Instructions for setting up warewulf development environment under KVM
|
|
|
|
1. Create Centos 7 development virtual machine under KVM
|
|
|
|
# KVM is running on server called master1 which is not my desktop
|
|
|
|
ssh -X master1
|
|
|
|
# On master1 server
|
|
|
|
wget -P /global/downloads/centos http://mirror.mobap.edu/centos/7.8.2003/isos/x86_64/CentOS-7-x86_64-Everything-2003.iso
|
|
|
|
qemu-img create -o preallocation=metadata -f qcow2 /global/images/centos-7.qcow2
|
|
|
|
# install wwdev Centos 7 development VM
|
|
|
|
sudo virt-install --virt-type kvm --name centos7-wwdev --ram 8192 \
|
|
--disk /global/images/centos-7.qcow2,format=qcow2 \
|
|
--network network=default \
|
|
--graphics vnc,listen=0.0.0.0 --noautoconsole \
|
|
--os-type=linux --os-variant=rhel7.0 \
|
|
--location=/global/downloads/centos/CentOS-7-x86_64-Everything-2003.iso
|
|
|
|
# Complete installation using virt-manager
|
|
|
|
# To start virt-manager on non-local server
|
|
|
|
ssh -X master1
|
|
|
|
sudo -E virt-manager
|
|
|
|
# Login to VM and install @development group and go language
|
|
|
|
ssh root@wwdev
|
|
|
|
# Disable selinux by modifying /etc/sysconfig/selinux
|
|
vi /etc/sysconfig/selinux
|
|
|
|
SELINUX=disabled
|
|
|
|
# disable firewall
|
|
|
|
systemctl stop firewalld
|
|
systemctl disable firewalld
|
|
|
|
|
|
|
|
2. Turn off default network dhcp on server master1
|
|
|
|
# shutdown all VMs
|
|
|
|
$ sudo virsh net-destroy default
|
|
|
|
$ sudo virsh net-edit default
|
|
|
|
# remove dhcp lines from XML
|
|
|
|
$ sudo virsh net-start default
|
|
|
|
|
|
3. Build and install warewulf on wwdev
|
|
|
|
ssh wwdev
|
|
|
|
|
|
# Fedora prerequisites
|
|
sudo dnf -y install tftp-server tftp
|
|
sudo dnf -y install dhcp
|
|
sudo dnf -y install ipmitool
|
|
sudo dnf install singularity
|
|
sudo dnf install gpgme-devel
|
|
sudo dnf install libassuan.x86_64 libassuan-devel.x86_64
|
|
|
|
# Centos prerequisites
|
|
sudo yum -y install tftp-server tftp
|
|
sudo yum -y install dhcp
|
|
sudo yum -y install ipmitool
|
|
sudo yum install http://repo.ctrliq.com/packages/rhel7/ctrl-release.rpm
|
|
sudo yum install singularityplus
|
|
sudo yum install gpgme-devel
|
|
sudo yum install libassuan.x86_64 libassuan-devel.x86_64
|
|
|
|
# follow README.md instructions
|
|
|
|
cd projects/ctrliq/warewulf
|
|
|
|
vi nodes.yaml.local
|
|
|
|
make -f Makefile.local install
|
|
|
|
# build VNFS
|
|
|
|
sudo singularity build --sandbox /global/chroots/centos-7 centos-7.def
|
|
|
|
vi /etc/warewulf/overlays/generic/etc/sysconfig/network-scripts/ifcfg-*
|
|
|
|
# add IP addresses
|
|
|
|
sudo ./wwbuild vnfs
|
|
|
|
sudo ./wwbuild kernel
|
|
|
|
sudo ../wwbuild overlay
|
|
|
|
sudo ./warewulfd
|
|
|
