# 使用 Docker 建立 Mysql 集群 ## 软件环境介绍 操作系统：Ubuntu server 64bit 14.04.1 Docker 版本 1.6.2 数据库：Mariadb 10.10 （Mariadb 是 MySQL 之父在 MySQL 被 Oracle 收购之后创建的分支，性能上优于 MySQL 开源版本） ## 第一步 安装 Docker 对于 Ubuntu，建议直接联网安装 1，-name〈给容器取个好记的名称〉 2, -e MYSQL_ROOT_PASSWORD = '给数据库一个 root 用户密码' 3，-p<映射到本机的端口>:3306 4，-v〈本机的数据库存放目录〉:/var/lib/mysql 5，设定 MYSQL_USER、MYSQL_PASSWORD、MYSQL_DATABASE 环境变量可以使容器在运行时同时创建你 环境变量可以使容器在运行时同时创建你所需要的数据库和带有全部权限的用户及其对应密码 6，设定 TERM 环境变量的值可以解决容器不能进入 mysql 控制台的问题。 对于不是自己建立的镜像，建立出来的容器未必能一次达到要求，建议是将 run 命令写成脚本，创建后使用 docker inspect <容器名> 仔细查看容器信息，关注镜像公开的端口和文件目录。如果发现达不到要求，使用 docker rm -f <容器名>
