#(0)环境规划
mysql版本:5.6
master01 : 192.168.19.131
master02 : 192.168.19.132
#(1)安装docker和docker-compose
curl -o /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install docker-ce-17.06.0.ce-1.el7.centos.x86_64 -y
systemctl enable docker
systemctl start docker
cat > /etc/docker/daemon.json < /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
#(2)准备目录
mkdir /mysql3307/{data,conf} -pv
mkdir /temp/docker/compose/ -pv
#(3)master01 和 master02 的配置文件
注意修改server-id和 auto_increment_offset

#(4)compose文件
#cat /temp/docker/mysql3307/mysql3307.yaml
version: '2.2'
services:
mysql3307:
hostname: mysql3307
container_name: mysql3307
restart: always
image: registry.cn-hangzhou.aliyuncs.com/wangfang-dev/mysql:5.6
ports:
- 3307:3306
volumes:
- /mysql3307/conf:/etc/mysql/conf.d
- /mysql3307/data:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: 123456
cpus: 1
mem_limit: 2048m
#(5)启动容器
docker-compose -f /temp/docker/mysql3307/mysql3307.yaml up -d
两台容器正常启动成功
#(6)在master01上配置复制权限
docker exec -it mysql3307 bash
mysql -uroot -p123456
grant replication slave,replication client on *.* to 'rep'@'%' identified by 'rep';
#(7)在master02发起连接以及验证
docker exec -it mysql3307 bash
mysql -uroot -p123456
change master to master_host='192.168.19.131',master_user='rep',master_password='rep',master_port=3307,master_auto_position=1;
start slave;
show slave status\G
#(8)在master01上发起连接以及验证
docker exec -it mysql3307 bash
mysql -uroot -p123456
change master to master_host='192.168.19.132',master_user='rep',master_password='rep',master_port=3307,master_auto_position=1;
start slave;
#(9)分别在master01和master02 进行dml, dcl语句验证
master01上
master02上
master01上
master02上
