mysql免安装版的实际配置方法_MySQL
bitsCN.com
以下的文章主要向大家讲述的是MySQL 免安装版的实际配置方法,其免安装版本可在相关网站下载,下载之后可将其解压到c:/MySQL获取他任意位置,解压后在目录下,找到my-huge.ini,my-large.ini,my-medium.ini配置文件。
打开进行配置:
[MySQLd]
# set basedir to your installation path
basedir=c:/MySQL
# set datadir to the location of your data directory
datadir=c:/mydata/data
MySQL 免安装版配置方法中我们需要设置MySQL的字符集,gbk或utf-8,根据需要
# set character set
default-character-set=gbk
# set character collation
default-collation=gbk_chinese_ci
保存后另存为my.ini
最后在开始->运行里
c:/MySQL/bin/> MySQLd --install MySQL --defaults-file=C:/my.ini
c:/MySQL/bin/> NET START MySQL
就ok了,默认帐户root,密码空。
以上的相关内容就是对MySQL 免安装版配置方法的介绍,望你能有所收获。
下面是其他网友的参考:
以mysql-noinstall-5.1.6(win32)为例
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=.../mysql
datadir=.../mysql/data
my.ini文件放在系统文件下面
XP系统在C:/windows目录下,2000系统在C:/winnt下
3>启动与停止mysql
mysqld-nt.exe --install(安装windows服务,卸载使用mysqld-nt.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mysql
mysql -uroot -p
例2:连接到远程主机上的mysql
mysql -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符
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(字段设定列表);
13>删库和删表
drop database 库名;
drop table 表名;
14>将表中记录清空
delete from 表名;
15>显示表中的记录
select * from 表名;
例:
drop database if exists school; //如果存在SCHOOL则删除
create database school; //建立库SCHOOL
use school; //打开库SCHOOL
create table teacher //建立表TEACHER
(
id int(3) auto_increment not null primary key,
name char(10) not null,
address varchar(50) default '深圳',
year date
); //建表结束
//以下为插入字段
insert into teacher values('','glchengang','深圳一中','1976-10-10');
insert into teacher values('','jack','深圳一中','1975-12-23');
注:在建表中
(1) 将ID设为长度为3的数字字段:int(3),并让它每个记录自动加一: auto_increment,
并不能为空:not null,而且让它成为主字段primary key
(2) 将NAME设为长度为10的字符字段
(3) 将ADDRESS设为长度50的字符字段,而且缺省值为深圳。varchar和char有什么区别
呢,只有等以后的文章再说了。
(4) 将YEAR设为日期字段。
如果你在mysql提示符键入上面的命令也可以,但不方便调试。 你可以将以上命令
原样写入一个文本文件中假设为school.sql,然后复制到c:下,并在DOS状态进入目录
mysql in,然后键入以下命令:
mysql -uroot -p密码 如果成功,空出一行无任何显示;如有错误,会有提示。(以上命令已经调试,你
只要将//的注释去掉即可使用)。
16>将文本数据转到数据库中
1、 文本数据应符合的格式:字段数据之间用tab键隔开,null值用来代替。例:
3 rose 深圳二中 1976-10-10
4 mike 深圳一中 1975-12-23
2、 数据传入命令load data local infile "文件名" into table 表名;
注意:你最好将文件复制到mysql in目录下,并且要先用use命令?硭

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.
