mysql server安装图解教程

mysql容器之间的replication配置实例详解

背景

上周公司培训了MySQL replication, 这个周末打算用所学来实践操作一下。

Master server:MySQL container mysql_master on NAS

Slave server: MySQK container mysql_slave on Mac mini

准备MySQL container

准备mysql_master

创建两个目录用来存放MySQL文件

  • ?
  • 1
  • 2
  • mkdir -p /mnt/md1/disk4/mysql
  • mkdir -p /mnt/md1/disk4/mysql-files
  • 创建用于测试的master mysql node

  • ?
  • 1
  • 2
  • [root@TNAS-2664 disk4]# docker run -d -p 3307:3306 -e MYSQL_ROOT_PASSWORD=123456 --name mysql_master -v /mnt/md1/disk4/mysql:/var/lib/mysql -v /mnt/md1/disk4/mysql-files:/var/lib/mysql-files mysql

  • 使用docker cp命令将my.cnf复制到host机器上进行更改

  • ?
  • 1
  • docker cp 40db0be51460:/etc/mysql/my.cnf .
  • 在my.cnf 加入以下配置

  • 将my.cnf 用docker cp 复制到mysql_master 容器中

  • ?
  • 1
  • docker cp my.cnf 40db0be51460:/etc/mysql/
  • 进入mysql_slave,发现my.cnf因为权限文件 is ignored,这将导致刚刚写入到my.cnf的配置无法生效

  • ?

  • 5
  • [root@TNAS-2664 ~]# docker exec -it mysql_master /bin/bash

  • mysql: [Warning] World-writable config file '/etc/mysql/my.cnf' is ignored.
  • mysql: [Warning] Using a password on the command line interface can be insecure.
  • Welcome to the MySQL monitor. Commands end with ; or \g.
  • 更改my.cnf的权限为664

  • ?
  • 1
  • 2
  • root@40db0be51460:/# chmod 644 /etc/mysql/my.cnf
  • root@40db0be51460:/# exit
  • 重启mysql_slave以使my.cnf生效

  • ?

    在Mac mini上创建两个目录用来存放MySQL文件

  • ?
  • 1
  • 2
  • mkdir -p /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql
  • mkdir -p /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql-files
  • 创建用于测试的mysql_slave container

  • ?
