How It Affects Your App
This error indicates that the MySQL slave skip counter cannot be set in GTID mode. This means that the application cannot use the skip counter to skip transactions when replicating from the master to the slave. This can cause replication to be slower and more prone to errors, as the application will have to replicate all transactions instead of skipping some. Additionally, the application may not be able to replicate certain transactions, which can lead to data inconsistencies between the master and the slave.
How To Fix
1. Check the error log for the MySQL 1858 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 for any suspicious activity:
$ mysqladmin -u root -p processlist
4. Check the MySQL user table for any suspicious users:
$ mysql -u root -p -e "SELECT User, Host FROM mysql.user;"
5. Check the MySQL grant tables for any suspicious grants:
$ mysql -u root -p -e "SELECT * FROM mysql.db;"
6. Check the MySQL system variables for any misconfigurations:
$ mysql -u root -p -e "SHOW VARIABLES;"
7. Check the MySQL status variables for any misconfigurations:
$ mysql -u root -p -e "SHOW STATUS;"
8. Check the MySQL log files for any suspicious activity:
$ tail -f /var/log/mysql/mysql.log
9. Check the MySQL slow query log for any slow queries:
$ tail -f /var/log/mysql/slow.log
10. Check the MySQL binary log for any suspicious activity:
$ mysqlbinlog /var/log/mysql/mysql-bin.log
11. Check the MySQL error log for any suspicious activity:
$ tail -f /var/log/mysql/error.log
12. Check the MySQL performance schema for any misconfigurations:
$ mysql -u root -p -e "SELECT * FROM performance_schema.setup_consumers;"
13. Check the MySQL system tables for any suspicious activity:
$ mysql -u root -p -e "SELECT * FROM mysql.user;"
14. Check the MySQL system tables for any suspicious grants:
$ mysql -u root -p -e "SELECT * FROM mysql.db;"
15. Check the MySQL system tables for any misconfigurations:
$ mysql -u root -p -e "SELECT * FROM mysql.tables_priv;"
16. Check the MySQL system tables for any suspicious users:
$ mysql -u root -p -e "SELECT * FROM mysql.user_privileges;"
17. Check the MySQL system tables for any suspicious grants:
$ mysql -u root -p -e "SELECT * FROM mysql.db_privileges;"
18. Check the MySQL system tables for any misconfigurations:
$ mysql -u root -p -e "SELECT * FROM mysql.columns_priv;"
