安装完zookeeper后启动服务端报错如如上

错误信息很明显说了地址已经被占用，以为一般的tomcat默认设置了自动部署，需要修改tomcat的 server.xml 属性

我用的tomcat7，默认配置如下

[html] view plain copy

  1. <**Host appBase=”webapps” autoDeploy=”true” name=”localhost” unpackWARs=”true”>**

修改为

[html] view plain copy

  1. <**Host appBase=”webapps” autoDeploy=”false” deployOnStartup=”false” name=”localhost” unpackWARs=”true”>**

在启动就好了。

注意：如果是在eclipse中修改你项目栏左侧server离得server.xml ,开始我修改的是我安装tomcat的硬盘的文件，每次都会自动还原成默认
