After an investigation by one of my development guys, he found that the problem was that when migrating the applications to a new CentOS 7.5 Linux server, values were installed by default in the SELinux that did not allow the execution of functions of PHP through Apache for file management. I had never encountered problems with SELinux (Security Enhanced Linux) nor did I know it existed, the English league is: link
To edit the SELinux values we had to install a SELinux tool handler with:
[root@localhost ~]# yum install policycoreutils-python
Then execute a command to see which security policies were activated with the command:
[root@localhost ~]# semanage boolean -l | grep httpd
And start opening doors to different permits with:
[root@localhost ~]# setsebool -P httpd_permiso_a_activar 1
At the end of moving the flags taking reference to other Linux servers where we have a similar architecture, we have a configuration like this:
[root@localhost ~]# semanage boolean -l | grep httpd
