============================
etcd doesn't start
------------------
.. code-block:: sh
[root@archlinux ~]# systemctl start etcd
Job for etcd.service failed because the control process exited with error code.
See "systemctl status etcd.service" and "journalctl -xe" for details
possible solution
~~~~~~~~~~~~~~~~~
Try :code:`cat /etc/hosts` if its output contain the following
.. code-block:: sh
127.0.0.1 localhost.localdomain localhost
::1 localhost localhost.localdomain
then unfortunately, we can't help you. But, if it doesn't contain the
above you can put the above in :file:`/etc/hosts` to fix the issue.
