一.Docker镜像的制作

1.1 在linux虚拟机中安装docker

[root@localhost ~]# uname -r
3.10.0-862.el7.x86_64
[root@localhost ~]# yum install docker

1.2 上传xfce-tools-base.tar文件到虚拟机

这里将基础镜像上传到/root/vm-docker-kecheng

1.3 下载vnc-viewer客户端软件

下载vnc-viewer客户端软件（该软件用于连接docker桌面）:

下载地址为：https://www.realvnc.com/en/connect/download/viewer/

1.4 在xfce-tools-base所在目录执行命令

在xfce-tools-base.tar文件所在目录执行命令，这里放在了：/root/vm-docker-kecheng

[root@localhost vm-docker-kecheng]# ls
xfce-tools-base.tar
[root@localhost vm-docker-kecheng]# pwd
/root/vm-docker-kecheng
[root@localhost vm-docker-kecheng]# docker load -i xfce-tools-base.tar

1.5 启动镜像

[root@localhost vm-docker-kecheng]# docker run -d -p 5904:5901 xfce-tools-base  run.sh
b3ad03aefa8769157fd2f26aa761ba5bf60989b2a4d054381988a3dffcbbca50

1.6 查看镜像

[root@localhost vm-docker-kecheng]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                    NAMES
b3ad03aefa87        xfce-tools-base     "run.sh"            6 seconds ago       Up 5 seconds        0.0.0.0:5904->5901/tcp   jolly_hawking
bb9e19cbfd14        xfce-tools-base     "run.sh"            4 days ago          Up About an hour    0.0.0.0:5901->5901/tcp   silly_kalam
[root@localhost vm-docker-kecheng]#

1.7 使用vnc-viewer可视化软件连接

1.打开vnc-viewer,输入server地址,格式是 IP:5904

2.输入密码 vncpassword,点击OK

3.基础镜像中已安装JDK8，FireFox，IDEA，DBeaver（可右键-设置中修改屏幕分辨率）默认用户是bonc,可通过sudo su 切换到root账户。

1.8 上传软件包

1.在容器中新建一个存储软件包的目录：这里是/home/bonc/bigdata-software

[bonc@b3ad03aefa87 ~]$ mkdir -p bigdata-software
[bonc@b3ad03aefa87 ~]$ ls
bigdata-software  Desktop  \u6a21\u677f
[bonc@b3ad03aefa87 ~]$ pwd
/home/bonc
[bonc@b3ad03aefa87 ~]$ cd bigdata-software/
[bonc@b3ad03aefa87 bigdata-software]$ ls
[bonc@b3ad03aefa87 bigdata-software]$ pwd
/home/bonc/bigdata-software
[bonc@b3ad03aefa87 bigdata-software]$

2.在宿主机中上传软件包到这个容器/home/bonc/bigdata-software的目录下

1.9 上传软件包

在容器b3ad03aefa87中查看：

1.10 使用commit制作镜像

1.11 导出镜像

二.配置docker节点基础环境

我们使用docker命令来创建三个服务器节点，然后将需要的软件包上传到指定的目录下，以备后续安装搭建集群使用。

2.1 创建节点

2.2 查看节点

2.3 使用vnc-viewer客户端软件连接各个节点

#节点1

[bonc@f62ceec424b5~]$ mkdir -p  bigdata-software
[bonc@f62ceec424b5~]$ ls
Desktop  bigdata-software  \u6a21\u677f
[bonc@72be4473c97f ~]$

#节点2

[bonc@72be4473c97f ~]$ mkdir -p bigdata-software
[bonc@72be4473c97f~]$ ls
Desktop   bigdata-software  \u6a21\u677f
[bonc@72be4473c97f ~]$

#节点3

[bonc@1d1bb7519d04 ~]$ mkdir -p  bigdata-software
[bonc@1d1bb7519d04~]$ ls
Desktop  bigdata-software  \u6a21\u677f
[bonc@72be4473c97f ~]$

2.4 上传软件包到每个节点

#上传到节点1

[root@localhost kecheng-software-packages]# docker cp apache-flume-1.9.0-bin.tar.gz f62ceec424b5:/home/bonc/bigdata-software
[root@localhost kecheng-software-packages]# docker cp kafka_2.12-2.1.0.tgz  f62ceec424b5:/home/bonc/bigdata-software
[root@localhost kecheng-software-packages]# docker cp zookeeper-3.4.10.tar.gz  f62ceec424b5:/home/bonc/bigdata-software

#上传节点2

[root@localhost kecheng-software-packages]# docker cp apache-flume-1.9.0-bin.tar.gz 72be4473c97f:/home/bonc/bigdata-software
[root@localhost kecheng-software-packages]# docker cp kafka_2.12-2.1.0.tgz  72be4473c97f:/home/bonc/bigdata-software
[root@localhost kecheng-software-packages]# docker cp zookeeper-3.4.10.tar.gz  72be4473c97f:/home/bonc/bigdata-software
