Batch Executing Commands on ECSs
Scenarios
COC provides unified operations on ECSs. You can submit script commands to one or more ECSs without login to quickly perform routine maintenance on them.
Precautions
You can perform this operation only when the selected instance is running.
The UniAgent instance must be running. For details, see Configuring UniAgent.
If the selected ECSs run on different OSs (Linux and Windows), you need to submit commands to the ECSs separately.
Executing a Command
- Log in to COC.
- In the navigation pane on the left, choose Resource O&M > Batch Resource Operations.
- On the displayed page, choose the Elastic Cloud Server (ECS) tab and click Execute Commands.
- Set Execute Commands.
