Minimal Install will install just the basic software and services required for basic setup and nothing extra. This way you can configure your server and packages, more on a monolithic side. (I am selecting Gnome Desktop, since I will be using GUI and I will not be using it in production).

12. From the resulting interface change file system to ext4 and click “Update Settings”.
13. Click on + and add another Mount Point (/). Enter Desired Capacity and Click “Add Mount Point”.
14. Again, from the resulting interface select ‘ext4‘ as file System and Click “Update Settings”.
15. Again Click on + icon and add another mount point (swap). Enter Desired capacity and click “Add Mount Point”.
16. Finally “Accept Changes” when prompted for disk format and create.
17. Back to the Installation Summary Interface. Now everything seems at its place. Click “Begin Installation”.
18. Now packages will start installing. Time to set Root Password and create a new user.
19. Enter Root password and click done.
20. Create a new user. Provide name, user_name and password. Click Done.
21. Complete!!! Time to reboot the machine.
22. After Successful Installation, here is the boot prompt and login screen.
23. The first Impression – Interface After successful login.
24. Check the release information.
For those who are not new to CentOS and have installed and using a previous version of CentOS can update it to latest point Release CentOS 7.1 (1503).
Upgrade CentOS 7.0 to CentOS 7.1
1. Make sure you have backup of everything. So that is anything goes bad you can just restore.
2. Have a stable Internet connection. You know you cant update with that ;)
3. Fire the below command.
# yum clean all && yum update OR # yum -y upgrade
Note: Using ‘-y‘ option with Yum is discouraged. You must review the changes that are going to take place in your system.
CentOS is so popular and so widely used as Sever Operating System. CentOS is a very stable, manageable, Predictable and reproducible derivative of Commercial RHEL. Available for free (as in terms of free in beer as well as free in speech) and a wonderful community support makes it very suited for Server platforms and General use. Nothing needs to be said after that and anything said past it is just a gossip.
That’s all for now. I’ll be here again with another interesting article. Till then stay tuned and connected to Tecmint. Don’t Forget to provide us with your valuable feedback in the comments below. Like and share us and help us get spread.
