mysql master slave setup

The data synchronization function of mysql not only provides load balancing for database queries to a certain extent, but also provides great help for database redundancy, backup, recovery, and load balancing. The data synchronization function can be implemented through master-slave replication, while master-

the 10.100.0.200 address, the password is 1234. (If the new old password algorithm for MySQL version is different, you can set: Set password for ' backup ' @ ' 10.100.0.200 ' =old_password (' 1234 '))2.2. Copy data(If you are completely new to installing MySQL master server, this step is not required.) Because the newly installed

Load balancing (read/write separation, improve data processing efficiency)2. High availability and failover capabilities (data distribution, stability improvement. Primary serv
