• OpenStack RDO部署vlan模式


    controll:eth0   192.168.2.211         comput:  etho   192.168.2.212

               eth1                                               eth1 

    1、网络设置

    controll

    eth0:

    # cat /etc/sysconfig/network-scripts/ifcfg-eth0
    DEVICE=eth0
    ONBOOT=yes
    HWADDR=00:E0:81:D8:43:BE
    TYPE=Ethernet
    BOOTPROTO=none
    IPADDR=192.168.2.211
    NETMASK=255.255.255.0
    GATEWAY=192.168.2.1
    DNS1=8.8.8.8
    View Code

    eth1:

    # cat /etc/sysconfig/network-scripts/ifcfg-eth1
    DEVICE=eth1
    TYPE=Ethernet
    ONBOOT=yes
    View Code

    comput

    eth0:

    # cat /etc/sysconfig/network-scripts/ifcfg-eth0
    DEVICE=eth0
    ONBOOT=yes
    HWADDR=00:E0:81:D8:43:BE
    TYPE=Ethernet
    BOOTPROTO=none
    IPADDR=192.168.2.212
    NETMASK=255.255.255.0
    GATEWAY=192.168.2.1
    DNS1=8.8.8.8
    View Code

    eth1:

    # cat /etc/sysconfig/network-scripts/ifcfg-eth1
    DEVICE=eth1
    TYPE=Ethernet
    ONBOOT=yes
    View Code

    2、更换源,更新系统

    进入到 /etc/yum.repos.d, 其中有个rhel-source.repo, 先改名为rhel-source.repo.bak,做个备份

    然后新建个 rhel-source.repo

    cd /etc/yum.repos.d
    mv rhel-source.reop rhel-source.reop.bak
    vi rhel-source.reop 

    内容如下:

    [base]
    name=CentOS-$releasever - Base
    baseurl=http://mirrors.163.com/centos/6.5/os/$basearch/
    gpgcheck=1
    gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
    #released updates
    [updates]
    name=CentOS-$releasever - Updates
    baseurl=http://mirrors.163.com/centos/6.5/updates/$basearch/
    gpgcheck=1
    gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
    #packages used/produced in the build but not released
    #[addons]
    #name=CentOS-$releasever - Addons
    #baseurl=http://mirrors.163.com/centos/6.5/addons/$basearch/
    #gpgcheck=1
    #gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
    #additional packages that may be useful
    [extras]
    name=CentOS-$releasever - Extras
    baseurl=http://mirrors.163.com/centos/6.5/extras/$basearch/
    gpgcheck=1
    gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
    #additional packages that extend functionality of existing packages
    [centosplus]
    name=CentOS-$releasever - Plus
    baseurl=http://mirrors.163.com/centos/6.5/centosplus/$basearch/
    gpgcheck=1
    enabled=0
    View Code

    更新系统

    yum update

    3、交换机设置

    需要把两台机器的eth1,设置成trunk.

    虚拟机的通讯,是通过eth1,虚拟机访问外部网络,是通过node10上的L3agent,br-ex到eth0上访问外部网络。

    交换机把虚拟机通讯的端口设置trunk模式,vlan的id是从1000到2000.

    4、开始安装

    安装packstack

    yum install -y http://rdo.fedorapeople.org/openstack/openstack-havana/rdo-release-havana.rpm
    yum install -y openstack-packstack

    创建一个应答文件

    packstack --gen-answer-file=multi-node.txt

    修改应答文件,由于我已经有专门的cinder volume, 所以不需要创建。如果你没有手工创建cinder volume,那么你就不修改就可以。

    CONFIG_CINDER_VOLUMES_CREATE=n
    CONFIG_HEAT_INSTALL=y
    CONFIG_NTP_SERVERS=0.uk.pool.ntp.org
    CONFIG_NAGIOS_INSTALL=y
    CONFIG_KEYSTONE_ADMIN_PW=admin    (登入密码)
    CONFIG_NOVA_COMPUTE_HOSTS=192.168.2.211,192.168.2.212   (控制,计算节点的IP)
    CONFIG_NEUTRON_OVS_TENANT_NETWORK_TYPE=vlan             (vlan模式)
    CONFIG_NEUTRON_OVS_VLAN_RANGES=physnet1:1000:2000       (虚拟机池)
    CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-eth1   
    CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-eth1:eth1
    CONFIG_HEAT_CLOUDWATCH_INSTALL=y
    CONFIG_HEAT_CFN_INSTALL=y
    CONFIG_NAGIOS_PW=nagios

    开始安装

    packstack --answer-file=multi-node.txt

    安装过程,有可能因为源的原因中断,你可以重复运行。

    如果遇到网络问题可以看下  /etc/resolv.conf

    vi /etc/resolv.conf

    5、完善

    装完后,由于目前RDO的问题,没有创建br-ex,需要我们手工来创建

    # cat /etc/sysconfig/network-scripts/ifcfg-br-ex 
    DEVICE=br-ex
    IPADDR=192.168.2.211
    PREFIX=24
    GATEWAY=192.168.2.1
    DNS1=8.8.8.8
    ONBOOT=yes

    修改 /etc/sysconfig/network-scripts/ifcfg-eth0,  注意:一定要加上eth0 的mac地址,不然会出错。

    # cat /etc/sysconfig/network-scripts/ifcfg-eth0
    DEVICE=eth0
    ONBOOT=yes
    HWADDR=00:E0:81:D8:43:BE

    然后运行下面命令

    ovs-vsctl add-port br-ex eth0; service network restart

    当运行 ovs-vsctl add-port的时候,网络就会中断,所以你两条命令需要一起执行。

    剩下的操作就是在Dashboard

    http://192.168.2.211 登陆Dashboard,密码你可以查看

    # cat /root/keystonerc_admin 
    export OS_USERNAME=admin
    export OS_TENANT_NAME=admin
    export OS_PASSWORD=admin
    export OS_AUTH_URL=http://172.28.1.10:35357/v2.0/
    export PS1='[u@h W(keystone_admin)]$
