CentOS 7.2下KVM虛擬化管理平台WebVirtMgr部署

WebVirtMgr採用幾乎純Python開發，其前端是基於Python的Django，後端是基於Libvirt的Python介面，將日常kvm的管理操作變的更加的視覺化。

WebVirtMgr特點：
操作簡單，易於使用
通過libvirt的API介面對kvm進行管理
提供對虛擬機器生命週期管理
WebVirtMgr 功能

宿主機管理支援以下功能
CPU利用率
記憶體利用率
網路資源池管理
儲存資源池管理
虛擬機器映象
虛擬機器克隆
快照管理
紀錄檔管理
虛機遷移

虛擬機器管理支援以下功能
CPU利用率
記憶體利用率
光碟管理
關/開/暫停虛擬機器
安裝虛擬機器
VNC console連線
建立快照

系統環境：
CentOS Linux release 7.2.1511 (Core)

1、yum源的設定及安裝所需軟體包

yum -y install Git Python-pip libvirt-python libxml2-python python-websockify supervisor nginx
yum -y install gcc python-devel
pip install numpy   

2、下載webvirtmgr.git軟體
mkdir /application/
cd /application/
git clone git://github.com/retspen/webvirtmgr.git 
git clone https://github.com/retspen/webvirtmgr.git

wget http://www.sqlite.org/sqlite-3.5.6.tar.gz
cd sqlite-3.5.6/
./configure --disable-tcl 
make
make install

4、webvirtmgr安裝
cd /application/webvirtmgr
pip install -r requirements.txt

5、webvirtmgr設定
mkdir -pv /var/www
cp -Rv /application/webvirtmgr /var/www/webvirtmgr

vim /etc/nginx/conf.d/webvirtmgr.conf
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 $remote_addr;
proxy_connect_timeout 600;
proxy_read_timeout 600;
proxy_send_timeout 600;
client_max_body_size 1024M; # Set higher depending on your needs
}
}

chown -R nginx:nginx /var/www/webvirtmgr

vim /etc/supervisord.conf
[program:webvirtmgr]
command=/usr/bin/python2 /var/www/webvirtmgr/manage.py run_gunicorn -c /var/www/webvirtmgr/conf/gunicorn.conf.py                    #啟動8000埠
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/python2 /var/www/webvirtmgr/console/webvirtmgr-console                              #啟動6080埠（這是控制台vnc埠）
directory=/var/www/webvirtmgr
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/webvirtmgr-console.log
redirect_stderr=true
user=nginx

確保下面bind系結的是本機的8000埠，這個在nginx設定中定義了，被代理的埠
grep '^bind =' /var/www/webvirtmgr/conf/gunicorn.conf.py
bind = '127.0.0.1:8000'

systemctl restart nginx.service
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.
vi /etc/nginx/nginx.conf
注釋掉39行
39    #    listen      80 default_server;

systemctl restart nginx.service
systemctl start supervisord.service 

後台執行
nohup /usr/bin/python2 /var/www/webvirtmgr/manage.py run_gunicorn -c /var/www/webvirtmgr/conf/gunicorn.conf.py &
