This is the first of what will be a number of posts on building out parts of a basic mission network. This network will be based on Centos 7 (Linux), with an IPA server (Linux version of Active Directory), have a local patching server, and a number of there features. Today’s article will focus entirely on the basic build of a Centos 7.0 system and will serve as the base system for all of the other lessons in the future. It is important to note that some of the configuration settings listed in the article will change in future article based on the purpose of the system (primarily disk partitions).
I will be building each of these systems as virtual machines using KVM on a Centos 7.0 system but the steps are pretty much the same when using VMWare or a bare metal system. We will make the following assumptions for this article:
- Domain Name: test.lab
- IPA Server IP Address: 192.168.1.254
- IPA Server Name: auth.test.lab
4. Configure the region to “Etc” and City to “Greenwich Mean Time”
6C. When the screen updates it will have 3 partitions in it (/boot, /, and swap).
6D. Change the space in / to 2 Gib (this is just temporary) and click out of that partition to free up space
6E. Create the following partitions (Note: These are minimums. Additional partitions or more space may be required for certian uses)
- /boot 1 Gib
- Swap 2 Gib (but more may be required for some uses)
- /home 1 Gib
- /tmp 1 Gib
- /var 4 Gib
- /var/log 2 Gib
- /var/log/audit 1 Gib
7. Select “Network & Host Name”
7A. Click the “On” button next to the interface name (This will tell the system to turn on the interface on boot).
7B. Enter the computers fully qualified domain name (i.e. servername.test.lab) and click “Apply”
7C. Click on the “Configure” button
7D. Change “Method” to manual (static IP address)
7E. Enter the IP address, subnet mask, and default gateway
7F. Enter the IP address for the IPA server under “DNS Servers”
7G. Enter test.lab under “Search Domains” and press “Save”
