为了构建 SDN 测试平台，我安装了 Vmware 工作站 14 pro 来运行 Mininet 和 OpenDayLight 控制器。因此，为了安装和运行 OpenDayLight，我遵循了一个教程。直到我尝试sudo ./distribution-karaf-0.4.0-Beryllium/bin/karaf从 vmware 终端内运行此命令时才出现问题。
它向我显示了以下消息：
karaf: JAVA_HOME not set; results may vary
./distribution-karaf-0.4.0-Beryllium/bin/karaf: 242: [:Illegal number:
OpenJDK 64-Bit Server VM warning: ignoring option Unsyncloadclass; support was removed in 11.0

Endorsed standards and standalone APIs in modular form will be supported via the concept of upgradeable modules.
Error: Could not create the java virtual machine.
Error: A fatal exception has occured. program will exit.
如何解决这个问题？
答案1
对于 opendaylight，您需要 openjdk-8，但您已安装 openjdk-11。这从 Ubuntu 运行 Opendaylight可能会帮助你
