根據官方文檔：https://docs.docker.com/install/linux/docker-ce/centos/搭建docker
1.卸載docker舊版本：
sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine\
2.安裝相關工具類：
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
3.配置docker倉庫：
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
會報以下錯誤：
Loaded plugins: fastestmirror
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
Could not fetch/save url https://download.docker.com/linux/centos/docker-ce.repo to file /etc/yum.repos.d/docker-ce.repo
: [Errno 14] curl#35 - "TCP connection reset by peer
這是由於國內訪問不到docker官方鏡像的緣故
可以通過aliyun的源來完成：
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
出現以下內容則表示docker倉庫配置成功：
Loaded plugins: fastestmirror
adding repo from: http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
grabbing file http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo4.安裝docker
sudo yum install docker-ce
出現以下異常：
Loaded plugins: fastestmirror
base
https://download-stage.docker.com/linux/centos/7/x86_64/stable/repodata/repomd.xml: [Errno 14] curl#35 - "TCP connection reset by peer"
Trying other mirror.
One of the configured repositories failed (Docker CE Stable - x86_64),
and yum doesn‘t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=docker-ce-stable ...
4. Disable the repository permanently, so yum won‘t use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable docker-ce-stable
or
subscription-manager repos --disable=docker-ce-stable
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=docker-ce-stable.skip_if_unavailable=true
failure: repodata/repomd.xml from docker-ce-stable: [Errno 256] No more mirrors to try.
https://download-stage.docker.com/linux/centos/7/x86_64/stable/repodata/repomd.xml: [Errno 14] curl#35 - "TCP connection reset by peer"
分析原因為：阿裏的鏡像庫文件也指向docker官方庫，所以需要修改庫文件
sudo vim /etc/yum.repos.d/docker-ce.repo
通過命令把https://download-stage.docker.com替換為http://mirrors.aliyun.com/docker-ce
命令如下：:%s#https://download-stage.docker.com#http://mirrors.aliyun.com/docker-ce#g
在執行安裝docker的部分媽可安裝成功。
sudo yum install docker-ce
內容如下：
Installed:
docker-ce.x86_64 0:18.03.0.ce-1.el7.centos
Dependency Installed:
audit-libs-python.x86_64 0:2.7.6-3.el7 checkpolicy.x86_64 0:2.5-4.el7 container-selinux.noarch 2:2.42-1.gitad8f0f7.el7 libcgroup.x86_64 0
libtool-ltdl.x86_64 0:2.4.2-22.el7_3 pigz.x86_64 0:2.3.3-1.el7.centos policycoreutils-python.x86_64 0:2.5-17.1.el7 python-IPy.noarch
Complete!
5.驗證docker安裝成功：
啟動docker：sudo systemctl start docker
驗證docker:
sudo docker run hello-world
則會出現以下異常：
Unable to find image ‘hello-world:latest‘ locally
latest: Pulling from library/hello-world
9bb5a5d4561a: Pulling fs layer
docker: error pulling image configuration: Get https://dseasb33srnrn.cloudfront.net/registry-v2/docker/registry/v2/blobs/sha256/e3/e38bc07ac18e
See ‘docker run --help‘.
此錯誤也是網絡問題：國內無法訪問dockerhub
配置阿裏雲的docker鏡像庫：在阿裏雲開通容器鏡像服務拿到加速地址在執行以下命令：
sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-‘EOF‘ { "registry-mirrors": ["https://｛自已的編碼｝.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker
再次驗證docker:
sudo docker run hello-world
出現以下內容則表示安裝成功：
Unable to find image ‘hello-world:latest‘ locally
latest: Pulling from library/hello-world
9bb5a5d4561a: Pull complete
Digest: sha256:f5233545e43561214ca4891fd1157e1c3c563316ed8e237750d59bde73361e77
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
