系統環境：
[root@kvm-admin ~]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core) 關閉防火牆、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 Collecting numpy Downloading https://files.pythonhosted.org/packages/6a/a9/c01a2d5f7b045f508c8cefef3b079fe8c413d05498ca0ae877cffa230564/numpy-1.14.5-cp27-cp27mu-manylinux1_x86_64.whl (12.1MB) 100% |████████████████████████████████| 12.1MB 26kB/s Installing collected packages: numpy Successfully installed numpy-1.14.5 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需求並設置Django環境
[root@localhost ~]# cd /server/tools/ [root@localhost tools]# git clone git://github.com/retspen/webvirtmgr.git Cloning into 'webvirtmgr'... remote: Counting objects: 5730, done. remote: Compressing objects: 100% (6/6), done. remote: Total 5730 (delta 1), reused 0 (delta 0), pack-reused 5724 Receiving objects: 100% (5730/5730), 3.01 MiB | 341.00 KiB/s, done. Resolving deltas: 100% (3686/3686), done.
[root@localhost tools]# cd webvirtmgr/ [root@localhost webvirtmgr]# pip install -r requirements.txt Collecting django==1.5.5 (from -r requirements.txt (line 1)) Downloading https://files.pythonhosted.org/packages/38/49/93511c5d3367b6b21fc2995a0e53399721afc15e4cd6eb57be879ae13ad4/Django-1.5.5.tar.gz (8.1MB) 100% |████████████████████████████████| 8.1MB 42kB/s Collecting gunicorn==19.5.0 (from -r requirements.txt (line 2)) Downloading https://files.pythonhosted.org/packages/f9/4e/f4076a1a57fc1e75edc0828db365cfa9005f9f6b4a51b489ae39a91eb4be/gunicorn-19.5.0-py2.py3-none-any.whl (113kB) 100% |████████████████████████████████| 122kB 58kB/s Collecting lockfile>=0.9 (from -r requirements.txt (line 5)) Downloading https://files.pythonhosted.org/packages/c8/22/9460e311f340cb62d26a38c419b1381b8593b0bb6b5d1f056938b086d362/lockfile-0.12.2-py2.py3-none-any.whl Installing collected packages: django, gunicorn, lockfile Running setup.py install for django ... done Successfully installed django-1.5.5 gunicorn-19.5.0 lockfile-0.12.2 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.
2.1 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_settings file found. Creating tables ... Creating table auth_permission Creating table auth_group_permissions Creating table auth_group Creating table auth_user_groups Creating table auth_user_user_permissions Creating table auth_user Creating table django_content_type Creating table django_session Creating table django_site Creating table servers_compute Creating table instance_instance Creating table create_flavor You just installed Django's auth system, which means you don't have any superusers defined. Would you like to create one now? (yes/no): yes Username (leave blank to use 'root'): admin Email address: test@163.com Password: 123456 Password (again): 123456 Superuser created successfully. Installing custom SQL ... Installing indexes ... Installed 6 object(s) from 1 fixture(s)
2.2 生成配置文件
[root@localhost webvirtmgr]# ./manage.py collectstatic WARNING:root:No local_settings file found. You have requested to collect static files at the destination location as specified in your settings. This will overwrite existing files! Are you sure you want to do 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_settings file found. Username (leave blank to use 'root'): root Email address: test@163.com Password: 123456 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 { listen 80 default_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_timeout 600; proxy_read_timeout 600; proxy_send_timeout 600; 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 { # listen 80 default_server; # server_name localhost; # root /usr/share/nginx/html; # # #charset koi8-r; # # #access_log /var/log/nginx/host.access.log main; # # # Load configuration files for the 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=true autorestart=true logfile=/var/log/supervisor/webvirtmgr.log log_stderr=true user=nginx [program:webvirtmgr-console] command=/usr/bin/python /var/www/webvirtmgr/console/webvirtmgr-console directory=/var/www/webvirtmgr autostart=true autorestart=true stdout_logfile=/var/log/supervisor/webvirtmgr-console.log redirect_stderr=true user=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，下載並執行腳本：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-keygen Generating public/private rsa key pair. Enter file in which to save the key (/var/lib/nginx/.ssh/id_rsa): Created directory '/var/lib/nginx/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /var/lib/nginx/.ssh/id_rsa. Your public key has been saved in /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。
