CentOS 7.2下KVM虚拟化管理平台WebVirtMgr部署-服务器评测

WebVirtMgr采用几乎纯Python开发，其前端是基于Python的Django，后端是基于Libvirt的Python接口，将日常kvm的管理操作变的更加的可视化。

WebVirtMgr特点：
操作简单，易于使用
通过libvirt的API接口对kvm进行管理
提供对虚拟机生命周期管理
WebVirtMgr 功能

宿主机管理支持以下功能
CPU利用率
内存利用率
网络资源池管理
存储资源池管理

5、webvirtmgr配置
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 #启动8000端口
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 #启动6080端口（这是控制台vnc端口）
directory=/var/www/webvirtmgr
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/webvirtmgr-console.log
redirect_stderr=true
user=nginx

确保下面bind绑定的是本机的8000端口，这个在nginx配置中定义了，被代理的端口
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
注释掉39行
39 # listen 80 default_server;

systemctl restart nginx.service
systemctl start supervisord.service

后台执行
nohup /usr/bin/python2 /var/www/webvirtmgr/manage.py run_gunicorn -c /var/www/webvirtmgr/conf/gunicorn.conf.py &

6、KVM被管理端配置
vi /etc/sysconfig/libvirtd
LLIBVIRTD_CONFIG=/etc/libvirt/libvirtd.conf
LIBVIRTD_ARGS=”–listen”

vi /etc/libvirt/libvirtd.conf
listen_tls = 0
listen_tcp = 1
tcp_port = “16509”
listen_addr = “0.0.0.0”
auth_tcp = “none”
systemctl restart libvirtd.service
