一、MySQL密码的查看方法
- 通过配置文件查看MySQL密码
在Linux系统中，MySQL的配置文件通常位于/etc/mysql/my.cnf。您可以使用以下步骤查找并查看MySQL密码：
```bash
sudo grep 'password' /etc/mysql/my.cnf
```
在配置文件中，您可能会找到类似以下内容的行：
```ini
[mysqld]
password = yourpassword
```
请注意，这种方法仅适用于root用户的密码。
- 使用打印变量命令查看MySQL密码
打开终端并输入以下命令：
```bash
sudo mysql -uroot -p -e "SHOW VARIABLES LIKE 'password'"
```
在输入密码后，系统会显示类似以下结果：
```sql
+-----------------------+--------------------------------------------------------------+
| Variable_name | Value |
+-----------------------+--------------------------------------------------------------+
| password | *A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A8A
