Re: Error connecting to cassandra through php/browser
Temporarily disable SELinux (or set it to permissive mode) for troubleshooting is fine, but once you know SELinux is the cause, you should consider change the policies (often via setsebool or audit2allow) to allow the connection. Blindly disable SELinux does solve the issue, but it isn't a good security practice. On 11/04/2021 06:35, Shabu Khan wrote: Thank you Bowen. Much appreciated. You were right.

Re: Error connecting to cassandra through php/browser
What do you mean "through the browser"? Is it a php page that runs on something like Apache/Nginx? If that's the case, and the same code and the same setup works on Ubuntu 18 but not CentOS 7, I would recommend you to have a look at the SELinux logs.
