7. 在CentOS 6.3上通過源碼安裝Openstack Folsom之Nova使用Quantum
8. 在CentOS 6.3上通過源碼安裝Openstack Folsom之Novnc安裝
9. 在CentOS 6.3上通過源碼安裝Openstack Folsom之Horizon安裝
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(shí)例

錯誤修復(fù)
1. 刪除/etc/quantum/quantum.conf文件中添加的sed -i '14a log_dir = /var/log/quantum' /etc/quantum/quantum.conf
2. 刪除/etc/quantum/quantum.conf文件中添加的sed -i '15a log_file = quantum.log' /etc/quantum/quantum.conf
3.修正：
    net_id=`quantum net-create --tenant-id $put_id_of_project_one net_one --provider:network_type flat --provider:physical_network physnet1 |awk '/ id/ {print $4}'`
   為
   net_id=`quantum net-create --tenant-id $tenant_id net_one --provider:network_type flat --provider:physical_network physnet1 |awk '/ id/ {print $4}'`

4. 去除修改/etc/quantum/quantum.conf文件的如下一些選項(xiàng)中的：
    sed -i 's/# default_notification_level = INFO/default_notification_level = DEBUG/g' /etc/quantum/quantum.conf

系統(tǒng)環(huán)境

1. CentOS 6.3 x86_64
   
2. Openstack Folsom
   
3. 服務(wù)器IP：172.16.24.138
   
4. 注：因?yàn)橛玫搅薗uantum，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(jī)網(wǎng)段一致，后面會單獨(dú)發(fā)帖講解gre和local還有vlan模式
