iMC Monitor Deployment Agent cannot be opened, but the web page can be opened

Null

Customer feedback iMC monitor deployment agent can not be opened, but the web page can be opened, monitor deployment agent reported an error.

1. Prompted by the error report can not connect to the service, but imc login page can be opened, and the authentication business is normal, indicating that the process is in a normal state of availability; 

2. Check iMC/deploy/dma.log log found the following error, suggesting that the connection can not be localhost: 61626 ports

3. iMC connects to the corresponding ports by parsing the /etc/hosts file. Checking the hosts file, we found that the first line of the file, which should normally be 127.0.0.1, has been replaced by the actual node ip, which prevents IMC from connecting to localhost to access the local system.

Change the hosts file to the correct 127.0.0.1 and the monitoring deployment agent can be opened.

Please do not modify the hosts file arbitrarily.
