昨天才装的！
MySQL-server-4.0.26-0.i386.rpm
MySQL-shared-4.0.26-0.i386.rpm
MySQL-client-4.0.26-0.i386.rpm
MySQL-devel-4.0.26-0.i386.rpm
装的这四个！可是登陆不去呀！
[root@SERVER_KNL ~]# mysqladmin -u root -p  create twig
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user: [email="'root@localhost'"]'root@localhost'[/email] (Using password: YES)'
救我呀！谢谢昂！

Make sure you have a correct password for root first, then specify a IP address with parameter '-h' and try again.

楼上高手，我装了MYSQL没做任何的改动！请教教我怎么做才能让我的mysql用起来！谢谢！

telnet localhost 3306
如果提示连接拒绝，说明 mysql 服务器没有启动，

楼上兄弟我按你的方法
[root@SERVER_KNL wang]# telnet localhost 3306
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
NHost 'localhost.localdomain' is not allowed to connect to this MySQL serverCon
nection closed by foreign host.
好像是说没有启动吧！
但是我启动这个MYSQL.SERVER这个文件也没反应
[root@SERVER_KNL wang]# find / -name mysql.server -print
/usr/share/mysql/mysql.server
[root@SERVER_KNL wang]# /usr/share/mysql/mysql.server start
没反应！

Connected to localhost.localdomain
它提示你已经连接到mysql 服务器了，

Host 'localhost.localdomain' is not allowed to connect to this MySQL server.
它阻止了来自 localhost.localdomain 的访问，
使用
mysql -u root -h 你本机的IP地址 -p
来进行网络登陆吧

楼上！
[root@SERVER_KNL wang]# mysql -u root -h 192.168.0.25 -p
Enter password:
ERROR 1130: Host '192.168.0.25' is not allowed to connect to this MySQL server
是说不能登陆！分析下！谢谢！请问你的MSN是多少，我想加你请教你下LINUX方面的问题！我的MSN是
[email="wang2004yong7@hotmail.com"]wang2004yong7@hotmail.com[/email]谢谢！

你没有安装完全吧，
初始化数据库没有？ 运行 mysql/bin/mysql_install_db

楼上！
我运行
mysql/bin/mysql_install_db
说没有这个文件或目录！我安装的我已说了！
MySQL-server-4.0.26-0.i386.rpm
MySQL-shared-4.0.26-0.i386.rpm
MySQL-client-4.0.26-0.i386.rpm
MySQL-devel-4.0.26-0.i386.rpm
这四个文件！
