I am trying to implement something like an “LXC on CentOS 7 HowTo” for internal use. (Might as well get public afterwards.) I am following the HowTo for CentOS 6
(https://wiki.CentOS.org/HowTos/LXC-on-CentOS6). So, here’s what I did so far (Steps 1-6 can easily be omitted, but I am trying to be complete.)
1.) Disable delta RPM’s in /etc/yum.conf
2.) Remove LibreOffice
sudo yum remove “libreoffice*”
3.) System update
sudo yum -y update
4.) Install some niceties
sudo yum -y install emacs emacs-nox “@Development Tools” git subversion
6.) Install VirtualBox Guest Additions
7.) Install libvirt
sudo yum -y install libvirt libvirt-client libvirt-install
8.) Setting up root fs for a container:
sudo su –
mkdir -p /var/lib/libvirt/lxc/CentOS01/etc/yum.repos.d
cat cat /etc/yum.repos.d/CentOS-Base.repo | sed s/’$releasever’/7/g
yum groupinstall core –installroot=/var/lib/libvirt/lxc/CentOS01
# The following command seems to be redundant, as both packages are already installed as part of the core group.
yum -y install plymouth libselinux-python
Now, according to the old howto, I am to configure PAM in the new root fs. Reading through that; I don’t really understand what I am to do. For example, I am to replace a line with “session required pam_selinux.so close”. However, the matching line is a comment line, which makes me unsure.
Are those PAM configurations still required? If so, could someone help me on what to do exactly?
