Cannot create PoolableConnectionFactory (Access denied for user 'api_test'@'223.198.171.138' (using password: YES))这个为什么会报错

这个错误是因为在尝试连接到数据库时，使用的用户名和密码不正确或没有正确的权限来访问数据库。可能是以下问题之一：

1. 用户名和密码不正确：请确保使用的用户名和密码是正确的，并且已授权访问数据库。

2. IP地址被拒绝：如果您的数据库设置了IP地址过滤器，则可能需要将IP地址添加到白名单中。

3. 数据库权限不足：如果您的用户没有足够的权限来访问数据库，则需要授予足够的权限。

请检查以上几点，找到问题并解决它。

Cannot create PoolableConnectionFactory (Access denied for user 'api_test'@'223.198.171.138' (using password: YES))

This error message indicates that the user "api_test" is being denied access to the database from IP address "223.198.171.138" using the provided password.

Possible causes and solutions:

1. Incorrect username or password: Double-check that the username and password are correct and have the necessary privileges to access the database.

2. IP address not allowed: Check if the IP address of the client making the connection is allowed in the database server's firewall rules or in the user's account settings.

3. Database permissions: Verify that the user "api_test" has the necessary permissions to access the database.

4. Connection string errors: Check for any typos or syntax errors in the database connection string.

5. Network issues: Check for any network-related issues, such as connectivity or firewall problems, that may be preventing the connection from being established.

In summary, ensure that the user has the correct credentials and permission to access the database, the IP address is whitelisted, and there are no network or syntax issues.

Cannot create PoolableConnectionFactory (Access denied for user 'root'@'10.10.56.113' (using password: YES))

这个错误信息表示在使用jmeter连接数据库时，出现了访问被拒绝的问题。具体错误是"Cannot create PoolableConnectionFactory (Access denied for user 'root'@'10.10.56.113' (using password: YES))"。这个错误通常是由于数据库连接配置的问题导致的。

解决这个问题的方法是确保数据库连接配置正确。根据引用[2]中的示例，你可以尝试授权用户'root'@'10.10.56.113'访问数据库的权限。你可以使用以下命令来授权用户：

grant all privileges on your_database_name.* to 'root'@'10.10.56.113' identified by 'your_password';
flush privileges;

请确保将"your_database_name"替换为你实际的数据库名称，将"your_password"替换为你实际的密码。这样做后，重新尝试连接数据库，应该就能够成功了。
