CentOS7 离线部署docker和docker-compose环境

一、Docker 离线安装

下载docker tar.gz包

下载地址： Index of linux/static/stable/x86_64/

本文选择版本：23.0.6

2.创建docker.service文件

vi docker.service文件内容如下：

[Unit]
Description=Docker Application Container Engine
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
LimitCORE=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s

[Install]
WantedBy=multi-user.target

一键安装脚本

注意：安装脚本和docker.service文件放在安装包的同级目录下

vi install_docker.sh

#!/bin/sh
echo '解压tar包...'
tar_file=$1
if [ -f $tar_file ];then
  tar -zxvf $tar_file

  echo '将docker目录移到/usr/bin目录下...'
  cp docker/* /usr/bin/

  echo '将docker.service 移到/etc/systemd/system/ 目录...'
  cp docker.service /etc/systemd/system/

  echo '添加文件权限...'
  chmod +x /etc/systemd/system/docker.service

  echo '重新加载配置文件...'
  systemctl daemon-reload

  echo '启动docker...'
  systemctl start docker

  echo '设置开机自启...'
  systemctl enable docker.service

  echo 'docker安装成功...'
  docker -v
else
  echo "$tar_file,文件不存在"
fi

执行脚本

chmod +x install_docker.sh

./install_docker.sh tar包路径

解压tar包...

docker/

docker/docker-proxy

docker/containerd-shim-runc-v2

docker/ctr

docker/docker

docker/docker-init

docker/runc

docker/dockerd

docker/containerd

将docker目录移到/usr/bin目录下...

将docker.service 移到/etc/systemd/system/ 目录...

添加文件权限...

重新加载配置文件...

启动docker...

设置开机自启...

Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /etc/systemd/system/docker.service.

docker安装成功...

Docker version 23.0.6, build ef23cbc

[root@localhost docker-run-envirment]# docker ps

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

安装完成！

二、docker-compose安装

1、安装docker-compose

注意：要安装其他版本的Compose，可以将1.29.2替换为要安装的Compose版本

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2、申请可执行权限

$ sudo chmod +x /usr/local/bin/docker-compose

3、查看docker-compose版本

$ docker-compose --version
