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-        | controller | internal | enabled | up    | 2016-12-20T0 |
   |    | consoleauth  |            |          |         |       | 0:44:48.0000 |
   |    |              |            |          |         |       | 00           |
   |  5 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
   |    | scheduler    |            |          |         |       | 0:44:48.0000 |
   |    |              |            |          |         |       | 00           |
   |  6 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
   |    | conductor    |            |          |         |       | 0:44:54.0000 |
   |    |              |            |          |         |       | 00           |
   |  9 | nova-compute | compute    | nova     | enabled | up    | 2016-10-21T0 |
   |    |              |            |          |         |       | 2:35:03.0000 |
   |    |              |            |          |         |       | 00           |
   +----+--------------+------------+----------+---------+-------+--------------+
   

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   |
   +----+--------------+------------+----------+---------+-------+--------------+
   |  4 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
   |    | consoleauth  |            |          |         |       | 0:44:48.0000 |
   |    |              |            |          |         |       | 00           |
   |  5 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
   |    | scheduler    |            |          |         |       | 0:44:48.0000 |
   |    |              |            |          |         |       | 00           |
   |  6 | nova-        | controller | internal | enabled | up    | 2016-12-20T0 |
   |    | conductor    |            |          |         |       | 0:44:54.0000 |
   |    |              |            |          |         |       | 00           |
   |  9 | nova-compute | compute    | nova     | disabled| up    | 2016-10-21T0 |
   |    |              |            |          |         |       | 2:35:03.0000 |
   |    |              |            |          |         |       | 00           |
   +----+--------------+------------+----------+---------+-------+--------------+
   

4. Enable the service:

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