As well as my remark: “innodb-read through-only = 1” won't do the job for replication at all and breaks slave thread.
Following that, we have to include an replication consumer on the grasp server. The slave server will use this person to remotely log into grasp server and request binary logs. Log into MariaDB watch.
You have to get rid of the “automobile.cnf” from the datadir in the slave machine. The datadir could vary from every linux distro. To learn that out in mysql, operate: “Find @@DATADIR”.
