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;

注意：此处的'%'，是指该用户可以远程登录，如果想本地登录的话，将"%"改为"localhost"。也可以指定某台机器可以远程登录。

 #

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
