10. 在CentOS 6.3上通過源碼安裝Openstack Folsom之通過Glance上傳鏡像
11. 在CentOS 6.3上通過源碼安裝Openstack Folsom之通過Horizon啟動實例

系統(tǒng)環(huán)境

1. CentOS 6.3 x86_64
   
2. Openstack Folsom
   
3. 服務器IP：172.16.24.138
   
4. 注：因為用到了Quantum，系統(tǒng)需要至少兩塊網(wǎng)卡
   
5. 這里使用的flat+dhcp模式，類似于nova-network的flatmanager模式，所以網(wǎng)段最好跟物理機網(wǎng)段一致，后面會單獨發(fā)帖講解gre和local還有vlan模式

復制代碼

1. 修改/etc/nova/nova.conf，讓nova使用Quantum

1. sed -i 's/# network_api_class=nova.network.api.API/network_api_class=nova.network.quantumv2.api.API/g' /etc/nova/nova.conf
   
2. sed -i 's/# quantum_admin_username=<None>/quantum_admin_username=quantum/g' /etc/nova/nova.conf
   
3. sed -i 's/# quantum_admin_password=<None>/quantum_admin_password=service/g' /etc/nova/nova.conf
   
4. sed -i 's/# quantum_admin_tenant_name=<None>/quantum_admin_tenant_name=tenant/g' /etc/nova/nova.conf
   
5. sed -i 's/# quantum_url_timeout=30/quantum_url_timeout=30/g' /etc/nova/nova.conf
   
6. sed -i 's/# quantum_admin_auth_url=http:\/\/localhost:5000\/v2.0/quantum_admin_auth_url=http:\/\/localhost:5000\/v2.0/g' /etc/nova/nova.conf
   
7. sed -i 's/# quantum_auth_strategy=keystone/quantum_auth_strategy=keystone/g' /etc/nova/nova.conf
   
8. sed -i 's/# quantum_url=http:\/\/127.0.0.1:9696/quantum_url=http:\/\/127.0.0.1:9696/g' /etc/nova/nova.conf
   
9. sed -i 's/# libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtBridgeDriver/libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver/g' /etc/nova/nova.conf
   
10. sed -i 's/# linuxnet_interface_driver=nova.network.linux_net.LinuxBridgeInterfaceDriver/linuxnet_interface_driver=nova.network.linux_net.LinuxOVSInterfaceDriver/g' /etc/nova/nova.conf
    
11. sed -i 's/# linuxnet_ovs_integration_bridge=br-int/linuxnet_ovs_integration_bridge=br-int/g' /etc/nova/nova.conf
    
12. sed -i 's/# libvirt_ovs_bridge=br-int/libvirt_ovs_bridge=br-int/g' /etc/nova/nova.conf
    
13. sed -i 's/# libvirt_use_virtio_for_bridges=false/libvirt_use_virtio_for_bridges=True/g' /etc/nova/nova.conf

復制代碼

2. 修改/etc/libvirt/qemu.conf文件的如下一些選項

1. sed -i 's/#cgroup_device_acl = \[/cgroup_device_acl = \[/g' /etc/libvirt/qemu.conf
   
2. sed -i 's/#    "\/dev\/null", "\/dev\/full", "\/dev\/zero",/    "\/dev\/null", "\/dev\/full", "\/dev\/zero",/g' /etc/libvirt/qemu.conf
   
3. sed -i 's/#    "\/dev\/random", "\/dev\/urandom",/    "\/dev\/random", "\/dev\/urandom",/g' /etc/libvirt/qemu.conf
   
4. sed -i 's/#    "\/dev\/ptmx", "\/dev\/kvm", "\/dev\/kqemu",/    "\/dev\/ptmx", "\/dev\/kvm", "\/dev\/kqemu",/g' /etc/libvirt/qemu.conf
   
5. sed -i 's/#    "\/dev\/rtc", "\/dev\/hpet",/    "\/dev\/rtc", "\/dev\/hpet","\/dev\/net\/tun",/g' /etc/libvirt/qemu.conf
   
6. sed -i 's/#]/]/g' /etc/libvirt/qemu.conf

復制代碼

3. 設置/etc/hosts

1. echo "172.16.24.138 `hostname`" >>/etc/hosts

復制代碼

4. 啟動Nova相關服務

1. /etc/init.d/libvirtd restart
   
2. nova-api-os-compute --config-file=/etc/nova/nova.conf &
   
3. nova-api-metadata --config-file=/etc/nova/nova.conf &
   
4. nova-compute --config-file=/etc/nova/nova.conf &
   
5. nova-scheduler --config-file=/etc/nova/nova.conf &
