最佳答案

我假设您没有以 root 身份运行 eclipse。但是，您的“手动启动”代码意味着您的手动启动是作为 root 执行的。这通常会导致许多工作文件、临时文件和其他文件归 root 所有，非特权用户不可写。

解决方法是更改​​文件的所有权，例如给与您一起执行 eclipse 的用户——通常是您自己的帐户。现在文件已经属于 root，您也必须以 root 身份执行此操作:

sudo chown --recursive yourusername /usr/local/apache-tomcat-8.0.15

(替换您的用户名，当然)

永远不要以 root 身份运行像 tomcat 这样的网络服务器 - 您总是希望它以非特权用户身份运行。否则，tomcat 上的任何安全问题都可能意味着攻击者可以立即获得 root 访问权限
