选择操作系统版本

[root@localhost ~]# cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core)

配置网卡

固定ip地址，开机激活忘啦,并且能够联网

TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=76fc1a45-394d-45bb-8796-6b449d0a77bb
DEVICE=ens33
ONBOOT=yes
GATEWAY=192.168.100.2
DWADDR=00:0c:29:b9:b3:a6
IPADDR=192.168.100.128
DNS1=114.114.114.114
DNS2=8.8.8.8

配置源

由于国内的源比较卡，所以我们推荐使用daocloud的方式

curl -sSL https://get.daocloud.io/docker | sh

配置镜像

国内通常默认docker hub的网速不稳定，可以配置daocloud提供的docker hub

[root@localhost ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://681a96df.m.daocloud.io
docker version >= 1.12
{"registry-mirrors": ["http://681a96df.m.daocloud.io"]}
Success.
You need to restart docker to take effect: sudo systemctl restart docker

查看自己配置的docker hub

[root@localhost ~]# cat /etc/docker/daemon.json
{"registry-mirrors": ["http://681a96df.m.daocloud.io"]}

重启docker

systemctl restart docker

重新加载service文件，并且重启docker服务

[root@bogon ~]# systemctl daemon-reload
[root@bogon ~]# systemctl restart docker

连接远程执行docker命令
[root@bogon ~]#  docker -H 192.168.100.129:2375 images
