mysql讀寫分離筆記

主數據庫執行命令：

show master status;

獲得結果
mysql-bin.000009
2123

 

從數據庫執行命令

stop slave;

change master to
master_host='47.95.247.135',
master_port=3306,
master_user='root',
master_password='root',
master_log_file='mysql-bin.000009',
master_log_pos=4353;

start slave;

show slave status;

 

--回滾

set GLOBAL SQL_SLAVE_SKIP_COUNTER=1;

 

從數據庫更改，或者主數據庫刪除更改了從數據庫沒有的記錄，則會引發Slave_SQL_Running  爲：NO

重複執行以上操做，設置master_log_file和master_log_pos

 

 

主數據庫my.ini

server-id=1

 

log-bin=mysql-bin
#從庫會基於此log-bin來作複製，多個就在下面再寫一個
binlog-do-db=hsf
binlog-do-db=smarthome
#用於讀寫分離的具體數據庫，這裏我建立了mytest做測試
binlog_ignore_db=mysql
#不用於讀寫分離的具體數據庫
binlog_ignore_db=information_schema
#和binlog-do-db同樣，能夠設置多個

 

 

從數據庫my.ini

server-id=2

log-bin=mysql-bin
#從庫會基於此log-bin來作複製
replicate-do-db=hsf
replicate-do-db=smarthome
#用於讀寫分離的具體數據庫，這裏我建立了mytest做測試
