我已经安装了Active MQ：
apt-get install activemq
ln -s /etc/activemq/instances-available/main /etc/activemq/instances-enabled/main
systemctl start activemq.service
然而，服务状态是活跃（退出）：
# systemctl status activemq.service
● activemq.service - Apache ActiveMQ
Loaded: loaded (/lib/systemd/system/activemq.service; disabled; vendor preset: enabled)
Active: active (exited) since Di 2017-11-21 13:06:41 CET; 21h ago
Nov 22 10:56:47 hostname systemd[1]: Started Apache ActiveMQ.
服务未运行：
# ps -ef | grep activemq
root 62776 41890 0 11:11 pts/1 00:00:00 grep --color=auto activemq
我没有找到任何错误消息来引导我继续前进。我没有找到activemq.service我猜测应该在某处的文件，但是如果没有文件，某些东西就会尝试启动：在我创建符号链接之前，我在这里遇到了一个错误，现在我已经创建了它，我不再收到错误。
我尝试 /etc/init.d/activemq使用一些进行编辑echo test > /tmp/test。但是，它/tmp/test没有被创建，似乎没有被执行。但是编辑文件会导致警告，Warning: activemq.service changed on disk. Run 'systemctl daemon-reload' to reload units.所以它似乎是启动过程的一部分。我在这里有点困惑。/lib/systemd/system/activemq.service存在。
我搜索了有关如何在 Xenial 上安装 ActiveMQ 的教程，但他们要么手动下载，要么除了命令之外没有提到任何其他内容apt-get。
/etc/init.d/activemq console main按照作品中的说明手动运行服务/usr/share/doc/activemq/README.Debian，因此安装本身似乎没有问题：

我不想手动安装它，因为我想在将来接收潜在的更新。我需要什么来运行提供的 ActiveMQ apt-get？
答案1
这是一个错误。我提交了一个错误报告。
