404错误 - Jenkins没有运行，但Tomcat是

Question

我是这个领域的新人。我看到Tomcat服务正在运行。

我通过输入网址http://localhost:8080验证了这一点。

但是当我输入http://localhost:8080/jenkins时，我收到404错误。

我已验证<TOMCAT_HOME>/webapps/jenkins.war的可用性。

这是否意味着我必须重新安装 Tomcat和Jenkins ？或者还有什么我需要做的事情吗？

更新：

我从这里下载了jenkins.war版本1.658 - https://updates.jenkins-ci.org/download/war/并用相对较新的版本（版本1.658）替换旧的jenkins.war（版本1.568）。当我尝试http://localhost:8080/jenkins -

时，我收到了带有stacktrace的错误消息

安装的jdk存在差异。

更多信息：如果要升级jdk版本，则必须擦除旧版本的jdk并卸载Jenkins。如果您通过Tomcat运行Jenkins，则必须卸载它，并且必须重新安装所有内容。
