CentOS 安裝 Docker 報錯及解決過程
CentOS 安裝 Docker報錯資訊:
問題: package docker-ce-3:19.03.2-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed
- cannot install the best candidate for the job
- package containerd.io-1.2.2-3.3.el7.x86_64 is excluded
- package containerd.io-1.2.2-3.el7.x86_64 is excluded
- package containerd.io-1.2.4-3.1.el7.x86_64 is excluded
- package containerd.io-1.2.5-3.1.el7.x86_64 is excluded
- package containerd.io-1.2.6-3.3.el7.x86_64 is excluded
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
檢查發現containerd.io此軟體包已經安裝,但版本是1.2.0;所以造成這種安裝失敗的原因是containerd.io軟體包版本過低
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 //檢查相應的軟體包版本
[root@localhost ~]# yum -y install docker-ce-18.06.0.ce-3.el7 //安裝低版本的軟體包
2.安裝新版的containerd.io軟體包
containerd.io軟體包下載地址: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 //下載相關軟體包
[root@localhost ~]# yum -y install containerd.io-1.2.6-3.3.el7.x86_64.rpm //升級containerd.io軟體包
安裝完成後重新安裝Docker
[root@localhost ~]# yum -y install docker-ce //安裝Docker軟體包
安裝完成後啟動Docker
[root@localhost ~]# systemctl start docker //CentOS7啟動方法
[root@localhost ~]#server docker start //CentOS6啟動方法
檢視狀態後發現已經啟動成功
