Summary
This chapter was a summary of topics that we believe should be mentioned to any system administrator willing to administrate CentOS 7. We started by presenting a way to easily access multiple machines from one place. We saw how to protect services, and it is a kind of best practice to make sure that the server is configured and secured. Then we presented a way to share data across multiple servers, which is very useful for both the installation phase and daily usage. Finally, we covered how to monitor our services' activities on both the system and the network.
The job of a system administrator varies from time to time. Sometimes it gets easier and sometimes it gets harder, especially during a new installation. So, we have covered those tools that help soften the hard times and make them more manageable.
We believe that this book is equivalent to Mastering Red Hat or Scientific Linux, which are resources that are very much in demand in the field of Linux system administration...
