16.1.2.3. Replication Slave Options and Variables
This section describes the server options and system variables that apply to slave replication servers.
You can specify the options either on the
set while the server is running by using the
variable values using SET.

Some slave server replication options are handled in a special way, in the sense that each is ignored

automatically when it starts. However, if you downgrade a newer server to a version older than 4.1.1,
you should manually remove the first line before starting the older server for the first time. Note that,
in this case, the downgraded server can no longer use an SSL connection to communicate with the
master.

with different values of the startup options that correspond to values in the
different values have no effect because the server continues to use the
different values, the preferred method is to use the
while the slave is running. Alternatively, you can stop the server, remove the
