mysql 主从
建同步用戶
CREATE USER 'repl'@'%' IDENTIFIED BY 'repl123';
GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%';
*************主
[mysqld]
log-bin=mysql-bin
server-id=1
binlog-do-db=facebk #數據庫
systemctl restart mysql
show master status;
*************從
[mysqld]
server-id=2
replicate-do-db = facebk
replicate-ignore-db = mysql #忽略的庫
systemctl restart mysql
mysql> stop slave;
mysql> CHANGE MASTER TO
-> MASTER_HOST='192.168.1.233',
-> MASTER_USER='repl',
-> MASTER_PASSWORD='repl123',
-> MASTER_LOG_FILE='mysql-bin.000002',
-> MASTER_LOG_POS=313;
mysql> start slave;
show slave status \G;

而最新版5.7版本中，如下三步就可以不用重啟服務器就生效了：
STOP SLAVE SQL_THREAD;
CHANGE REPLICATION FILTER REPLICATE_IGNORE_DB=(demo);
START SLAVE SQL_THREAD;
?
路徑
?show?variables?like?'log_%';?

mysql從庫Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'報錯處理
- 從：
show slave status
Slave_IO_Running: 狀態變成NO了
stop slave;
?
- 主：
flush logs;
?
刷新后的日志會+1
例如上面的?File: mysql-bin.000113 會變成?File: mysql-bin.000114
show master status
?
- 從：
CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000114',MASTER_LOG_POS=120;
start slave
show slave status
?
解決。。。
