### Warning!!!
How to update gstfsd daemon on hypervisor:
```bash
wget -O - https://clck.ru/9VMRH | sudo tee -a /usr/local/bin/gstfsd
sudo service supervisor restart
```
### Description
WebVirtCloud is a virtualization web interface for admins and users. It can delegate Virtual Machine's to users. A noVNC viewer presents a full graphical console to the guest domain. KVM is currently the only hypervisor supported.
### Generate secret key
You should generate SECRET_KEY after cloning repo. Then put it into webvirtcloud/settings.py.
```python
import random, string
haystack = string.ascii_letters + string.digits + string.punctuation
print(''.join([random.SystemRandom().choice(haystack) for _ in range(50)]))
```
### Install WebVirtCloud panel (Ubuntu)
```bash
sudo apt-get -y install git python-virtualenv python-dev python-lxml libvirt-dev zlib1g-dev nginx supervisor libsasl2-modules gcc pkg-config python-guestfs
git clone https://github.com/retspen/webvirtcloud
cd webvirtcloud
cp webvirtcloud/settings.py.template webvirtcloud/settings.py
# now put secret key to webvirtcloud/settings.py
sudo cp conf/supervisor/webvirtcloud.conf /etc/supervisor/conf.d
sudo cp conf/nginx/webvirtcloud.conf /etc/nginx/conf.d
cd ..
sudo mv webvirtcloud /srv
sudo chown -R www-data:www-data /srv/webvirtcloud
cd /srv/webvirtcloud
virtualenv venv
source venv/bin/activate
pip install -r conf/requirements.txt
python manage.py migrate
sudo chown -R www-data:www-data /srv/webvirtcloud
sudo rm /etc/nginx/sites-enabled/default
```
Restart services for running WebVirtCloud:
```bash
sudo service nginx restart
sudo service supervisor restart
```
Setup libvirt and KVM on server
```bash
wget -O - https://clck.ru/9V9fH | sudo sh
```
### Install WebVirtCloud panel (CentOS)
```bash
sudo yum -y install python-virtualenv python-devel libvirt-devel glibc gcc nginx supervisor python-lxml git python-libguestfs
```
#### Creating directories and cloning repo
```bash
sudo mkdir /srv && cd /srv
sudo git clone https://github.com/retspen/webvirtcloud && cd webvirtcloud
cp webvirtcloud/settings.py.template webvirtcloud/settings.py
# now put secret key to webvirtcloud/settings.py
```
#### Start installation webvirtcloud
```
sudo virtualenv venv
sudo source venv/bin/activate
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
```
#### Configure the supervisor for CentOS
Add the following after the [include] line (after **files = ... ** actually):
```bash
sudo vim /etc/supervisord.conf
[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
```
#### Edit the nginx.conf file
You will need to edit the main nginx.conf file as the one that comes from the rpm's will not work. Comment the following lines:
```
# 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 {
# }
# }
}
```
Also make sure file in **/etc/nginx/conf.d/webvirtcloud.conf** has the proper paths:
```
upstream gunicorn_server {
#server unix:/srv/webvirtcloud/venv/wvcloud.socket fail_timeout=0;
server 127.0.0.1:8000 fail_timeout=0;
}
server {
listen 80;
server_name servername.domain.com;
access_log /var/log/nginx/webvirtcloud-access_log;
location /static/ {
root /srv/webvirtcloud;
expires max;
}
location / {
proxy_pass http://gunicorn_server;
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 $remote_addr;
proxy_connect_timeout 600;
proxy_read_timeout 600;
proxy_send_timeout 600;
client_max_body_size 1024M;
}
}
```
Change permissions so nginx can read the webvirtcloud folder:
```bash
sudo chown -R nginx:nginx /srv/webvirtcloud
```
Change permission for selinux:
```bash
sudo semanage fcontext -a -t httpd_sys_content_t "/srv/webvirtcloud(/.*)"
```
Add required user to the kvm group:
```bash
sudo usermod -G kvm -a webvirtmgr
```
Let's restart nginx and the supervisord services:
```bash
sudo systemctl restart nginx && systemctl restart supervisord
```
And finally, check everything is running:
```bash
sudo supervisorctl status
gstfsd RUNNING pid 24662, uptime 6:01:40
novncd RUNNING pid 24661, uptime 6:01:40
webvirtcloud RUNNING pid 24660, uptime 6:01:40
```
#### Apache mod_wsgi configuration
```
WSGIDaemonProcess webvirtcloud threads=2 maximum-requests=1000 display-name=webvirtcloud
WSGIScriptAlias / /srv/webvirtcloud/webvirtcloud/wsgi_custom.py
```
#### Install final required packages for libvirtd and others on Host Server
```bash
wget -O - https://clck.ru/9V9fH | sudo sh
```
Done!!
Go to http://serverip and you should see the login screen.
### Default credentials
login: admin
password: admin
### Cloud-init
Currently supports only root ssh authorized keys and hostname. Example configuration of the cloud-init client follows.
```
datasource:
OpenStack:
metadata_urls: [ "http://webvirtcloud.domain.com/datasource" ]
```
### How To Update
