修改root本地登录密码

grep 'temporary password' /var/log/mysqld.log
mysql -uroot -p
set password for 'root'@'localhost'=password('!2Qw32sd');

注意：mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误

配置默认编码为utf8
修改/etc/my.cnf配置文件，在[mysqld]下添加编码配置，如下所示：

[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'

[远程连接腾讯云MySQL数据库]
输入mysql -uroot -p，使用Mysql
use mysql
update user set host = '%' where user = 'root'
select host ,user,password from user;
grant all privileges on . to 'root'@'%' identified by 'root' with grant option;
flush privileges;
