前言
本次内容基于在docker上添加dm数据库并运行，以及如何在docker中编辑dm数据库，并上传相应的软件包用来安装，以及配置相应的环境变量信息
一、docker安装和启动
1.docker安装
本次基于centos7来安装docker，docker的安装方法很多，这边我介绍下最为简单方便的安装方式
方法一：执行下面的命令，该命令为官方安装脚本，自动安装非常方便，大概需要等待5-10分钟安装会完毕
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
方法二：执行下面的命令，该命令为国内 daocloud 一键安装命令，跟上面的差不多也是自动安装，两条命令任选其一
curl -sSL https://get.daocloud.io/docker | sh
注意！运行上述安装命令请确保机器能够连接互联网
[root@czk ~]# curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
# Executing docker install script, commit: 614d05e0e669a0577500d055677bb6f71e822356

================================================================================
To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:
dockerd-rootless-setuptool.sh install
Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.
To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/
WARNING: Access to the remote API on a privileged Docker daemon is equivalent
to root access on the host. Refer to the 'Docker daemon attack surface'
documentation for details: https://docs.docker.com/go/attack-surface/
================================================================================2.docker启动
安装好的docker可以直接通过systemctl start docker来启动docker，启动后可以通过命令来查看是否启动成功
[root@czk ~]# systemctl status docker

docker restart dm8_01 重启重启
docker stop dm8_01 停止容器
三、docker安装dm数据库
在docker上安装dm数据库有两种方式，一种是下载达梦官网上docker镜像包，然后导入启动运行，另外一种是拉取仓库里的dm数据库，然后启动运行
方法一：基于达梦官网下载docker镜像包安装dm数据库
1.首先找到官网，然后点击下载 https://eco.dameng.com/download/
2.其次将下载好的dm8_docker.tar包上传到服务器上
3.然后新建一个/dm8目录，将包放到该目录下
4.进入dm8目录，运行docker import dm8_docker.tar dm8:v01 该命令用于导入包到docker中
[root@czk opt]# cd /dm8/
[root@czk dm8]# ll

[root@czk dm8]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
dm8 v01 ed4283b673ad 52 seconds ago 1.72GB6.然后启动dm数据库，启动命令如下：
两条命令都可以启动，任选其一
docker start dm8_01
docker run -itd -p 5236:5236 --name dm8_01 dm8:v01 /bin/bash /startDm.sh7.启动后查看下是否启动成功
[root@czk ~]# docker ps

[ OK ]方法二：基于仓库安装dm数据库
此方法比较简单，就是去搜索下dm数据库，然后拉取下来就行
1.先search搜寻下，找到其中的达梦数据镜像
[root@czk dm8]# docker images

注意，拉取的时候要附带下版本号也就是末尾的v1.0，如果不带上会报错

docker.io/zqingfa/dmserver:v1.03.启动dm数据库
docker run -d zqingfa/dmserver:v1.0
四、编辑dm文件以及配置rlwrap环境变量
1.首先编辑的话需要先进入到dm容器里面
docker exec -it dm8_01 /bin/bash
数据文件都在/dm8/data/PROD下面，直接vim就可以编辑
[root@czk ~]# docker exec -it dm8_01 /bin/bash
[root@9c656457d90e /]#

[root@9c656457d90e PROD]# pwd

[root@czk opt]# docker cp rlwrap-0.42-1.el6.x86_64.rpm dm8_01:/opt
[root@czk opt]# docker exec -it dm8_01 /bin/bash

注意解压的时候可能会提示你缺少perl依赖，记得用yum install装下perl相关的内容
