... 10 more原因：
tomcat的lib目录下已经存在servlet-api.jar，jersey库的ext目录下也含有一个javax.servlet-api-3.0.1.jar，推测这两个jar包冲突了，可以去掉其中一个。
一不小心又到中秋节了！昨天上午依旧十分忙碌的工作，完全没想起再过一天就是节假日，直到下班前才突然醒悟~
这几天项目中的web服务应客户的需求要加入https相关的机能，因为组里面只有我一个人或多或少接触了一点点https的东西，所以老大就把这个任务全权交给我一个人来处理了。过程十分的艰辛，说实话里面涉及到东西实在太多，openssl，keytool，java版本限制，tomcat限制，加密套件，DHparameter等等，每个东西都能把我折磨的半死。眼下有了一些眉目，正好趁这个假日好好整理一下，学着费劲，所以可能就格外珍惜吧。
利用packstack工具安装openstack的过程中，发生如下错误：
ERROR : Error appeared during Puppet run: 10.167.14.164_cinder.pp
Error: cinder type-create iscsi returned 1 instead of one of [0]原因:
cinder组件在上一次的安装过程中已经创建了iscsi的类型
在给pacemaker添加ipv6类型的resource agent的时候发生错误，错误信息如下：
Failed actions:
ipv6-vip-master_start_0 on node2 'unknown error' (1): call=542, status=complete, exit-reason='[findif] failed', last-rc-change='Tue Mar 29 17:12:33 2016', queued=0ms, exec=72ms从错误信息可以看出出错原因是findif failed，意思是无法找到所加ip对应的网卡，于是检查自己的网卡信息，在我的服务器上，ipv6所在网卡为ens9：
刚安装完的openstack，在dashboard上出现该错误，并且无法修改volume的配额。
openstack版本：Liberty
OS版本：Redhat 7.2
修改方法如下：
在文件/etc/cinder/cinder.conf中追加以下内容

该方法同时支持ipv4和ipv6，检查ip是否在指定的cidr内。
实现代码为java。
