shell脚本搭建容器云完结篇(三)

经过不断的调试与漫长的等待，终于完成了shell脚本容器云的安装，非常感谢王师兄的指导！

总结一下今天的学习过程

1，简化hostname与IP-hostname映射配置，去除前天使用的 ansible-playbook changehostname.yml 方式

2，重新创建基础镜像：yum源更新，关闭防火墙，关闭SELINIX，设置开机时间等待1秒，桥接模式    

      安装deltarpm并执行yum provides '*/applydeltarpm'，也是一个软件，不知道是干啥的，只知道是解决这个问题的

     Error: Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

       yum install -y deltarpm

       yum provides '*/applydeltarpm'

3，利用重新构建的基础镜像创建3个新的虚拟机，利用写的js文件和shell脚本一体化搭建容器云（自己认为的一体化，见笑了）

       js文件

5，自己又梳理了一下shell安装的步骤，是自身更加理解了安装过程，不过各个组件的理解以及相互的通信原理还是不太明白

6，晚上着手准备了在docker中的hadoop集群安装的shell脚本，未成形，希望明天能完成

      有些啰嗦，希望csdn不会怪我把它当成了日记本，哈哈，明天加油！
