Question

我刚刚通过MySQL Package Installer安装了MySQL。安装完成后，显示以下消息：

2015-11-19T21:16:59.224430Z 1 [Note] A temporary password is generated for root@localhost: qXkd%pqb)6z3

If you lose this password, please consult the section How to Reset the Root Password in the MySQL reference manual.

然后我尝试使用Sequel Pro登录 127.0.0.1 / root /＃＆lt ;; Ay。

这就是结果：

Your password has expired. To log in you must change it using a client that supports expired passwords.

这是MySQL WorkBench的结果

Your connection attempt failed for user 'root' from your host to server at 127.0.0.1:3306:
  Your password has expired. Your instance of Connector/C++ is not linked against mysql client library that allows to change it. resetting of an expired password. To resolve this, you either need to change the password with mysql client that can do it or rebuild your instance of Connector/C++ against mysql client library that supports resetting of an expired password.

Please:
1 Check that mysql is running on server 127.0.0.1
2 Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed)
3 Check the root has rights to connect to 127.0.0.1 from your address (mysql rights define what clients can connect to the server and from which machines) 
4 Make sure you are both providing a password if needed and using the correct password for 127.0.0.1 connecting from the host address you're connecting from

所以我试过
