Overview

getenforce

If SELinux is enabled, the command will return "Enforcing".

yum provides /usr/sbin/semanage
yum provides sealert

yum -y install policycoreutils-python
yum -y install setroubleshoot-server

If you have a suspicion that SELinux may be at the root of your problems, run:

sealert -a /var/log/audit/audit.log

You may get an output similar to the following one, which helps diagnose the problem:

[...]
SELinux is preventing /usr/sbin/httpd from write access on the file manager.node.nodes.lock.
[...]

Then use audit2allow to parse the audit logs and generate the SELinux policy to allow a denied operation.

grep httpd /var/log/audit/audit.log | audit2allow

The result is similar to:

#============= httpd_t ==============
allow httpd_t httpd_log_t:file write;
