How It Affects Your App
MySQL 1129 ER_HOST_IS_BLOCKED indicates that the host is blocked from connecting to the MySQL server. This can have a significant impact on an application, as it will be unable to access the database and any data stored in it. This can lead to errors in the application, as it will be unable to retrieve the necessary data. Additionally, the application may be unable to perform any database operations, such as inserting, updating, or deleting data. This can lead to unexpected behavior and a poor user experience.
How To Fix
1. Check the error log for the MySQL 1129 error. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
2. Check the user privileges for the user that is trying to connect. This can be done by running the following command:
mysql> SELECT USER(), CURRENT_USER();
3. Check the hostname of the server. This can be done by running the following command:
mysql> SELECT @@hostname;
4. Check the MySQL configuration file for any incorrect settings. This can be done by running the following command:
mysql> SHOW VARIABLES LIKE '%host%';
5. Check the MySQL server logs for any errors. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'log_error';
6. Check the firewall settings to ensure that the MySQL port is open. This can be done by running the following command:
mysql> SHOW GLOBAL VARIABLES LIKE 'port';
7. Check the MySQL user table for any incorrect settings. This can be done by running the following command:
mysql> SELECT * FROM mysql.user;
8. Finally, it is recommended to use an automated database observability tool to monitor and fix the MySQL 1129 in question.
