刚刚安装的mysql数据库给设置密码时报错，求解

[root@bogon mysql-5.5.23]# /usr/local/mysql/bin/mysqladmin -uroot password 123
/usr/local/mysql/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists!
[root@bogon mysql-5.5.23]#
求解

是由于你root帐号权限的问题。执行root 登录mysql，命令行mysql>GRANT ALL PRIVILEGES ON *.* TO ' root '@'%' identified by 'password';

string url="jdbc:mysql;//localhost:3306/jdbc";
其中分号改冒号就ok
