OpenStack Grizzly Multihost部署文档

生产环境中部署OpenStack基本的要求的是稳定，安全和可扩展性，使用Multihost方式部署的好处是保证了网络的高可用，服务器数量捉急，所以选择mseknibilel的部署方式会比较纠结于控制节点和网络节点的资源浪费。所以本文档参考Longgeek的这篇文章，只做控制节点和计算节点，1个控制节点配多个计算节点，Quantum部署在计算节点上。

环境要求

先安装1个控制节点和1个计算节点，计算节点可以动态增加，只要将IP地址递增即可

节点类型	网卡配置
控制节点	eth0 (172.16.0.51), eth1 (59.65.233.231)
计算节点	eth0 (172.16.0.52), eth1 (10.10.10.52), eth2 (59.65.233.233)

第一次搭建的时候出了些问题，网卡端口和网络配置没一一映射，通过Linux的mii-tool指令，可以查看每个端口的连接情况

控制节点

基本环境变量配置

export YS_CON_MANAGE_IP=172.16.0.51
export YS_CON_MANAGE_NETMASK=255.255.0.0
export YS_CON_EXT_IP=59.65.233.231
export YS_CON_EXT_NETMASK=255.255.255.0
export YS_CON_EXT_GATEWAY=59.65.233.254
export YS_CON_EXT_DNS=202.204.65.5
export YS_CON_SERVICE_ENDPOINT_IP=172.16.0.51
export YS_CON_MYSQL_USER=root
export YS_CON_MYSQL_PASS=123qwe
export ADMIN_PASSWORD=123qwe
export ADMIN_TOKEN=ceit
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=$ADMIN_PASSWORD
export OS_AUTH_URL="http://${YS_CON_MANAGE_IP}:5000/v2.0/"   
export OS_REGION_NAME=RegionOne
export SERVICE_TOKEN=${ADMIN_TOKEN}
export SERVICE_ENDPOINT=http://${YS_CON_MANAGE_IP}:35357/v2.0/

网络设置

设置网卡信息

cat > /etc/network/interfaces << _EOF_
auto eth0
iface eth0 inet static
address $YS_CON_MANAGE_IP
netmask $YS_CON_MANAGE_NETMASK

auto eth1
iface eth1 inet static
address $YS_CON_EXT_IP
netmask $YS_CON_EXT_NETMASK
gateway $YS_CON_EXT_GATEWAY
dns-nameservers $YS_CON_EXT_DNS
_EOF_

重启网络服务

/etc/init.d/networking restart

添加源

添加Ubuntu Grizzly源，并升级

cat > /etc/apt/sources.list.d/grizzly.list << _EOF_
deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main
deb  http://ubuntu-cloud.archive.canonical.com/ubuntu precise-proposed/grizzly main
_EOF_
apt-get update
apt-get -y upgrade --force-yes
apt-get install -y ubuntu-cloud-keyring --force-yes

安装MySQL和RabbitMQ

安装MySQL

export DEBIAN_FRONTEND=noninteractive
apt-get install -q -y mysql-server python-mysqldb
mysqladmin -u $YS_CON_MYSQL_USER password $YS_CON_MYSQL_PASS

修改/etc/mysql/my.cnf文件绑定地址从127.0.0.1到0.0.0.0，禁止 mysql 做域名解析，防止连接错误，然后重新启动mysql服务.

sed -i -e 's/127.0.0.1/0.0.0.0/g' -e '/skip-external-locking/a skip-name-resolve' /etc/mysql/my.cnf
/etc/init.d/mysql restart

安装 RabbitMQ

apt-get install -y rabbitmq-server --force-yes

时间同步NTP

安装NTP并配置以计算节点为同步时钟

apt-get install -y ntp
sed -i 's/server ntp.ubuntu.com/server ntp.ubuntu.com\nserver 127.127.1.0\nfudge 127.127.1.0 stratum 10/g' /etc/ntp.conf
service ntp restart

