1.远程联winNT下的MYSQL3.23.47-nt
[net@hsa1b ~]$ mysql -u root -p mysql -h 192.168.2.1
Enter password:
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 134 to server version: 3.23.47-nt

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

2.远程联Redhat8下的MYSQL3.23.56
mysql>
[net@hsa1b ~]$ mysql -u monty -p mysql -h 192.168.2.98
Enter password:

3.在Redhat8主机上联自己的MYSQL却可以
[root@red1 bin]# ./mysql -u monty -p mysql -h 192.168.2.98
Enter password:

我的REDHAT8下的MYSQL只可在本机上联，却不能远程联，为什么？
