我有一個servlet應用程序，我試圖部署到我的本地tomcat實例。起初我嘗試使用Tomcat管理器應用程序部署，但被告知有一個更簡單的方法 - 只需在webapps -folder丟棄.war（/etc/tomcat8/webapps/我的機器上）在tomcat8啓動.war servlet
在重新啓動Tomcat服務，但是我得到一個錯誤：
Job for tomcat8.service failed because the control process exited with error code. See "systemctl status tomcat8.service" and "journalctl -xe" for details.
journalctl -xe輸出如下：

我懷疑這是在我的本地環境（這是新安裝的）的配置錯誤，但無法弄清楚究竟是什麼 有可能！我嘗試重新安裝，但過了一段時間，我又一次陷入了同樣的死衚衕......任何想法？
編輯：這裏是來自systemctl status tomcat8.service輸出：

開始的幾件事：1.如果沒有webapps中的新war文件，tomcat會啓動嗎？ 2.您是否檢查了tomcat，Catalina.log和localhost日誌文件中'logs'目錄中的tomcat日誌。 –
catalina.log舉行答案！以前不知道這個！ –
