I have some strange issue.
If I run haproxy as systemd service (version 1.8 from centos-scl-repository) I have issues running external healthchecks.
I get following error:
[ALERT] 022/162700 (23160) : Failed to exec process for external health check: Permission denied. Aborting.
When running the same from commandline it works as expected.
chroot is currently deactivated.
After a lot of trying I found out, that the issue is triggered by selinux. When I disable selinux with
setenforce 0 the error vanishes. If I reenable it, the error is there again.
I already executed the command setsebool -P haproxy_connect_any=1.
Thanks for any help
