I have setup Master-Master replication on two servers. Now, my question is that if I need to have the second master as only read-only, what should I do? I tried doing
mysql> flush tables with read lock;
Query OK, 0 rows affected (0.00 sec)
mysql> set global read_only=ON;
Query OK, 0 rows affected (0.00 sec)
But since this creates a read-lock in my 2nd master (Slave 1). The changes that I make in Master 1 is not propagated to Master 2 (Read-only).
What should I do such that - changes in Master 1 are getting updated to Master 2 but Master 2 should not be in write mode, Master-master(Active/Passive). Is it possible to do this?
