=== Bootstrapping a new machine to a static ip === | |||
<nowiki> | |||
Login to the new install and find it's ip, make sure you know the root password, or have an sshkey for the root account. | |||
Choose a hostname for your new machine. | |||
Log in to boole, and as root cd /etc/bind, and edit lan.london.hackspace.org.uk. and 24.31.172.in-addr.arpa. to add your new host, remember the new static ip you choose. | |||
There is only a few static ip's left, you may end up needing to shrink the dhcp range and change the dhcpserver config on boole as well. | |||
zkt-signer -v -r to sign and push out your changes. | |||
Check that the hostname works in fwd and reverse dns. | |||
and git commit your changes and log out of boole. | |||
on denning edit /etc/ansible/hosts, add: | |||
<ip> syslocation="something" lhs_host=<hostname> | |||
to at least [lhshosts], you probably want [ldap-clients] as well, and maybe some other sections, depending on what you want. | |||
then edit /etc/ansible/lhs/vars/defaults.yml , adding your host and the last octet of the new static ip to the hosts: section | |||
now ssh to the host to check that ssh works: | |||
ssh root@<ip> | |||
You may need to fix old cached pub keys, and/or allowing root to ssh to your new machine with a password ( PermotRootLogin yes in /etc/ssh/sshd_config on the machine you are setting up). | |||
Now you can run ansible. This example assumes you are using a password for root | |||
cd /etc/ansible | |||
ansible-playbook -l "<ip>" -k -u root lhs/site.yml | |||
and hopefully ansible should run ok and set everything up! | |||
Note that ansible will change the root password, hopefully you've got a way to get back in (either you are an admin in ansible, or in the Admins group in ldap, in either case you can login as yourself and then sudo). | |||
Now reboot the new machine, it should come back with the static ip. double check that it's right. | |||
Now edit /etc/ansible/hosts on denning again and in the entries you added earlier change <ip> to the machines new full hostname. | |||
Now run ansible again (needed to fix the snmp config), if it's an ldap client you'll have to use your ldap password - (You could always add your ssh key to your account on the new machine). | |||
git commit your changes on denning. | |||
and you are done! | |||
