Docker 离线版安装

首先、 下载 docker-20.10.9.tgz 和 docker-compose

https://download.csdn.net/download/cyw8998/88905939

一、离线安装docker
1.解压缩

docker-20.10.9.tgz

bash 复制代码

[root@centos247 docker]# tar -zxvf docker-20.10.9.tgz 
docker/
docker/containerd-shim-runc-v2
docker/dockerd
docker/docker-proxy
docker/ctr
docker/docker
docker/runc
docker/containerd-shim
docker/docker-init
docker/containerd

2. 解压的docker文件夹全部移至/usr/bin目录

bash 复制代码

cp -p docker/* /usr/bin

3. 将docker注册为系统服务

① 在/usr/lib/systemd/system/目录下，创建docker.service文件

② 编辑docker.service文件

bash 复制代码

vim /usr/lib/systemd/system/docker.service

bash 复制代码

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target docker.socket firewalld.service containerd.service time-set.target
Wants=network-online.target containerd.service

[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
ExecReload=/bin/kill -s HUP $MAINPID
TimeoutStartSec=0
RestartSec=2
Restart=always

# Note that StartLimit* options were moved from "Service" to "Unit" in systemd 229.
# Both the old, and new location are accepted by systemd 229 and up, so using the old location
# to make them work for either version of systemd.
StartLimitBurst=3

# Note that StartLimitInterval was renamed to StartLimitIntervalSec in systemd 230.
# Both the old, and new name are accepted by systemd 230 and up, so using the old name to make
# this option work for either version of systemd.
StartLimitInterval=60s

# 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

# Comment TasksMax if your systemd version does not support it.
# Only systemd 226 and above support this option.
TasksMax=infinity

# 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
OOMScoreAdjust=-500

[Install]
WantedBy=multi-user.target

4. 重启生效

bash 复制代码

重启守护进程
systemctl daemon-reload
systemctl start docker
查看docker状态
systemctl status docker
设置开机启动
systemctl enable docker

查看版本 docker version

二、离线安装docker-compose

1.安装

bash 复制代码

sudo mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

2.看版本查

docker-compose version
