Docker 搭建开源 CMDB平台 “OpsManage” 之 Mariadb

整理了一下文档  今天来构建mariadb    

                                 

主机还是 centos  172.16.0.200 构建第二个images 

  直接shell.sh 完成

说明： 该脚本会在当前目录下检测是否有dockerfile 文件 没完创建  后又生成mariadb 配置文件 并开始 build 得mariadb  images  run 启

重点在start.sh 该脚本内   会copy（scripts 目录）进容器内为 容器启动时运行脚本  初始化 mariadb 并创建 SQL 库   ’opsmanage‘     ‘DBname’    ‘userName’   ’passwordName‘  可以在run容器时  用   -e  参数 传进 环境变量 进行修改

并可在宿主机  ll   /data/mysql   下查看到 容器是否   有创建opsmanage库    和有没有运行成功!     运行时所生成得   mysql.sock 

查看一下运行状态：

 

 

连续测试一下：
