在同一台服务器的2个实例（3355,3366）进行测试
1，设置主从裤
开通主库master（3355）的bin-log：
1)停止数据裤
2)修改3355数据库的my.cnf
增加bin-log字段及设置master的serverid
vim my.cnf
log-bin=/mysqldata/3355/mysql-bin
server-id=1
3)修改从库3366的server-id使其与主库区分
vim my.cnf
server-id=1
4）登录主库mysql查看是否设置成功
mysql> show variables like 'log_bin' \G
*************************** 1. row ***************************
Variable_name: log_bin
Value: ON
1 row in set (0.00 sec)
2，在主库master上创建从库slave同步权限的用户ddd
CREATE USER 'ddd'@'192.168.0.%' IDENDIFIED BY '123456';
grant replication slave on *.* TO 'ddd'@'192.168.0.%';
3，锁表（需要无业务进行时）
mysql> flush table with read lock;
4，查看master状态
mysql> show master status\G
*************************** 1. row ***************************
File: mysql-bin.000001
Position: 2400
Binlog_Do_DB:
Binlog_Ignore_DB:
Executed_Gtid_Set:
1 row in set (0.00 sec)
mysql> show master logs\G
*************************** 1. row ***************************
Log_name: mysql-bin.000001
File_size: 2400
1 row in set (0.00 sec)
5，新开窗口，备份主库数据
mysqldump -uroot -p123456 -S /mysqldata/3355/mysql.sock -NBAE --master-data=1 >/opt/rep.sql
6，将主库的只读锁去掉
mysql> unlock tables;
7，将主库数据导入从库slave
mysql -uroot -p123456 -S /mysqldata/3366/mysql.sock < /opt/rep.sql
8，在从库slave上设置MASTER文件
mysql -uroot -p123456 -S /mysqldata/3366/mysql.sock
mysql> CHANGE MASTER TO MASTER_HOST='192.168.0.68',MASTER_PORT=3355,MASTER_USER='ddd',MASTER_PASSWORD='123456',MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=2400;
9，在从库启动salve
mysql> start slave;
10，查看从库同步状态
mysql> show slave status\G
