介绍

WebVirtMgr是一个基于libvirt的Web界面，用于管理虚拟机。它允许您创建和配置新域，并调整域的资源分配。VNC查看器向来宾域显示一个完整的图形控制台。KVM是目前唯一支持的虚拟机管理程序。

技术：

应用程序逻辑是用Python和Django编写的。LIBVIRT Python绑定用于与底层虚拟机管理程序交互。

安装

1. 查看系统版本

[root@web ~]# hostnamectl 
   Static hostname: web.server.com
         Icon name: computer-desktop
           Chassis: desktop
        Machine ID: e57ef32020fa406d9bbee213aba339ed
           Boot ID: 5a70728f01fd4402a40d90d47e3f10df
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-1160.114.2.el7.x86_64
      Architecture: x86-64

2. 安装

]# yum -y install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release
]# yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor nginx gcc python-devel
 
]# pip3 install numpy 

3.安装python要求并设置Django环境

[root@web ~]# git clone https://github.com/retspen/webvirtmgr.git
[root@web ~]# cd webvirtmgr
[root@web webvirtmgr]# pip install -r requirements.txt

4.同步用户数据

[root@web webvirtmgr]# ./manage.py  syncdb
WARNING:root:No local_settings file found.
Creating tables ...
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_groups
Creating table auth_user_user_permissions
Creating table auth_user
Creating table django_content_type
Creating table django_session
Creating table django_site
Creating table servers_compute
Creating table instance_instance
Creating table create_flavor

You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Username (leave blank to use 'root'): root
Email address:                             
Password: 
Password (again): 
Superuser created successfully.
Installing custom SQL ...
Installing indexes ...
Installed 6 object(s) from 1 fixture(s)

5.添加一个超级用户

[root@web webvirtmgr]# ./manage.py  createsuperuser

Username: abbott
Email address: 
Password: 
Password (again): 
Superuser created successfully.

运行服务

[root@web webvirtmgr]# ./manage.py  runserver & 

默认端口："8000"

6.配置Nginx作为web代理

6.1 将项目文件拷贝到/var/www/

在/etc/nginx/conf.d添加文件webvirtmgr.conf:

[root@web webvirtmgr]# cp webvirtmgr /var/www/ -R

6.2 配置nginx代理

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 ~ .*\.(js|css)$ {
           proxy_pass http://127.0.0.1:8000;
    }

    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 
    }
}

6.3 检查nginx配置语法是否正确

[root@web nginx]# nginx -t 
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

6.4 启动nginx

[root@web nginx]# systemctl  start nginx
[root@web nginx]# systemctl enable nginx
