run.as 选项除了 Nifi 用户之外不起作用 [英] run.as option does not work other than Nifi user

问题描述

我想使用 ec2-user 而不是默认的 nifi 用户运行我的 NiFi 应用程序.我在 bootstrap.conf 中更改了 run.as=ec2-user 但它没有用.它不允许我启动 Nifi 应用程序在启动 nifi 服务时出现以下错误.

I want to run my NiFi application using ec2-user rather than default nifi user. I changed run.as=ec2-user in bootstrap.conf but it did not worked .It is not allowing me to start Nifi application getting following error while staring nifi service.

./nifi.sh start
nifi.sh: JAVA_HOME not set; results may vary

Java home:
NiFi home: /opt/nifi/current

Bootstrap Config File: /opt/nifi/current/conf/bootstrap.conf

User Runnug Nifi Application : sudo -u ec2-user
Error: Could not find or load main class org.apache.nifi.bootstrap.RunNiFi

有任何指向这个问题的指针吗?

Any pointer to this issue?

推荐答案

这很可能是文件权限问题，使用 nifi.sh install 安装服务不包括在内.所需权限的摘要包括:

This is most likely a file permission problem, which is not covered by installing the service with nifi.sh install. A summary of the required permissions includes:

• 对 NIFI_HOME 目录中整个发行版的读取权限
• 对 NIFI_HOME 目录本身的写访问权限 - NiFi 将在运行时创建许多目录和文件，包括日志、工作、状态和各种存储库.
• 对bin目录的写访问
• 对conf目录的写访问
• 对 lib 目录和 lib 目录中的所有文件的写访问权限

• Read access to the entire distribution in the NIFI_HOME directory
• Write access to the NIFI_HOME directory itself - NiFi will create a number of directories and files at runtime including logs, work, state, and various repositories.
• Write access to the bin directory
• Write access to the conf directory
• Write access to the lib directory, and to all of the files in the lib directory

当然可以通过手动创建工作目录来缩小权限，并通过调整 NiFi 的设置来重新排列目录布局.但是上面的权限应该会让你开始.

It is certainly possible to narrow the permissions by creating the working directories manually, and by adjusting NiFi's settings to rearrange the directory layout. But the permissions above should get you started.
