CAS之5.2x版本存储Ticket到redis-yellowcong

默认情况下，cas是将票据信息存储到内存中，我们可以将票据存储到redis服务器中,cas采用的spring data redis 来控制redis,将票据存储到redis需要两个步骤：1、配置cas关于redis的依赖,2、配置application.properties，添加redis的配置信息。就两部，就完成了redi与cas的搞基。

搭建redis环境

我这个本来是window的，我也懒得搞linux的redis了，直接就window上面搞了。如过想看linux的可以参考文章Redis之单机安装-yellowcong

#window下载安装包 http://yellowcong.qiniudn.com/redis-windows-master.zip[/code]

配置redis到cas
跟多配置可以查看管网：https://apereo.github.io/cas/5.2.x/installation/Configuration-Properties.html#redis-ticket-registry

1、不设定密码的情况
这个地方配置的时候，redis没有设置密码。

##redis的服务器地址
cas.ticket.registry.redis.host=127.0.0.1
#
## 选择第一个redis数据库
cas.ticket.registry.redis.database=0
#
## redis端口
cas.ticket.registry.redis.port=6379


2、设置密码的情况
##redis的服务器地址
cas.ticket.registry.redis.host=127.0.0.1
#
## 选择第一个redis数据库
cas.ticket.registry.redis.database=0
#
## redis端口
cas.ticket.registry.redis.port=6379

#redis密码
cas.ticket.registry.redis.password=yellowcong
#超时设置
cas.ticket.registry.redis.timeout=2000
cas.ticket.registry.redis.useSsl=false
#不设置redis线程池
cas.ticket.registry.redis.usePool=false


这个密码需要和redis的配置一致，如果没有密码，可以不用设置。



测试登录
我们先通过网站登录，然后手动清空session，通过 
flushall
清空session里面的数据，看服务器是否session退出，然后跳转到登录界面。
