Docker安装及配置家目录

安装依赖

yum install -y yum-utils device-mapper-persistent-data lvm2

安装下载源

yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装docker

yum -y install docker-ce

创建目录

/home/dockerfile

修改默认目录

vim /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd --data-root /home/dockerfile -H fd:// -H tcp://0.0.0.0:2375 --containerd=/run/containerd/containerd.sock

启动docker

systemctl  daemon-reload 
systemctl  start docker.service
systemctl  enable docker.service

若无法启动则修改 –data-root 为–graph

ExecStart=/usr/bin/dockerd --graph /home/dockerfile -H fd:// -H tcp://0.0.0.0:2375 --containerd=/run/containerd/containerd.sock

再起重启docker

systemctl  daemon-reload 
systemctl  start docker.service
systemctl  enable docker.service
