离线安装docker
一． 使用WinSCP上传docker离线包
二． 将docker离线包解压并移动到/usr/bin下
tar -xvf docker-18.06.1-ce.tgz
cp docker/* /usr/bin/
三． 添加docker配置文件
vi /etc/systemd/system/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
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
四． 启动docker
chmod +x /etc/systemd/system/docker.service
systemctl daemon-reload
systemctl start docker
systemctl enable docker.service
docker ps #验证docker是否正常启动
如图所示，离线安装docker成功。
五． Docker加速
vi /etc/docker/daemon.json
加入一下内容
{
"registry-mirrors": ["https://registry.docker-cn.com"]
}
重启docker即可。
