C.3.36. MySQL is incorrectly configured

Condition or Error

The configuration of MySQL was wrong; it included autocommit=0 and the wrong server-id

Causes

Rectifications

Edit my.cnf and clean up. Restart MySQL if possible. Alternatively, set manually:

mysql> set GLOBAL autocommit=1;
Query OK, 0 rows affected (0.00 sec)
 
mysql> set GLOBAL server_id=2;
Query OK, 0 rows affected (0.01 sec)
