CactiEZ中文版10.1与CAS单点登录

环境

CactiEZ中文版10.1为网上下载的镜像，344MB，该镜像是精简的CentOS6.0的版本。

cas phpClient为1.3.3，详细的使用说明及下载最新版本可以点击此处

在虚拟机安装的CactiEZ中文版10.1镜像，地址为:192.168.217.130，使用NAT方式访问，DHCP获取的IP地址(如果想访问外网，可以将系统自带的网关删掉，我安装之后的默认网关是192.168.0.1，删了之后就能正常上网了)

过程

1.将下载下载的CAS-1.3.3.tgz解压文件中的/CAS文件夹和CAS.php复制到/ver/www/html/目下。

2.在/ver/www/html/目下创建一个ssoLogin.php，该名字不是可以随便起，也可以直接修改index.php文件，将原来的内部登录方法屏蔽掉。

代码如下：

// Load the cactiEZ lib

require_once 'CAS.php';

phpCAS::setDebug();

// Initialize phpCAS

// For production use set the CA certificate that is the issuer of the cert
// on the CAS server and uncomment the line below
// phpCAS::setCasServerCACert($cas_server_ca_cert_path);

// THIS SETTING IS NOT RECOMMENDED FOR PRODUCTION.

phpCAS::setNoCasServerValidation();

// at this step, the user has been authenticated by the CAS server
// and the user's login name can be read with phpCAS::getUser().

// logout if desired

使用浏览器访问 192.168.217.130/ssoLogin.php，见证奇迹的时候就要到了，如果是chrome，就是白屏，毛也没有，如果是IE还正常提示500错误，解决该问题花费了N长时间啊，原因很简单，精简的镜像文件缺少php-dom，而php Client依赖该文件，最简单的方法是直接安装

#yum install php-dom

系统会在网上搜索安装包，安装完之后重启httpd服务就可以正常了。

如果没有网络也没关系，找个CentOS6 X86的镜像，将该镜像作为yum的源安装，

2）mount CenotOS光驱(系统为CentOS6 X86)，

$mount /dev/cdrom /media/cdrom/

3）然后配置yum数据源，修改/etc/yum.repos.d/目录下的文件

$cp /etc/yum.repos.d/CentOS_Base /etc/yum.repos.d/CentOS_Base.bak

屏蔽掉默认的网络升级方法
修改/etc/yum.repos.d/CentOS_Media
$vim /etc/yum.repos.d/CentOS_Media

$vim /etc/yum.repos.d/CentOS_Media

将其中的enable修改为1
测试效果

$yum list

4）然后安装php-dom

yum -y install php-dom

5）最后重启服务

$service httpd restart

以上就是整个实现的思路，其中配置文件可能跟实际过程略有出入。
