Mysql主从环境概述

Mysql集群主从环境搭建

本次采用Docker部署集群,并且首先主从实例配置。
1.Mysql-Cluster集群服务规划

2.Mysql-Cluster集群先决条件

创建 Mysql-Cluster集群主要配置目录如下:
Mysql-Cluster集群

2.1 Mysql-Master节点[3308]

创建 Mysql-Slave节点主要配置文件目录以及配置文件如下:

5.Mysql-Cluster集群主从节点后续配置
5.1 Mysql-Cluster集群节点IP地址

1.mysql-master节点IPAddress: docker inspect --format='{{.NetworkSettings.IPAddress}}' mysql-master

Marklin:~ marklin$ docker inspect --format='{{.NetworkSettings.IPAddress}}' mysql-master 
172.17.0.13 
Marklin:~ marklin$

2.查看mysql-slave节点的IPAddress: docker inspect --format='{{.NetworkSettings.IPAddress}}' mysql-slave

Marklin:~ marklin$ docker inspect --format='{{.NetworkSettings.IPAddress}}' mysql-slave 
172.17.0.14 
Marklin:~ marklin$
5.2 Mysql-Cluster集群主从用户授权配置

进入Docker后台的两种方式:
1.通过终端输入docker ps查看容器进程,最后执行docker exec -it mysql容器名称/id bash
执行docker ps:

Marklin:~ marklin$ docker ps

进入mysql容器: docker exec -it d99ac84d4e11 bash

Marklin:~ marklin$ docker exec -it d99ac84d4e11 bash

2.通过Docker可视化后台进入:
点击Consle:

点击Conect:

进入到mysql容器:

登录mysql客户端:mysql -u root -p

root@mysql-master:/# mysql -u root -p 
Enter password:
