centos7搭建openshift-3.11

关闭防火墙和selinux

sed -i "s/SELINUX=enforcing/SELINUX=permissive/g" /etc/selinux/config 
systemctl stop firewalld 
systemctl disable firewalld

安装docker

yum install -y yum-utils 
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo 
yum -y install docker-ce

配置docker私有仓库地址

因为openshift安装成功后，会自行启动一个registry的私有仓库镜像以便使用，为了之后不用重新配置后还要重启docker，所以在此先行配置

集群自动启动的registry仓库地址就是172.30.x.x，所以如下配置

systemctl start docker
vim/etc/docker/daemon.json
{
  "insecure-registries": ["172.30.0.0/16"]
}
systemctl daemon-reload
systemctl restart docker
systemctl enable docker

安装包：
https://github.com/openshift/origin/releases/tag/v3.11.0

上传到安装目录，我当前是使用的root目录
解压缩并且重命名：

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

修改/etc/profile，加入环境变量

PATH=$PATH:/opt/openshift-server-v3.11.0/ 
source /etc/profile

启动集群

oc cluster up --skip-registry-check=true --public-hostname="192.168.30.17" --no-proxy="192.168.30.17"

参数介绍：


skip-registry-check 代表是否跳过Docker守护进程注册表什么的检查
public-hostname 代表暴露在外部供访问的地址
no-proxy 代表哪些地址不需要转发（如果不加这个，有可能部署成功后访问地址会转发到 localhost 127.0.0.1）

启动成功的最后会有这个输出
