redhat下使用CentOS yum源,并安装docker

一、安装yum源

1.卸载yum

bash 复制代码
# 查看系统自身安装的yum软件包
rpm -qa | grep yum
# 卸载软yum件包
rpm -e 软件包名称 --nodeps  #可以使用简称如 rpm -e yum-* --nodeps

2. 安装yum

bash 复制代码
[root@bogon ~]# rpm -ivh --nodeps https://mirrors.aliyun.com/centos/8/BaseOS/x86_64/os/Packages/yum-4.2.23-4.el8.noarch.rpm 

3. 添加yum源

可以通过下载或文本编辑安装。

注意docker安装并未使用该yum源,因为报错了。不过添加后可以安装其他软件。

1).添加下载的方式添加

bash 复制代码
# 切换到yum源目录
/etc/yum.repos.d
# 下载或拷贝yum源文件
wget http://mirrors.aliyun.com/repo/Centos-8.repo?spm=a2c6h.25603864.0.0.3d975969k0L4KM

2).用文本编辑

bash 复制代码
# 编辑前如果文件已存在,则添加
vi /etc/yum.repos.d/Centos-8.repo
bash 复制代码
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
#

二、.安装docker

bash 复制代码
yum install -y docker

直接使用会报错:

containers-common-2:1-2.module_el8.5.0+890+6b136101.noarch conflicts with file from package redhat-release-8.5-0.8.el8

所以采用以下安装方式:

1.更新yum

bash 复制代码
yum update

2.卸载旧版本的docker

bash 复制代码
yum remove docker docker-common docker-selinux docker-engine

3. 安装依赖的软件包

bash 复制代码
yum install -y yum-utils device-mapper-persistent-data lvm2

4.设置yum 源

bash 复制代码
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

5. 不设定版本安装lasted Docker

bash 复制代码
yum install --allowerasing docker-ce docker-ce-cli containerd.io

6. 安装校验

bash 复制代码
systemctl start docker 
# 查看docker版本
 docker version
# 或
docker info
