环境搭建及MySQL安装步骤省略，根据已有的镜像创建容器
master数据库
docker run -it -d --privileged=true --name master -p 33060:3306 -p 220:22 -p 8080:80 -p 1024:1024 -p 16379:6379 -p 9001:9001 -v E:\www\:/home/www ssh_network_vim_lnmp_redis_swoole_supervisor /usr/sbin/init
slave1数据库
docker run -it -d --privileged=true --name slave1 -p 33061:3306 -p 221:22 -p 8081:80 -p 2024:1024 -p 26379:6379 -p 9002:9001 -v E:\www\:/home/www ssh_network_vim_lnmp_redis_swoole_supervisor /usr/sbin/init
slave2数据库
docker run -it -d --privileged=true --name slave2 -p 33062:3306 -p 222:22 -p 8082:80 -p 3024:1024 -p 36379:6379 -p 9003:9001 -v E:\www\:/home/www ssh_network_vim_lnmp_redis_swoole_supervisor /usr/sbin/init

如果是项目中途使用主从复制，可以使用下面方法迁移数据
锁定所有表
1
2
| mysql> FLUSH TABLES WITH READ LOCK;
Query OK, 0 rows affected (2.59 sec)
|
备份表
1
| [root@b04f945297ac ~]# mysqldump -uroot -p123456 --all-databases -l -F >/tmp/all_db.sql
|
解锁
1
2
| mysql> UNLOCK TABLES;
Query OK, 0 rows affected (0.00 sec)
|
传输数据到从库
1
| scp -P 221/222 /tmp/all_db.sql root@192.168.2.107:/tmp
|
slave数据库
修改server-uuid
将/var/lib/mysql/auto.conf

| [auto]
server-uuid=f781e2b4-28e1-11e8-a1c0-0242ac110001

| log-bin=mysql-bin #启动二进制文件
server_id=101 #服务器ID

重启MySQL；
导入主备份文件
1
| [root@9ae039d46474 tmp]# mysql -uroot -p123456 < /tmp/all_db.sql
