This guide shows the steps required for creating a complete deployment of the OpenCMT software for develpment and tests. 

Setup for CentOS

System setup

The basic requirement for the next recipe is working on a clean Virtual Machine with CentOS 7 operating system. These steps must be executed by root:

Be sure to have an updated version of the system, with the EPEL extension enabled

sudo yum -y install wget epel-release yum-plugin-priorities
sudo yum -y update

Install the CA certificate required by the internal software repositories

sudo wget -O /etc/yum.repos.d/EGI-trustanchors.repo http://repository.egi.eu/sw/production/cas/1/current/repo-files/EGI-trustanchors.repo
sudo yum -y install ca-policy-egi-core
sudo ln -s /etc/grid-security/certificates/USERTrustRSACertificationAuthority.pem /etc/pki/ca-trust/source/anchors/
sudo ln -s /etc/grid-security/certificates/GEANTeScienceSSLCA4.pem /etc/pki/ca-trust/source/anchors/
sudo wget -O /etc/pki/ca-trust/source/anchors/GEANT-OV-RSA-CA-4.pem https://pandora.infn.it/public/483fb5/dl/GEANT-OV-RSA-CA-4.pem
sudo update-ca-trust extract

Install the metadata for the internal software repositories (GEANT4, and CMT)

sudo wget -O /etc/yum.repos.d/root-el7.repo https://nexus.pd.infn.it/artifacts/repository/repo-files/root-el7.repo
sudo wget -O /etc/yum.repos.d/muotom-el7.repo https://nexus.pd.infn.it/artifacts/repository/muotom-repo-files/muotom-el7.repo

Install the tools and libraries required by the CMT software

sudo yum -y install git gcc-c++ make cmake3 doxygen geant4-vmc-mt-devel cmt-ulib-devel root-graf3d-eve xorg-x11-xauth mesa-dri-drivers

Since the GEANT4 package does not contain the particle data sets, download the required files from central repository

sudo geant4-dataset-download

VNC server setup

If it is necessary to install a VNC server on the virtual machine the steps required are the following:

 Install the graphic environment

sudo yum -y check-update
sudo yum -y groupinstall "X Window System"
sudo yum -y install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts
sudo unlink /etc/systemd/system/default.target
sudo ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target

Reboot the virtual machine

sudo reboot

Install the VNC server

sudo yum -y install tigervnc-server
sudo cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service

vncpasswd

Configure the VNC server (file $HOME/.vnc/config), this is a basic setup:

# securitytypes=vncauth,tlsvnc
# desktop=sandbox
geometry=1920x1080
# localhost
# alwaysshared
bs

Activate the service and the firewall setup

sudo systemctl daemon-reload
sudo systemctl enable vncserver@:1.service
sudo systemctl start vncserver@:1.service
sudo firewall-cmd --permanent --add-service vnc-server
sudo systemctl restart firewalld.service

Setup for CentOS 8 (Deprecated)

System setup

1. Be sure to have an updated version of the system, with the EPEL extension enabled 

   No Format
   sudo yum -y update sudo yum -y install epel-release yum-utils wget sudo yum-config-manager --set-enabled powertools sudo yum-config-manager --set-enabled appstream

   
   

2. Install the CA certificate required by the internal software repositories 

   No Format

   sudo wget -O /etc/yum.repos.d/EGI-trustanchors.repo http://repository.egi.eu/sw/production/cas/1/current/repo-files/EGI-trustanchors.repo sudo yum -y install ca-policy-egi-core sudo ln -s /etc/grid-security/certificates/USERTrustRSACertificationAuthority.pem /etc/pki/ca-trust/source/anchors/ sudo ln -s /etc/grid-security/certificates/GEANTeScienceSSLCA4.pem /etc/pki/ca-trust/source/anchors/ sudo wget -O /etc/pki/ca-trust/source/anchors/GEANT-OV-RSA-CA-4.pem https://pandora.infn.it/public/483fb5/dl/GEANT-OV-RSA-CA-4.pem sudo update-ca-trust extract

   
   

3. Install the metadata for the internal software repositories (GEANT4, and CMT) 

   No Format
   sudo wget -O /etc/yum.repos.d/root.repo https://nexus.pd.infn.it/artifacts/repository/repo-files/root-c17.repo sudo wget -O /etc/yum.repos.d/muotom.repo https://nexus.pd.infn.it/artifacts/repository/muotom-repo-files/muotom.repo

Storage setup

The data for tests are available via NFS, add this row to the file /etc/fstab

cld-storage-01.pd.infn.it:/data/brickOpenstack/muon-steel/sdb /mnt/muotom-data nfs defaults 0 0

then create the directory and mount the endpoint

sudo mkdir -p /mnt/muotom-data
sudo chmod a+rx /mnt/muotom-data
sudo mount -a
