1. Install dependencies:

   sudo yum install -y epel-release
   sudo yum -y install python-virtualenv python-devel libvirt-devel glibc gcc nginx supervisor libxml2 libxml2-devel git
   

2. Create working directory and clone repo into it:

   sudo mkdir -p /srv && cd /srv
   sudo git clone https://github.com/retspen/webvirtcloud && cd webvirtcloud
   

3. Edit 'conf/requirements.txt':

   • change libvirt-python to version, installed in your system (yum info libvirt-python, for now it's 3.2.0);
   • uncomment libxml2-python from retspen repo / comment gnome version.

4. Install webvirtcloud:

   sudo virtualenv venv
   sudo source venv/bin/activate
   sudo venv/bin/pip install --upgrade pip
   sudo venv/bin/pip install -r conf/requirements.txt
   sudo cp conf/nginx/webvirtcloud.conf /etc/nginx/conf.d/
   sudo venv/bin/python manage.py migrate
   

5. Edit '/etc/supervisord.conf': Add the following after the [include] line (after **files = ... ** actually):

   [program:webvirtcloud]
   command=/srv/webvirtcloud/venv/bin/gunicorn webvirtcloud.wsgi:application -c /srv/webvirtcloud/gunicorn.conf.py
   directory=/srv/webvirtcloud
   user=nginx
   autostart=true
   autorestart=true
   redirect_stderr=true
   
   [program:novncd]
   command=/srv/webvirtcloud/venv/bin/python /srv/webvirtcloud/console/novncd
   directory=/srv/webvirtcloud
   user=nginx
   autostart=true
   autorestart=true
   redirect_stderr=true
   

6. Edit the '/etc/nginx/nginx.conf': Comment out 'server' section:

   #    server {
   #        listen       80 default_server;
   #        listen       [::]:80 default_server;
   #        server_name  _;
   #        root         /usr/share/nginx/html;
   #
   #        # Load configuration files for the default server block.
   #        include /etc/nginx/default.d/*.conf;
   #
   #        location / {
   #        }
   #
   #        error_page 404 /404.html;
   #            location = /40x.html {
   #        }
   #
   #        error_page 500 502 503 504 /50x.html;
   #            location = /50x.html {
   #        }
   #    }
   

7. Change owner for working directory:

   sudo chown -R nginx:nginx /srv/webvirtcloud
   

8. Enable end start services:

   sudo systemctl enable nginx
   sudo systemctl enable supervisord
   sudo systemctl start nginx
   sudo systemctl start supervisord
   
   

9. SELinux. You can disable / switch to permissive mode or check 'denied' messaget in '/var/log/audit/audit.log' and create custom selinux modules:

   • check last message with

     cat /var/log/audit/audit.log | grep denied | tail -1
     

   • create and install module:

     cat /var/log/audit/audit.log | grep denied | tail -1 | audit2allow -M <MODULE_NAME> && semodule -i <MODULE_NAME>.pp
