Mysql replication official Chinese Document

Preparations for the mysql replication official Chinese documents: 1. Ensure that the mysql versions on the Master and Slave hosts are consistent to avoid unnecessary troubles. 2. Ensure that the Master/Slave can ping each other and communicate with each other.
