(25年版)在CentOS 7.9 系统上构建docker
1. 查看系统当前内核信息,要求系统是64位,且内核版本为3.10版本
[root@localhost ~]# uname -r 3.10.0-1160.el7.x86_64
2.查看版本信息
[root@localhost ~]# cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"
3.暂时关闭防火墙
[root@localhost ~]# systemctl stop firewalld
4.永久关闭防火墙
[root@localhost ~]# systemctl disable firewalld Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
5.由于centos 7已经停更,因此需要移除原有的centsos.base基础镜像,再重新拉取
[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
6.重新下载Centos-Base基础镜像
[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo --2025-08-06 22:08:43-- http://mirrors.aliyun.com/repo/Centos-7.repo 正在解析主机 mirrors.aliyun.com (mirrors.aliyun.com)... 42.202.213.239, 117.66.50.79, 117.66.50.77, ... 正在连接 mirrors.aliyun.com (mirrors.aliyun.com)|42.202.213.239|:80... 已连接。 已发出 HTTP 请求,正在等待回应... 200 OK 长度:2523 (2.5K) [application/octet-stream] 正在保存至: “/etc/yum.repos.d/CentOS-Base.repo” 100%[============================================================================================>] 2,523 --.-K/s 用时 0s 2025-08-06 22:08:43 (492 MB/s) - 已保存 “/etc/yum.repos.d/CentOS-Base.repo” [2523/2523])

[root@localhost ~]# systemctl enable docker Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
15.查看docker版本
[root@localhost ~]# docker version Client: Docker Engine - Community Version: 26.1.4 API version: 1.45 Go version: go1.21.11 Git commit: 5650f9b Built: Wed Jun 5 11:32:04 2024 OS/Arch: linux/amd64 Context: default Server: Docker Engine - Community Engine: Version: 26.1.4 API version: 1.45 (minimum version 1.24) Go version: go1.21.11 Git commit: de5c9cf Built: Wed Jun 5 11:31:02 2024 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.6.33 GitCommit: d2d58213f83a351ca8f528a95fbd145f5654e957 runc: Version: 1.1.12 GitCommit: v1.1.12-0-g51d5e94 docker-init: Version: 0.19.0 GitCommit: de40ad0
16.华为镜像加速器的配置
先去注册华为云账号,然后获取自己的镜像加速器地址
注册的获取的步骤参考我的帖子链接:华为云镜像加速器配置 - 红酒人生 - 博客园
[root@localhost ~]# sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://每个人自己特有的地址.mirror.swr.myhuaweicloud.com"] } EOF
sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://每个人自己特有的华为云地址.mirror.swr.myhuaweicloud.com"] } EOF
获取自己的地址后做上面中文的替代,然后执行
17.加载配置文件
[root@localhost ~]# sudo systemctl daemon-reload
18.重启docker
[root@localhost ~]# systemctl restart docker
19.查看docker信息,确认是否已经确认配置好了华为镜像加速器