允许路由转发

开启路由转发

sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
sysctl net.ipv4.ip_forward=1

安装认证模块Keystone

apt-get install -y keystone --force-yes

增加数据库连接权限

mysql -u$YS_CON_MYSQL_USER -p$YS_CON_MYSQL_PASS -e "
create database keystone;
grant all on keystone.* to 'keystone'@'%' identified by 'keystone';"

修改/etc/keystone/keystone.conf配置文件

while read line;
do 
pattern=`echo $line | awk '{printf "%s %s",$1,$2}'`
sed -i "/$pattern/c $line" /etc/keystone/keystone.conf;
done << _EOF_
admin_token = $ADMIN_TOKEN
token_format = UUID
debug = True
verbose = True
connection = mysql://keystone:keystone@${YS_CON_MANAGE_IP}/keystone
_EOF_

启用keystone然后同步数据库

service keystone restart
keystone-manage db_sync

导入keystone数据，如果剪切板有限制的话最好分两次粘贴

重启网络服务

/etc/init.d/networking restart

添加源

添加Ubuntu Grizzly源，并升级

cat > /etc/apt/sources.list.d/grizzly.list << _EOF_
deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/grizzly main
deb  http://ubuntu-cloud.archive.canonical.com/ubuntu precise-proposed/grizzly main

apt-get update
apt-get -y upgrade --force-yes
apt-get install -y ubuntu-cloud-keyring

时间同步NTP

安装NTP并配置以计算节点为同步时钟

apt-get install -y ntp
sed -i 's/server ntp.ubuntu.com/server ${YS_CON_MANAGE_IP}/g' /etc/ntp.conf
service ntp restart

允许路由转发

开启路由转发

sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
sysctl net.ipv4.ip_forward=1

安装OpenVSwitch

安装OpenVSwitch，必须以下顺序

apt-get install -y openvswitch-datapath-source --force-yes
module-assistant auto-install openvswitch-datapath
apt-get install -y openvswitch-switch openvswitch-brcompat --force-yes

设置 ovs-brcompatd 启动：

sed -i 's/# BRCOMPAT=no/BRCOMPAT=yes/g' /etc/default/openvswitch-switch
echo 'brcompat' >> /etc/modules

启动 openvswitch-switch:

/etc/init.d/openvswitch-switch restart

再次启动,直到 ovs-brcompatd、ovs-vswitchd、ovsdb-server等服务都启动：

/etc/init.d/openvswitch-switch restart

直到检查出现：

lsmod | grep brcompat
    brcompat               13512  0 
    openvswitch            84038  7 brcompat

如果还是启动不了的话，用下面命令：

/etc/init.d/openvswitch-switch force-reload-kmod

创建网桥：

ovs-vsctl add-br br-int        # br-int 用于 vm 整合
ovs-vsctl add-br br-ex              # br-ex 用于从互联网上访问 vm
ovs-vsctl add-port br-ex eth2       # br-ex 桥接到 eth2

做完上面操作后，如果用ssh连接到eth2的话一定会断开，到机器上修改配置文件：

ifconfig eth2 0
ifconfig br-ex ${YS_COM_EXT_IP}/24
route add default gw ${YS_COM_EXT_GATEWAY} dev br-ex
echo "nameserver ${YS_COM_EXT_DNS}" > /etc/resolv.conf

cat > /etc/network/interfaces << _EOF_
auto eth0
iface eth0 inet static
address $YS_COM_MANAGE_IP
netmask $YS_COM_MANAGE_NETMASK

auto eth1
iface eth1 inet static
address $YS_COM_DATA_IP
netmask $YS_COM_DATA_NETMASK

auto eth2
iface eth2 inet manual
up ifconfig \$IFACE 0.0.0.0 up
up ip link set \$IFACE promisc on 
down ip link set \$IFACE promisc off
down ifconfig \$IFACE down

auto br-ex
iface br-ex inet static
address $YS_COM_EXT_IP
netmask $YS_COM_EXT_NETMASK
gateway $YS_COM_EXT_GATEWAY
dns-nameservers $YS_COM_EXT_DNS
_EOF_

