FB Revival

Steps to rise up a mirror of FruitBreedomics (FB) site

Set up your environment variables

Please set your environment in order that scripts could work:

export DIGITALOCEAN_ACCESS_TOKEN=<your DO token>

Create a droplet on Digital Ocean (DO)

Create a new droplet using:

$ python scripts/create_droplet.py

NB: time is needed to start-up a droplet and to add firewalls, volumes, etc. the script will exit if it can't perform a particoular action. Recall the script after the droplet is started to add additional configuration staff (the script make no changes if they currently applied on the droplet)

Update `hosts` file

Set the current droplet IP address in hosts file:

[fruitbreedomics]
centos7     ansible_host=fb.paolocozzi.cloud

Install all the roles:

$ ansible-playbook site.yml

The openvz_role was inspired from here

Create a new container

Ensure a container is not present:

# vzlist -a 101
Container not found

create a new container with

$ vzctl create 100 --ostemplate centos-6-x86_64
$ vzctl set 100 --ipadd 192.168.0.100 --save
$ vzctl set 100 --nameserver 8.8.8.8 --save
$ vzctl set 100 --hostname server100.mydomain.com --save

Modify memory used:

$ vzctl set 109 --ram 1024M --save

Start the container and enter into it

$ vzctl start 100
$ vzctl enter 100

More info on basic operations could be found here and here. Info on OpenVZ. Info on container NAT Info on changing memory here and here Info on iptables

Restoring FB machine:

$ vzdump --restore /mnt/fb_volume/fruitbreedomics/vzdump-openvz-109-2019_06_12-22_10_52.tar.gz 109
$ vzctl set 109 --netif_del eth0 --save
$ vzctl set 109 --ipadd 192.168.0.109 --save
$ vzctl start 109
