KVM 实践webvirtmgr 安装与配置

1. Installation
$ yum -y install http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm$ yum -y install git python-pip libvirt-python
libxml2-python python-websockify supervisor nginx
======================================================================================================
2. Install python requirements and setup Django environment
$ git clone git://github.com/retspen/webvirtmgr.git$ cd webvirtmgr$ pip install -r requirements.txt # or python-pip (RedHat,
Fedora, CentOS, OpenSuse)$ ./manage.py syncdb$ ./manage.py collectstatic
Adding additional superusers
$ ./manage.py createsuperuser
#这个是管理员账号，用上面的admin和这个管理员账号都可以登陆webvirtmgr的web界面管理平台

Setup Nginx

$ cd ..$ sudo mv webvirtmgr /var/www/ ( CentOS, RedHat, Fedora, Ubuntu )

[root@localhost webvirtmgr]# cd ..
[root@localhost ~]# mv webvirtmgr/ /var/www

Add file webvirtmgr.conf in /etc/nginx/conf.d:

[root@localhost ~]# vi /etc/nginx/conf.d/webvirtmgr.conf
server {
listen 80 default_server;

server_name $hostname;
#access_log /var/log/nginx/webvirtmgr_access_log;

注释掉default.conf

[root@localhost ~]# vi /etc/nginx/conf.d/default.conf
#
# The default server
#

#        location = /50x.html {
#    }
#
#}

Restart nginx service:

$ sudo service nginx restart

Update SELinux policy

/usr/sbin/setsebool httpd_can_network_connect true

make it permanet service: ( OpenSusE ,CentOS, RedHat, Fedora)

$ chkconfig supervisord on

4. Setup Supervisor

$ chown -R nginx:nginx /var/www/webvirtmgr

[root@localhost ~]# chown -R nginx:nginx /var/www/webvirtmgr
Create file /etc/supervisord.d/webvirtmgr.ini with following content:
[root@localhost ~]# mkdir /etc/supervisord.d
[root@localhost ~]# vi /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


重起服务

$ service supervisord stop$ service supervisord start

[root@localhost ~]# service supervisord stop
Stopping supervisord:                                      [FAILED]
[root@localhost ~]# service supervisord start
Starting supervisord:                                      [  OK  ]

5.1 Update 

$ cd /var/www/webvirtmgr$ git pull$ ./manage.py collectstatic$ service supervisord restart

启动服务

$ ./manage.py runserver 0:8000

用浏览器打开
HTTP://ip+:8000
下面开始设置客户端

我们现在设置用TCP方式连接客户端

客户端配置。

Setup libvirt and KVM

$ curl http://retspen.github.io/libvirt-bootstrap.sh | sudo sh

or if haven't curl

$ wget -O - http://retspen.github.io/libvirt-bootstrap.sh | sudo sh

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

验证是否安装成功

[root@localhost ~]# netstat -antp |grep 16509

Setup TCP Authorization

用saslpasswd2命令增加授权用户 我们现在增加一个xiaohai用户密码默认

$ saslpasswd2 -a libvirt fredPassword: xxxxxxAgain (for verification): xxxxxx

[root@localhost ~]# saslpasswd2 -a libvirt xiaohai
Password:
Again (for verification):

如果想查看所有用户可以用以下命令

$ sasldblistusers2 -f /etc/libvirt/passwd.dbfred@webvirtmgr.net: userPassword

[root@localhost ~]# sasldblistusers2 -f /etc/libvirt/passwd.db

xiaohai@localhost.localdomain: userPassword

如果想禁止用户访问可以用 -d

$saslpasswd2 -a libvirt -d fred

Verify settings 从服务端验证设置

[root@localhost www]# virsh -c qemu+tcp://10.1.4.13/system nodeinfo
Please enter your authentication name: xiaohai （用户名）
Please enter your password: （密码）

Try input login with domain (hostname):

$ sasldblistusers2 -f /etc/libvirt/passwd.dbfred@webvirtmgr.net: userPassword

现在遇到一个问题

就是我想远程连接桌面的时候 出现下面情况

Server disconnected (code: 1006)

解决方法

问题找了半天 才发现是一个python脚本没有执行成功 ./var/www/console/webvirtmgr-console
