docker的安装

Posted 2021-08-09 y_zilong

1、docker ubuntu安装

#如果你过去安装过docker，先删除
yzil@ubuntu01:~$ sudo apt-get remove docker docker-engine docker.io

#首次安装依赖
yzil@ubuntu01:~$ sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common

#信任docker的GPG公钥
yzil@ubuntu01:~$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

#1、对于amd64架构的计算机，添加软件仓库
yzil@ubuntu01:~$ sudo add-apt-repository \\
>    "deb [arch=amd64] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \\
>    $(lsb_release -cs) \\
>    stable"

#2、如果你是树莓派或其它ARM架构计算机，请运行:
echo "deb [arch=armhf] https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/ubuntu \\
     $(lsb_release -cs) stable" | \\
    sudo tee /etc/apt/sources.list.d/docker.list
    
#最后安装
yzil@ubuntu01:~$ sudo apt-get update
yzil@ubuntu01:~$ sudo apt-get install docker-ce

2、docker centos 7的安装

#docker所有的操作都必须要使用root来完成！
#如果你之前安装过 docker，请先删掉
[root@cent7-1 ~]# yum remove docker docker-common docker-selinux docker-engine

#安装一些依赖
[root@cent7-1 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2

#根据你的发行版下载repo文件:
[root@cent7-1 ~]# wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo

#把软件仓库地址替换为 TUNA
[root@cent7-1 ~]# sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo

#最后安装
#安装指定的docker-ce版本

[root@cent7-1 ~]# yum list docker-ce.x86_64 --showduplicates | sort -r

[root@cent7-1 ~]# yum -y install docker-ce-19.03.9-3.el7

[root@cent7-1 ~]# systemctl enable --now docker

3、docker centos 7一键脚本的安装

[root@cent7_6 ~]# cat install_docker_for_centos7.sh 
#!/bin/bash
COLOR="echo -e \\\\033[1;31m"
END="\\033[m"
VERSION="19.03.9-3.el7"
wget -P /etc/yum.repos.d/  https://download.docker.com/linux/centos/docker-ce.repo || { ${COLOR}"互联网连接失败，请检查网络配置！"${END};exit;}
sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
yum clean all
yum -y install docker-ce-$VERSION || { ${COLOR} " yum源配置失败，请检查yum源配置 "${END};exit;}
mkdir -p /etc/docker
