openNebula 搭建
一、介绍
OpenNebula 是一款为云计算而打造的开源工具箱。它允许你和 Xen、KVM 或 VMware、ESX 一起建立和管理私有云, 同时还提供 Deltacloud 适配器与 Amazon EC2 相配合来管理混合云。
二、简单拓扑
三、安装
1、检查是否支持虚拟化:
grep -E ‘svm|vmx‘ /proc/cpuinfo
2、环境设置:
Frond-end:192.168.137.100
Node: 192.168.137.101
关闭防火墙:
# vi /etc/sysconfig/selinux
SELINUX=disabled
然后reboot
安装epel源:
yum install epel-release
设置yum源:
cat << EOT > /etc/yum.repos.d/opennebula.repo
[opennebula]
name=opennebula
baseurl=http://downloads.opennebula.org/repo/4.8/CentOS/7/x86_64/
enabled=1
gpgcheck=0
EOT
4、安装:
yum install opennebula-server opennebula-sunstone –y
运行 install_gems 安装所有依赖:
# /usr/share/one/install_gems
0. Ubuntu/Debian
1. CentOS/RedHat
2. SUSE
(选择服务器版本)
5、配置
修改OpenNebula守护进程ip:
vi /etc/one/sunstone-server.conf
将host: 127.0.0.1 改为host: 0.0.0.0
启动服务:
# service opennebula start
# service opennebula-sunstone start
6、设置nfs:
vi /etc/exports
添加:
/var/lib/one/ *(rw,sync,no_subtree_check,root_squash)
重启服务:
systemctl resatrt nfs
查看共享的挂载目录:
systemctl resatrt nfs
7、设置ssh证书认证(后面Frond-end部署kvm需要用ssh服务)
su oneadmin
$ cat << EOT > ~/.ssh/config
Host *
StrictHostKeyChecking no
UserKnownHostsFile /dev/null
EOT
$ chmod 600 ~/.ssh/config
四、node节点安装
yum install opennebula-node-kvm –y
# systemctl start messagebus.service
# systemctl start libvirtd.service
# systemctl start nfs.service
设置网络模式为桥接:
cd /etc/sysconfig/network-scripts
cp ifcfg-eth0 ifcfg-br0
vi ifcfg-eth0
TYPE=Ethernet
BOOTPROTO=none
NM_CONTROLLED=no
DEVICE=eth0
ONBOOT=yes
BRIDGE=br0
vi ifcfg-br0
DEVICE=br0
TYPE=Bridge
ONBOOT=yes
BOOTPROTO=static
NM_CONTROLLED=no
IPADDR=192.168.137.101
NETMASK=255.255.255.0
GATEWAY=192.168.137.1
重启服务:
systemctl restart network.service
挂载nfs:
vi /etc/fstab
192.168.1.1:/var/lib/one/ /var/lib/one/ nfs soft,intr,rsize=8192,wsize=8192,noauto
mount –a
df –Th(查看)
