How It Affects Your App
MySQL 3006 ER_BINLOG_UNSAFE_FULLTEXT_PLUGIN indicates that the application is using a full-text plugin that is not safe for replication. This can lead to data inconsistency between the master and slave databases, which can cause data loss or corruption. It can also lead to application errors, such as incorrect search results or incorrect data being displayed. In addition, it can cause performance issues due to the extra overhead of replicating the full-text plugin.
How To Fix
1. Check the error log for the MySQL 3006 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 any processes are running that could be causing the error:
$ mysqladmin -u root -p processlist
4. Check the MySQL user privileges to see if any users have been granted too many privileges:
$ mysql -u root -p -e "SELECT User, Host, Password FROM mysql.user;"
5. Check the MySQL database tables for any corruptions:
$ mysqlcheck -u root -p --all-databases
6. Use an automated database observability tool to monitor and fix the MySQL 3006 error. Automated database observability tools can help identify the root cause of the error and provide recommendations on how to fix it. They can also monitor the database for any future errors and alert the user when they occur.
