修改master基本配置
vim /mydata/mysql/master/conf/my.cnf

[client]
default-character-set=utf8
 
[mysql]
default-character-set=utf8
 
[mysqld]
init_connect=‘SET collation_connection = utf8_unicode_ci‘
init_connect=‘SET NAMES utf8‘
character-set-server=utf8
collation-server=utf8_unicode_ci

skip-character-set-client-handshake
skip-name-resolve 
#跳过域名解析
注意：skip-name-resolve一定要加，不然连接mysql会超级慢

添加master主从复制部分配置
server_id=1
log-bin=mysql-bin
read-only=0
binlog-do-db=gmall_ums
binlog-do-db=gmall_pms
binlog-do-db=gmall_oms
binlog-do-db=gmall_sms
binlog-do-db=gmall_cms

replicate-ignore-db=mysql #忽略的数据库
replicate-ignore-db=sys
replicate-ignore-db=information_schema
replicate-ignore-db=performance_schema

1、进入master容器
docker exec -it mysql /bin/bash

2、进入mysql内部 （mysql –uroot -p）

   1）、授权root可以远程访问（ 主从无关，为了方便我们远程连接mysql）
　　　　grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘ with grant option;
　　　　flush privileges;
   2）、添加用来同步的用户
       GRANT REPLICATION SLAVE ON *.* to ‘backup‘@‘%‘ identified by ‘123456‘;
3、查看master状态
   show master status\G;

1、进入slaver容器
docker exec -it mysql-slaver-01 /bin/bash
2、进入mysql内部（mysql –uroot -p）
   1）、授权root可以远程访问（ 主从无关，为了方便我们远程连接mysql）
　　　  grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘ with grant option;
　　　  flush privileges;
   2）、设置主库连接
　　　　change master to master_host=‘192.168.159.128‘,master_user=‘backup‘,master_password=‘123456‘,master_log_file=‘mysql-bin.000001‘,master_log_pos=0,master_port=3307;
  3）、启动从库同步
　　　　start slave;
  4）、查看从库状态
     　show slave status\G;
