CentOS - Oct 2016 - I cannot add user to a group permanently

Hello Everyone,

I'm using a centos 7 server. I tried to add my own user to group
'apache'
and it works temporarily. When I ssh to it later, I found my user not a
member of group 'apache'. What's wrong with it?
Thanks.

Sincerely,
Xuwen

Are you using "newgrp"?  That tool starts a new session wherein the
user
is a member of a new group.  Permanent addition should be "usermod -a -G 
$group $user"
