1、我是新建的server，用来启动服务，报错儿：java.net.ConnectException: Connection timed out: no further information
net.spy.memcached.MemcachedConnection: Reconnecting due to failure to connect to {QA sa=/211.212.102.212:11211, #Rops=0, #Wops=0, #iq=0, topRop=null, topWop=null, toWrite=0, interested=0}
java.net.ConnectException: Connection timed out: no further information；

2、从详细报错信息上，是Memcach的问题，详细查看项目中配置，并无此项配置，后来发现server中的context.xml文件中有：如下配置：
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" customConverter="cn.cnnic.kryoSerialize.CustomKryoRegistration" lockingMode="none" memcachedNodes="n1:211.212.102.212:11211" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" sessionBackupAsync="false" sessionBackupTimeout="1800000" sticky="false" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"/>
context.xml文件的目录如下：
3、这里把上述context.xml文件中关于 memach的配置项删掉即可。
