我已经在几台 Ubuntu18 机器上下载了 apache karaf 4.3.3。当我尝试通过客户端安装功能或运行任何命令时，我得到以下日志跟踪。当我在服务器上时，我能够运行客户端，但它通过脚本失败。

我正在使用的命令是

$KARAF_HOME/bin/start
$KARAF_HOME/bin/client -u karaf -p karaf "features:install myfeature"

有谁知道为什么会这样？和钥匙有关系吗？如果是这样，那么我应该改变什么？

我遇到了与返回“已关闭”状态的脚本类似的问题。

经过一些测试，我发现没有 TTY 时脚本会失败（如果您使用诸如 ansible 之类的工具就是这种情况）

您应该使用 karaf 客户端脚本中包含的“批处理模式”，因此您的命令将变为：

$KARAF_HOME/bin/client -u karaf -p karaf -b <<< "features:install myfeature"

以这种方式运行时，脚本不会要求 TTY，而是会从标准输入运行命令。在我的示例中，我使用“此处字符串”重定向到标准输入，但您当然可以使用任何您喜欢的重定向将命令传递到标准输入

如果您更喜欢从文件中读取命令，还有一个“-f”选项。详情见bin/client --help_

或者，如果您可以控制 ssh 命令，则可以在连接到远程计算机时使用 ssh 上的选项来强制分配 tty：

ssh -o RequestTTY=force my_server $KARAF_HOME/bin/client -u karaf -p karaf "features:install myfeature"

（见https://man7.org/linux/man-pages/man5/ssh_config.5.html）
