mysql同步一張表設定

1.主上修改my.cnf檔案：（主上）
server-id=1?
log-bin=mysql-bin


2.從上修改配置檔案 my.cnf（從上）
server-id=2
relay-log=replay-bin
read-only =1
replicate-ignore-db = mysql
replicate-ignore-db = test
replicate-ignore-db = information_schema
replicate-wild-do-table = gutest.a


3.建立 同步的使用者（主上）
GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* to rep@'192.168.1.196'  identified by 'rep';


4.在主要查詢主的日誌資訊（主上）
flush tables with read lock;
show master status;
unlock tables;


5.同步到主庫（從上）
stop slave;
reset slave;
CHANGE MASTER TO MASTER_HOST='192.168.1.195',MASTER_USER='rep',MASTER_PASSWORD='rep',MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=986;  #986是上一個語句查詢出來的日誌號
start slave;


6.在從上驗證：
mysql> show slave status\G
