一、webvirtmgr 介绍及环境阐明
舒适提醒：装置 KVM 是须要 2 台都操作的，因为咱们是打算将 2 台都设置为宿主机所有都须要装置 KVM 相干组件

WebVirtMgr 是一个基于 libvirt 的 Web 界面，用于治理虚拟机。它容许您创立和配置新域，并调整域的资源分配。VNC 查看器为来宾域提供残缺的图形控制台。KVM 是目前惟一反对的虚拟机管理程序。
查看服务器版本号
[root@webc ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)内核版本
[root@webc ~]# uname -r
3.10.0-1160.42.2.el7.x86_64敞开 Selinux & 防火墙
[root@webc ~]# systemctl stop firewalld
[root@webc ~]# systemctl disable firewalld
[root@webc ~]# setenforce 0
setenforce: SELinux is disabled
[root@webc ~]# sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config更新软件包并装置 epel 扩大源
[root@webc ~]# yum update
[root@webc ~]# yum install epel*查看 python 版本
[root@webc ~]# python -V

[root@webc ~]#查看 KVM 驱动是否加载
[root@webc ~]# lsmod | grep kvm

kvm 637515 1 kvm_intel
irqbypass 13503 1 kvm
[root@webc ~]#
[root@webc ~]#
[root@webc ~]# modprobe -a kvm
[root@webc ~]# modprobe -a kvm_intel
[root@webc ~]#免密配置
[root@webc ~]# ssh-keygen
[root@webc ~]# ssh-copy-id -i .ssh/id_rsa.pub root@192.168.1.104二、装置 KVM
装置 KVM 依赖包及管理工具
kvm 属于内核态，不须要装置。然而须要一些治理工具包
[root@webc ~]# yum install qemu-img qemu-kvm qemu-kvm-tools virt-manager virt-viewer virt-v2v virt-top libvirt libvirt-Python libvirt-client python-virtinst bridge-utils tunctl
[root@webc ~]# yum install -y virt-install
[root@webc ~]#
[root@webc ~]# systemctl start libvirtd.service
[root@webc ~]# systemctl enable libvirtd.service
[root@webc ~]#
[root@webc ~]# cd cby/kvm/
[root@webc kvm]#
[root@webc kvm]#
[root@webc kvm]# git clone https://github.com/palli/python-virtinst.git
[root@webc kvm]# cd python-virtinst/
[root@webc python-virtinst]# python setup.py install
[root@webc python-virtinst]# virt-install
[root@webc python-virtinst]# yum install bridge-utils
[root@webc python-virtinst]#
[root@webc python-virtinst]# vim /etc/sysconfig/network-scripts/ifcfg-br0
[root@webc python-virtinst]#
[root@webc python-virtinst]#
[root@webc python-virtinst]#
[root@webc python-virtinst]#
[root@webc python-virtinst]#
[root@webc python-virtinst]# cat /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0

IPADDR=192.168.1.49
NETMASK=255.225.255.0

[root@webc python-virtinst]# brctl show

[root@webc python-virtinst]# ln -s /usr/libexec/qemu-kvm /usr/sbin/
三、WebVirtMgr 装置
装置 pip、git 及 supervisor && Nginx
WebVirtMgr 只在治理端装置
[root@webc ~]# yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor gcc python-devel
应用 pip 装置 Python 扩大程序库
[root@webc ~]# pip install numpy
git 克隆配置并运行 WebVirMgr
[root@webc ~]# cd cby/
[root@webc cby]# mkdir kvm
[root@webc cby]# cd kvm
[root@webc kvm]# pwd
/root/cby/kvm
[root@webc kvm]#
[root@webc kvm]# git clone git://github.com/retspen/webvirtmgr.git
正克隆到 'webvirtmgr'...

接管对象中: 100% (5614/5614), 2.97 MiB | 748.00 KiB/s, done.
解决 delta 中: 100% (3606/3606), done.
[root@webc kvm]#
[root@webc kvm]#
[root@webc kvm]# cd webvirtmgr
[root@webc webvirtmgr]# pip install -r requirements.txt# 初始化环境
[root@webc webvirtmgr]# ./manage.py syncdb
#配置 Django 动态页面
[root@webc webvirtmgr]# ./manage.py collectstatic启动 WebVirMgr
前台启动 WebVirMgr，默认是 Debug 模式同时日志打印在前台
用户名和明码是咱们刚刚创立的
下载 Nginx
[root@webc webvirtmgr]# cd ..
[root@webc kvm]# ls
webvirtmgr
[root@webc kvm]#
[root@webc kvm]# mkdir nginx
[root@webc kvm]# cd nginx
[root@webc nginx]# wget https://nginx.org/download/nginx-1.20.1.tar.gz
[root@webc nginx]# tar xf nginx-1.20.1.tar.gz
[root@webc nginx]# cd nginx-1.20.1/
[root@webc nginx-1.20.1]#批改 nginx 配置文件
[root@webc conf]# vim nginx.conf
[root@webc conf]#
[root@webc conf]# cat nginx.conf
user root;
worker_processes 1;
events {worker_connections 1024;}
http {

expires max;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {root html;}
}
}
[root@webc conf]#装置 Nginx
[root@webc nginx-1.20.1]# yum install -y gcc glibc gcc-c++ prce-devel openssl-devel pcre-devel
[root@webc nginx-1.20.1]# useradd -s /sbin/nologin nginx -M
[root@webc nginx-1.20.1]# ./configure --prefix=/root/cby/kvm/nginx/ --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module
[root@webc nginx-1.20.1]# make && make install启动 Nginx
[root@webc nginx-1.20.1]# cd /root/cby/kvm/nginx/sbin/
[root@webc sbin]# /root/cby/kvm/nginx/sbin/nginx -t
nginx: the configuration file /root/cby/kvm/nginx//conf/nginx.conf syntax is ok
nginx: configuration file /root/cby/kvm/nginx//conf/nginx.conf test is successful
[root@webc sbin]# /root/cby/kvm/nginx/sbin/nginx应用 systemctl 启停服务
[root@webc sbin]# cat > /etc/supervisord.d/webvirtmgr.ini << EOF
[program:webvirtmgr]
command=/usr/bin/python /root/cby/kvm/webvirtmgr/manage.py run_gunicorn -c /root/cby/kvm/webvirtmgr/conf/gunicorn.conf.py
directory=/root/cby/kvm/webvirtmgr
autostart=true
autorestart=true

log_stderr=true
user=root
[program:webvirtmgr-console]

directory=/root/cby/kvm/webvirtmgr
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/webvirtmgr-console.log
redirect_stderr=true
user=root
EOF启动 supervisor
[root@webc webvirtmgr]# systemctl daemon-reload
[root@webc webvirtmgr]# systemctl stop supervisord
[root@webc webvirtmgr]# systemctl start supervisord查看是否启动胜利
[root@webc webvirtmgr]# supervisorctl status
webvirtmgr RUNNING pid 23783, uptime 0:00:11
webvirtmgr-console RUNNING pid 23782, uptime 0:00:11
[root@webc webvirtmgr]#
四、Web 界面配置 webvirtmgr
4.1 增加主机设置存储
1.Add Connection 增加宿主机 (即 KVM 主机)
2. 点击 SSH 连贯
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. 点击增加
