After rebooting the host, you attempt to start the mysqld service. You get the following error:
Can’t start the server: Bind on TCP/ IP port: Address already in use
What is the most likely cause of this error?
A. The mysql service has already been started on the same port.
B. The network service process in the server is frozen, so all TCP/ IP connections are paused and
cannot be reused.
C. You failed to specify the port number 3306 to the command to start the server, so it is defaulting to port 80, which is in use by the built-in web server.
D. The /etc/hosts file does not have a valid IP entry for mysqld localhost, so it is binding to 127.0.0.1, which is already in use.
E. The mysql.sock file in the MySQL /tmp directory was not removed after the reboot, so mysqld still thinks there is an active server running.