重启网卡可能会出现：

/etc/init.d/networking restart
RTNETLINK answers: File exists
Failed to bring up br-ex.

br-ex 可能有 ip 地址，但没有网关和 DNS，需要手工配置一下，或者重启机器. 重启机器后就正常了

文档更新：发现网络节点的 eth2 网卡在系统重启后没有激活，写入到 rc.local中:

echo 'ifconfig eth2 up' >> /etc/rc.local

查看桥接的网络

ovs-vsctl list-br
ovs-vsctl show

修改bug

quantum里面有一个bug，这个环境重启以后nova会无法启动，参考aass修改源码可以解决

修改计算节点/usr/share/pyshared/nova/virt/libvirt/vif.py第360行所在函数

def plug_ovs_hybrid(self, instance, vif):
    network, mapping = vif
    iface_id = self.get_ovs_interfaceid(mapping)
    br_name = self.get_br_name(mapping['vif_uuid'])
    v1_name, v2_name = self.get_veth_pair_names(mapping['vif_uuid'])

    if not linux_net.device_exists(br_name):
        utils.execute('brctl', 'addbr', br_name, run_as_root=True)
        utils.execute('brctl', 'setfd', br_name, 0, run_as_root=True)
        utils.execute('brctl', 'stp', br_name, 'off', run_as_root=True)

    if not linux_net.device_exists(v2_name):
        linux_net._create_veth_pair(v1_name, v2_name)
        utils.execute('ip', 'link', 'set', br_name, 'up', run_as_root=True)
        try:
            v1_tap="tap"+br_name[3:]
            try:
                utils.execute('ovs-vsctl', 'del-port', br_name, v1_tap, run_as_root=True)
            except Exception,e:
                pass
            utils.execute('brctl', 'addif', br_name, v1_name, run_as_root=True)
        except Exception,e:
            pass
        linux_net.create_ovs_vif_port(self.get_bridge_name(network),
                                      v2_name, iface_id, mapping['mac'],
                                      instance['uuid'])

其他可能问题

网卡配置问题

装完系统发现网卡竟然不亮，主要是服务器上有5个网卡，而我们只用到2-3个，结果是啥？结果就是配置了eth0和eth1，你却插到了eth5和eth6……

解决方法是利用ubuntu下的mii-tool命令，一个一个排查，看看是否插对了网卡

配置子网的问题

多个网卡意味着多个网段，在/etc/network/interfaces下是不能配置多个gateway的，解决的方式就是通过增加静态路由，这个可以参考网上的方式

发现子网没法访问，可以使用route add -net 172.16.0.0/16 dev eth0 来增加网络访问

这个问题可以通过route来查看自己网络的联通情况

终端命令行问题

1.执行keystone user-list时，遇到错误“Invalid Openstack Identity credentials".

解决：/etc/keystone/keystone.conf里的admintoken要与环境变量SERVICETOKEN相同值。

2.执行nova flavor-list时，遇到错误"Invalid Openstack Nova Credentials."

解决：环境变量OSUSERNAME, OSPASSWORD, OSTENANTNAME等指定的username，passowrd，tenant应该存在于keystone里，如上所述。可以通过nova --debug flavor-list获得调试信息。

3.使用ubuntu官网镜像时需要使用密钥才能登录

创建密钥 ssh-keygen 上传密钥 nova keypair-add --pubkey .ssh/idrsa.pub key1 创建虚拟机时选择相应密钥使用密钥登录 ssh -i .ssh/id_rsa ubuntu@192.168.22.35

4.网络虚拟机里不能git clone 修改mtu值 sudo ifconfig eth0 mtu 1000
