At present, OpenShift has launched the 4.2 version, and I am ready to learn about OpenShift. I have referred to OpenShift Open Source Container Cloud, but the installation process is really a series of twists and turns, which is hereby recorded.

1. Prepare the environment of VMware virtual machine RHEL7.4

Each time you start the virtual machine, you have to start the network manually. Do you know how to set it to automatically connect to the network when you start the virtual machine

2. Set the mirror source

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/$basearch/
yum clean all
yum makecache
yum update

When I set the mirror source, I used Tsinghua’s mirror source, but there is a variable $releasever in it that may not be found, so manually change it to 7 and then yum can be connected three times

3. Download the openshift

cd /opt/
wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-server-v3.11.0-0cbc58b-linux-64bit.tar.gz

OpenShift Server source package to /opt directory, on GitHub the current stable version is 3.1.1,

4. Unzip and install

Tar ZVF openshift-origin-server-v3.11.0-0cbc58b-linux-64bit.tar.gz ln -s Openshift origin - server - v3.11.0-0 cbc58b - Linux - 64 - bit. The tar. Gz/opt/openshift

Set up a soft connection and use the /opt/opeshif directory next time, then add it to the environment variable and change /etc/profile to use the openshift command

PATH=$PATH:/opt/openshift

5. Start the openshift

There are a lot of problems here

The first boot failed

Unable to start with OpenShift Start will cause an error. This command is deprecated and will need to be started with OC Cluster Up

Command "start" is deprecated, This command will be replaced by the hypershift and hyperkube binaries for starting individual components.
Start components of OpenShift 

This command launches components of OpenShift.

The second boot failed

Failed to start Kube-Apiserver using OC Cluster Up

I1119 23:43:45.311335 18475 run_self_host. go:181] Waiting for the Kube-Apiserver to be ready... E1119 23:48:45. 514801 18475 run_self_hosted.

I did a bit of digging and found that the firewall needs to be turned off

firewall-cmd --state
systemctl stop firewalld.service
systemctl disable firewalld.service

The third boot failed

The fourth boot failed

Restart or fail

OC Cluster Up — skip-registrie-check =true This may be because I started with OC Cluster Up — skip-registrie-check =true

The fifth boot failed

Let’s start it up again

Failed to install "openshift-image-registry": could not run "openshift-image-registry": rc=1

I didn’t find out the reason this time. Could it be the network problem

The sixth boot failed

Let’s start it up again

The seventh boot failed
