1、MySQL下載地址。
www.mysql.com/downloads/mysql-4.0.html
下載MySQL 5.1版本的2個包（根據你的實際需求下載所需要的包）：
MySQL-server-community-5.1.68-1.rhel5.i386.rpm
MySQL-client-community-5.1.68-1.rhel5.i386.rpm
2、安裝server和client安裝包。
[root@serv22 mnt]# rpm -ivh MySQL-server-community-5.1.68-1.rhel5.i386.rpm

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h serv22 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test databases and anonymous user created by default.
This is strongly recommended for production servers.
See the manual for more instructions.
Please report any problems with the /usr/bin/mysqlbug script!

3、安裝完后直接運行 “mysql” 命令登陸數據庫，看是否安裝成功。
[root@serv22 mnt]# mysql

如果出現以上提示，說明安裝成功。
4、查看有哪些數據庫，系統會默認安裝幾個數據庫。
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| test |
+--------------------+
3 rows in set (0.00 sec)
使用mysql數據庫
mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
查看數據庫里有哪些表
mysql> show tables;
+---------------------------+
| Tables_in_mysql |

查看表的結構，比如user表。
mysql> desc user;

+-----------------------+-----------------------------------+------+-----+---------+-------+
39 rows in set (0.01 sec)
查看user表中的數據
mysql> select host,user from user;
+-----------+------+
| host

+-----------+------+
| 127.0.0.1 | root |
| localhost | |
| localhost | root |
| serv22 | |
| serv22 | root |
+-----------+------+
5 rows in set (0.00 sec)
--修改root用戶的密碼
格式：mysqladmin -u用戶名 -p舊密碼 password 新密碼
[root@serv22 mnt]# mysqladmin -uroot password mysql123
再次嘗試不加密碼登陸數據庫，會出現報錯信息
[root@serv22 mnt]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
使用密碼登陸數據庫
格式：mysql [-u username] [-h host] [-p[password]] [dbname]
[root@serv22 mnt]# mysql -uroot -pmysql123
