java无法联系localhost:8005。关闭Tomcat时，Tomcat可能未运行错误

Question

嗨，我正在尝试关闭和启动tomcat服务器。但在运行关机时，我得到了以下错误。请检查以下错误并建议我完成

错误：

试着从一开始/卡塔琳娜。申润 如果一切正常，它就会出现在屏幕上 否则会显示一些错误 就像我的情况一样

更改内存堆大小，它肯定会工作

Answer 2

您可以尝试添加 导出JRE_HOME=$JAVA_HOME/JRE 在/etc/profile中，然后运行 来源/etc/profile 这对我来说是可行的

Answer 3

如果时间戳正确，则表明您的tomcat启动在23:00左右失败，并且您试图在11:00关闭不存在的tomcat服务

Answer 4

有些应用程序在端口8005上运行，因此tomcat无法在端口上绑定网络。你的关机。sh将引发异常，因为服务器尚未启动（因为启动服务器时出现问题）

• 解决方案1（推荐）：将/opt/tomcat8/conf/server中的端口从8005更改为8006。xml
• 解决方案2：请通过netstat -tulnp | grep 8005检查哪个应用程序正在使用8005并将其关闭

Answer 5

http://blog.51cto.com/zero01/2053974。我今天遇到了同样的问题。当我想执行shudown时。sh，日志显示tomcat可能没有运行，与端口8005的连接被拒绝。当我使用netstat-atunp时，我发现没有进程侦听端口8005。所以tomcat应该无法启动。我搜索，并在下面显示的链接中找到答案。关键是要更改此文件

$JAVA_HOME/jre/lib/security/java.security

要更改的数据是在“random”之前添加字符“u”

securerandom.source=file:/dev/random

securerandom.source=file:/dev/urandom

它是有效的。但我不知道为什么？。有人能告诉我吗？希望这能帮助其他人
