How It Affects Your App
MySQL 1130 ER_HOST_NOT_PRIVILEGED indicates that the user is not allowed to connect to the MySQL server from the host they are attempting to connect from. This can have a significant impact on an application as it can prevent the application from accessing the necessary data from the MySQL server. This can lead to the application not functioning properly or not being able to access certain features. Additionally, it can lead to data loss or corruption if the application is unable to access the necessary data.
How To Fix
1. Check the error log for the MySQL 1130 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 firewall settings to ensure that the port used by MySQL is open. This can be done by running the following command:
mysql> SHOW VARIABLES LIKE 'port';
6. Check the network settings to ensure that the server is reachable from the client. This can be done by running the following command:
mysql> SHOW VARIABLES LIKE 'net_read_timeout';
7. Check the MySQL server status to ensure that it is running. This can be done by running the following command:
mysql> SHOW GLOBAL STATUS;
8. As a final step, it is recommended to use an automated database observability tool to monitor and fix the MySQL 1130 in question. This tool can provide real-time visibility into the performance and health of the database, as well as alerting when issues arise. It can also provide detailed insights into the root cause of the issue, allowing for faster resolution.
