开始后./catalina.sh jpda 启动 我正进入（状态
ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options.
Error occurred during initialization of VM
agent library failed to init: jdwp
我无法在 eclipse 中进行远程调试
但如果我启动正常 tomcat 正在启动
答案1
你应该任何一个设置-Xdebug -Xrunjdwp...JAVA_OPTS 环境变量中的开关，或者将jpda参数传递给catalina.sh，但不能同时传递两者。如果同时传递两者，它将尝试加载代理两次并给出错误。
编辑：我个人更喜欢使用 JAVA_OPTS 开关，因为它们可以提供更多控制（例如设置端口号）。完成此操作并重新启动 Tomcat 后，您应该能够从 Eclipse 连接到调试器。
要从 Eclipse 连接，您需要创建“远程 Java 应用程序”类型的调试配置：从“运行”菜单中，选择“调试配置...”。在左侧窗格中，选择“远程 Java 应用程序”，然后单击“新建”按钮。在右侧窗格中，选择项目，然后在主机字段中输入 Tomcat 服务器的 IP 地址。您可以保留其他字段的默认值。然后单击底部的调试，Eclipse 调试器应连接到 Tomcat。
