🟢Ubuntu安装webvirtcloud

安装过程

检查先决条件

grep -E -c "vmx|svm" /proc/cpuinfo
apt-get install cpu-checker -y
kvm-ok

正常输出应为：

INFO: /dev/kvm exists
KVM acceleration can be used

安装KVM

apt-get install qemu-system qemu-kvm libvirt-daemon bridge-utils virt-manager virtinst -y
lsmod | grep -i kvm
systemctl status libvirtd

安装nginx

apt-get install git virtualenv python3-virtualenv python3-dev python3-lxml libvirt-dev zlib1g-dev libxslt1-dev nginx supervisor libsasl2-modules gcc pkg-config python3-guestfs libsasl2-dev libldap2-dev libssl-dev -y

安装webvirtcloud

从仓库中克隆最新的代码，并生成配置文件

git clone https://github.com/retspen/webvirtcloud
cd webvirtcloud
cp webvirtcloud/settings.py.template webvirtcloud/settings.py

生成一个密钥

openssl rand -base64 32
// 正常的输出为
sQoYzOEGM7X+D3Bw3DwLtDO/xP3j4u9ecdccm9Ihb4U=

编辑配置文件

nano webvirtcloud/settings.py
SECRET_KEY = "sQoYzOEGM7X+D3Bw3DwLtDO/xP3j4u9ecdccm9Ihb4U="

复制配置文件到系统配置

cp conf/supervisor/webvirtcloud.conf /etc/supervisor/conf.d
cp conf/nginx/webvirtcloud.conf /etc/nginx/conf.d

下载项目依赖并运行

cd ..
mv webvirtcloud /srv/
chown -R www-data:www-data /srv/webvirtcloud/
cd /srv/webvirtcloud/
virtualenv -p python3 venv
source venv/bin/activate
pip install -r conf/requirements.txt
python3 manage.py migrate
deactivate

运行Web服务

chown -R www-data:www-data /srv/webvirtcloud/
rm /etc/nginx/sites-enabled/default
systemctl restart nginx
systemctl restart supervisor
systemctl status nginx

配置KVM和Libvirt

wget -O - https://bit.ly/36baWUu | sh
adduser www-data kvm

Configuring Compute SSH connection

chown www-data -R ~www-data
sudo -u www-data ssh-keygen
cat > ~www-data/.ssh/config << EOF
Host *
StrictHostKeyChecking no
EOF
chown www-data -R ~www-data/.ssh/config

You need to upload webvirtcloud public key into authorized keys on the compute node.

For Local KVM Node:

cat /var/www/.ssh/id_ed25519.pub >>~/.ssh/authorized_keys

cat ~/.ssh/authorized_keys

For a remote compute node you can use ssh tool from the webvirtcloud server:

sudo -u www-data ssh-copy-id root@compute1

sudo -u www-data ssh-copy-id root@compute2

Test connection as nginx user:

$ sudo -u www-data ssh [email protected]

Warning: Permanently added '127.0.0.1' (ECDSA) to the list of known hosts.

Last login: Tue Jun 22 19:44:38 2021 from 127.0.0.1

[root@kvm-desktop ~]# exit

logout

Connection to 127.0.0.1 closed.

From the WebVirtCloud KVM Management web console navigate to Computes

Choose SSH connection method to add your KVM Nodes and input KVM node details — Name, IP/FQDN, Login username:

If all goes well the Status of the new node should show “Connected“

安装新虚拟机

1、存储池新建 storage 池

2、新建 iso 池（目录创建完成后先放入 iso 文件，然后再到页面上创建池）

# 创建目录（如果不存在）
sudo mkdir -p /var/lib/libvirt/images/iso_storage

# 设置权限
sudo chown -R libvirt-qemu:kvm /var/lib/libvirt/images/iso_storage
sudo chmod -R 755 /var/lib/libvirt/images/iso_storage
