Mise à jours de MRIOutils¶

1- Méthode manuelle (déprécié)¶

mettre le site en maintenance

touch /opt/mri_outils/maintenance/maintenance.enable

Renommer l'ancien répertoire de l'appli:

mv /opt/mri_outils/www /opt/mri_outils/www.old

Créer nouveau repertoire et extraire nouvelle version

mkdir /opt/mri_outils/www
unzip -d /opt/mri_outils/www MRIOutils-version.zip

Copie de la config:

cp /opt/mri_outils/www.old/MRIOutils/settings_local.py /opt/mri_outils/www/MRIOutils/settings_local.py

Faire la maj du site, bdd et virtualenv:

source /opt/mri_outils/venv_MRIOutils/bin/activate
cd /opt/mri_outils/www/
pip install -r requirements.txt
./manage.py migrate
./manage.py collectstatic -c --noinput
./manage.py compilemessages
deactivate

Redémarrer apache et sortir de maintenance

service apache2 restart
rm /opt/mri_outils/maintenance/maintenance.enable

Quand la maj est déclaré ok supprimer la sauvegarde de l'ancienne version

2- Avec script update¶

copier le script ci dessous sur le serveur, puis l'executer en mettant en parametre le zip de la nouvelle version de MRIOutils.

#!/bin/bash

if [[ -z $1 ]]; then
    echo "Please provide the archive of the source code as the input of the script." 
    exit 1
fi

archive=$1

if [[ !(-e $archive) || !($(file --mime-type -b "$archive") == "application/zip") ]]; then
    echo "File $archive provided is not valid: provide a .zip file" 
    exit 1
fi

BACKUP_DIR="/opt/mri_outils/www.old" 
VENV_PATH="/opt/mri_outils/venv_MRIOutils"

# Maintenance mode
touch $MAINTENANCE_ENABLE_FILE

# Create backup
if [[ -e $BACKUP_DIR ]]; then
    read -p "A backup directory has been found. Do you want to delete it ? (type 'yes' if you want to delete it, otherwise the program will stop.) " must_delete_folder

    if [[ $must_delete_folder == "yes" ]]; then
        rm -rf $BACKUP_DIR
        if [[ !(-e $BACKUP_DIR) ]]; then
            echo "The previous backup directory '$BACKUP_DIR' has been deleted." 
        else
            echo "Warning: The current backup directory '$BACKUP_DIR' has not been deleted." 
            exit 0
        fi
    else
        echo "The current backup directory '$BACKUP_DIR' has been kept untouched." 
        exit 0
    fi
fi

mv $MRI_OUTILS_DIR $BACKUP_DIR
echo -e "\033[35mCreated new backup directory '$BACKUP_DIR'.\033[0m";

# Extract archive and add config files
echo "Extracting archive content..." 
mkdir $MRI_OUTILS_DIR
unzip -d $MRI_OUTILS_DIR $archive
cp "$BACKUP_DIR/MRIOutils/settings_local.py" "$MRI_OUTILS_DIR/MRIOutils/settings_local.py" 
echo -e "\033[35mDone.\033[0m" 

echo "Do upgrade..." 
source $VENV_PATH/bin/activate
cd $MRI_OUTILS_DIR
pip install -r requirements.txt
./manage.py migrate
./manage.py collectstatic -c --noinput
./manage.py compilemessages

echo "Restart apache..." 
service apache2 restart
echo -e "\033[35mDone.\033[0m" 

rm $MAINTENANCE_ENABLE_FILE

echo -e "\033[35mMRIOutils correctement mis à jours.\033[0m" 
echo "Pensez à effacer le repertoire $BACKUP_DIR quand celui-ci ne sera plus necessaire."
