Linux 安装 与 Docker 安装 配置镜像

1.下载 Centos 镜像

Download - The CentOS Project

2.安装VM

 下17.5.2版本免费

https://knowledge.broadcom.com/external/article?articleNumber=368667 说明

NZ4RR-FTK5H-H81C1-Q30QH-1V2LA

许可证

 

 

 

 

 

 

 带界面的

 配置网络

 

先看网段 

点击虚拟网络编辑器 

先点击一下NAT模式的那个 看子网 192.168.181  所以我们的网段必须跟这个前三个一样

vm    .2默认是网关 所以最好我们选取的时候往后面排 

配置主机名 点击应用 

点击完成

 安装完成

3.安装Docker

1.先执行删除以前版本的Docker

  1. sudo yum remove docker \
  2.                   docker-client \
  3.                   docker-client-latest \
  4.                   docker-common \
  5.                   docker-latest \
  6.                   docker-latest-logrotate \
  7.                   docker-logrotate \
  8.                   docker-engine

2.安装yum存储库

yum -y install yum-utils device-mapper-persistent-data lvm2

这时候会出来一个镜像已经无法抵达的错误 

  1. Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
  2. 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"

3.解决错误 

我们的服务器没法访问镜像的网络，所以我们需要配置正确的镜像源；

进入 /etc/yum.repos.d文件目录；

cd /etc/yum.repos.d
1.先备份
sudo cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

编辑CentOS-Base.repo 文件（必选）

 全选替换 centos-base.repo

  1. # CentOS-Base.repo
  2. #
  3. # The mirror system uses the connecting IP address of the client and the
  4. # update status of each mirror to pick mirrors that are updated to and
  5. # geographically close to the client.  You should use this for CentOS updates
  6. # unless you are manually picking other mirrors.
  7. #
  8. # If the mirrorlist= does not work for you, as a fall back you can try the 
  9. # remarked out baseurl= line instead.
  10. #
  11. #
  12.  
  13. [base]
  14. name=CentOS-$releasever - Base
  15. baseurl=https://mirrors.aliyun.com/centos/$releasever/os/$basearch/
  16. gpgcheck=1
  17. gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
  18.  
  19. #released updates 
  20. [updates]
  21. name=CentOS-$releasever - Updates
  22. baseurl=https://mirrors.aliyun.com/centos/$releasever/updates/$basearch/
  23. gpgcheck=1
  24. gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
  25.  
  26. #additional packages that may be useful
  27. [extras]
  28. name=CentOS-$releasever - Extras
  29. baseurl=https://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
  30. gpgcheck=1
  31. gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
  32.  
  33. #contrib - packages by Centos Users
  34. [centosplus]
  35. name=CentOS-$releasever - Plus
  36. baseurl=https://mirrors.aliyun.com/centos/$releasever/centosplus/$basearch/
  37. gpgcheck=1
  38. enabled=0
  39. gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

 第一个就行  我用上面那个就好使

或者

  1. # CentOS-Base.repo
  2. #
  3. # The mirror system uses the connecting IP address of the client and the
  4. # update status of each mirror to pick mirrors that are updated to and

  60. gpgcheck=1
  61. enabled=0
  62. gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
2.编辑 CentOS-SCLo-scl-rh.repo 文件：(没有不用管)

替换内容： ***注意哦！！！***这里不是全部替换，只替换【centos-sclo-rh】下面的内容。

  1. [centos-sclo-rh]
  2. name=CentOS-$releasever - SCLo rh
  3. baseurl=https://mirrors.aliyun.com/centos/$releasever/sclo/$basearch/rh/
  4. gpgcheck=1
  5. enabled=1
  6. gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
3.编辑 CentOS-SCLo-scl.repo 文件（如果没有这个文件，不用管）
  1. [centos-sclo-sclo]
  2. name=CentOS-$releasever - SCLo sclo
  3. baseurl=https://mirrors.aliyun.com/centos/$releasever/sclo/$basearch/sclo/
  4. gpgcheck=1
  5. enabled=1
  6. gpgkey=https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
4.清理缓存、重新加载缓存
清理缓存 
yum clean all
加载缓存 
yum makecache

完美解决

此方法引入 感谢博主

【CentOS7】yum 报错：Could not retrieve mirrorlist http://mirrorlist.centos.org_loading mirror speeds from cached hostfile could n-CSDN博客

4.配置镜像源 

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

 5.安装最新版本

sudo yum install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

如果想安装具体版本

  1. dnf list docker-ce --showduplicates | sort -r
  2.  
  3. docker-ce.x86_64    3:27.4.0-1.el9    docker-ce-stable
  4. docker-ce.x86_64    3:27.3.1-1.el9    docker-ce-stable
  5. <...>
sudo yum install docker-ce- docker-ce-cli- containerd.io docker-buildx-plugin docker-compose-plugin

6.启动docker

sudo systemctl enable --now docker

7.拉取Hello world 镜像 并运行

sudo docker run hello-world
1.出现报错
  1. Unable to find image 'hello-world:latest' locally
  2. docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded.
  3. See 'docker run --help'.
2.配置阿里云镜像

sudo mkdir -p /etc/docker
  1. sudo tee /etc/docker/daemon.json <<-'EOF'
  2. {
  3.   "registry-mirrors": ["https://udron5t9.mirror.aliyuncs.com"]
  4. }
  5. EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
3.最后把镜像在做上补充
vim /etc/docker/daemon.json
  1. {
  2.   "registry-mirrors": [
  3.     "https://docker.registry.cyou",
  4.     "https://docker-cf.registry.cyou",
  5.     "https://dockercf.jsdelivr.fyi",
  6.     "https://docker.jsdelivr.fyi",
  7.     "https://dockertest.jsdelivr.fyi",
  8.     "https://mirror.aliyuncs.com",
  9.     "https://dockerproxy.com",
  10.     "https://mirror.baidubce.com",
  11.     "https://docker.m.daocloud.io",
  12.     "https://docker.nju.edu.cn",
  13.     "https://docker.mirrors.sjtug.sjtu.edu.cn",
  14.     "https://docker.mirrors.ustc.edu.cn",
  15.     "https://mirror.iscas.ac.cn",
  16.     "https://docker.rainbond.cc",
  17.     "https://udron5t9.mirror.aliyuncs.com"
  18.   ]
  19. }
  1. systemctl daemon-reload
  2. systemctl restart docker

再次保存重启

4.运行 Hello world

完美解决 

这样docker就安装完毕了
