安裝完zookeeper後啟動服務端報錯如如上
錯誤資訊很明顯說了地址已經被佔用，以為一般的tomcat預設設定了自動部署，需要修改tomcat的 server.xml 屬性
我用的tomcat8，預設配置如下
<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">修改為
<Host appBase="webapps" autoDeploy="false" deployOnStartup="false" name="localhost" unpackWARs="true">
在啟動就好了。
注意：如果是在eclipse中修改你專案欄左側server離得server.xml ,開始我修改的是我安裝tomcat的硬碟的檔案，每次都會自動還原成預設
