Etcd for Ubuntu
|
|
===============
|
|
|
|
OpenStack services may use Etcd, a distributed reliable key-value store
|
|
for distributed key locking, storing configuration, keeping track of service
|
|
live-ness and other scenarios.
|
|
|
|
Install and configure components
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
#. Install the ``etcd`` package:
|
|
|
|
.. code-block:: console
|
|
|
|
# apt install etcd
|
|
|
|
#. Edit the ``/etc/default/etcd`` file and set the ``ETCD_INITIAL_CLUSTER``,
|
|
``ETCD_INITIAL_ADVERTISE_PEER_URLS``, ``ETCD_ADVERTISE_CLIENT_URLS``,
|
|
``ETCD_LISTEN_CLIENT_URLS`` to the management IP address of the
|
|
controller node to enable access by other nodes via the management
|
|
network:
|
|
|
|
.. code-block:: none
|
|
|
|
ETCD_NAME="controller"
|
|
ETCD_DATA_DIR="/var/lib/etcd"
|
|
ETCD_INITIAL_CLUSTER_STATE="new"
|
|
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
|
|
ETCD_INITIAL_CLUSTER="controller=http://10.0.0.11:2380"
|
|
ETCD_INITIAL_ADVERTISE_PEER_URLS="http://10.0.0.11:2380"
|
|
ETCD_ADVERTISE_CLIENT_URLS="http://10.0.0.11:2379"
|
|
ETCD_LISTEN_PEER_URLS="http://0.0.0.0:2380"
|
|
ETCD_LISTEN_CLIENT_URLS="http://10.0.0.11:2379"
|
