使用

1. systemctl start mysqld 启动mysql
2. grep password /var/log/mysqld.log 查看密码
3. 登录mysql
4. 修改密码

➜  tools grep password /var/log/mysqld.log
2022-09-18T04:02:24.435856Z 1 [Note] A temporary password is generated for root@localhost: YeBPgBelw3_O
➜  tools mysql -uroot -PYeBPgBelw3_O
mysql: [ERROR] Unknown suffix 'Y' used for variable 'port' (value 'YeBPgBelw3_O')
mysql: [ERROR] mysql: Error while setting value 'YeBPgBelw3_O' to 'port'
➜  tools mysql -uroot -p YeBPgBelw3_O
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
➜  tools mysql -uroot -pYeBPgBelw3_O

4. 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'

修改设置密码的策略

➜  tools mysql -uroot -pYeBPgBelw3_O
mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.

mysql>  set global validate_password_length=1;

mysql> exit
Bye

再次设置密码成功

➜  tools mysqladmin -u root -p password "xxxxx"
Enter password:   #输入原始密码
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.
