CentOS7 Install Instructions

I recently installed webvirtcloud on CentOS7 bare metal and ran into some issues and misconfigurations that are not documented so I thought I'd share with the community.

---

Install software

There are some packages you need to install a bit different (well, different names) than ubuntu.

Note:

• This assumes you are working as root, but if you are not, make sure to "sudo" every command.

rpm installation

yum -y install python-virtualenv python-devel libxml2-dev libvirt-devel glibc gcc nginx supervisor git libxml2 libxml2-devel git

Creating directories and cloning repo

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

Start installation webvirtcloud

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

Configure the supervisor for CentOS

Add the following after the [include] line (after *files = ... * actually):

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:

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://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 $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:

chown -R nginx:nginx /srv/webvirtcloud

Add required user to the kvm group:

usermod -G kvm -a webvirtmgr

Install final required packages for libvirtd and others

wget -O - https://clck.ru/9V9fH | sudo sh

Please note this will not install gstfsd.ini correctly. You will need to download the file and install it manually:

curl https://raw.githubusercontent.com/retspen/webvirtcloud/master/conf/supervisor/gstfsd.conf > /etc/supervisord.d/gstfsd.ini

Let's restart nginx and the supervisord services:

systemctl restart nginx && systemctl restart supervisord

And finally, check everything is running:

supervisorctl status

gstfsd                           RUNNING    pid 24187, uptime 2:59:14
novncd                           RUNNING    pid 24186, uptime 2:59:14
webvirtcloud                     RUNNING    pid 24185, uptime 2:59:14

Done!!

Go to http://serverip and you should see the login screen.

This instructions almost worked for me.

Two notes:

• python-libguestfs was needed to get gstfsd running

# yum install python-libguestfs

• /srv/webvirtcloud must have httpd_sys_content_t context if SELinux is enabled

# semanage fcontext -a -t httpd_sys_content_t "/srv/webvirtcloud(/.*)"
# restorecon -Rv /srv/webvirtcloud
