进入mysql
mysql -u root -p
修改mysql密码
mysql> ALTER USER ‘root‘@‘localhost‘ IDENTIFIED BY ‘new password‘;（直接设置密码不能过于简单）
可通过如下命令查看完整的初始密码规则
mysql>show variables like ‘validate_password‘;
可通过如下命令修改mysql> set global validate_password_policy=0;
配置权限
#任何主机
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION;
#指定主机
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘jack‘@’10.10.50.127’ IDENTIFIED BY ‘654321‘ WITH GRANT OPTION;
# 然后刷新权限
mysql>flush privileges;
修改mysql数据库总的user表使相的用户能从某一主机登录
mysql>use mysql;
mysql>update user set host = ‘%‘ where user = ‘root‘;
mysql>select host, user from user;
查看mysql的字符集
mysql>show variables like ‘character_set%‘;
