系統環境：

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

CentOS Linux release7.3.1611(Core)

關閉防火墻、selinux

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

[root@kvm-admin ~]# setenforce 0

一、安裝部署WebVirtMgr

需要有repo源，centos7默認沒有wget:yum install wget

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

1、安裝依賴包

[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

You are using pip version 8.1.2, however version 18.0 is available.

You should consider upgrading via the 'pip install --upgrade pip' command.

2、安裝python需求并設置Django環境

[root@localhost ~]# cd /server/tools/[root@localhost tools]# git clone git://github.com/retspen/webvirtmgr.git

2.1 輸入用戶信息:登錄外部頁面的管理用戶

[root@localhost webvirtmgr]# ./manage.py syncdb

WARNING:root:No local_settingsfilefound.

2.2 生成配置文件

[root@localhost webvirtmgr]# ./manage.py collectstatic

WARNING:root:No local_settingsfilefound.

location as specifiedinyour settings.

This will overwrite existing files!Are you sure you want todo this?Type'yes' to continue, or 'no' to cancel:yes

2.3 也可以添加其他管理用戶

[root@localhost webvirtmgr]# ./manage.py createsuperuser

WARNING:root:No local_settingsfilefound.

Username (leave blank to use'root'): root

Email address: test@163.com

Password (again): 123456

Superuser created successfully.

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目錄下添加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 編輯/etc/nginx/ngix.conf，注釋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 修改屬主屬組，重啟nginx

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

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

4、創建/etc/supervisord.d/webvirtmgr.ini包含以下內容的文件：

[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、重新啟動supervisor守護程序

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

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

6、輸入本機IP網頁訪問,用戶名和密碼是上面2.2設置的用戶和密碼。

二、配置KVM宿主機，下載并執行腳本：libvirt-bootstrap.sh，如果虛擬機比較多，該腳本執行時間會比較長

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

三、配置SSH連接

ssh和tcp設置一種即可，其實就是設置無密碼登錄，要注意的是從webvirtmgr的什么用戶到宿主機的什么用戶的無密碼登錄，比如我用nginx用戶跑的django webvirtmgr，而宿主機是root跑的virsh，所以需要設置nginx到root的無密碼登錄。而git官網推薦的是用nginx用戶跑django webvirtmgr，webvirtmgr用戶跑的virsh，所以設置的是nginx用戶到宿主機webvirtmgr用戶的無密碼登錄。

創建SSH私鑰和ssh配置選項(在安裝了WebVirtMgr的系統上)：

[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宿主機,將nginx用戶公鑰加到/root/.ssh/authorized_keys文件中。ssh秘鑰連接成功后再網頁添加KVM宿主機。
