linux 离线安装docker
很多情况下我们不能对docker进行在线安装，这时可以参照本篇博客尝试进行离线安装docker-ce
1.下载对应版本的安装包
2.解压安装包
tar -zxvf docker-XXX.tgz
3. 将解压的文件复制到指定位置
cp ./docker/* /usr/bin
4.配置docker服务的文件如下
cd /etc/systemd/system/
vim docker.service
[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 --insecure-registry=192.168.205.230
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
5. 加载启动docker
chmod +x docker.service
systemctl daemon-reload
systemctl start docker
systemctl enable docker.service
6.查看版本
docker -v
dockier -info
