ubuntu - 将 Play 应用程序部署为 Debian 包

Question

我在创建 Play 应用程序的 debian 发行版时遇到了一些问题。deb 文件已正确创建，我可以在 Ubuntu 15.04 上安装它，但无法安装启动和停止服务:

myusr@myhost:~/dev/projects/test/target$ sudo dpkg -i test_0.2_all.deb 
Selecting previously unselected package test.
(Reading database ... 350339 files and directories currently installed.)
Preparing to unpack test_0.2_all.deb ...
Unpacking test (0.2) ...
Setting up test (0.2) ...
Adding test to autostart using update-rc.d
update-rc.d: error: initscript does not exist: /etc/init.d/test
Failed to start test.service: Unit test.service failed to load: No such file or directory.
test could not be registered or started

我还尝试在包中包含 application.conf 的“生产版本”和一些 jvmopts，也不走运(deb 文件具有来自/conf 的 application.conf 版本，而不是来自 src/universal/conf - 是正确的路径？-，并且 jvmopts 似乎被完全忽略了)。

这是我在项目中使用的 build.sbt:

Answer 1

Failed to start test.service: Unit test.service failed to load: No such file or directory.

... 表明软件包生成器未运送或未正确安装 systemd单元文件或者它没有正确使用 sysvinit shim。你能运行以下命令吗:

dpkg -c test_0.2_all.deb 

sudo 不是必需的。这将列出 .deb 的文件内容。如果我们在这里看到一个 .service 文件，我们就必须查看包的 .postinst 文件，看看它是否在做任何愚蠢的事情(或者更像是缺少一些 initscript 设置节)。
