Arch Linux
Use webvirtmgr-git package from AUR
yaourt -S webvirtmgr-git
Then perform what you were told to do by post_install trigger. Do skip step 2.
2. Install python requirements and setup Django environment
Run:
$ git clone git://github.com/retspen/webvirtmgr.git $ cd webvirtmgr $ sudo pip install -r requirements.txt # or python-pip (RedHat, Fedora, CentOS, OpenSuse) $ ./manage.py syncdb $ ./manage.py collectstatic
Enter the user information:
You just installed Django's auth system, which means you don't have any superusers defined. Would you like to create one now? (yes/no): yes (Put: yes) Username (Leave blank to use 'admin'): admin (Put: your username or login) E-mail address: [email protected] (Put: your email) Password: xxxxxx (Put: your password) Password (again): xxxxxx (Put: confirm password) Superuser created successfully.
Adding additional superusers
Run:
$ ./manage.py createsuperuser
3. Setup Nginx
Warning: Usually WebVirtMgr is only available from localhost on port 8000. This step will make WebVirtMgr available to everybody on port 80. The webinterface is also unprotected (no https), which means that everybody in between you and the server (people on the same wifi, your local router, your provider, the servers provider, backbones etc.) can see your login credentials in clear text!
Instead you can also skip this step completely + uninstall nginx. By simply redirecting port 8000 to your local machine via SSH. This is much safer because WebVirtMgr is not available to the public any more and you can only access it over an encrypted connection.
Example:
$ ssh user@server:port -L localhost:8000:localhost:8000 -L localhost:6080:localhost:6080
You should be able to access WebVirtMgr by typing localhost:8000 in your browser after completing the install. Port 6080 is forwarded to make noVNC work.
If you really know what you are doing, feel free to ignore the warning and continue setting up the redirect with nginx:
$ cd .. $ sudo mv webvirtmgr /var/www/ ( CentOS, RedHat, Fedora, Ubuntu ) $ sudo mv webvirtmgr /srv/www/ ( OpenSuSe )
Add file webvirtmgr.conf in /etc/nginx/conf.d:
server {
listen 80 default_server;
server_name $hostname;
#access_log /var/log/nginx/webvirtmgr_access_log;
location /static/ {
root /var/www/webvirtmgr/webvirtmgr; # or /srv instead of /var
expires max;
}
location / {
proxy_pass http://127.0.0.1:8000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-for $proxy_add_x_forwarded_for;
proxy_set_header Host $host:$server_port;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_connect_timeout 600;
proxy_read_timeout 600;
proxy_send_timeout 600;
client_max_body_size 1024M; # Set higher depending on your needs
}
}Open nginx.conf out of /etc/nginx/nginx.conf (in Ubuntu 14.04 LTS the configuration is in /etc/nginx/sites-enabled/default):
$ sudo vim /etc/nginx/nginx.conf
Comment the Server Section as it is shown in the example:
# server {
# listen 80 default_server;
# server_name localhost;
# root /usr/share/nginx/html;
#
# #charset koi8-r;
#
# #access_log /var/log/nginx/host.access.log main;
#
# # Load configuration files for the default server block.
# include /etc/nginx/default.d/*.conf;
#
# location / {
# }
#
# # redirect server error pages to the static page /40x.html
# #
# error_page 404 /404.html;
# location = /40x.html {
# }
#
# # redirect server error pages to the static page /50x.html
# #
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# }
# }Restart nginx service:
$ sudo service nginx restart
Update SELinux policy
/usr/sbin/setsebool httpd_can_network_connect true
make it permanet service: ( OpenSusE ,CentOS, RedHat, Fedora)
$ sudo chkconfig supervisord on
4. Setup Supervisor
CentOS, RedHat, Fedora
Run:
$ sudo chown -R nginx:nginx /var/www/webvirtmgr
Create file /etc/supervisord.d/webvirtmgr.ini with following content:
[program:webvirtmgr] command=/usr/bin/python /var/www/webvirtmgr/manage.py run_gunicorn -c /var/www/webvirtmgr/conf/gunicorn.conf.py directory=/var/www/webvirtmgr autostart=true autorestart=true logfile=/var/log/supervisor/webvirtmgr.log log_stderr=true user=nginx [program:webvirtmgr-console] command=/usr/bin/python /var/www/webvirtmgr/console/webvirtmgr-console directory=/var/www/webvirtmgr autostart=true autorestart=true stdout_logfile=/var/log/supervisor/webvirtmgr-console.log redirect_stderr=true user=nginx
OpenSuSE
Run:
$ sudo chown -R nginx:nginx /srv/www/webvirtmgr
Add these lines to end of file /etc/supervisord.conf:
[program:webvirtmgr] command=/usr/bin/python /srv/www/webvirtmgr/manage.py run_gunicorn -c /srv/www/webvirtmgr/conf/gunicorn.conf.py directory=/srv/www/webvirtmgr autostart=true autorestart=true stdout_logfile=/var/log/supervisor/webvirtmgr.log redirect_stderr=true user=nginx [program:webvirtmgri-console] command=/usr/bin/python /srv/www/webvirtmgr/console/webvirtmgr-console directory=/var/www/webvirtmgr autostart=true autorestart=true stdout_logfile=/var/log/supervisor/webvirtmgr-console.log redirect_stderr=true user=nginx
Debian, Ubuntu
Run:
$ sudo service novnc stop $ sudo insserv -r novnc $ sudo vi /etc/insserv/overrides/novnc #!/bin/sh ### BEGIN INIT INFO # Provides: nova-novncproxy # Required-Start: $network $local_fs $remote_fs $syslog # Required-Stop: $remote_fs # Default-Start: # Default-Stop: # Short-Description: Nova NoVNC proxy # Description: Nova NoVNC proxy ### END INIT INFO $ sudo chown -R www-data:www-data /var/www/webvirtmgr
Add file webvirtmgr.conf in /etc/supervisor/conf.d:
[program:webvirtmgr] command=/usr/bin/python /var/www/webvirtmgr/manage.py run_gunicorn -c /var/www/webvirtmgr/conf/gunicorn.conf.py directory=/var/www/webvirtmgr autostart=true autorestart=true stdout_logfile=/var/log/supervisor/webvirtmgr.log redirect_stderr=true user=www-data [program:webvirtmgr-console] command=/usr/bin/python /var/www/webvirtmgr/console/webvirtmgr-console directory=/var/www/webvirtmgr autostart=true autorestart=true stdout_logfile=/var/log/supervisor/webvirtmgr-console.log redirect_stderr=true user=www-data
Restart supervisor daemon
Ubuntu, Debian
$ sudo service supervisor stop $ sudo service supervisor start
