使用docker-conpose部署master库：
version: "3"
services:
mysql5.7:
image: mysql:5.7
ports:
- 3307:3306
volumes:
- ./data:/var/lib/mysql
- ./conf:/etc/mysql/conf.d
- ./logs:/logs
restart: always
privileged: true
environment:
- TZ=Asia/Shanghai
- MYSQL_ROOT_PASSWORD=root
改配置：
[mysqld]
lower_case_table_names=1
skip-name-resolve
max_allowed_packet = 100M
## 同一局域网内注意要唯一
server-id=100
## 开启二进制日志功能，名称可以随便取（关键）
log-bin=mysql-bin
重启 docker-compose restart mysql5.7
进入容器命令行docker-compose exec mysql5.7 bash
连接mysql
root@c2c81ec6363a:/# mysql -hlocalhost -uroot -p
Enter password:
