Java Tomcat 8.5.31在部署战争时卡住了

我们正在将应用程序从tomcat 7迁移到tomcat 8。所有战争都在tomcat 8中成功部署。但只有一场战争没有展开。Tomcat8开始部署战争，然后就被困在那里。Catalina.out和Error.log中没有打印日志

请查看以下日志

这是Catalina.out的最后一行。

以防您仍然需要帮助

如果您使用的是VM，请尝试在setenv.sh文件中设置Djava.security.egd=file:/dev//uradomns

您是否尝试读取日志？您是否看到消息

无法为部署创建目录：[/opt/apache-tomcat-8.5.31/conf/Catalina/localhost]

？可能是权限问题。尝试创建文件夹

/opt/apache-tomcat-8.5.31/conf/Catalina/localhost

并执行

chmod 777/opt/apache-tomcat-8.5.31/conf/Catalina/localhost

Hi@JimGarrison。我已经解决了你提到的问题。仍然有同样的问题。嗨@DanilaZharenkov。我已编辑了“我的问题”，并附上了最新日志。对请求的目录执行chmod 777。仍然面临相同的问题。新日志不包含阻止启动的错误。
