centos7离线安装docker （二进制）

一、离线安装

新建路由

windos：route add 10.2.101.0 mask 255.255.255.0 160.5.1.254
ssh 10.2.101.19  rancher01-1

离线安装docker
https://download.docker.com/linux/static/stable/x86_64/  下载离线包地址

https://download.docker.com/linux/static/stable/aarch64/

https://docs.docker.com/engine/install/binaries/

1  setup    

cd /usr/local/resource/docker
tar -xvf docker-19.03.4.tgz 
mv docker/*  /usr/bin/ # 将二进制文件移动到bin下

 2  systemd docker.service

vim /etc/systemd/system/docker.service

3  然后将以下内容粘贴进去（通用）：

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
   
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
ExecReload=/bin/kill -s HUP $MAINPID
# Having non-zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container-local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
   
[Install]
WantedBy=multi-user.target

4  授予执行权限：    

chmod +x /etc/systemd/system/docker.service

5  重新加载：    

systemctl daemon-reload  
systemctl start docker    
systemctl enable docker.service  

6  测试是否成功：

systemctl status docker 
docker  -v 

rpm方式安装

rpm -ivh containerd.io-1.2.2-3.el7.x86_64.rpm
rpm -ivh container-selinux-2.107-3.el7.noarch.rpm
rpm -ivh docker-ce-18.09.8-3.el7.x86_64.rpm
rpm -ivh docker-ce-cli-18.09.8-3.el7.x86_64.rpm

7  配置docker 的阿里云加速器

容器镜像服务 (aliyun.com) 北京地区

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://q5bgvr7l.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

二、在线安装

1、查看安装过的docker：

yum list installed | grep docker
docker.x86_64                           2:1.13.1-74.git6e3bb8e.el7.centos
docker-client.x86_64                    2:1.13.1-74.git6e3bb8e.el7.centos
docker-common.x86_64                    2:1.13.1-74.git6e3bb8e.el7.centos

2、卸载docker

yum remove -y docker-ce.x86_64 docker-client.x86_64 docker-common.x86_64
yum remove docker \ 
docker-client \ 
docker-client-latest \ 
docker-common \ 
docker-latest \ 
docker-latest-logrotate \ 
docker-logrotate \ 
docker-selinux \ 
docker-engine-selinux \ 
docker-engine 

##慎重，会删除容器的数据
rm -rf /etc/systemd/system/docker.service.d rm -rf /var/lib/docker rm -rf /var/run/docker
rm -rf /var/lib/docker 

或者

yum -y remove docker-ce docker-common docker-selinux docker-engine

3、列出docker可用版本、搜索软件

yum list docker-ce --showduplicates | sort -r
yum search docker

4、添加源、指定版本安装

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/ 
yum install docker-ce-19.03.6 docker-ce-cli-19.03.6 -y

5、建立 Docker 用户组

groupadd docker
usermod -aG docker $USER
