文中有一處錯誤XSX本身發現的 master_port=3316 沒指定mysql

二、數據庫安裝

這裏貼一下Slave數據庫安裝的日誌數據庫

4.2 重啓從數據庫並設置Slave數據庫

net stop MySQL2
net start MySQL2

登陸從數據庫並作以下設置測試

mysql> stop slave;  #關閉Slave
mysql> change master to master_host='192.168.1.103',master_user='javen',master_password='123456',master_log_file='mysql-bin.000001', master_log_pos= 2519;

mysql> start slave;  #開啓Slave

注意：在這裏指定Master的信息，master_log_file是在配置Master的時候的File選項， master_log_pos是在配置Master的Position 選項，這裏要進行對應。this

4.3 查看Slave配置的信息

show slave status 查看配置的信息：spa

mysql> show slave status \G;
