=== Installation instructions for CentOS 7 ===
# It may be advisable to obtain the <u>latest version</u> of the CentOS 7 Full Installation DVD since there may be improvements since the last version from when you took OSL740OPS235.<br><br>
# Download and burn on a DVD a copy of the CentOS 7 installation DVD (64 bit edition) from the CentOS web site or the Belmont server.<br>'''Note:''' we'll be using the 64 bit version of CentOS because all of our lab computers are equipped with Intel 64 bit mainboards and CPUs, and any computer you bought in the last few years for yourself will be 64bit as well.<br><br>
#* '''Seneca's mirror of CentOS:''' https://mirror.senecacollege.ca/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-2009.iso <br>This is very fast, but is only accessible from within Seneca's network - you can't access this from home. You can burn this disc on the machines in the Open Lab.)<br><br>
<li>'''Turn on networking''' and use '''host''' as the '''hostname'''.
<li>Under software selection, choose '''Gnome desktop'''.
<li>The partition setup is similar to what you had in OSL740OPS235:
<ul>
<li>Delete any old partitions.
At this point you have a basic Centos system installed and updated. This will serve as a host for the virtual machines where you will do the majority of the work in this course. All the rest of our labs will assume you have this basic system running. If, for any reason, your system becomes corrupted during the semester, you'll have to redo this lab to be able to continue with the remaining uncompleted labs. You are responsible for YOUR system. If you do not perform back-ups you have taken this risk on yourself. Poor planning on your part does not constitute an emergency for anyone else.

==INVESTIGATION 2: VIRTUAL MACHINE INSTALLATION==
# Create a new virtual machine named '''vm1'''.
# Accept the default file type (which is '''qcow2'''). You are <u>NOT</u> required to specify the VM file pathname as you did in OSL740OPS235.

{{Admon/important |Backup your VMs!|You MUST backup ALL of your VMs whenever you complete your '''OPS335 labs''' or when working on your '''OSL840 OPS335 assignments''':<br>[ [https://wiki.cdot.senecacollege.ca/wiki/OPS235_Lab_2_-_CentOS7_-_HD2#Part_1:_Backing_Up_Virtual_Machines Backing up Your Virtual Machines] ]. Refer to OPS235 lab2 notes on how to backup your VMs. You should backup your VMs to a USB key in case something happens to your host machine. Note: VM files contained in the '''/var/lib/libvirt/images''' directory have the extension in '''.qcow2''' and instead of '''.img''' (eg. for OPS235 courses prior to Fall 2016.}}
