CentOS?安裝 docker報錯信息：

? 檢查發現containerd.io此軟件包已經安裝，但版本是1.2.0；所以造成這種安裝失敗的原因是containerd.io軟件包版本過低
解決方法：
1.檢查Docker版本，安裝低版本，不進行安裝新版本Docker（在此就不繁瑣介紹低版本的安裝過程了）
[root@localhost?~]#?yum?list?docker-ce?--showduplicates?|?sort?-r //檢查相應的軟件包版本
?
? [root@localhost?~]#?yum?-y?install??docker-ce-18.06.0.ce-3.el7? //安裝低版本的軟件包?[object?Object]
? 2.安裝新版的containerd.io軟件包
containerd.io軟件包下載地址：https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm ?[root@localhost?~]#wget?https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm //下載相關軟件包
?[root@localhost?~]#?yum?-y?install?containerd.io-1.2.6-3.3.el7.x86_64.rpm //升級containerd.io軟件包
? 安裝完成后重新安裝Docker
?[root@localhost ~]# yum -y install docker-ce //安裝Docker軟件包
? 安裝完成后啟動Docker
[root@localhost?~]#?systemctl??start?docker //CentOS7啟動方法 [root@localhost?~]#server??docker?start //CentOS6啟動方法
? 查看狀態后發現已經啟動成功
