules specified in Firewall Rules for VM on Central server and Firewall Rules for VMs on Regional server and for the VMs on the central and regional servers.
4. On each VM, configure DNS and connectivity to the Internet.
5. From each VM, verify that you can ping the IP addresses and hostnames of the physical servers, including the management server.

1. Log in to the VM on the central server as root.

   The current directory is the home directory.

2. Copy the installer package to this directory.
3. Expand the installer package, which has a name specific to the release. For example, if the name of the installer package is nsa-version.tar.gz:
   root@host:~/# tar –xvf nsa-version.tar.gz

   The expanded package is a directory that has the same name as the installer file, such as nsa-version, and contains two other installation packages with the extension .tar.gz.

   For example:

   • cas-version.tar.gz
   • container-details-version.tar.gz
4. Create a directory for Network Activator.
   root@host:~/# mkdir -p /cas
5. Access the directory that you created.
   root@host:~/# cd /cas
6. Expand the cas-version.tar.gz package to this directory.
   root@host:~/cas/# tar –xzvf ./nsa-version/cas-version.tar.gz
7. Copy the container-details-version.tar.gz package to this directory.
   root@host:~/cas/# cp ./nsa-version/container-details-version.tar.gz .
8. Expand the container-details-version.tar.gz package.
   root@host:~/cas/# tar –xzvf container-details-version.tar.gz

   Caution: Do not delete the container-details-version.tar.gz package from this directory. Doing so may cause the installation of Network Activator to fail.

9. Install Network Activator on the central server.
   root@host:~/cas/# ./config_box.sh central

   The installation begins and you see status messages about the installation.

10. From the same directory, install Network Activator on the regional servers.
    root@host:~/cas/# ./config_box.sh regional

    The installation begins on the regional servers and you see status messages about the service.

11. Follow the instructions on the screen to provider information about the regional servers.

    A status message indicates that the installation process is complete. The process also creates one X.509 certificate for each regional server in the /etc/pki/tls/certs directory. The name of each certificate has the format:

    regional-server-IP-Address.crt

12. (Optional) After the installation is complete, view the log files for the installation, and look for error messages that indicate any issues.

    For example:

    root@host:~/cas/# cd regions

    root@host:~/cas/regions# ls

    region-one   region-two   region-three

    root@host:~/cas/regions/# cd region-one

    root@host:~/cas/regions/region-one# tailf config_box.log

After the installation is complete, you next perform the setup procedures, then add the regional server to the Redirect Tool.
