需要centos7版本,内核版本不低于3.10
[root@localhost ~]# uname -r
3.10.0-514.el7.x86_64
第一步:更新当前软件:
[root@localhost ~]#yum update
第二步:添加Docker的yum源
[root@localhost ~]# cat /etc/yum.repos.d/docker.repo
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
第三步:安装Docker
[root@localhost ~]# yum install docker-engine
至此安装完成。
设置Docker服务开机自启
[root@localhost ~]# systemctl enable docker.service
启动Docker服务
[root@localhost ~]# systemctl start docker
验证Docker是否安装成功
[root@localhost ~]# docker run --rm hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID: https://cloud.docker.com/
For more examples and ideas, visit: https://docs.docker.com/engine/userguide/
由于国外的docker镜像仓库一般都比较慢,所以一般会使用国内的一些加速仓库,如阿里云
申请:https://cr.console.aliyun.com/#/accelerator
配置:
mkdir -p /etc/docker
cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://xxxxxxx.mirror.aliyuncs.com"]
}
https://xxxxxxx.mirror.aliyuncs.com替换成你申请到的地址。
sudo systemctl daemon-reload
sudo systemctl restart docker
