linux安装docker

国内不能连接到docker资源

Linux系统CentOS7.9

下载 docker

# VERSION_STRING=26.1.0
# wget https://download.docker.com/linux/static/stable/x86_64/docker-${VERSION_STRING}.tgz
# tar xf docker-${VERSION_STRING}.tgz

服务器链接不上资源  本地下载安装包  我使用的是  26.1.4  

https://download.docker.com/linux/static/stable/x86_64/

也可以从这里下载

https://download.csdn.net/download/sunsijia21983/89484849?spm=1001.2014.3001.5501

下载后，上传到服务器

复制可执行文件到指定目录

# cp docker/* /usr/bin/

ls -l /usr/bin/{containerd,containerd-shim-runc-v2,ctr,docker,dockerd,docker-init,docker-proxy,runc}

设置开机启动

# systemctl enable containerd.service docker.socket docker.service --now

Created symlink from /etc/systemd/system/multi-user.target.wants/containerd.service to /usr/lib/systemd/system/containerd.service.

创建文件

添加以上内容

/data/docker

建立这个文件夹

我这里配置的是/server/data/docker

 systemctl start docker

启动成功了

docker info

systemctl enable docker

设置开机自启

下载包

解压

复制

设置service

启动service

设置自启service

这是二进制包的安装方法
