mysql初始化密码常见报错问题

1，mysql5.6是密码为空直接进入数据库的，但是mysql5.7就需要初始密码

cat /var/log/mysqld.log | grep password

2，然后执行 mysql -uroot -p ，输入上面的到的密码进入，用该密码登录后，必须马上修改新的密码，不然会报如下错误：

mysql> use mysql;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

3，如果你想要设置一个简单的测试密码的话，比如设置为123456，会提示这个错误，报错的意思就是你的密码不符合要求

mysql> alter user 'root'@'localhost' identified by '123456';
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
