Hi I am trying to install LimeSurvey 2.52 (latest) onto a Centos 7 VM.
I got stuck after setting permission to specific folders in my limesurvey directory.
whenever I try to navigate to https://10.100.100.22/limesurvey/ (10.100.100.22 being the vm's ip), i get this message:
/var/www/html/limesurvey/tmp/runtime should be writable by the webserver (766 or 776).
I found post with similar issue and that applying permission 777 would help.
so I change the ownership from root to apache and set permission to 777 with recursive to the /tmp directory
however I am still getting this message.
Anyone can help me with this?

Here are the permission setting within the limesurvey directory, if it helps.

Is this a fresh installation of CentOS7? Or did you already installed other PHP scripts without issues?
If there isn't a real permission issue it be SELinux.
Is SELinux on or off?

thanks Jelo. I change selinux to permissive, and it works now.

This worked for me:
