TNS:permission denied : ORA-12546 in RHEL 8

Question

See more:

I created a DB connection test in PHP to connect to a remote oracle database. But it's throwing errors like

Failed to connect to Oracle
      Array ( [code] => 12546 [message] => ORA-12546: TNS:permission denied [offset] => 0 [sqltext] => )

PHP

$conn=oci_connect("ZZZZZ","zzzzz","zzzzzzzz");

If (!$conn)
    echo 'Failed to connect to Oracle';
 
else
    echo 'Succesfully connected with Oracle DB';
 $e = oci_error();   // For oci_connect errors pass no handle
 oci_close($conn);

What I have tried:

I gave 755 permission to oci8.so file but still it's not working.

Based on this: Oci8Exception ORA-12546: TNS:permission denied (Page 1) — User support — Remi's RPM repository - Forum[^]

Hi Remi!

After researching more, someone suggested this solution on stackoverflow:

Shell
# setsebool -P httpd_can_network_connect on
I haven't understood yet what it does but it worked for my case! He suggests that "this happens because the machine has SELinux activated, usually in the enforcing mode. I would not recommend to disable SELinux, but setting it to permissive looks to ease the process of identifying some problems with it. You can check SELinux status by sestatus."
