最近在阿里云服务器上装tomcat，一开始为了省事直接使用了apt-get安装，结果整个程序被拆开散到了好多地方，尤其是像网上说要把打包好了.war文件放到webapps文件夹下，但是开始并没有在/usr的相关目录下找到，即使后面找到了相关文件，但是等到运行/startup.sh的时候却发现在日志文件里出现了下面的内容：

摔，以第四行的server.xml找不到为例，因为apt-get的方法在下载的时候把server.xml放到了/etc/tomcat8里面而startup.sh则放到了/usr/share/tomcat8下，所以实际上根本就没法正常运行，如果要运行就需要改很多地方，所以不如直接删除后放弃，使用别的方式来的更快一些。
不过在这里还是给大家分享一下我找到的apt-get下载的东西都分布在哪里，这样大家到时候如果要删除的话也会更方便（可能不全欢迎大家帮忙补充）：
/usr/share/tomcat8
etc/tomcat8 这里主要是一些配置文件（本来etc也是存放配置的）
var/lib/tomcat8/ 这里主要是存放webapps等文件
所以总的来说还是推荐大家去官网下载，也并不大，大概10MB左右，下载下来以后把它上传到服务器上，然后找一个人地方解压就好了，不过这个需要注意解决防火墙问题，输入
/sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT
即可。
