在ubuntu 14.04中，向tomcat和移动第一服务器（worklight）添加权限的位置？

Question

我在Ubuntu 14.04上配置Mobile First Server v7.1。我在同一台机器上安装了tomcat。我不明白在哪里指定权限。是否需要将执行权限授予worklight服务器安装文件夹？

对于Apache Tomcat上，您必须执行以下措施的权利：

• 读取配置目录。
• 创建备份文件并修改配置目录中的文件，如server.xml和tomcatusers.xml
• 创建备份文件并修改bin目录中的文件，例如setenv.bat。
• 在lib目录下创建文件。
• 在webapps目录中创建文件。

其实，我得到以下错误，所以我认为这可能是因为权限。

我不认为你需要给予任何特定的权限，除非你遇到任何特定的错误（你可以分享）。

一旦你安装了移动优先服务器，你可以使用服务器配置工具来首先配置移动设备，使用tomcat作为Web服务器。

的配置相同所需的步骤的细节可以在这里找到：https://www.ibm.com/support/knowledgecenter/en/SSHS8R_7.1.0/com.ibm.worklight.deploy.doc/deploy/c_using_server_config_tool.html
