安裝 Openstack-Quantum

1. 安裝 quantum 套件。
   

   [root@kvm4 ~(keystone_admin)]# yum install -y openstack-quantum openstack-quantum-openvswitch
   

2. Openstack Networking 服務必須連結 qpidd，先確認此服務正常運作。
   

   [root@kvm4 ~(keystone_admin)]# /etc/init.d/qpidd status
   qpidd (pid  17255) is running...
   

3. 設定 Openstack Networking。
   

   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   DEFAULT rpc_backend quantum.openstack.common.rpc.impl_qpid
   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   DEFAULT qpid_hostname 192.168.122.4
   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   DEFAULT qpid_username qpidauth
   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   DEFAULT qpid_password 123qwe
   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   DEFAULT qpid_protocol ssl
   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   keystone_authtoken admin_tenant_name services
   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   keystone_authtoken admin_user quantum
   [root@kvm4 ~(keystone_admin)]# openstack-config --set /etc/quantum/quantum.conf \
   keystone_authtoken admin_password 123qwe
   

4. 建立用戶 quantum 環境變數載入腳本。
   

   [root@kvm4 ~(keystone_admin)]# cat > keystonerc_quantum << EOF
   > if [ "\$1" == "" -o "\$1" == 'export' ];then
   >     export OS_USERNAME=quantum
   >     export OS_TENANT_NAME=services
   >     export OS_PASSWORD=123qwe
   >     export OS_AUTH_URL=http://kvm4.deyu.wang:35357/v2.0/
   >     export PS1='[\u@\h \W(keystone_quantum)]\\$ '
   > else
   >     unset OS_USERNAME
   >     unset OS_TENANT_NAME
   >     unset OS_PASSWORD
   >     unset OS_AUTH_URL
   >     export PS1='[\u@\h \W]\\$ '
   > fi
   > EOF
   

5. 變換環境變數為用戶 quantum。
   

   [root@kvm4 ~(keystone_admin)]# source keystonerc_quantum 
   [root@kvm4 ~(keystone_quantum)]#
   

6. 網路設定前一定要先確定本機的主機名稱及對應 ip。
   

   [root@kvm4 ~(keystone_quantum)]# hostname 
   kvm4.deyu.wang
   [root@kvm4 ~(keystone_quantum)]# host kvm4.deyu.wang
   kvm4.deyu.wang has address 192.168.122.4
   

7. Openstack Networking 設定會改變設定檔 /etc/nova/nova.conf，故先安裝包含此設定檔的套件 openstack-nova-common，其設定及使用請參考第 。
   

   [root@kvm4 ~(keystone_quantum)]# yum install -y openstack-nova-common
   

8. 設定 openstack networking 使用外掛 openvswitch。
   

   [root@kvm4 ~(keystone_quantum)]# quantum-server-setup --yes --rootpw 123qwe --plugin openvswitch
   Quantum plugin: openvswitch
   Plugin: openvswitch => Database: ovs_quantum
   Verified connectivity to MySQL.
   Configuration updates complete!
   

9. 啟動 quantum-server，並設定開機自動啟動。
   

   [root@kvm4 ~(keystone_quantum)]# /etc/init.d/quantum-server start
   Starting quantum-server:                           [  OK  ]
   [root@kvm4 ~(keystone_quantum)]# chkconfig quantum-server on
   

10. 查看啟動紀錄，是否有錯誤？沒有訊息表示正常。
    

    [root@kvm4 ~(keystone_quantum)]# egrep 'ERROR|CRITICAL' /var/log/quantum/server.log
    

11. 查看 openstack 狀況，注意 quantum，目前只有 quantum-server 啟動。
    

    [root@kvm4 ~(keystone_quantum)]# openstack-status 
    .....
    == Quantum services ==
    quantum-server:               active
    quantum-dhcp-agent:           inactive (disabled on boot)
    quantum-l3-agent:             inactive (disabled on boot)
    quantum-linuxbridge-agent:    dead (disabled on boot)
    quantum-openvswitch-agent:    inactive (disabled on boot)
    openvswitch:                  dead
    .....
