Problem

Before installing SecureTransport you have to check whether the Linux Security-Enhanced Linux (SELinux) is disabled. On Oracle Linux and Red Hat Enterprise Linux SELINUX is enabled by default and will cause the installation/upgrade to fail.

Resolution

To check the status of the SELINUX execute the command below:

sestatus

When it is disabled the result should looks like:

SELinux status:                 disabled

When the SELINUX is enabled the output of the command would be:

SELinux status:                enabled

To disable SELINUX, you would have to edit the /etc/sysconfig/selinux file. For example:

 vi /etc/sysconfig/selinux

Set the parameter SELINUX to disabled:

SELINUX=disabled

Save the file and reboot the server.
