- 修改密码
在5.7版本不太友好,密码要求比较严格
如果你想要设置一个简单的测试密码的话，比如设置为root，会提示这个错误，报错的意思就是你的密码不符合要求
警告：由于密码将以明文形式发送到服务器，请使用ssl连接以确保密码安全。
➜ tools mysqladmin -u root -p password "xxxxx"
Enter password:
mysqladmin: [Warning] Using a password on the command line interface can be insecure.
Warning: Since password will be sent to server in plain text, use ssl connection to ensure password safety.
mysqladmin: unable to change password; error: 'Your password does not satisfy the current policy requirements'
