关于linux:KVM-WEB管理工具-WebVirtMgr

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-releaseCentOS Linux release 7.9.2009 (Core)

内核版本

[root@webc ~]# uname -r3.10.0-1160.42.2.el7.x86_64

敞开Selinux & 防火墙

[root@webc ~]# systemctl stop firewalld[root@webc ~]# systemctl disable firewalld[root@webc ~]# setenforce 0setenforce: 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 -VPython 2.7.5[root@webc ~]#

查看KVM 驱动是否加载

[root@webc ~]# lsmod | grep kvmkvm_intel             188740  0kvm                   637515  1 kvm_intelirqbypass              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-br0DEVICE=br0TYPE=BridgeONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=staticIPADDR=192.168.1.49NETMASK=255.225.255.0GATEWAY=192.168.1.1DNS1=192.168.1.1[root@webc python-virtinst]# brctl showbridge name bridge id       STP enabled interfacesbr-0d093958d245     8000.0242d5824d14   no      br-2e2d3c481379     8000.0242884030e2   no      br-36a6ad3375a8     8000.0242d7d7f1ef   no      br-66a9675a6dd5     8000.024248a61c72   no      br-b7daf4844ff7     8000.024263dd4715   no      br-deba197eb09e     8000.0242b290e104   no      br0     8000.000000000000   no      docker0     8000.0242858c017c   no      vethe14f7acdocker_gwbridge     8000.0242588c6db0   no      virbr0      8000.5254009ba65a   yes     virbr0-nic[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'...remote: Enumerating objects: 5614, done.remote: Total 5614 (delta 0), reused 0 (delta 0), pack-reused 5614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]# lswebvirtmgr[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.confuser  root;worker_processes  1;events {    worker_connections  1024;}http {    include       mime.types;    default_type  application/octet-stream;    sendfile        on;    keepalive_timeout  65;    server {        listen       90;        server_name  192.168.1.104;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {            #root   html;            #index  index.html index.htm;            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 $remote_addr;            proxy_connect_timeout 600;            proxy_read_timeout 600;            proxy_send_timeout 600;            client_max_body_size 5120M;        }        location /static/ {            root /root/cby/kvm/webvirtmgr;            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 -tnginx: the configuration file /root/cby/kvm/nginx//conf/nginx.conf syntax is oknginx: 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.pydirectory=/root/cby/kvm/webvirtmgrautostart=trueautorestart=truelogfile=/var/log/supervisor/webvirtmgr.loglog_stderr=trueuser=root [program:webvirtmgr-console]command=/usr/bin/python /root/cby/kvm/webvirtmgr/console/webvirtmgr-consoledirectory=/root/cby/kvm/webvirtmgrautostart=trueautorestart=truestdout_logfile=/var/log/supervisor/webvirtmgr-console.logredirect_stderr=trueuser=rootEOF

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 statuswebvirtmgr                       RUNNING   pid 23783, uptime 0:00:11webvirtmgr-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
