部署最新版docker

1 关闭并禁用防火墙

# systemctl stop firewalld

#

# systemctl disable firewalld

2.停用并禁用selinux

# getenforce

Enforcing

# setenforce 0

# grep ^SELINUX= /etc/selinux/config

SELINUX=enforcing

# sed -ri s'#(SELINUX=)enforcing#\1disabled#' /etc/selinux/config

# grep ^SELINUX= /etc/selinux/config

SELINUX=disabled

3.卸载docker较旧的依赖项-如果当前服务器没有安装过docker环境，则可以跳过该步骤

yum -y remove docker docker-client docker-client-latest docker-common docker-lastest docker-lastest-logrotate docker-logrotate  docker-engine

4.切换国内的软件源

(1)备份CentOS官网的软件源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

(2)下载阿里云的软件源

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

(3)非阿里云ESC产品推荐操作该步骤

sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo

(4)生成本地缓存

yum makecache

5.配置docker-ce的软件源

yum -y install yum-utils

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

6 查看最新的docker版本

7 安装docker软件

[root@vm2_drserver yum.repos.d]# yum -y install docker-ce docker-ce-cli containerd.io

8 备份安装包：

[root@vm2_drserver ~]# mkdir docker_rpm_26

[root@vm2_drserver ~]# find /var/cache/yum/docker/ -type f -name "*.rpm" | xargs mv -t docker_rpm_26

[root@vm2_drserver ~]# ll

9 开启docker服务

10 配置docker守护进程-daemon.json

#cd /etc/docker/daemon.json

[root@vm2_drserver docker]# cat daemon.json

{

  "registry-mirrors": [

    "https://docker.hpcloud.cloud",

    "https://docker.m.daocloud.io",

    "https://docker.unsee.tech",

    "https://docker.1panel.live",

    "http://mirrors.ustc.edu.cn",

    "https://docker.chenby.cn",

    "http://mirror.azure.cn",

    "https://dockerpull.org",

    "https://dockerhub.icu",

    "https://hub.rat.dev",

    "https://proxy.1panel.live",

    "https://docker.1panel.top",

    "https://docker.m.daocloud.io",

    "https://docker.1ms.run",

    "https://docker.ketches.cn"]

}

[root@vm2_drserver docker]#

加载并重启docker

#systemctl daemon-reload

#systemctl restart docker

这个镜像源也很快：

[root@vm2_drserver docker]# cat daemon.json

{

  "dns": ["8.8.8.8", "114.114.114.114"],

  "registry-mirrors": [

    "https://docker.1ms.run",

    "https://docker.m.daocloud.io",

    "https://docker.1panel.live",

    "https://docker.mirrors.ustc.edu.cn"]

}
