Linux 离线安装docker

1、安装包的下载

　　进入 /opt 路径下下载安装包，并解压缩

cd /opt
sudo wget https://download.docker.com/linux/static/stable/x86_64/docker-20.10.9.tgz

2、解压安装包，并将解压后的文件夹内的东西全部放到 usr/local 下

sudo tar -xzvf docker-20.10.9.tgz
# 将解压后的文件夹 放到 usr/local 下
mv docker /usr/local/

3、将docker 文件夹下所有文件软连接到/usr/bin目录下，/user/bin是环境变量目录，在路径下都可以运行docker命令

cd /usr/local

ls -l docker

ln -s /usr/local/docker/containerd /usr/bin/containerd
ln -s /usr/local/docker/containerd-shim /usr/bin/containerd-shim
ln -s /usr/local/docker/containerd-shim-runc-v2 /usr/bin/containerd-shim-runc-v2
ln -s /usr/local/docker/ctr /usr/bin/ctr
ln -s /usr/local/docker/docker /usr/bin/docker
ln -s /usr/local/docker/dockerd /usr/bin/dockerd
ln -s /usr/local/docker/docker-init /usr/bin/docker-init
ln -s /usr/local/docker/docker-proxy /usr/bin/docker-proxy
ln -s /usr/local/docker/runc /usr/bin/runc


ln -s /usr/local/docker/containerd /usr/bin/containerd & ln -s /usr/local/docker/containerd-shim /usr/bin/containerd-shim & ln -s /usr/local/docker/containerd-shim-runc-v2 /usr/bin/containerd-shim-runc-v2 & ln -s /usr/local/docker/ctr /usr/bin/ctr & ln -s /usr/local/docker/docker /usr/bin/docker & ln -s /usr/local/docker/dockerd /usr/bin/dockerd & ln -s /usr/local/docker/docker-init /usr/bin/docker-init & ln -s /usr/local/docker/docker-proxy /usr/bin/docker-proxy & ln -s /usr/local/docker/runc /usr/bin/runc

4、创建编辑docker.service

vim /etc/systemd/system/docker.service

内容如下：

[Unit]

Description=Docker Application Container Engine

Documentation=https://docs.docker.com

After=network-online.target firewalld.service

Wants=network-online.target

[Service]

Type=notify

ExecStart=/usr/bin/dockerd

ExecReload=/bin/kill -s HUP $MAINPID

LimitNOFILE=infinity

LimitNPROC=infinity

TimeoutStartSec=0

Delegate=yes

KillMode=process

Restart=on-failure

StartLimitBurst=3

StartLimitInterval=60s

[Install]

WantedBy=multi-user.target

5、赋执行权限

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

systemctl daemon-reload

6、启动docker并设置开机自启

# docker 服务开机自启动命令 systemctl enable docker.service 

# 关闭docker 服务开机自启动命令 systemctl disable docker.service

7、 启动docker

systemctl start docker.service

8、 验证是否安装成功

[root@localhost docker]# sudo docker version

9、 docker的常用命令

查看docker状态：systemctl status docker
启动docker：systemctl start docker
停止docker：systemctl stop docker
拉取镜像：docker pull 名称
查看镜像：docker images
删除镜像：docker rmi 镜像id
查看正在启动的容器：docker ps
启动容器：docker start 容器名称
查看容器信息：docker inspect mongo
进入容器：docker exec -it 容器名称 /bin/bash
查看docker网络：docker network ls
当前使用docker镜像的容器（以monggodb为例）：docker container ls
查看所有容器：docker ps -a
当前正在使用的所有容器：docker container ls -all
停止容器：docker stop 名称
删除容器（容器需要停止运行再删除）：docker container rm 名称
删除所有容器：docker rm $(docker ps -a -q)
查看容器IP地址：docker inspect 321a999f2ecc | grep IPAddress
