MySQL添加用户、删除用户与授权

1.新建数据库

mysql> create database testDB default character set utf8;

2.创建用户

mysql> GRANT USAGE ON *.* TO 'test123'@'%' IDENTIFIED BY 'test123' WITH GRANT OPTION;

3.用户授权

3.1 授权test用户拥有testDB数据库的所有权限

mysql> GRANT ALL PRIVILEGES ON testDB.* TO 'test123'@'%' IDENTIFIED BY 'test123';

3.2 授权部分权限

mysql>grant select,update on testDB.* to ‘test123’@‘%’ identified by 'test123';
mysql>flush privileges;

4. 删除用户和数据库

mysql>Delete FROM user Where User='test123' and Host='%';
mysql>flush privileges;
mysql>drop database testDB;

5.设置表名不区分大小写

vi /usr/local/mysql/my.cnf

#在mysql节点下加
lower_case_table_names=1
