在 AWS 控制台中搜索资源是一项艰巨的任务。这个答案帮助我找到了我不认识的已使用资源（例如我从未使用过的区域）。幸运的是账单仍然是 0。但我宁愿清理桌子。一个一个地删除一个资源是非常乏味的并且需要很多时间。有没有一些简单的方法（除了关闭帐户）如何删除所有使用的资源？

我有一台带有多个 tomcat 应用程序的 Azure 机器。我正在配置它们并重新启动它们，直到突然带有 jasper 的 tomcat 在部署时停止。没有错误，最后一句是

Jun 18 16:49:10 RE1 catalina.sh: 18-Jun-2020 16:49:10.273 INFO [main] org.apache.catalina.core.StandardEngine.startInternal Starting Servlet Engine: Apache Tomcat/8.0.23
Jun 18 16:49:10 RE1 catalina.sh: 18-Jun-2020 16:49:10.281 INFO [localhost-startStop-1] org.apache.catalina.startup.HostConfig.deployDirectory Deploying web application directory /opt/app/jasper/apache-tomcat-8.0.23/webapps/jasperserver

我发现这可能是熵丢失造成的，所以我修改了JAVA_OPTS：

export JAVA_OPTS="-Xmx2048m -Djava.security.egd=file:/dev/./urandom"

好吧，它没有帮助。这是线程转储的一部分。知道如何解决这个问题吗？

我发现要将 LUA 与 Nginx 一起使用，我需要：

我想知道如何构建模块本身，然后将其加载到打包的 Nginx 中。我不愿意构建 Nginx，因为这意味着我会丢失包更新。我怎样才能做到这一点？
