Centos7安装KVM管理面板webvirtmgr-折腾笔记

物理环境：

一、安装

1、安装kvm Host Server

1 安装工具包

yum install qemu-kvm libvirt libvirt-python libguestfs-tools virt-install bridge-utils novnc -y
systemctl start libvirtd
systemctl enable libvirtd

1.1 安装libvirt 和KVM

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

或者

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

1.2 打开防火墙

sudo firewall-cmd --get-active-zones
sudo firewall-cmd --zone=public --add-port 16509/tcp --permanent
sudo firewall-cmd --reload

2、设置认知

可以采用SSH认知或者TCP认证，本次博主使用TCP认证

2、部署webvirtmgr

参考链接：https://github.com/retspen/webvirtmgr/wiki/Install-WebVirtMgr

2.1 安装依赖软件

$ sudo yum -y install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
$ sudo yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor nginx
$ sudo yum -y install gcc python-devel
$ sudo pip install numpy

2.1 下载WebVirtMgr

2.1.1 下载并初始化

$ git clone git://github.com/retspen/webvirtmgr.git
$ cd webvirtmgr
$ sudo pip install -r requirements.txt # or python-pip (RedHat, Fedora, CentOS, OpenSuse)
$ ./manage.py syncdb
$ ./manage.py collectstatic   #填写的用户名与密码用于Web登录

2.1.2 添加Supervisor

本次部署，博主不使用nginx代理，所以直接使用django服务器部署

webVirtMgr supervisor配置

[program:webvirtmgr]
command=/usr/bin/python  /home/webvirtmgr/manage.py runserver 0:80
directory=/home/webvirtmgr
user=root
autostart=true
autorestart=true
logfile=/var/log/supervisor/webvirtmgr.log
log_stderr=true

noVNC supervisor配置

[program:webvirtmgr-console]
command=/usr/bin/python /home/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

2.1.3 配置防火墙

sudo firewall-cmd --get-active-zones
sudo firewall-cmd --zone=public --add-port 80/tcp --permanent
sudo firewall-cmd --zone=public --add-port 6080/tcp --permanent
sudo firewall-cmd --zone=public --add-port 16509/tcp --permanent
sudo firewall-cmd --reload

三、网络配置

3.1 物理机桥接网卡配置

3.1.1 复制物理机网卡配置文件

进入网卡配置文件目录

/etc/sysconfig/network-scripts

复制原物理机网卡到ifcfg-br0

cp ifcfg-em1 ifcfg-br0

编辑ifcfg-br0内容如下：

TYPE="Bridge"
BOOTPROTO="static"
IPADDR=192.168.2.10
GATEWAY=192.168.2.1
NETMASK=255.255.255.0
DNS1=192.168.1.1
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
NAME="br0"
DEVICE="br0"
ONBOOT="yes"

编辑原物理机网卡ifcfg-em1

NAME="em1"
DEVICE="em1"
ONBOOT="yes"
BRIDGE="br0"

重启网卡

systemctl restart network

网卡配置如下ip addr:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master br0 state UP qlen 1000
    link/ether 00:26:b9:49:4c:73 brd ff:ff:ff:ff:ff:ff
3: em2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000
    link/ether 00:26:b9:49:4c:75 brd ff:ff:ff:ff:ff:ff
4: em3: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000
    link/ether 00:26:b9:49:4c:77 brd ff:ff:ff:ff:ff:ff
5: em4: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000
    link/ether 00:26:b9:49:4c:79 brd ff:ff:ff:ff:ff:ff
6: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 
    link/ether 00:26:b9:49:4c:73 brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.10/24 brd 192.168.2.255 scope global br0
       valid_lft forever preferred_lft forever
    inet6 fe80::d07f:c9ff:fe40:ee1d/64 scope link 
       valid_lft forever preferred_lft forever

2.1 配置webvirtMgr Networks

二、问题总结

1、qumu+tcp失败

执行virsh -c qemu+tcp://192.168.2.11/system nodeinfo时提示错误。

[root@localhost ~]# virsh -c qemu+tcp://192.168.1.1/system nodeinfo
error: failed to connect to the hypervisor
error: authentication failed: authentication failed

解决方法：暂时关闭权限认证，以后找到原因再解决。

编辑：vim /etc/libvirt/libvirtd.conf

listen_tls = 0
listen_tcp = 1
tcp_port = "16509"
listen_addr = "0.0.0.0"
auth_tcp = "none"

重启 libvirtd

systemctl libvirtd restart

隔断
