一、环境配置
- 操作系统:CentOS Linux release 8.4.2105
- Docker Version: 24.0.6
# 更新镜像源, Centos8 由yum 升级为dnf两个都可使用,yum源需可用
# 安装NTP
dnf install chrony# 修改chrony配置文件指定NTP源为阿里NTP
sed -r -i 's?^pool.+iburst?pool ntp.aliyun.com iburst?' /etc/chrony.conf
# 重启chrony服务
systemctl restart chronyd
# 开机自动启动chrony服务
systemctl enable chronyd
# 查看时间服务器状态
chronyc sources -v# 创建docker目录
mkdir -p /etc/docker /opt/docker
# 创建docker配置文件
tee /etc/docker/daemon.json <<-'EOF'
{"data-root": "/opt/docker","log-driver": "json-file","log-opts": {"max-size": "800m","max-file": "50"},"registry-mirrors": ["https://b9pmyelo.mirror.aliyuncs.com"]
}
EOF

二、安装Docker
# 安装镜像源配置工具
dnf install -y yum-utils
# 添加软件源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 安装docker
# 离线安装用户可以在这里执行dnf download --resolve docker-ce docker-ce-cli containerd.io下载所有包
dnf install docker-ce docker-ce-cli containerd.io
# 启动docker
systemctl start docker
# docker开机自动启动
systemctl enable docker
# containerd容器开机自动启动
systemctl enable containerd
# 查看docker版本信息
docker info
成功启动
三、错误解决
3.1 报错---yum 源配置
3.1.1 报错信息
执行 yum 安装报错如下:
Error: Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
原因:Centos8于2021年年底停止了服务,我们在使用yum源安装时候,出现下面错误“错误:Failed to download metadata for repo ‘AppStream’: Cannot prepare internal mirrorlist: No URLs in mirrorlist”。
3.1.2 解决
进入yum的repos目录
cd /etc/yum.repos.d/
修改所有的CentOS文件内容,最好是全部备份后再修改
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
yum 可以正常使用
3.2 报错---podman和buildah
3.2.1 报错信息
安装 docker 报错信息如下:
