Question

我很新来尝试apign并尝试探索它以查看是否可以像在内存数据网格中一样使用它。

我在ubuntu 64位（v 18.04）上安装了apache ignite，并按照ignite网站上的说明安装了debian软件包。所以运行良好。后来我得到了将ubuntu升级到19.04的通知。之后，每当我尝试运行点燃时：

 bin/ignite.sh config/default-config.xml

我收到此错误。

请记住，我不是linux的专业用户，这是我第一次使用ignite，因此是否缺少任何内容？

Answer 1

您使用什么配置？

对于打包的Ignite，您应该使用将ignite工作目录设置为/var/lib/apache-ignite的配置。

您应该使用类似于

的命令开始打包Apache Ignite。

sudo service apache-ignite@default-config.xml start

，而不是您的用户。

Answer 2

看起来像尝试启动点火的用户没有对工作目录的写入权限。只需设置正确的权限即可。您可以参考https://www.lifewire.com/uses-of-command-chmod-2201064之类的任何chmod指南来检查如何完成此操作。

将ubuntu升级到19.04后，无法运行apache ignite
