这是工作/测试说明：

1)列出tomcat7的包

dpkg --get-selections | grep tomcat7

为了以防万一,您可能还希望列出包含tomcat的软件包(dpkg –get-selections | grep tomcat).

2)删除你看到的所有包裹！仅当您删除单个包时 – >注意其依赖关系,如果包A依赖于B,则需要同时删除B和A,然后按B顺序删除A – 删除所有包的示例如下：

sunyang@127:/var/www/html/sun_ios_api/lollicupStore2/app/etc$
sunyang@127:/var/www/html/sun_ios_api/lollicupStore2/app/etc$ dpkg -P libtomcat7-java tomcat7 tomcat7-admin tomcat7-common tomcat7-docs tomcat7-examples

3)Ubuntu不会删除非空目录,例如配置文件.所以你必须手动删除它.搜索遗留的文件并将其删除.例：

find / -name "*tomcat7*"

然后删除它们示例：rm -r / etc / tomcat7 / var / cache / apt / archives / tomcat7 * / var / cache / apt / archives / libtomcat7 * / tmp / hsperfdata_tomcat7

完成！现在全部清理干净了.
