mysqli_connect(): (HY000/2002): Permission denied [Fixed]
Today I’m going to share the solution of mysqli_connect(): (HY000/2002): Permission denied error. Let’s see:
Table of Contents
Reason
This error occurs for SELinux. Security-Enhanced Linux (SELinux) is a mandatory access control (MAC) security mechanism implemented in the kernel.
The httpd scripts by default are not allowed to connect out to the network. This would prevent a hacker from breaking into your httpd server and attacking other machines.
Solution
Apache/Nginx was not configured for external access. You need to enable the httpd_can_network_connect of SELinux. Run this command to check the state:
sudo getsebool -a | grep httpd_can_networkRun this command to enable httpd_can_network_connect on Apache/Nginx:
sudo setsebool -P httpd_can_network_connect 1Share on Social Media
