在Redhat9.0下连结数据库出错的提示

执行目录在/usr/bin. 我先用chown -R root /var/lib/mysql
chgrp -R mysql /var/lib/mysql
我在提示符下执行：

已经搞定了
我用/usr/bin/mysql -h loclahost -u root -p
[root@linuxsir root]# /usr/bin/mysql -h localhost -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2 to server version: 3.23.54

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>

不过我用
[root@linuxsir root]# /usr/bin/mysql -h 172.27.231.231 -u root -p
Enter password:
ERROR 2003: Can't connect to MySQL server on '172.27.231.231' (113)
则不行，密码我都是用的空格，172.27.231.231是我在局域网里的IP
不晓得为什么不能通过呢，请兄弟们都研究一下，谢谢
