Installing Linux for HP Opencall

The first phase of software installation is to install a distribution of the Linux operating system with which the HP OpenCall SS7 software is compatible. This section provides guidelines for this installation. For details of the installation procedure, you must refer to the user documentation for the appropriate distribution of Linux.

Refer to the HP OpenCall SS7 3.1 on Linux Release Notes for an up-to-date list of the supported distributions of Linux.

	NOTE: Once you have completed the installation described in this section, you must install the relevant components of the HP Opencall Enablement Kit. This is described in “Installing HP Opencall Enablement Kit Components for Linux”.If you have an HP server on which Linux has been pre-installed for use with HP Opencall, you must omit this section and continue to the installation of the HP OpenCall SS7 software, described in “Installing HP OpenCall SS7 3.1 on Linux”.

In order to install your chosen distribution of Linux, follow the guidelines given below in conjunction with the user documentation for the relevant Linux distribution. Note that not all the guidelines may be relevant to all distributions.

Installation Type

For the Red Hat 7.3 distribution, select an installation of type “Server”.

Disk Partitioning

You must partition your hard disk and assign mount points to the partitions as shown below:

Boot Loader

Select a boot loader of the type “LILO”.

Host Name

Replace the default hostname with your own choice of hostname.

Firewall

Choose to have no firewall.

User Account

Set up a user account with username ocadmin.

Definition of the User and Group ocadmin

Even when the Network Information Service (NIS) is used to define user ocadmin and group ocadmin,the ocadmin user’s home directory must always be located in a local /home/ocadmin directory not on the auto-mounted network file system (NFS). In this case, the HP OpenCall SS7 installer does not create a new ocadmin user and group but installs the files in the existing user account.

If NIS is not used, HP OpenCall SS7 creates a local ocadmin user and local ocadmin group on your system.
