HomeDatabaseMysql Tutorialmysql免安装制作使用说明

mysql免安装版本的制作方法,需要的朋友可以参考下。

1>把压缩文件mysql-noinstall-5.1.6-alpha-win32.zip解压到一个目录下,在环境变量中设置MYSQL_HOME,把%MYSQL_HOME%\bin 加入到 path。

2>创建my.ini配置文件,内容如下:[mysqld]#设置basedir指向mysql的安装路径basedir=...\mysqldatadir=...\mysql\data my.ini文件放在系统文件下面。

3>启动与停止mysqlmysqld.exe --install(安装windows服务,卸载使用mysqld.exe --remove )启动:net start mysql停止:net stop mysql

4>连接mysql格式: mysql -h主机地址 -u用户名 -p用户密码例1:连接到本机上的mysqlmysql -uroot -p例2:连接到远程主机上的mysqlmysql -h110.110.110.110 -uroot -pabcd123

5>退出mysql命令exit(回车)或者quit(回车)

6>修改密码格式:mysqladmin -u用户名 -p旧密码 password 新密码例:给root加个密码ab12。首先在DOS下进入目录mysqlbin,然后键入以下命令mysqladmin -uroot password ab12注:因为开始时root没有密码,所以-p旧密码一项就可以省略了。2、 例2:再将root的密码改为djg345。mysqladmin -uroot -pab12 password djg345下面的是mysql环境中的命令, 以分号作为命令结束

7>增加新用户格式:grant select on 数据库.* to 用户名@登录主机 identified by "密码";例1、增加一个用户test1密码为abc,让他可以在任何主机上登录, 并对所有数据库有查询、插入、修改、删除的权限。首先用以root用户连入mysql,然后键入以下命令:grant select,insert,update,delete on *.* to test1@"%" Identified by "abc";例2、增加一个用户test2密码为abc,让其只可以在localhost上登录, 并可以对数据库mydb进行查询、插入、修改、删除的操作(localhost指本地主机, 即mysql数据库所在的那台主机),这样用户即使用知道test2的密码,也无法从internet上直接访问数据库,只能通过mysql主机上的web页来访问了。grant select,insert,update,delete on mydb.* to test2@localhost identified by "abc";

8>显示数据库列表show databases;

9>显示库中的数据表use mysql;//数据库名称show tables;

10>显示数据表的结构describe 表名;

11>建库create database 库名;

12>建表use 库名;create table 表名( ......

MySQL: String Data Types and CollationsMySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.
