1、配置docker yum源
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
2、安裝Docker CE
yum install docker-ce
3、加入開機自啓
systemctl enable docker
4、啓動服務
systemctl start docker
5、配置鏡像加速器
vim /etc/docker/daemon.json
#寫入
{
"registry-mirrors": [
"https://dockerhub.azk8s.cn",
"https://reg-mirror.qiniu.com"
]
}
6、測試是否安裝成功
docker run hello-world
看到如下，說明安裝正確
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
1b930d010525: Pull complete
Digest: sha256:c3b4ada4687bbaa170745b3e4dd8ac3f194ca95b2d0518b417fb47e5879d9b5f
Status: Downloaded newer image for hello-world:latest
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.
(amd64)
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

7、重新加載服務配置和重啓服務
systemctl daemon-reload
systemctl restart docker
8、安裝docker-compose
curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version
