一、关闭SELINUX

setenforce 0
sed -i  "s/SELINUX=enforcing/SELINUX=permissive/g" /etc/selinux/config

二、安装docker
1、配置源

cat <<END >/etc/yum.repos.d/repo.repo
[repo]
name=repo
baseurl = https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/7/x86_64/stable/
enabled=1
gpgcheck=0
END

2、安装docker-ce

yum install docker-ce

3、配置国内源

# mkdir -p /etc/docker
#  tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://***.mirror.aliyuncs.com"]
}
EOF

4、启动docker

systemctl enable docker
systemctl start docker

三、安装openshift
1、下载地址：https://github.com/openshift/origin/releases

2、上传到/opt目录

mv openshift-origin-server-v3.11.0-0cbc58b-linux-64bit.tar.gz /opt

3、解压

cd /opt
tar -zxvf openshift-origin-server-v3.11.0-0cbc58b-linux-64bit.tar.gz

4、目录太长，创建一个软链接

ln -s openshift-origin-server-v3.11.0-0cbc58b-linux-64bit /opt/openshift

5、 修改/etc/profile，加入环境变量

PATH=$PATH:/opt/openshift/

执行生效

# source /etc/profile

6、启动集群

oc cluster up --skip-registry-check=true --public-hostname=”10.10.10.114”

启动完成出现

The server is accessible via web console at:
    https://10.10.10.114:8443

You are logged in as:
    User:     developer
    Password: <any value>

To login as administrator:
    oc login -u system:admin

7、配置防火墙

firewall-cmd --zone=public --add-port=8443/tcp --permanent

重新载入防火墙

firewall-cmd --reload

8、浏览器访问 https:// 10.10.10.114:8443
