Redhat 7.4更新为Centos7的yum并安装docker-ce

以下命令请在root下执行
#删除原有的yum
rpm -qa|grep yum|xargs rpm -e --nodeps

#install centos yum
#wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-158.el7.centos.noarch.rpm
#wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
#wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-45.el7.noarch.rpm
#wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-45.el7.noarch.rpm
#wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-45.el7.noarch.rpm


###原来照上面的思路做　一直有问题，应该是没有安装python-iniparse包所致　随时间的变化　下面的链接可能会失效　需要到网站上确认小版本的变化
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-158.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-45.el7.noarch.rpm

#安装这些依赖
rpm -ivh yum-* --nodeps

#UPDATE YUM
yum clean all
yum makecache

#######DOWNLOAD ALL FILES
yum install docker-ce --downloadonly --downloaddir=/root/docker
#####以下是根据redhat7.4默认新装的情况做的处理，正确的做法　应该根据当前机器是否安装这个包，如果安装则更新，如果没有则安装的思路来做

redhat 需要注册后才能使用yum,所以有以上的操作。
