【问题讨论】：

请引用或缩进日志以便更好地阅读:)
@Patrizio Bertoni...我已经给出了日志文件的详细信息。你现在能帮我吗
你已经停止了它。日志文件证明了这一点。

标签： java apache tomcat

【解决方案1】：

我刚刚在另一个问题下回答了这个问题。

我今天解决了，可能是 jdk-1.8.x 的一个错误。

比如我的jdk路径是"/usr/java/jdk1.8.0_144"。

cd /usr/java/jdk1.8.0_144/jre/lib/security/

找到名为“java.security”的文件，

vi java.security

找到“securerandom.source=file:/dev/random”。

修改“securerandom.source=file:/dev/./urandom”。

然后，进入Tomcat/bin目录，执行./start.sh和./shutdown.sh，发现一切正常。

【讨论】：

几乎花了一天时间才弄清楚这一点。最后尝试了这个，它成功了。不知道为什么会这样。据我所知，除了在 GCP 中调整磁盘大小之外，我没有做太多事情。无论如何，它解决了痛苦。谢谢
你是怎么想出来的！？

【解决方案2】：

请确保服务器启动后服务器端口没有改变！

更改正在运行的服务器的服务器端口可能使其无法关闭，并显示如下错误消息：

06-Feb-2018 10:17:10.682 SEVERE [main] org.apache.catalina.startup.Catalina.stopServer Could not contact [localhost:[8005]]. Tomcat may not be running. 06-Feb-2018 10:17:10.693 SEVERE [main] org.apache.catalina.startup.Catalina.stopServer Catalina.stop: java.net.ConnectException: Connection refused: connect

【讨论】：

【解决方案3】：

这是 jdk 1.8.x 中的一个错误 - 以下是如何修复它：

在 Windows 资源管理器中，导航到 JRE --> lib -->security
打开文件java.security
在此文件中找到“securerandom.source=file:/dev/random”
将其替换为：“securerandom.source=file:/dev/./urandom”

然后，从tomcat的bin文件夹中运行以下命令：

一个。启动服务器：

startup.bat 或 catalina.bat start

b.停止你的服务器：

shutdown.bat 或 catalina.bat stop

希望这会对你有所帮助。

【解决方案4】：

错误 - 端口 8080 是您的应用程序/tomcat 将服务的端口。如果更改它，则不会出现问题，因为特殊端口 8005 用于关闭。

【讨论】：

【解决方案5】：

这是因为您在端口上启动了tomcat并且您试图在另一个端口上关闭，解决方案是更改默认的tomcat关闭端口8085，所以如果您在端口8080上启动了tomcat服务器，请继续/tomcat /server.xml 文件并更改此文件

<Server port="8085" shutdown="SHUTDOWN">

到

<Server port="8080" shutdown="SHUTDOWN">

真诚的

【讨论】：

更改端口无关紧要。 8005端口用于关闭服务器，8080端口用于启动。

【解决方案6】：

更改 java.security 并不能解决我的问题，在这种情况下，通过 PID 杀死会有所帮助。在Linux中要归档你需要做的以下目标：

lsof -i:8005(端口号)
杀死 PID
