Collect data in ITSI with SELinux

You may encounter these issues when you try to deploy collectd on a host that's running SELinux:

  • collectd's LogFile plug-in doesn't have persmissions to write to its log.
  • collectd can't establish a network connection and you see the CURL failed with status 7 error.

If you're running SELinux and want to deploy collectd, follow one of the following options so you don't encounter any failures.

Option 1:

Run the collectd process type in permissive mode:

semanage permissive -a collectd_t

SELinux won't deny access to collectd anymore, but you may still see the SELinux denial message.

Option 2:

  1. Fix the blocked network connection for collectd:
    setsebool -P collectd_tcp_network_connect 1
    
  2. Fix the permission denied for the LogFile plug-in. collectd's log is also available from syslog, and shouldn't require any changes to access from there. Use /var/log/collectd.log in collectd.conf for the LogFile plug-in.
  3. Create the mypolicy.te file with this content:
    module mypolicy 1.0;
    
    require {
    type var_log_t;
    type collectd_t;
    class dir { add_name read write };
    class file { create open write };
    }
    
    #============= collectd_t ==============
    
    allow collectd_t var_log_t:dir { add_name write };
    allow collectd_t var_log_t:file open;
    allow collectd_t var_log_t:file create;
    
  4. Compile mypolicy.te:
    $ checkmodule -M -m -o mypolicy.mod mypolicy.te
    $ semodule_package -o mypolicy.pp -m mypolicy.mod
    
  5. Apply the policy package mypolicy.pp to SELinux:
    $ semodule -i mypolicy.pp
