The Apache Tomcat installation at this directory is version 8.5.6A Tomcat 8.0 installation is expect
1.在eclipse中安装tomcat8.5时，报错：
The Apache Tomcat installation at this directory is version 8.5.6. A Tomcat 8.0 installation is expected.
2.解决办法：
Windows中
①在Tomcat的安装目录中找到lib目录，再找到catalina.jar。使用压缩软件（WinRAR或是好压）打开它。 ②依次找到并双击打开org\apache\catalina\util\ServerInfo.properties 文件
server.info=Apache Tomcat/8.5.6 server.number=8.5.6.0 server.built=Oct 6 2016 20:15:31 UTC
改为：
#Apache Tomcat/8.5.6
server.info=Apache Tomcat/8.0.0
#8.5.6.0
server.number=8.0.0
server.built=Oct 6 2016 20:15:31 UTC
在Linux中改法：
cd [tomcat or tomee home(tomcat目录)]/lib mkdir catalina cd catalina/ unzip ../catalina.jar vim org/apache/catalina/util/ServerInfo.properties `把版本号改成如下形式:` server.info=Apache Tomcat/8.0.0 server.number=8.0.0 server.built=May 11 2016 21:49:07 UTC 接着把改好的ServerInfo.properties文件添加到catalina.jar中: jar uf ../catalina.jar org/apache/catalina/util/ServerInfo.properties cd .. rm -rf catalina
