更改mysql密码的时候，出现如下错误是什么意思？

我的也是这种情况
初始化mysql:
/usr/local/mysql/script/mysql_install_db
然后safe_mysqld --user=root &之后就提示
Starting mysqld daemon with databases from /usr/local/var
031116 11:04:05  mysqld ended


[1]+  Done                    safe_mysqld
然后用mysqladmin -u root -p password 12345的时候就会出现:
Enter password:
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!
请问怎么解决啊!!!
