Docker离线安装部署教程（以下以docker-26.0.0.tgz 为例进行离线安装）

1 docker下载

下载链接：https://download.docker.com/linux/static/stable/x86_64/

2 docker-compose下载

下载链接：https://github.com/docker/compose/releases/tag/v2.26.0

3 docker安装

1.使用mkdir -p /usr/local/docker/创建docker目录

2.使用工具Xftp将docker-26.0.0.tgz压缩包与docker-compose-linux-x86_64执行文件复制到docker目录下

3.解压docker-26.0.0.tgz压缩包并复制到/usr/bin/路径下

tar -zxvf docker-*.tgz

sudocp docker/* /usr/bin/

4.对docker-compose-linux-x86_64文件重命名并添加可执行权限

mv docker-compose-* docker-compose

chmod +x docker-compose

5.将docker-compose复制到/usr/bin并查看版本

sudocp docker-compose /usr/bin/

docker-compose version

6.创建docker.service文件

cd /etc/systemd/system/

touch docker.service

7.编辑docker.service文件，文件内容如下：

[Unit]

Description=Docker Application Container Engine

Documentation=https://docs.docker.com

After=network-online.target firewalld.service

Wants=network-online.target

[Service]

Type=notify

# 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

# 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

8.添加可执行权限并加载

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

sudo systemctl daemon-reload 

9.启动docker并查看状态

sudo systemctl start docker

sudo systemctl status docker

10.设置开机启动并查看版本

sudo systemctl enable docker.service

docker -v
