Dear,
I used the command:
firewall-cmd --zone = public --add-port = 8082 / tcp --permanent
on the backup server and fails. Does anyone tell me where I’m going wrong?
Hello,
Its just a warning as it says you already have that rule added.
I didn’t understand why there was a failure in the final result of the question
I used this resource to complete the task successfully. Have a look at it when you get a chance.
Hi @rodney
Since you used --permanent option while adding the rule so you must had to restart/reload firewalld service as rule was not actually saved.
I had the same issue , Task needs to be more clear.
