mysql 配置 初始化

一.初始化

1.mysql初始化

mysqld --initialize-insecure --

mysql -u root

set password =password('123456'); 

2.修改端口後登入

mysql -P3396 -uroot -p 

 3.容許mysql遠程登入

mysql -u root -p 
mysql>use mysql; 
mysql>update user set host = '%' where user = 'root'; 
mysql>select host, user from user; 

 建立管理員用戶 -- use mysql   @  '%'  能夠遠程鏈接  既能夠遠程登入又能夠建立表格

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

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

刪除一個用戶:

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

mysql>         flush privileges;

4.註冊到服務器

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

5.刪除服務

mysqld   --remove  mysql(服務名字)

 二. 設置字符集, 防止中文亂碼

1.設置中文字符

[client]
default-character-set=utf8 

2. jdbc訪問地址

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