How difference between use localhost/127.0.0.1 and 192.168.1.100 in this case. I don't know how to connect to this database from another machine.
Help please. Thank.

If all the previous answers didn't give any solution, you should check your user privileges.
If you could login as root to mysql
then you should add this:
CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY '***';
GRANT ALL PRIVILEGES ON * . * TO 'root'@'192.168.1.100' IDENTIFIED BY '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;
Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.
111 means connection refused, which in turn means that your mysqld only listens to the localhost interface.
To alter it you may want to look at the bind-address value in the mysqld section of your my.cnf file.
If you're running cPanel/WHM, make sure that IP is whitelisted in the firewall. You will als need to add that IP to the remote SQL IP list in the cPanel account you're trying to connect to.
