KVM安装+WebVirtMgr配置

安装环境：

一、KVM安装

linunx:CentOS Linux release 7.1.1503 (Core)

CPU   ：16核

内 存 ：48G

检查是否支持虚拟化：

[root@pri36 ~]# egrep "(vmx|svm)" /proc/cpuinfo

flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi

mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl

xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm

pcid dca sse4_1 sse4_2 popcnt aes lahf_lm ida arat epb dtherm tpr_shadow vnmi flexpriority ept vpid

安装KVM组件

[root@pri36 ~]# yum groupinstall -y "Virtualization" "Virtualization Client" "Virtualization Platform"

"Virtualization Tools"

检查kvm模块是否加载

[root@pri36 ~]# lsmod |grep kvm

kvm_intel             148081  0

kvm                   461126  1 kvm_intel

开启CPU的虚拟化支持

yum install policycoreutils-python

virsh pool-define-as kvm_p_w_picpaths dir - - - - "/home/kvm/p_w_picpaths"

virsh pool-define-as kvm_p_w_picpaths02 dir - - - - "/home/kvm/p_w_picpaths"

virsh pool-list --all

virsh pool-build kvm_p_w_picpaths02

virsh pool-start kvm_p_w_picpaths02

virsh pool-autostart kvm_p_w_picpaths02

virsh pool-info kvm_p_w_picpaths02

virsh vol-create-as kvm_p_w_picpaths2 guest2-rhel7.0.img 8G --formatqcow2

 yum install acpid -y

virsh vol-create-as kvm_p_w_picpaths02 centos_ceshi6.7.img 8G --format qcow2

virsh vol-list kvm_p_w_picpaths02

virt-install --connect qemu:///system -n centos_ceshi6.7 -r 512 -f /home/kvm/p_w_picpaths/centos_ceshi6.7.img -

s 8 --vnc --os-type=linux --os-variant=rhel6  --vcpus=1 --network bridge=br0 -c /home/CentOS-6.7-x86_64-

Gewara-SP2-bin.iso

virt-viewer centos_ceshi6.7

二、网卡绑定：

cd /etc/sysconfig/network-scripts/

cat > ifcfg-br0 << END

TYPE=Bridge

BOOTPROTO=none

DEVICE=br0

NAME=br0

NM_CONTROLLED=no

ONBOOT=yes

IPADDR=192.168.2.36

NETMASK=255.255.255.0

GATEWAY=192.168.2.11

DNS1=192.168.3.224

DNS2=202.96.209.5

END

cat > ifcfg-enp2s0 < END

TYPE=Ethernet

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

IPV6INIT=yes

IPV6_AUTOCONF=yes

IPV6_DEFROUTE=yes

IPV6_FAILURE_FATAL=no

NAME=enp2s0

UUID=157e14ff-4338-4849-9c2c-495d77b86357

HWADDR=f4:6d:04:16:e0:46

DEVICE=enp2s0

PREFIX=24

IPV6_PEERDNS=yes

IPV6_PEERROUTES=yes

BRIDGE=br0

systemctl stop ModemManager.service

yum remove ModemManager

systemctl start network.service

WebVirtMgr配置

1、配置epel源（已配置则忽略）

# cd /usr/local/src

# wget http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

# rpm –ivh epel-release-6-8.noarch.rpm

2、安装所需包

# yum -y install git python-pip libvirt-python libxml2-python python-websockify supervisor nginx

3、# vim /etc/sysconfig/libvirtd—去掉注释

    LIBVIRTD_ARGS="--listen"

4、# vim /etc/libvirt/libvirtd.conf—去掉注释

    listen_tls = 0

    listen_tcp = 1

    tls_port = "16514"

    tcp_port = "16509"

    listen_addr = "0.0.0.0"

    auth_tcp = "sasl"

#/etc/init.d/libvirtd restart

5、创建libvirt管理用户

# saslpasswd2 -a libvirt virtadmin       //添加实例账号

# sasldblistusers2 -f /etc/libvirt/passwd.db

    virtadmin@webvirt: userPassword

# saslpasswd2 -a libvirt -d virtadmin        //禁止virtadmin用户

6、WebVirtMgr安装及初始化配置

通过git克隆WebVirtMgr代码，并安装需要的Python组件

# cd /usr/local/src/

# git clone git://github.com/retspen/webvirtmgr.git

# cd webvirtmgr

# pip install -r requirements.txt

安装python-sqlite

# yum install python-sqlite2

对django进行环境配置

# ./manage.py syncdb          //设置账号密码邮箱，此账号可以登录webvirtmgr

#./manage.py collectstatic            //生成配置文件

#./manage.py createsuperuser             //添加管理员账号，此账号同样可以登录webvirtmgr

7、将WebVirtMgr复制到nginx网站根目录

# mkdir /var/www/

# cp -a /usr/local/src/webvirtmgr /var/www/

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

8、配置nginx

# vim /etc/nginx/conf.d/webvirtmgr.conf

add:

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 $remote_addr;

        proxy_connect_timeout 600;

        proxy_read_timeout 600;

        proxy_send_timeout 600;

        client_max_body_size 1024M; # Set higher depending on your needs

}

# mv /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf.bak

# /etc/init.d/nginx start

# chkconfig nginx on

9、配置supervisor

# vim /etc/supervisord.conf     //add in the end

[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

stdout_logfile=/var/log/supervisor/webvirtmgr-console.log

redirect_stderr=true

#/var/www/webvirtmgr/conf/gunicorn.conf.py

modify:

    bind = "0:8000"

# /etc/init.d/supervisord start

# chkconfig supervisord on

10、查看端口6080和8000是否已经启动

#netstat -ntlp | grep 6080

#netstat -ntlp | grep 8000

11、测试

# virsh -c qemu+tcp://127.0.0.1/system nodeinfo
