mysql5.7初始化密碼報錯 ERROR 1820 (HY000): You must reset your password using ALTER USER statement before

mysql初始化密碼常見報錯問題

1，然后執行 mysql -uroot -p ，輸入上面的到的密碼進入，用該密碼登錄后，必須馬上修改新的密碼，不然會報如下錯誤：

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

2，如果你想要設置一個簡單的測試密碼的話，比如設置為123456，會提示這個錯誤，報錯的意思就是你的密碼不符合要求

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