kvm管理平台webvirtmgr的部署

git地址：https://github.com/retspen/webvirtmgr
环境：
system:centos6.2
libvirt: 0.10.2
webvirtmgr的安装，参考：https://github.com/retspen/webvirtmgr/wiki/Install-WebVirtMgr
1.安装虚拟化环境

yum -y groupinstall 'Virtualization Tools'
yum -y groupinstall 'Virtualization'
yum -y groupinstall 'Virtulization Client'
yum -y groupinstall 'Virtulization Platform'

2.安装依赖包

$ sudo yum -y install http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
$ sudo yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor nginx

3.克隆代码

$ git clone git://github.com/retspen/webvirtmgr.git
$ cd webvirtmgr
$ sudo pip install -r requirements.txt # or python-pip (RedHat, Fedora, CentOS, OpenSuse)

用pip安装django不太顺利，报错：
[root@vm03 ~]# pip install Django==1.5.5
Collecting Django==1.5.5
Could not find a version that satisfies the requirement Django==1.5.5 (from versions: 1.7plus-email-as-username-1.7.0, 4store-0.3, 503-0.1)
No matching distribution found for Django==1.5.5
折腾许久，只能去django官网下载了个Django-1.5.12.tar.gz包来安装

4.Django环境初始化
执行syncdb时，报错，未安装mysqldb
于是下载MySQL-python-1.2.5.zip，解压安装，又是一个报错：command ‘gcc’ failed with exit status 1
原因是未安装：mysql-devel，python-devel，mysql-python

$ ./manage.py syncdb
$ ./manage.py collectstatic

5.配置nginx
vim /etc/nginx/conf.d/webvirtmgr.conf 内容如下：

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 $scheme;
        proxy_connect_timeout 600;
        proxy_read_timeout 600;
        proxy_send_timeout 600;
        client_max_body_size 1024M; # Set higher depending on your needs 
    }
}

注释掉nginx的default内容，vim /etc/nginx/conf.d/default.conf 。然后启动nginx

 sudo service nginx restart

6.启动django

./manage.py runserver 0.0.0.0:8000

访问：http://x.x.x.x:8000 (x.x.x.x - your server IP address )，输入创建的django用户和密码，如果没有创建，请用python manager.py createsuperuser,命令创建。登录后如下图所示

webvirtmgr客户端就这样搭建完了，接下来需要配置虚拟机所在宿主机的，参考git地址：https://github.com/retspen/webvirtmgr/wiki/Setup-Host-Server

配置宿主机环境：
system: centos 6.6
libvirt: 0.10.2
1.下载并执行脚本：libvirt-bootstrap.sh
如果虚拟机比较多，该脚本执行时间会比较长，因为会执行service libvirt-guests restart，会将所有运行的虚拟机挂起然后再恢复，感觉这一步不是必须的，因为我有一台只设置ssh认证，也可以正常连接。

curl http://retspen.github.io/libvirt-bootstrap.sh | sudo sh

2.设置防火墙：

 sudo iptables -I INPUT -m state --state NEW -m tcp -p tcp --dport 16509 -j ACCEPT

3.设置TCP认证Setup TCP authorization
