Configuration Related
Depending on the software provided, Centos7's virtual machine is built with VM, and many commands are not provided because the mirroring provided is to minimize mirroring.Here are some dependent configurations.
Static IP Configuration:
Sample Profile Content
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=7820b169-8f18-4ca4-8478-cd0a4fc8d0ca DEVICE=ens33 ONBOOT=yes IPADDR=192.168.153.88 NETMASK=255.255.255.0 GATEWAY=192.168.153.2 DNS1=114.114.114.114 DNS2=8.8.8.8
Yum source configuration:
Here is the yum source Baidu cloud link I use:

First IP Settings
Because it is a minimal installation, after installation, you need to set up static IP and DNS configurations to connect to the external network before you can connect through the xshell script.
Execute the edit command:
vi /etc/sysconfig/network-scripts/ifcfg-ens33
Adjustments need to be made referring to the Static IP Configuration sample. If you want to copy and paste, you need to comment out the UUID field, otherwise the service will not come up.
After editing, restart the network service by executing the following command:
systemctl restart network
Execute the following command to verify that the IP is set correctly, and you will see the corresponding IP if it is set successfully:
ip a
Second configuration yum
Connecting a virtual machine through an xshell is not detailed here.
The connection successfully executed the following command to close the firewall:
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config setenforce 0 systemctl stop firewalld.service && systemctl disable firewalld.service
Enter the / etc/yum.repos.d directory to execute the following commands:
cd /etc/yum.repos.d && rm -rf *
Then put the two files in ** "Yum Source Configuration"** in the / etc/yum.repos.d directory.How to put it here in no detail, if you don't understand, you can trust me privately.
The following files appear at/etc/yum.repos.d:
[root@weltest yum.repos.d]# ll //Total usage 8 -rw-r--r--. 1 root root 1616 2 June 10:23 CentOS-Base.repo -rw-r--r--. 1 root root 2640 2 June 10:23 docker-ce.repo
Then execute the following command:
[root@weltest yum.repos.d]# yum clean all //Plugin loaded: fastestmirror //Cleaning up software source: base docker-ce-stable extras updates Cleaning up everything Cleaning up list of fastest mirrors [root@weltest yum.repos.d]# yum makecache //Plugin loaded: fastestmirror base | 3.6 kB 00:00:00 docker-ce-stable | 3.5 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/14): base/7/x86_64/group_gz | 165 kB 00:00:03 (2/14): base/7/x86_64/filelists_db | 7.3 MB 00:00:09 (3/14): base/7/x86_64/primary_db | 6.0 MB 00:00:06 (4/14): docker-ce-stable/x86_64/filelists_db | 18 kB 00:00:02 (5/14): docker-ce-stable/x86_64/updateinfo | 55 B 00:00:02 (6/14): base/7/x86_64/other_db | 2.6 MB 00:00:02 (7/14): docker-ce-stable/x86_64/primary_db | 38 kB 00:00:00 (8/14): extras/7/x86_64/filelists_db | 210 kB 00:00:00 (9/14): docker-ce-stable/x86_64/other_db | 111 kB 00:00:00 (10/14): extras/7/x86_64/primary_db | 159 kB 00:00:00 (11/14): extras/7/x86_64/other_db | 103 kB 00:00:00 (12/14): updates/7/x86_64/filelists_db | 4.0 MB 00:00:03 (13/14): updates/7/x86_64/other_db | 481 kB 00:00:00 (14/14): updates/7/x86_64/primary_db | 6.7 MB 00:00:05 Determining fastest mirrors //Metadata cache established [root@weltest yum.repos.d]#
Third install docker-ce via Yum
There are no errors in the first IP setting and the second configuration yum.Install the basic software:
yum install -y net-tools wget lrzsz
After the basic software is installed, you can execute some simple commands: ifconfig, ping, netstat, wget, sz, rz, and so on.
Install docker-ce from the yum source and execute the following commands:
yum install -y docker-ce
After successful installation, execute the command to start the docker:
systemctl start docker
Edit the file: /etc/docker/daemon.json, add the following to the file:
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}
Then execute the command to restart the docker:
systemctl stop docker systemctl reload docker systemctl start docker
Fourth, verify that docker is installed successfully
Execute the docker pull command to pull the mirror, giving the following examples:
root@weltest yum.repos.d]# docker pull alpine Using default tag: latest latest: Pulling from library/alpine c9b1b535fdd9: Pull complete Digest: sha256:ab00606a42621fb68f2ed6ad3c88be54397f981a7b70a79db3d1172b11c4367d Status: Downloaded newer image for alpine:latest docker.io/library/alpine:latest [root@weltest yum.repos.d]# cd ~ [root@weltest ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE alpine latest e7d92cdc71fe 3 weeks ago 5.59MB
