ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.99.100' (61)
$ mysqladmin -h192.168.99.100 --port=3306 version 127 ↵
mysqladmin: connect to server at '192.168.99.100' failed
error: 'Can't connect to MySQL server on '192.168.99.100' (61)'
Check that mysqld is running on 192.168.99.100 and that the port is 3306.
You can check this by doing 'telnet 192.168.99.100 3306'DEBUG的过程
