Investigation 3: Virtual Network & Machine Installation: - minor formatting changes
*Select '''Server with GUI''' as the installation type.
*The partition setup will be similar to what you had in previous OPS courses.
** Delete any old partitions on the drive.<br />** Provide a separate mount point for '''/var/lib/libvirt/images'' with at least 100GB.
*Set a good root password. No, not ‘P@ssw0rd’.
*Create a non-privileged user account using your MySeneca ID.
** If your MySeneca ID is long enough that typing it would be irritating to do on a regularbasis you may use an alternate name, but you must clear it with me first.
===On First Boot===
Make sure your machine meets the following conditions:
* Your NIC is set to automatically turn on when the machine does.
* Add a virtual interface to your existing one. Give it the '''static address 172.16.[x].1''', where x is the network number on blackboard.
* SELinux is set to '''enforcing'''.
* The machine must be fully updated.
* You may use either ''iptables'' or Use ''firewalld'' as your firewall.
* Install ''libvirt'' and ''virt-manager''. Set the virtualization service to start automatically when the machine boots.
* Reboot your machine
==Investigation 2: Basic Service Installation==
*Configure the postfix service on your host to send and receive email for your domain.
*Install bind and configure your host as the master DNS server for your domain.
** It must provide forward and reverse lookups of the machines in your domain.<br>** As the course goes on, you will add entries to your zone for the machines you create.<br>** Create an MX record to direct all mail sent to users @<yourdomain>.ops to your host.<br>** It must allow machines in your virtual network to access the outside world (e.g. to get updates).<br>*Ensure both services (postfix and named) start automatically when the machine boots, and allow the traffic for both through your firewall.
==Investigation 3: Virtual Network & Machine Installation==
*Remove the default virtual network.
*Create a new virtual network called opsnet.
** Address: 192.168.1[x].0/24, where x is the network number on blackboard. E.g. if your network number is 29, your opsnet network will be 192.168.12929.0/24.
* Disable DHCP, and allow forwarding to any physical device using NAT.
*Install a new vm using the same CentOS release as the host machine.
**You may wish to provide the VM access to more than 1 CPU and 1 GiB of RAM so it installs and updates faster.
* During the installation process:
**Set the hostname to blank.<yourdomain>.ops, using the same domain name as the host machine. **Provide your machine with a static address of your choice, using the host’s address for the primary DNS server and the gateway. **Set the timezone to Americas/Toronto. **Use a minimal installation (no GUI). **Set your root password, and create a non-privileged user account using your MySeneca ID.* If your MySeneca ID is long enough that typing it would be irritating to do on a regular basis you may use an alternate name, but you must clear it with me first.*Once the machine is installed, ensure it is fully updated.
*Shut down your VM, make sure the resource settings are reduced back to 1 CPU and 1 GiB of RAM.
*When you need a new VM, clone this one.
