How It Affects Your App
This error indicates that the MySQL server is currently running a purge operation on the binary log. This can have a significant impact on the application as it can cause queries to take longer to execute, or even fail. Additionally, the application may experience a decrease in performance due to the purge operation. It is important to monitor the server for this error and take appropriate action to ensure the application is running optimally.
How To Fix
1. Check the error log for the MySQL 1868 error:
$ tail -f /var/log/mysql/error.log
2. Check the MySQL configuration file for any misconfigurations:
$ cat /etc/mysql/my.cnf
3. Check the MySQL process list to see if there are any processes that are running that shouldn't be:
$ mysqladmin -u root -p processlist
4. Check the MySQL user table to see if there are any users that shouldn't have access:
$ mysql -u root -p -e "SELECT User, Host FROM mysql.user;"
5. Check the MySQL grants table to see if there are any grants that shouldn't be in place:
$ mysql -u root -p -e "SELECT * FROM mysql.db;"
6. Check the MySQL privileges table to see if there are any privileges that shouldn't be in place:
$ mysql -u root -p -e "SELECT * FROM mysql.user_privileges;"
7. Once all of the above steps have been completed, restart the MySQL server:
$ service mysql restart
8. Finally, it is recommended to use an automated database observability tool to monitor and fix the MySQL 1868 in question. This tool can provide real-time insights into the performance and health of the database, as well as alerting when any issues arise. This can help to quickly identify and fix any issues that may arise in the future.
