centos 版本 6.4,在centos库中已经提供了一个打包好的opennebula,目前版本是3.8.1
# cd /etc/yum.repos.d # curl -O http://dev.centos.org/centos/6/opennebula/opennebula-testing.repo
# yum repolist
前置机安装:opennebula-server opennebula-sunstone
节点安装:opennebula-node-kvm
我这里用了一台机器,既当前置机又做工作节点
yum install opennebula-server opennebula-sunstone opennebula-node-kvm
$brctl show
bridge name bridge id STPenabled interfaces
br0 8000.000000000000 no eth0

centos 6.4网桥设置失败报错如下:
原网卡eth0: Connection activation failed: Master connection not found or invalid
bridge网卡br0:Conncetion activation failed: Failed to determine connection’s virtual interface name
原因是NetworkManager接管网络造成的, 解决办法:
chkconfig NetworkManager off chkconfig –levels 35 network on /etc/init.d/NetworkManager stop /etc/init.d/network restart

如果你只用一个机器当前置机和节点,则可以省去此步骤
su - oneadmin ssh-keygen –t dsa cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
chmod600 ~/.ssh/authorized_keys
添加以下内容到 ~/.ssh/config
Host * StrictHostKeyChecking no UserKnownHostsFile /dev/null
复制 ~/.ssh 到所有工作节点:(只有一台机器就省略此部)
scp -r ~/.ssh node1: scp -r ~/.ssh node2: ...
用oneadmin测试ssh localhost是否成功
发现登录失败,我自己建了个用户,然后如此设置是可以登录localhost的,经过查证,原因是selinux开着的导致的,因为oneadmin的home在/var/lib/one下,没有在/home/下,因此被selinux拦截了,关闭selinux即可。这个官方文档没有说清楚,害我查了两天才弄清楚原因。
$ service opennebula start $service opennebula-sunstone start $service opennebula-occi start
http://10.1.81.224:9869/
cat /var/lib/one/.one/one_auth 看下登录名和密码
添加主机
$ onehost create localhost -i im_kvm -v vmm_kvm -n dummy
如果失败,则查看日志/var/log/one/oned.log
如果从其他IP登录此地址,需要修改sunstone的远程登录,修改etc/one/sunstone-server.conf为
:host: 0.0.0.0
即可。
可以从官网下载rpm包来安装,这个可以装比较新的版本
# yum install wget # wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm # rpm -ivh epel-release-6-8.noarch.rpm # yum update
下载页面为:http://downloads.opennebula.org/
选择下载4.2.0 CentOS 6 tarball
tar xvf CentOS-6-opennebula-4.2.0-1.tar.gz cd opennebula-4.2.0-1/ yum localinstall opennebula-common-4.2.0-1.x86_64.rpm yum localinstall opennebula-ruby-4.2.0-1.x86_64.rpm yum localinstall opennebula-4.2.0-1.x86_64.rpm yum localinstall opennebula-sunstone-4.2.0-1.x86_64.rpm yum localinstall opennebula-server-4.2.0-1.x86_64.rpm在计算节点上安装 kvm 和 opennebula-node-kvm:
yum install qemu-kvm qemu-kvm-tools libvirt yum localinstall opennebula-node-kvm-4.2.0-1.x86_64.rpm
/etc/init.d/libvirtd start 206 service opennebula start 207 chkconfig opennebula on 208 service opennebula-sunstone start 209 chkconfig opennebula-sunstone on打开浏览器,访问 http://10.1.81.224:9869 登陆界面,那登陆的用户名和密码是啥呢?用户名和密码在安装的时候已经随机生成,oneadmin 是用户名,后面的一串是密码
# cat /var/lib/one/.one/one_auth页面效果:
