Bug 1270344

Description of problem:
selinux denies pmdaapache to gather apache statistics (the equivalent of running `curl http://localhost/server-status` ).

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-57

How reproducible:
Always

Steps to Reproduce:
1. enable extended apache statistics 
2. systemctl restart pmcd httpd
3. cd /var/lib/pcp/pmdas/apache
4. sudo ./Install

Actual results:
pmda is installed with warnings (and no stats values).  AVC denial is presented (output attached)


Expected results:
pmda should produce statistics from parsing http://localhost/server-status


Additional info:
SELinux is preventing /var/lib/pcp/pmdas/apache/pmdaapache from 'name_connect' accesses on the tcp_socket port 80.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow nis to enabled
Then you must tell SELinux about this by enabling the 'nis_enabled' boolean.
You can read 'None' man page for more details.
Do
setsebool -P nis_enabled 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that pmdaapache should be allowed name_connect access on the port 80 tcp_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pmdaapache /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
