RHC

基本环境配置

在node节点上添加paas平台的域名地址

一定要做这一步，不然后面会报错！！！
现在webconsole网页上设置指定主机名,如：broker
在 /etc/hosts添加PaaS平台的IP

1

[root@node ~]# vi /etc/hosts
192.168.200.124 broker.xdpaas.com   #broker的IP
192.168.200.125 node
192.168.200.127 gitserver

配置RHC

  1. 安装Gem工具

    1
    [root@node ~]# yum -y install rubygems

  2. 安装RHC工具

  • 将paas光盘下的rhc目录文件拷贝到node上的/tmp/rhc

    mkdir /tmp/rhc

    cd /tmp/rhc

    [root@node rhc]# wget -r -nd ftp://192.168.200.10/paas/rhc/

    [root@node rhc]# gem install --local rhc-1.32.2.gem
    会有一次报错，重复执行该命令即可！

  • 配置RHC
    [root@node rhc]# rhc setup --server=broker.xdpaas.com

    注意要在Paas平台搭建完成后,才能进行RHC运维.

提示：

[root@node rhc]# rhc setup –server=broker.xdpaas.com

密码是paas平台的登入帐号:adminpass和密码:PasswOrd

OpenShift Client Tools (RHC) Setup Wizard

This wizard will help you upload your SSH keys, set your application namespace, and check that other programs like Git
are properly installed.

The server's certificate is self-signed, which means that a secure connection can't be established to
'broker.xdpaas.com'.

You may bypass this check, but any data you send to the server could be intercepted by others.

Connect without checking the certificate? (yes|no): yes

Login to broker.xdpaas.com: adminpass

Password: ****

OpenShift can create and store a token on disk which allows to you to access the server without using your password.
The key is stored in your home directory and should be kept secret.  You can delete the key at any time by running 'rhc
logout'.

Generate a token now? (yes|no) yes

Generating an authorization token for this client ... lasts about 23 hours

Saving configuration to /root/.openshift/express.conf ... done

No SSH keys were found. We will generate a pair of keys for you.

    Created: /root/.ssh/id_rsa.pub

Your public SSH key must be uploaded to the OpenShift server to access code. Upload now? (yes|no) yes

  default (type: ssh-rsa)
  -----------------------
    Fingerprint: 6f:c5:f8:ac:37:82:97:bf:b9:c5:73:04:0a:a5:0d:2a

  rhc (type: ssh-rsa)
  -------------------
    Fingerprint: 20:df:b2:00:77:ef:a7:1a:bc:79:35:58:72:24:d2:81

You can enter a name for your key, or leave it blank to use the default name. Using the same name as an existing key
will overwrite the old key.

Provide a name for this key: |adminpassgitserv| rhc

**创建python:**

[root@node rhc]# rhc app-create pythonapp python-2.6

    5
    Deleting domain 'xdpaas' ... Domain contains applications. Delete applications first or set force to true.
    [root@node rhc]# rhc app-delete pythonapp
    This is a non-reversible action! Your application code and data will be permanently deleted if you continue!

    Are you sure you want to delete the application 'pythonapp'? (yes|no): yes

  2. 删除错误的主机

    [root@node rhc]# rhc domain-delete xdpaas

    1

    3
    Creating domain 'broker' ... done
    You may now create an application using the 'rhc create-app' command
    [root@node rhc]#

  4. 重新在正确的主机下，新建应用：

[root@node rhc]# rhc app-create pythonapp python-2.6
