Linux安装docker
Red Hat安装docker
- 清理已经安装的docker
sudo yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine \podman \runc
- 对于Red Hat记得要移除旧的podman、runc，如果不移除可能后面安装docker时会有版本冲突
- 安装必要工具
yum install -y yum-utils
- 添加下载源
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
- 不要用官网给的RHEL给的下载源https://download.docker.com/linux/rhel/docker-ce.repo
- 查看可用版本列表
yum list docker-ce --showduplicates | sort -r
yum list docker-ce-cli --showduplicates | sort -r
- 安装需要版本docker及docker-compose
yum install docker-ce-20.10.14 docker-ce-cli-20.10.14 containerd.io docker-compose-plugin
- 确认安装版本及是否成功安装
docker versiondocker compose version
- 启动docker
systemctl start docker

修改存储目录
- 停用docker
systemctl stop docker
- 创建存储目录
mkdir -p /user01/data/docker
- 修改daemon.json文件,如果没有则新建
mkdir -p /etc/dockercat > /etc/docker/daemon.json <<EOF
{"exec-opts": ["native.cgroupdriver=systemd"],"log-driver": "json-file","log-opts": {"max-size": "100m"},"storage-driver": "overlay2","storage-opts": ["overlay2.override_kernel_check=true"],"registry-mirrors": ["https://uyah70su.mirror.aliyuncs.com"],"data-root": "/user01/data/docker"
}
EOF
- 重启docker使配置生效
systemctl daemon-reloadsystemctl restart docker## 配置开机重启
systemctl enable docker
- 确认修改是否生效
