系统环境：

[root@kvm-admin ~]# cat /etc/redhat-release

CentOS Linux release7.3.1611(Core)

关闭防火墙、selinux

[root@kvm-admin ~]# systemctl stop firewalld.service

[root@kvm-admin ~]# setenforce 0

一、安装部署WebVirtMgr

需要有repo源，centos7默认没有wget:yum install wget

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

1、安装依赖包

[root@localhost ~]# yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor nginx[root@localhost ~]# yum -y install gcc python-devel

[root@localhost ~]# pip install numpy

2、安装python需求并设置Django环境

2.1 输入用户信息:登录外部页面的管理用户

3、配置nginx

[root@localhost webvirtmgr]# cd ..

[root@localhost tools]#mkdir /var/www

[root@localhost tools]#mv webvirtmgr /var/www/

3.1 在/etc/nginx/conf.d目录下添加webvirtmgr.conf文件：

[root@localhost conf.d]# cd /etc/nginx/conf.d/

[root@localhost conf.d]# vim webvirtmgr.conf

server {

listen80default_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/{

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_timeout600;

proxy_read_timeout600;

proxy_send_timeout600;

client_max_body_size 1024M; # Set higher depending on your needs

}

}

3.2 编辑/etc/nginx/ngix.conf，注释server部分

vim /etc/nginx/nginx.conf

# server {

# listen80default_server;

# server_name localhost;

# root/usr/share/nginx/html;

#

# #charset koi8-r;

#

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

#

# # Load configuration filesforthe 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 {

# }

# }

3.3 修改属主属组，重启nginx

[root@localhost conf.d]# chown -R nginx:nginx /var/www/webvirtmgr

[root@localhost conf.d]# service nginx restart

4、创建/etc/supervisord.d/webvirtmgr.ini包含以下内容的文件：

[root@localhost conf.d]# vim /etc/supervisord.d/webvirtmgr.ini

[program:webvirtmgr]

command=/usr/bin/python /var/www/webvirtmgr/manage.py run_gunicorn -c /var/www/webvirtmgr/conf/gunicorn.conf.py

directory=/var/www/webvirtmgr

autostart=trueautorestart=truelogfile=/var/log/supervisor/webvirtmgr.log

log_stderr=trueuser=nginx

[program:webvirtmgr-console]

command=/usr/bin/python /var/www/webvirtmgr/console/webvirtmgr-console

directory=/var/www/webvirtmgr

autostart=trueautorestart=truestdout_logfile=/var/log/supervisor/webvirtmgr-console.log

redirect_stderr=trueuser=nginx

5、重新启动supervisor守护程序

[root@localhost conf.d]# service supervisord stop

[root@localhost conf.d]# service supervisord start

6、输入本机IP网页访问,用户名和密码是上面2.2设置的用户和密码。

二、配置KVM宿主机，下载并执行脚本：libvirt-bootstrap.sh，如果虚拟机比较多，该脚本执行时间会比较长

[root@localhost ~]# curl http://retspen.github.io/libvirt-bootstrap.sh | sudo sh

三、配置SSH连接

ssh和tcp设置一种即可，其实就是设置无密码登录，要注意的是从webvirtmgr的什么用户到宿主机的什么用户的无密码登录，比如我用nginx用户跑的django webvirtmgr，而宿主机是root跑的virsh，所以需要设置nginx到root的无密码登录。而git官网推荐的是用nginx用户跑django webvirtmgr，webvirtmgr用户跑的virsh，所以设置的是nginx用户到宿主机webvirtmgr用户的无密码登录。

创建SSH私钥和ssh配置选项(在安装了WebVirtMgr的系统上)：

[root@localhost conf.d]# sudo su - nginx -s /bin/bash-bash-4.2$ ssh-keygenGenerating public/private rsa key pair.

Enterfile in which to save the key (/var/lib/nginx/.ssh/id_rsa):

Created directory'/var/lib/nginx/.ssh'.

Enter passphrase (emptyforno passphrase):

Enter same passphrase again:

Your identification has been savedin /var/lib/nginx/.ssh/id_rsa.

Your public key has been savedin /var/lib/nginx/.ssh/id_rsa.pub.

The key fingerprint is:51:4d:c9:0b:24:99:10:45:9a:c5:6b:70:4c:85:e4:3b nginx@localhost.localdomain

The key's randomart image is:

+--[ RSA 2048]----+

| oXB*++.. |

| .=Bo. + |

| ooo. . . |

| oo . |

| .E |

| . |

| |

| |

| |

+-----------------+-bash-4.2$ touch ~/.ssh/config && echo -e "StrictHostKeyChecking=no\nUserKnownHostsFile=/dev/null" >> ~/.ssh/config-bash-4.2$ chmod 0600 ~/.ssh/config-bash-4.2$ cat .ssh/id_rsa.pub

KVM宿主机,将nginx用户公钥加到/root/.ssh/authorized_keys文件中。ssh秘钥连接成功后再网页添加KVM宿主机。
