使用 docker 部署 kvm 图形化管理工具 WebVirtMgr

文章目录

kvm 官方提供了以下这些图形化管理，license 这块也提示了是商业版（Commercial）的还是哪个开源协议的，或者免费的范围

这边主要的需求就是有个 kvm 的图形化管理工具，通过浏览器就可以访问，机器不多，也不涉及私有云，这边就选择了 WebVirtMgr，能有简单的颜值，还有 vnc 模式访问虚拟机 - WebVirtMgr 是用 Python 和 Django 编写的，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的官网地址：http://retspen.github.io/- WebVirtMgr的 github 地址：https://github.com/retspen/webvirtmgr

前提条件

开始这篇文章的时候，默认已经部署了 kvm，如果没有部署，可以参考我之前的博客：CentOS 7 部署 KVM 虚拟化

以下的操作环境是 centos 7 这个发行版

镜像构建

官方最后一次更新已经是 2015年6月22日 了，官方也没有 docker 镜像，这边选择咱们自己构建

如果你的服务器有魔法，可以直接 git clone 一下 webvirtmgr 的包，没有的话，可以和我一样，提前从 github 上下载下来，上传到机器上，然后 ADD 到容器里面

这个项目已经很悠久了，只能用 2.x 的 python，这里就直接用 centos 作为基础镜像，对比过 debian 和 python 镜像，构建完都要1G多，用 centos 构建完只有 560MB

FROM docker.m.daocloud.io/centos:7.6.1810

ADD start.sh /start.sh
ADD webvirtmgr-4.8.9.tar.gz /

WORKDIR /webvirtmgr-4.8.9

# webvirtmgr 通过 tcp 连接 kvm 相关的依赖
RUN yum install -y cyrus-sasl cyrus-sasl-scram cyrus-sasl-devel cyrus-sasl-md5 && \
    yum clean all

CMD ["/usr/bin/bash","/start.sh"]

这里是 ADD 里面的启动脚本
start.sh
，本地记得
chmod +x start.sh
加个执行权限

fi

构建镜像

docker build -t webvirtmgr:4.8.9-centos-7.6 .

启动 webvirtmgr

启动参数仅供参考，里面有些配置是我本地环境相关的

如果 kvm 和 webvirtmgr 是相同机器，可以把 /var/run/libvirt/libvirt-sock 文件带入到容器内，就可以实现 local socket 的方式连接 kvm 宿主机了

docker run -d \
--restart=always \
--network host \
--memory 1024m \
--name webvirtmgr \
-v /var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock \
webvirtmgr:4.8.9-centos-7.6

创建其他 superuser

进入 webvirtmgr 容器

dockerexec-it webvirtmgr bash

创建其他超级用户

python manage.py createsuperuser

浏览器访问
IP:8000
看看能不能访问到 webvirtmgr 的页面

在这里插入图片描述

默认的用户名是
admin
，密码是
1qaz@WSX
，在启动脚本里面可以找到

在这里插入图片描述

配置 nginx 反向代理和域名访问

这一步不是必须的，有需求就做，这里也是用的 docker 容器的方式运行的，下面是需要打包到容器内的配置文件

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    # access_log  /var/log/nginx/access.log  main;

    # sendfile        on;
    # tcp_nopush     on;

    keepalive_timeout  65;
    gzip  on;

    server {
        listen       80;
        # 这里的域名，修改成自己的
        server_name  virtmgr.icu;
        # access_log /var/log/nginx/webvirtmgr_access_log;

        location / {
            proxy_pass http://192.168.18.222:8000;
            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;
            # 这里的配置，也可以再放大一点，这个会影响 iso 镜像的上传
            ## 如果直接放到指定的 iso 目录下，那就不受影响
            client_max_body_size 5120M;
        }

        location /static {
            proxy_pass http://192.168.18.222:8000/static;
        }
    }
}

下面是 Dockerfile

FROM docker.m.daocloud.io/nginx:1.26.0
ADD ./nginx.conf /etc/nginx/nginx.conf

构建镜像

docker build -t webvirtmgr-static:4.8.9-nginx-1.26.0 .

启动镜像

docker run -d--rm\-p80:80 \--memory 200m \--name webvirtmgr-static \
webvirtmgr-static:4.8.9-nginx-1.26.0

使用域名访问，域名没有 dns 解析的，可以本地自己配置一下 hosts

绑定 kvm 宿主机

local socket

在浏览器开始配置

在这里插入图片描述

绑定后，和主机通信成功的，就是绿色的，点击
192.168.18.222-local
就可以进去管理了

我本地用 virsh 创建过虚拟机，这里可以看到，也被展示出来了

在这里插入图片描述

tcp 连接

修改 kvm 配置，如果 kvm 已经有机器的，这个操作需要慎重考虑一下，或者有个环境能小规模模拟一下

/etc/libvirt/libvirtd.conf

# 修改 /etc/libvirt/libvirtd.conf 文件，把下面这些参数的注释打开
listen_tls =0
listen_tcp =1
tcp_port ="16509"
listen_addr ="0.0.0.0"
auth_tcp ="sasl"

/etc/sysconfig/libvirtd

# 修改 /etc/sysconfig/libvirtd  文件，把下面参数的注释打开LIBVIRTD_ARGS="--listen"

/etc/sasl2/libvirt.conf

# 修改 /etc/sasl2/libvirt.conf 文件，把下面参数的注释修改，注释掉之前打开的参数
mech_list: DIGEST-MD5
sasldb_path: /etc/libvirt/passwd.db

配置用户名密码，输入两次密码回车就可以了

saslpasswd2 -a libvirt virtadmin

验证授权文件

sasldblistusers2 -f /etc/libvirt/passwd.db

可以看到用户名和主机名

virtadmin@dream: userPassword

检查是否有
DIGEST-MD5
类型，没有该类型的话，执行 tcp 连接会有下面的报错：

error: failed to connect to the hypervisor

error: authentication failed: authentication failed

pluginviewer -c|grep-i'DIGEST-MD5'

如果没有返回的话，安装一下相关的插件

yum install-y cyrus-sasl cyrus-sasl-scram cyrus-sasl-devel cyrus-sasl-md5

重启 kvm

systemctl restart libvirtd

测试 tcp 连接

virsh-c qemu+tcp://dream/system list

提示输入用户名密码，然后能正常返回虚拟机列表

Please enter your authentication name: virtadmin
Please enter your password:
 Id    Name                           State

和上面的

虚拟机创建

虚拟机创建这块，还是 virt-manager 相对方便点，使用 webvirtmgr 创建虚拟机，需要先去存储池创建镜像（前提是，网络这些都创建好了，因为我的是之前使用过 kvm 创建，所以相关信息也都直接带入了，就只需要创建存储池的镜像就好了）

在这里插入图片描述

创建虚拟机

确认存储池创建了对应的镜像

New Instance 创建实例

Custom Instance 的方式创建

配置虚拟机名称，CPU，内存资源，选择提前创建的磁盘镜像和网络网卡，关闭主机模式，点击创建

在设置 -> media 里面找到需要使用的 iso 镜像，点击连接

在Power里面点击启动

在Access里面点击控制台
