MySQL5 绿色版安装教程
内容提要:mysql-noinstall-5.0.67-win32.zip的安装教程
一、下载,这里使用绿色解压缩版
[url]http://mysql.west.mirrors.airband.net/Downloads/MySQL-5.0/mysql-noinstall-5.0.67-win32.zip[/url]
二、配置MySQL5的参数
1、解压缩绿色版软件到D:\mysql-5.0.67-win32
2、修改D:\mysql-5.0.67-win32\my-small.ini文件内容,添加红色内容
[client]
#password = your_password
port = 3306
socket = /tmp/mysql.sock
default-character-set=gbk
[mysqld]
port = 3306
socket = /tmp/mysql.sock
default-character-set=gbk
skip-locking
key_buffer = 16K
max_allowed_packet = 1M
table_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K
port = 3306
socket = /tmp/mysql.sock
default-character-set=gbk
skip-locking
key_buffer = 16K
max_allowed_packet = 1M
table_cache = 4
sort_buffer_size = 64K
read_buffer_size = 256K
read_rnd_buffer_size = 256K
net_buffer_length = 2K
thread_stack = 64K
3、安装MySQL5的服务,服务名自己定义为MySQL5.
1)、在DOS窗口下进入D:\mysql-5.0.67-win32\bin目录
2)、执行安装MySQL服务名的命令:
D:\mysql-5.0.67-win32\bin>mysqld --install MySQL5 --defaults-file=D:\mysql-5.0.67-win32\my-small.ini
Service successfully installed.
3)、启动MySQL5服务
D:\mysql-5.0.67-win32\bin>net start mysql5
MySQL5 服务正在启动 .
MySQL5 服务无法启动。
MySQL5 服务正在启动 .
MySQL5 服务无法启动。
4)、登陆MySQL5服务器
D:\mysql-5.0.67-win32\bin>mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.0.67-community MySQL Community Edition (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
注意:MySQL5的管理员用户名为root,密码默认为空。
5)、查看数据库
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| test |
+--------------------+
3 rows in set (0.02 sec)
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| test |
+--------------------+
3 rows in set (0.02 sec)
可以看到MySQL服务器中有三个数据库。
6)、使用数据库
mysql> use test
Database changed
Database changed
7)、查看数据库中的表
sql> show tables;
Empty set (0.00 sec)
sql> show tables;
Empty set (0.00 sec)
8)、创建表ttt
mysql>
create table ttt(a int,b varchar(20));
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
9)、插入三条数据
mysql>
insert into ttt values(1,'aaa');
Query OK, 1 row affected (0.02 sec)
Query OK, 1 row affected (0.02 sec)
mysql>
insert into ttt values(2,'bbb');
Query OK, 1 row affected (0.00 sec)
Query OK, 1 row affected (0.00 sec)
mysql>
insert into ttt values(3,'ccc');
Query OK, 1 row affected (0.00 sec)
Query OK, 1 row affected (0.00 sec)
10)、查询数据
mysql>
select * from ttt;
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
+------+------+
3 rows in set (0.00 sec)
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | bbb |
| 3 | ccc |
+------+------+
3 rows in set (0.00 sec)
11)、删除数据
mysql>
delete from ttt where a=3;
Query OK, 1 row affected (0.01 sec)
Query OK, 1 row affected (0.01 sec)
删除后查询操作结果:
mysql>
select * from ttt;
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | bbb |
+------+------+
2 rows in set (0.00 sec)
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | bbb |
+------+------+
2 rows in set (0.00 sec)
12)、更新数据
mysql>
update ttt set b = 'xxx' where a =2;
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
查看更新结果:
mysql>
select * from ttt;
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | xxx |
+------+------+
2 rows in set (0.00 sec)
+------+------+
| a | b |
+------+------+
| 1 | aaa |
| 2 | xxx |
+------+------+
2 rows in set (0.00 sec)
13)、删除表
mysql>
drop table ttt;
Query OK, 0 rows affected (0.00 sec)
Query OK, 0 rows affected (0.00 sec)
查看数据库中剩余的表:
mysql>
show tables;
Empty set (0.00 sec)
Empty set (0.00 sec)
三、更改MySQL5数据库root用户的密码
1、使用mysql数据库
mysql>
use mysql
Database changed
Database changed
2、查看mysql数据库中所有的表
mysql>
show tables;
+---------------------------+
| Tables_in_mysql |
+---------------------------+
| columns_priv |
| db |
| func |
| help_category |
| help_keyword |
| help_relation |
| help_topic |
| host |
| proc |
| procs_priv |
| tables_priv |
| time_zone |
| time_zone_leap_second |
| time_zone_name |
| time_zone_transition |
| time_zone_transition_type |
| user |
+---------------------------+
17 rows in set (0.00 sec)
+---------------------------+
| Tables_in_mysql |
+---------------------------+
| columns_priv |
| db |
| func |
| help_category |
| help_keyword |
| help_relation |
| help_topic |
| host |
| proc |

| time_zone_name |
| time_zone_transition |
| time_zone_transition_type |
| user |
+---------------------------+
17 rows in set (0.00 sec)
3、删除mysql数据库中用户表的所有数据
mysql>
delete from user;
Query OK, 3 rows affected (0.00 sec)
Query OK, 3 rows affected (0.00 sec)
4、创建一个root用户,密码为“xiaohui”。
mysql>
grant all on *.* to
root@'%'
identified by 'xiaohui' with grant option;
Query OK, 0 rows affected (0.02 sec)
Query OK, 0 rows affected (0.02 sec)
5、查看user表中的用户
mysql>
select User from user;
+------+
| User |
+------+
| root |
+------+
1 row in set (0.00 sec)
+------+
| User |
+------+
| root |
+------+
1 row in set (0.00 sec)
6、重启MySQL5:更改了MySQL用户后,需要重启MySQL服务器才可以生效。
D:\mysql-5.0.67-win32\bin>
net stop mysql5
MySQL5 服务正在停止..
MySQL5 服务已成功停止。
MySQL5 服务正在停止..
MySQL5 服务已成功停止。
D:\mysql-5.0.67-win32\bin> net start mysql5
MySQL5 服务正在启动 .
MySQL5 服务已经启动成功。
7、重新登陆MySQL5服务器

D:\mysql-5.0.67-win32\bin>
五、操作数据库数据的一般步骤
1、启动MySQL服务器
2、登陆数据库服务器
3、使用某个要操作的数据库
4、操作该数据库中的表,可执行增删改查各种操作。
5、退出登陆。
