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 docker
ExecStart=/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=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
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
