Amazon ec2 使用Systemd在EC2 Centos上运行Airflow Web服务器：权限被拒绝

我在EC2 CentOS中使用来管理用于启动进程的守护进程（即：Web服务器、工作进程和调度程序）。 当我运行

sudo systemctl启动气流web服务器时

: ec2-user : TTY=pts/0 ; PWD=/ ; USER=root ; COMMAND=/bin/systemctl enable airflow-webserver
Oct 30 01:27:37 ip-171-32-6-92.us-east-2.compute.internal sudo[11680]: ec2-user : TTY=pts/0 ; PWD=/ ; USER=root ; COMMAND=/bin/systemctl start airflow-webserver

Oct 30 01:27:37 ip-171-32-6-92.us-east-2.compute.internal systemd[1]: airflow-webserver.service failed

Web服务器服务

气流组和用户存在：

$ less /etc/group
# airflow:x:1001:ec2-user
$less etc/psswd
# ec2-user:x:1000:1000:EC2 Default User:/home/ec2-user:/bin/bash
# tss:x:59:59:Account used by the trousers package to sandbox the tcsd # daemon:/dev/null:/sbin/nologin
# airflow:x:1001:1001::/home/airflow:/bin/bash

没有帮助

更新

创建

aiffair

用户并在

usr/local/bin

下安装aiffair之后，将

ExecStart

更改为

usr/local/bin/aiffair-webserver--pid/run/aiffair/webserver.pid

I能够通过最初的拒绝权限。但是现在我得到了这个错误：

这是因为您试图以

airflow

用户身份运行，但

airflow

二进制文件的路径位于

/home/ec2 user/.local/bin/airflow

中，这是

ec2用户的主目录

将airflow安装到您的
airflow
用户有权访问的目录中。
我创建了一个airflow用户和组。通过该用户安装的气流随后运行systemd，但仍然出现以下错误“
