Prevailing wisdom is actually that this *can* help virtual hosts, especially when the VM guest has multiple CPUs. See: http://wiki.xen.org/wiki/Network_Throughput_and_Performance_Guide Signed-off-by: Alan Orth <alan.orth@gmail.com>
Ansible Playbook
Ansible playbook for base and initial configuration of web server hosting my personal websites. After successful execution of this playbook, however, there is still some manual work to import databases, copy site content, etc.
Assumptions
Before you can run this, a few things are assumed:
- You have a clean, minimal Ubuntu 14.04 host up and running
- You have a user account with password-less SSH access to the machine
- You have sudo privileges on the remote host
- You have created a
hostsfile with something like:
[web]
web01
Use
Once you've satisfied the the above assumptions, you can execute:
ansible-playbook web.yml -i hosts -K
Testing in a VM
A simple way to test locally in a virtual machine using libvirt + KVM:
sudo virt-install -n web01 -r 1024 --vcpus 2 -l http://ubuntu.mirror.ac.ke/ubuntu/dists/trusty/main/installer-amd64/ --os-type=linux --os-variant=ubuntusaucy --disk /home/aorth/software/vms/web01.qcow2,device=disk,bus=virtio,format=qcow2,size=40 --vnc --cpuset=1,2 -x "auto=true priority=critical url=http://blah.com/~aorth/preseed/public/ubuntu-14.04.cfg"
This boots from a network Ubuntu mirror, then uses a preseed to automate the OS installation.
