我正在使用jdeb为基于debian的发行版生成我的.deb安装程序。应用程序安装没有错误,但是当我尝试运行service myapp start
时,它失败并出现以下异常(应用程序继续运行但FX场景永远不会显示):

同时,如果我只是运行sudo /etc/init.d/myapp start
,它就会运行而没有错误,并显示我的第一个FX场景。
Bellow是我对jdeb的maven配置:
<plugin>
<artifactId>jdeb</artifactId>
<groupId>org.vafer</groupId>
<version>1.5</version>
<executions>
<execution>
<id>appassembler</id>
<phase>package</phase>
<goals>
<goal>jdeb</goal>
</goals>
<configuration>
<deb>${project.build.directory}/${project.build.finalName}.deb</deb>
<snapshotExpand>false</snapshotExpand>
<!-- expand "SNAPSHOT" to what is in the "USER" env variable -->
<snapshotEnv>USER</snapshotEnv>
<verbose>true</verbose>
<controlDir>${basedir}/src/deb/control</controlDir>
<dataSet>
<data>
<src>${project.build.directory}/${project.build.finalName}-uber.jar</src>
<type>file</type>
<mapper>
<type>perm</type>
<prefix>/opt/stone/${project.build.finalName}</prefix>
<filemode>755</filemode>
<user>root</user>
<group>root</group>
</mapper>
</data>
<data>
<src>src/deb/upstart/${project.build.finalName}.conf</src>
<type>file</type>
<mapper>
<type>perm</type>
<prefix>/opt/stone/${project.build.finalName}</prefix>
<filemode>755</filemode>
<user>root</user>
<group>root</group>
</mapper>
</data>
</dataSet>
</configuration>
</execution>
</executions>
</plugin>
这是我的安装后脚本:
#!/bin/bash
echo Creating symblink...
sudo ln -s /opt/stone/acs/acs-uber.jar /etc/init.d/acs
echo Creating service...
sudo update-rc.d acs start 98 5 .
echo Starting service...
sudo service acs restart
答案 0 :(得分:1)
在Ubuntu上以javafx为根,从其他地方引用一个对我有用的答案...... 也许这可以帮助别人。我有同样的问题,但对于普通用户。让我们说我想使用用户帐户foo启动firefox。我以条形码登录:
[bar @ localhost~] $ sudo -u foo -H firefox
可悲的是,该命令失败并出现与问题相同的错误(即没有指定协议且无法打开显示)
我的解决方案是简单地将用户foo添加到授权访问X服务器的列表中。
xhost si:localuser:foo
就是这样,我可以使用sudo和用户foo启动Firefox(以及其他X应用程序)。
