docker容器主节点： 172.17.0.9
docker容器子节点： 172.17.0.10异步复制：
首先确认主库和从库是否一致，最好都是刚刚初始化的干净的数据库
如果主库正在使用不能初始化，就要先将主库的内容复制到从库上再做同步
1、先把master做一个备份，把备份出的文件传给slave
[root@99f856c64c02 /]# mysqldump -uroot -p -B test > test.dump
Enter password:
[root@72bd50b77c93 data]# mysql -uroot -p

5 rows in set (0.00 sec)
再到slave上将数据恢复
mysql> source /mysql/test3.sql
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test1 |
| test2 |
| test3 |
+--------------------+
6 rows in set (0.00 sec)
2.开启主节点Bin-log日志
vi /etc/my.cnf
添加bin-log配置
server-id=1
log-bin=mysql-bin
binlog_format=row
systemctl restart mysqld
3.创建复制用户，赋予用户权限
mysql> grant replication slave on *.* to ‘repl‘@‘%‘ identified by ‘mysql‘;
mysql> flush privileges;
mysql> show master status; 要记住position
+------------------+----------+--------------+--------------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+--------------------------+-------------------+
| mysql-bin.000003 | 683 | | mysql,information_schema | |
+------------------+----------+--------------+--------------------------+-------------------+
1 row in set (0.00 sec)
4.再到slave
mysql> change master to master_host=‘172.17.0.9‘,master_port=3306,master_user=‘repl‘,
-> master_password=‘mysql‘’,master_log_file=‘mysql-bin.000003‘,master_log_pos=683;
Query OK, 0 rows affected, 2 warnings (0.01 sec)
mysql> start slave;
Query OK, 0 rows affected (0.09 sec)
mysql> show slave status\G;

看到两个yes 就基本成功了 可以在主库上进行一些操作来测试一下
5.测试结果：
主库插入数据
