一.安装CentOS7.6操作系统

　　该过程过于简单,且CentOS 7各个版本之间部署方式几乎雷同，可参考我之前的笔记:"https://www.cnblogs.com/yinzhengjie/p/10181840.html"

　　生产环境如果你要安装docker的话建议使用CentOS7.2以上版本,如果使用的版本较低可能会出现docker无法启动的情况。

 

二.安装pouch容器管理工具

1>.查看操作环境

[[email protected] ~]# cat /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core) 
[[email protected] ~]# 
[[email protected] ~]# uname -r
3.10.0-957.el7.x86_64
[[email protected] ~]# 
[[email protected] ~]# uname -m
x86_64
[[email protected] ~]# 

2>.下载阿里的软件源

[[email protected] ~]# wget http://mirrors.aliyun.com/opsx/pouch/centos7.repo -O /etc/yum.repos.d/pouch-centos7.repo
