Centos 7.4 rpm 包安装 docker

安装包集合：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/

此次安装用到了列表中的：

containerd.io-1.2.5-3.1.el7.x86_64.rpm
docker-ce-cli-18.09.4-3.el7.x86_64.rpm
docker-ce-18.09.4-3.el7.x86_64.rpm

白天虚拟机上，竟然只安装 docker-ce-18.09.4-3.el7.x86_64.rpm 就可以了，结果晚上云服务器上陆续出现下面的问题

尝试直接安装 docker-ce-18.09.4-3.el7.x86_64.rpm

 [root@iZ286t0wuf9Z ftp_user]# yum install ./docker-ce-18.09.4-3.el7.x86_64.rpm

  You could try using --skip-broken to work around the problem

 [root@iZ286t0wuf9Z ftp_user]#

根据提示，“Requires: docker-ce-cli” 和 “Requires: containerd.io >= 1.2.2-3”，所以安装了前面提到的另外两个 rpm 文件。

 [root@iZ286t0wuf9Z ftp_user]# yum install containerd.io-1.2.5-3.1.el7.x86_64.rpm
 **************此处省略一大堆输出**************
 [root@iZ286t0wuf9Z ftp_user]# yum install docker-ce-cli-18.09.4-3.el7.x86_64.rpm
 **************此处省略一大堆输出**************
 [root@iZ286t0wuf9Z ftp_user]#

再尝试安装 docker-ce-18.09.4-3.el7.x86_64.rpm

 [root@iZ286t0wuf9Z ftp_user]# yum install ./docker-ce-18.09.4-3.el7.x86_64.rpm
 Loaded plugins: fastestmirror
 Examining ./docker-ce-18.09.4-3.el7.x86_64.rpm: 3:docker-ce-18.09.4-3.el7.x86_64

   libsepol-devel-2.5-10.el7.x86_64: [Errno 5] [Errno 12] Cannot allocate memory

根据提示 “because /usr/bin/applydeltarpm not installed”，所以如下操作

 [root@iZ286t0wuf9Z ftp_user]# yum provides '*/applydeltarpm'

原来是 deltarpm-3.6-3.el7.x86_64 的问题，所以继续操作

 [root@iZ286t0wuf9Z ftp_user]# yum install deltarpm

最后一次尝试安装 docker-ce-18.09.4-3.el7.x86_64.rpm

 [root@iZ286t0wuf9Z ftp_user]# yum install docker-ce-18.09.4-3.el7.x86_64.rpm
