3# 修改root本地登录密码
mysql 首次启动，在/var/log/mysqld.log 文件中给 root 生成了一个临时密码。
通过下面的方式找到 root 临时密码，然后登录 mysql 进行修改：
[root@AndyCentOS7Basic forCentOS]# grep ‘temporary password’ /var/log/mysqld.log
2017-11-08T01:28:17.646798Z 1 [Note] A temporary password is generated for root@localhost: #L+rRHgQs2Oz1
登录并修改 root 密码：
[root@AndyCentOS7Basic forCentOS]# mysql -uroot -p#L+rRHgQs2Oz
mysql> ALTER USER ‘root‘@’localhost’ IDENTIFIED BY ‘mypassword’;
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements1

4mysql5.7 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
必须先改默认密码，才能做别的操作。
设置密码的验证强度等级，设置 validate_password_policy 的全局参数为 LOW 则密码可以设置得简单一点，输入设值语句 `set global validate_password_policy=LOW;` 进行设值，但这是临时性的，重启 MySQL 后失效。
mysql> show variables like ‘%password%’;
