一、下载二进制docker包、解压、拷贝文件
# wget https://download.docker.com/linux/static/stable/x86_64/docker-18.09.6.tgz
# tar xf docker-18.09.6.tgz
# cp docker/* /usr/bin/
# docker version

# vi /usr/lib/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 ExecStart=/usr/bin/dockerd ExecReload=/bin/kill -s HUP $MAINPID LimitNOFILE=infinity LimitNPROC=infinity TimeoutStartSec=0 Delegate=yes KillMode=process Restart=on-failure StartLimitBurst=3 StartLimitInterval=60s [Install] WantedBy=multi-user.target |
# systemctl daemon-reload
# systemctl start docker
# ps -ef|grep docker
