./bin/mysqladmin -u root password 'mysqladmin'//要先解決如下的異常，然後重啟伺服器
ln -s /usr/local/mysql/bin/mysql /usr/local/bin/mysql//一定要執行，不然不能使用mysql命令

--------------------------------------------------------------------
錯誤異常的解決：

[

[email protected] mysql]# ./bin/mysqladmin -u root password 'mysqladmin'
./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!

檢視/tmp資料夾的確沒有mysql.sock檔案，

通過find命令查詢

[

[email protected] /]# find / -name mysql.sock
/var/lib/mysql/mysql.sock

原來安裝到/var/lib/mysql/mysql.sock這個位置啦，我們需要修改my.cnf檔案

[[email protected] /]# vi /etc/my.cnf

[client]
port=3306
socket=/var/lib/mysql/mysql.sock

儲存之後即出，重新啟動mysql。
service mysql restart

mysql -uroot -p
use mysql;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mysqladmin' WITH GRANT OPTION;
FLUSH PRIVILEGES;
service mysql restart
