## 准备主机、操作系统、配置操作系统、主机映射等 ##

## OpenShift平台使用的容器引擎为Docker，安装Docker软件 ##

## 启动服务，并设置为开机自启动 ##

[root@node01 ~]# systemctl start docker
    [root@node01 ~]# systemctl enable docker
    Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

## 运行一个DockerHub的镜像，启动一个go语言的小程序监听8080及8088端口 ##

[root@node01 ~]# docker run -it openshift/hello-openshift
    Unable to find image 'openshift/hello-openshift:latest' locally
    latest: Pulling from openshift/hello-openshift

## 下载openshift-origin-server-v1.5.1-7b451fc-linux-64bit.tar.gz,解压后重命名 ##

[root@node01 app]# tar -zxvf /app/install/openshift-origin-server-v1.5.1-7b451fc-linux-64bit.tar.gz

## 将OpenShift相关命令加入PATH，/etc/profile中添加，也可在bash\_profile中添加 ##

[root@node01 app]# vim ~/.bash_profile
    
    # .bash_profile
    
    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
            . ~/.bashrc
    fi
    
    # User specific environment and startup programs
    export OPENSHIFT_HOME=/app/openshift
    PATH=$PATH:$HOME/bin:OPENSHIFT_HOME/
    
    export PATH

## 执行source使配置生效。 ##

[root@node01 app]# source ~/.bash_profile

## 执行openshift version 查看当前版本，测试是否成功。 ##

[root@node01 app]# openshift version
    openshift v1.5.1+7b451fc
    kubernetes v1.5.2+43a9be4
    etcd 3.1.0

## 进入/app/openshift目录，执行openshift start命令启动OpenShift Origin。 ##

[root@node01 openshift]# openshift start
