# dnf -y install bash-completion

2.Disabling SELinux

First, disable selinux.　selinux is a feature that improves auditing and security in Linux, but when enabled, it can limit the behavior of services and the contents of the configuration considerably.
Therefore, it is basically a case of invalidation in many cases.

SELinux operating modes
Enforcing : SELinux functionality is enabled and access control is enabled
Permissive : SElinux will warn, but no access restrictions will be placed
disabled : Both SElinux function and access control are disabled]]></description>
