centos - 将 New Relic 与 Celery 集成

Question

我正在尝试将 New Relic 配置为与 Celery 一起使用。我正在开发一个托管在带有 CentOS 7 的 Amazon EC2 上的 Django 应用程序。
我认为为 celery 配置 New Relic 所需要做的就是在/etc/systemd/system/celery.service 中编辑以下行:ExecStart=/home/myuser/project/venv/bin/celery -A project worker -l info -c 4

并将其更改为:ExecStart=/home/myuser/project/newrelic.ini newrelic-admin run-program celery -A project worker -l info -c 4但我看到以下错误:

[root@ip-172-31-60-222 system]# systemctl daemon-reload
[root@ip-172-31-60-222 system]# systemctl restart celery
[root@ip-172-31-60-222 system]# systemctl status celery.service -l

我不确定我做错了什么。任何帮助是极大的赞赏!

你问这个问题已经有一段时间了，但失败的原因可能是错误的ExecStart命令。
您使用 /home/myuser/project/newrelic.ini newrelic-admin run-program celery -A project worker -l info -c 4作为启动服务的命令。命令的第一部分将尝试执行/home/myuser/project/newrelic.ini ，这是一个文本文件，失败并显示 Permission denied错误，因为文本文件默认没有 exec 权限。或者它会在某处导致 bash 语法错误并且也会失败。
Insead, 使用

Environment="NEW_RELIC_CONFIG_FILE=/home/myuser/project/newrelic.ini"
ExecStart=newrelic-admin run-program celery -A project worker -l info -c 4
