FcgidWrapper Permission Denied

Question

I am trying to setup FastCGI to work with PHP on Apache 2.4.6 (CentOS).

I am following the instructins verbatim from the docs: https://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html

/etc/httpd/conf/httpd.conf:

...
<Directory "/var/www/mybin">
    Options all
    Order allow,deny
    Allow from all
</Directory>
FcgidMaxRequestsPerProcess 10000
Alias /phpapp/ /var/www/myphpapp/
<Location "/phpapp/">
    Options +ExecCGI
    AddHandler fcgid-script .php
    FcgidWrapper /var/www/mybin/php-wrapper .php
    Order allow,deny
    Allow from all
</Location>
...

ls -al /var/www/{,mybin,myphpapp} (note the 0777 perms on everything relevant)

/var/www/:
total 4
drwxr-xr-x.  6 root root   68 Sep 18 20:51 .
drwxr-xr-x. 20 root root 4096 Sep 18 01:04 ..
drwxr-xr-x.  4 root root   32 Sep 18 15:02 html
drwxrwxrwx.  2 root root   24 Sep 18 20:35 mybin
drwxrwxrwx.  2 root root   18 Sep 18 20:20 myphpapp

/var/www/mybin:
total 4
drwxrwxrwx. 2 root root 24 Sep 18 20:35 .
drwxr-xr-x. 6 root root 68 Sep 18 20:51 ..
-rwxrwxrwx. 1 root root 23 Sep 18 20:01 php-wrapper

/var/www/myphpapp:

drwxrwxrwx. 2 root root 18 Sep 18 20:20 .
drwxr-xr-x. 6 root root 68 Sep 18 20:51 ..
-rwxrwxrwx. 1 root root 19 Sep 18 20:03 a.php

systemctl start httpd fails, so let's see what's wrong with systemctl -l status httpd:

● httpd.service - The Apache HTTP Server

Sep 18 20:53:46 localhost.localdomain systemd[1]: httpd.service failed.

It complains on line 264, which is the line with FcgidWrapper, saying Permission denied.

Where can I specify that Apache should be allowed to access my php-wrapper file?

Permission denied errors with CentOS and Apache httpd are very often SELinux related. — HBruijn, Sep 19 '16 at 21:08

I had the same issue and as HBruijn pointed out, Selinux was the issue.

I ran:

setenforce 0

Then I disabled it in the /etc/selinux/config:

SELINUX=disabled
