# service openstack-nova-conductor restart

# service openstack-nova-cert restart

# service openstack-nova-consoleauth restart

# service openstack-nova-novncproxy restart

The neutron section refers to the service name listed below:

[root@node-9 ~] # chkconfig-- list | grep neutron

Neutron-dhcp-agent0:off1:off2:on3:on4:on5:on6:off

Neutron-l3-agent0:off1:off2:on3:on4:on5:on6:off

Neutron-lbaas-agent0:off1:off2:off3:off4:off5:off6:off

Neutron-metadata-agent0:off1:off2:on3:on4:on5:on6:off

Neutron-openvswitch-agent0:off1:off2:on3:on4:on5:on6:off

Neutron-ovs-cleanup0:off1:off2:on3:on4:on5:on6:off

Neutron-server 0:off1:off2:on3:on4:on5:on6:off

The specific command is service + above the service name + restart, which will not be repeated here.

Finally, you can use the following command to check whether there are missing services that have not been restarted. Generally speaking, the above restart command should be sufficient. Some processes are not critical and can not be restarted, depending on your needs.

[root@node-9 ~] # chkconfig-- list | grep openstack
