I configured Elastic APM agent using Elastic manual: [Set up the Agent | APM PHP Agent Reference [1.x] | Elastic](https://www.elastic.co/guide/en/apm/agent/php/current/setup.html)

I configured PHP 7.4 to use elastic\_apm.so and restarted PHP-FPM. It fails on every start/connectoin:

```auto
-- A start job for unit php-7.4-fpm.service has finished successfully.
-- 
-- The job identifier is 420341.

Hi Aleksey,

Is it possible that the user under which application is running doesn't have permissions to access ` /root/eapmsrc/`? If you would like to make sure that is the root cause I've added diagnostics for the agent to log when `php_stream_open_for_zend_ex` fails. Then changes are already merged to the main branch but it's not released yet but you can use [the temporary binaries generated by CI](https://apm-ci.elastic.co/blue/organizations/jenkins/apm-agent-php%2Fapm-agent-php-mbp/detail/main/43/artifacts).

If the root causes is indeed the permissions I would advise to copy `/root/eapmsrc/` somewhere where any user has read access (don't forget to change `elastic_apm.bootstrap_php_part_file` configuration setting to point to the new location).

@Sergey_Kleyman thank you. It seems to be real cause. I moved files to web root and APM started work.
