Centos8 下离线安装部署docker 、docker-compose

docker 离线安装部署

下载地址

https://download.docker.com/linux/static/stable/x86_64/
这里可以下载你实际使用到的版本

我使用的是docker-20.10.9-ce.tgz

解压命令

tar -zxvf docker-20.10.9-ce.tgz

解压之后的文件复制到 /usr/bin/ 目录下

cp docker/* /usr/bin/

在/etc/systemd/system/目录下新增

docker.service

文件

通过 vi docker.service 进入文件编辑模式，粘贴如下代码。

[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 dockerExecStart=/usr/bin/dockerd --selinux-enabled=false
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=infinityTimeoutStartSec=0# set delegate yes so that systemd does not reset the cgroups of docker containersDelegate=yes
# kill only the docker process, not all processes in the cgroupKillMode=process
# restart the docker process if it exits prematurelyRestart=on-failure
StartLimitBurst=3StartLimitInterval=60s
  
[Install]WantedBy=multi-user.target

启动docker

#给docker.service文件添加执行权限chmod +x /etc/systemd/system/docker.service
#重新加载配置文件（每次有修改docker.service文件时都要重新加载下）
systemctl daemon-reload   
#启动docker
systemctl start docker
设置开机启动
#systemctl enable docker.service#查看docker服务状态
systemctl status docker

docker-compose 离线安装

首先下载离线文件

https://github.com/docker/compose/releases

选择自己对应的版本进行下载

上传至服务器之后，将文件迁移到这个位置将文件转移至/usr/local/bin/

mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose

添加权限：

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

检查状态

docker-compose -v
