一.初始化

1.mysql初始化

mysqld --initialize-insecure --

mysql -u root

set password =password('123456'); 

2.修改端口后登入

mysql -P3396 -uroot -p 

 3.允许mysql远程登入

mysql -u root -p 

mysql>use mysql; 

mysql>update user set host = '%' where user = 'root'; 

mysql>select host, user from user; 

 创建管理员用户 -- use mysql   @  '%'  可以远程连接  既可以远程登入又可以创建表格

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON *.* TO 'estar'@'%' IDENTIFIED BY 'Jxestar999' WITH GRANT OPTION;

删除一个用户:

mysql >      Delete FROM user Where User='test' and Host='localhost';

mysql>         flush privileges;

4.注册到服务器

mysqld -install mysqlCwp --defaults-file="d:\mysql5.1\my.ini"

5.删除服务

mysqld   --remove  mysql(服务名字)

 二. 设置字符集, 防止中文乱码

1.设置中文字符

[client]

default-character-set=utf8 

2. jdbc访问地址

url= jdbc:mysql://groupServer2:3306/drawmysql?useUnicode=true&characterEncoding=UTF-8
