CentOS中Kvm可视化WebVirtMgr安装部署

温馨提示：安装KVM是需要2台都操作的，因为我们是打算将2台都设置为宿主机所有都需要安装KVM相关组件

github地址github.com/retspen/web…

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查看器为来宾域提供完整的图形控制台。KVM是目前唯一支持的虚拟机管理程序。

1.安装源和依赖

Centos/RHEL 6.X

1
2
yum -y install http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor nginx

Centos7

yum -y install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
 if this doesn't work, use yum install epel-release
yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor nginx
yum -y install gcc python-devel
pip install numpy

Debian 7, Ubuntu 12.04 and until ( excluding ) Ubuntu 20.04

1
apt-get install git python-pip python-libvirt python-libxml2 novnc supervisor nginx

Ubuntu 20.04 and above

1
apt-get install git python3-pip python3-libvirt python-libxml2 novnc supervisor nginx

2.克隆仓库并安装 Django 等 python 包

git clone https://github.com/retspen/webvirtmgr.git
cd webvirtmgr
# or python-pip (RedHat, Fedora, CentOS, OpenSuse)
pip install -r requirements.txt
# ( on Ubuntu 20.04 possible also : sudo apt install imagemagick )
# 初始化环境
. manage.py syncdb
# 配置Django 静态页面
. manage.py collectstatic

按提示输入 root 用户密码，该用户后面将用来登陆 WebVirtMgr。

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 (Put: yes)
Username (Leave blank to use 'admin'): admin (Put: your username or login)
E-mail address: username@domain.local (Put: your email)
Password: xxxxxx (Put: your password)
Password (again): xxxxxx (Put: confirm password)
Superuser created successfully.
1
./manage.py createsuperuser

然后测试：

1
./manage.py runserver 0:8000

用浏览器打开 http://your-ip:8000 并用刚才的用户登陆

然后点击右上角添加一个 Add connection，把 localhost 这个 libvirtd 的链接用 tcp 的方式添加进去，用户名和密码是刚才初始化的 libvirt 的管理员 admin 和密码，链接如果能够正常添加的话，表明可以正常运行了。

3.下载安装 Nginx

若已经安装nginx或rpm包之类的安装，直接设置nginx的配置文件即可

下载编译nginx

cd /usr/local/
mkdir nginx && cd nginx
wget https://nginx.org/download/nginx-1.20.1.tar.gz
tar xf nginx-1.20.1.tar.gz
cd nginx-1.20.1/
yum install -y gcc glibc gcc-c++ prce-devel openssl-devel pcre-devel
useradd -s /sbin/nologin nginx -M
./configure --prefix=/root/cby/kvm/nginx/ --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module
make && make install

设置nginx的配置文件

编辑webvirtmgr.conf到/etc/nginx/conf.d目录

server {
    listen 80 default_server;

    server_name $hostname;
    #access_log /var/log/nginx/webvirtmgr_access_log; 

    location /static/ {
        root /var/www/webvirtmgr/webvirtmgr; # 文件的路径
        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 
    }
}

如果nginx有默认的配置文件，需要注释掉默认的/etc/nginx/nginx.conf(Ubuntu 14.04 LTS配置文件夹在 /etc/nginx/sites-enabled/default)

1
vim /etc/nginx/nginx.conf

#        #charset koi8-r;

#        #access_log  /var/log/nginx/host.access.log  main;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        location / {
#        }
#
#        # redirect server error pages to the static page /40x.html
#        #
#        error_page  404              /404.html;
#        location = /40x.html {
#        }
#
#        # redirect server error pages to the static page /50x.html
#        #
#        error_page   500 502 503 504  /50x.html;
#        location = /50x.html {
#        }
#    }

2.点击SSH连接

3.Label 为主机名，必须为主机名做免密

4.IP 为宿主机IP

5.用户名为服务器用户名

6.点击添加

如下图 ,为添加kvm主机效果图:

安装完成
