two。 Failed to enable ceph dashboard

Mgr module opened dashboard prompt error, although added-- force surface enabled, but the dashboard service is not actually started, because setting the dashboard user command prompt is not supported.

3. Problem troubleshooting process

Mgr node to view mgr startup log

But the pip installation ansible module cannot be installed alive or dead, and starting dashboard still prompts ImportError: No module named 'requests.packages.urllib3'

From the log, it seems that the ceph mgr enable module, in principle, python uses urllib3 to download and install it from the network, so change the direction, first solve the urllib3 module problem.

Pip uninstalls urllib3 and installs it using yum instead.

View the log when the dashboard module is enabled in real time again

Finally, dashboard was launched successfully without any error report.
