Manage Compute services

You can enable and disable Compute services. The following examples disable and enable the nova-compute service.

1. List the Compute services:

   $ openstack compute service list
   +----+----------------+------------+----------+---------+-------+----------------------------+
   | ID | Binary         | Host       | Zone     | Status  | State | Updated At                 |
   +----+----------------+------------+----------+---------+-------+----------------------------+
   |  4 | nova-scheduler | controller | internal | enabled | up    | 2016-12-20T00:44:48.000000 |
   |  5 | nova-conductor | controller | internal | enabled | up    | 2016-12-20T00:44:54.000000 |
   |  8 | nova-compute   | compute    | nova     | enabled | up    | 2016-10-21T02:35:03.000000 |
   +----+----------------+------------+----------+---------+-------+----------------------------+
   

2. Disable a nova service:

   $ openstack compute service set --disable --disable-reason "trial log" compute nova-compute
   +----------+--------------+----------+-------------------+
   | Host     | Binary       | Status   | Disabled Reason   |
   +----------+--------------+----------+-------------------+
   | compute  | nova-compute | disabled | trial log         |
   +----------+--------------+----------+-------------------+
   

3. Check the service list:

   $ openstack compute service list
   +----+----------------+------------+----------+---------+-------+----------------------------+
   | ID | Binary         | Host       | Zone     | Status  | State | Updated At                 |
   +----+----------------+------------+----------+---------+-------+----------------------------+
   |  5 | nova-scheduler | controller | internal | enabled | up    | 2016-12-20T00:44:48.000000 |
   |  6 | nova-conductor | controller | internal | enabled | up    | 2016-12-20T00:44:54.000000 |
   |  9 | nova-compute   | compute    | nova     | disabled| up    | 2016-10-21T02:35:03.000000 |
   +----+----------------+------------+----------+---------+-------+----------------------------+
   

4. Enable the service:

   $ openstack compute service set --enable compute nova-compute
   +----------+--------------+---------+
   | Host     | Binary       | Status  |
   +----------+--------------+---------+
   | compute  | nova-compute | enabled |
   +----------+--------------+---------+
