Chapter 5 Advanced Installation 163
This table provides a list of just some of the locations of important system files that you can use to configure and verify how the system is functioning. Knowing the location of the files and what they are used for will aid you in quickly troubleshooting a system when problems arise.
The Final Test of the Installation
2.19 Validate that an installed application is performing correctly in both a test and a production environment
At this point, you have installed the system and additional software, and you have checked that the system and its logs are functioning. You need to complete the final testing of the system, which usually means that the system is ready to be deployed into a production environment. You should have documented everything that you have done to the system. Your documentation should include the checklists that you used to install the system, all the hardware that you included, the partitioning scheme that you used, and the networking configurations, packages, and other system configurations, and any other packages that you installed before deployment. This documentation should provide a system history that will make it easy for others to follow what has been done and how to resolve issues that may arise. After you have completed this documentation, it’s time to give the end user access to the system. This is the final stage of testing, because the end user will be able to try and perform their daily functions which tests proper system functionality. If no issues arise during final testing, the system is fully functional. This completes the installation of Linux and the deployment into the production environment.
