Installation is a process of installing the software on target hardware platform. The installer installs everything necessary to run the softswitch, which includes operating system, all software components and necessary configuration files. It consists of the few simple steps outlined below.
First thing to do is to prepare installation media, which could be either CD or DVD disk. To do so download the ISO image file, save it on the local computer and burn it to the blank CD or DVD media using your favorite CD-burning software. Example or such software is Nero Burning ROM on Windows. Make sure to enable "Check Disk After Burning" option (or equivalent) to make sure the data can be read back from the CD.
Booting Installation Media
The next step is to boot your target hardware off from installation media. Usually this involves inserting installation media into CD or DVD drive and powering on the hardware. Sometimes, it might require going to the BIOS and making changes to the boot order. Please refer to your hardware manual for details.
The following screenshots illustrate selection of the boot media from the BIOS menu followed by the "Press any key to boot from the CD" prompt.
Once the installation program has been loaded, which usually takes up to 5 minutes, it will show the welcome screen below. Press Next to proceed.
On the next screen the system will allow you to change amount of disk space allocated for each logical partition and swap file. Usually default values should be accepted, unless there is a particular reason to make any adjustments. Please note that /var partition should get most of the disk space, since it contains database data as well as SIP log files. Press Next when finished to proceed.
The next menu allows to configure the network interface. Please refer to your network administrator or hosting provider for correct values.
If the hardware device that you are installing on has more than one network interface, then they will all be listed. You must choose the correct interface that is appropriately connected to your network. If a interface has no cable connected, then an exclamation mark "!" will appear in-front of the interface name. You can see an example of this in Network Configuration screenshot below. interface em1 is not connected.
Press Next when finished to proceed.
Time Zone Configuration
The next screen allows selecting server-wide time zone. This will be the time zone in which all log files are created. Generally, it is good idea to set it to match location of your head office, to simplify further log inspection. You can move between region selection list on the left and country/city selection list on the right using right and left arrow keys. Use Tab key to select Next button when done.
Users and Passwords Configuration
On the next menu the installation program allows you to set password for the UNIX system administrator shell account (root) as well as to create one non-privileged user shell account and set password for it. The root shell account is needed to perform various maintenance tasks in the system and inspect system logs, while non-privileged user is necessary in order to be able to login into server remotely using SSH (secure socket shell) protocol. By default, for security reasons, root user is only allowed to log in from local console. Once logged in, it is possible to switch between non-privileged user and root using "su" command. Make sure you remember both passwords and click Next button when finished.
Disk Formatting Confirmation
The next screen is the last page displayed before the installation program performs full formatting of the selected hard drive. At this point no changes have been made to your server yet, so it is the last chance to go back and select another disk or adjust some parameters. Press next when you are ready to install.
Installation Progress Display
On the next screen the installation program will be displaying progress of installation. Usually it takes somewhere from 3 to 15 minutes to complete (depending on hardware and type of installation media). When installation has been finished the installation program will display confirmation message and wait for the user to press Enter or Space key to reboot machine into the newly installed Softswitch.
When the system reboots please make sure to remove installation media from the CD/DVD drive. It is also a good idea to check BIOS settings to see that the disk where you have installed the software is the first one in the boot order. Please refer to your hardware manual on how to enter the BIOS and check/modify boot order. If everything has been configured correctly, the system should boot to the "login:" prompt as illustrated on the following screenshots.
