Centos7.6 使用二进制安装docker

创建Docker二级制文件存放目录

mkdir /opt/kube/bin/ -pv

# lltotal 155108-rwxr-xr-x 1 root root 37598450 Sep 19 11:10 docker-rwxr-xr-x 1 root root 11748168 Sep 19 11:13 docker-compose-rwxr-xr-x 1 root root 26393752 Sep 19 11:13 docker-containerd-rwxr-xr-x 1 root root 14725592 Sep 19 11:13 docker-containerd-ctr-rwxr-xr-x 1 root root  4173632 Sep 19 11:13 docker-containerd-shim-rwxr-xr-x 1 root root 53076360 Sep 19 11:11 dockerd-rwxr-xr-x 1 root root   764144 Sep 19 11:13 docker-init-rwxr-xr-x 1 root root  2837280 Sep 19 11:13 docker-proxy-rwxr-xr-x 1 root root  7495056 Sep 19 11:13 docker-runc

配置启动文件

# vim /etc/systemd/system/docker.service[Unit]Description=Docker Application Container EngineDocumentation=http://docs.docker.io[Service]Environment="PATH=/opt/kube/bin:/bin:/sbin:/usr/bin:/usr/sbin"ExecStart=/opt/kube/bin/dockerd ExecStartPost=/sbin/iptables -I FORWARD -s 0.0.0.0/0 -j ACCEPTExecReload=/bin/kill -s HUP $MAINPIDRestart=alwaysRestartSec=5LimitNOFILE=infinityLimitNPROC=infinityLimitCORE=infinityDelegate=yesKillMode=process[Install]WantedBy=multi-user.target

创建软连接

ln -s /bin/docker /opt/kube/bin/docker

启动Docker服务及设置开机启动

sudo systemctl start docker
sudo systemctl enable docker

添加appuser使用权限
sudo usermod -a -G docker appuser
sudo systemctl daemon-reload
sudo systemctl restart docker
newgrp docker
