Openstack Grizzily 单节点测试机安装( All In One CentOS/RHEL)

Openstack Grizzily版本已经相当完善，根据官方文档安装基本不存在什么问题，但是想快速测试了解Openstack功能的用户非常多，devstack的安 装需要check最新的代码，时常碰到一些bug。这里记录一下我的单节点安装日志，尽量合并，优化一些项目以减少复杂性：

1.安装操作系统: CentOS6.4/RHEL,打开ssh, 配置root,先更新一下yum update

2.6.4的已经包含openstack-grizzly的源:

# yum install -y http://rdo.fedorapeople.org/openstack/openstack-grizzly/rdo-release-grizzly.rpm

# yum install -y http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

3.更新系统

yum update

这次更新比较多，重启一下是个好习惯.

reboot

4.关闭SELINUX,这个导致的问题可不少。

 vi /etc/selinux/config
SELINUX=permissive

5.配置IP:

用setup工具更新

6.安装组件了，为了方便，一次将所有的包都装上,这里只列了一些关键包，根据依赖关系，其它的包应该都会自动装上:

yum  install ntp mysql mysql-server MySQL-python openstack-utils memcached qpid-cpp-server  openstack-nova-novncproxy openstack-utils openstack-keystone python-keystoneclient openstack-glance dnsmasq-utils openstack-cinder openstack-cinder-doc  iscsi-initiator-utils scsi-target-utils openstack-nova python-novaclient git-core memcached python-memcached mod_wsgi openstack-dashboard tomcat6

#如果不需要支持 vmware tomcat6 可以选

6.1. RedHat 下面需要chkconfig 设置所有服务启动模式

chkconfig mysqld on;
chkconfig libvirtd on;
chkconfig qpidd on;
for svc in keystone glance-api glance-registry nova-api nova-objectstore nova-compute nova-network nova-conductor nova-console nova-consoleauth nova-metadata-api nova-xvpvncproxy nova-scheduler nova-cert; do chkconfig openstack-$svc on ; done

7. 配置本地环境变量

vi ~/novarc
export OS_TENANT_NAME=admin
export OS_TENANT_ID=30387eb46b624012bce5172ac77ab407
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL="http://127.0.0.1:35357/v2.0"
export OS_REGION_NAME=RegionOne
export OS_IDENTITY_API_VERSION=2.0
export SERVICE_TOKEN=ADMIN
export SERVICE_ENDPOINT="http://127.0.0.1:35357/v2.0"

echo "source ~/novarc" >> ~/.bashrc

允许ip转发

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

8.创建mysql数据库,一次创建所有的库，可以用http://10.51.166.16/phpmyadmin界面来创建：

keystone;glance;nova;cinder;quantum;

9.配置keystone

sed -i "s/sqlite:////var/lib/keystone/keystone.db/mysql://root:password@127.0.0.1/keystone/g" /etc/keystone/keystone.conf
keystone-manage pki_setup
chown -R keystone:keystone /etc/keystone/*
user script initiate keystone data

restart keystone

初始化各个组件的数据库，Redhat下有openstack-db脚本帮我们初始化很方便:

openstack-db --init --service keystone
keystone-manager db sync
openstack-db --init --service glance
glance-manage db sync
openstack-db --init --service nova
nova-manager db sync
openstack-db --init --service cinder
cinder-manager db sync

10.初始化keystone_db数据，创建用户和服务,这里使用一个脚本，粘到文件中运行，内容如下：

脚本执行完毕，正常输出:

将此id替换novarc文件中相应的值,并重新source

11. 配置glance服务

替换glance-registry.conf 和glance-api.conf中的相关变量

sed -i "s/%SERVICE_TENANT_NAME%/service/g" /etc/glance/glance-registry.conf
sed -i "s/%SERVICE_USER%/service/g" /etc/glance/glance-registry.conf
sed -i "s/%SERVICE_PASSWORD%/password/g" /etc/glance/glance-registry.conf
sed -i "s/#flavor=/flavor=keystone/g" /etc/glance/glance-registry.conf
sed -i "s/sqlite:\/\/\/\/var\/lib\/glance\/glance.sqlite/mysql:\/\/root:password@127.0.0.1\/glance/g" /etc/glance/glance-registry.conf

sed -i "s/%SERVICE_TENANT_NAME%/service/g" /etc/glance/glance-api.conf
sed -i "s/%SERVICE_USER%/service/g" /etc/glance/glance-api.conf
sed -i "s/%SERVICE_PASSWORD%/password/g" /etc/glance/glance-api.conf
sed -i "s/#flavor=/flavor=keystone/g" /etc/glance/glance-api.conf
sed -i "s/sqlite:\/\/\/\/var\/lib\/glance\/glance.sqlite/mysql:\/\/root:password@127.0.0.1\/glance/g" /etc/glance/glance-api.conf

restart glance-api
restart glance-registry

同步数据库

glance image-list

未输出东西则表示正常

12.配置libvirt

删除默认网桥

root@ubuntu:~# virsh net-destroy default
Network default destroyed

root@ubuntu:~# virsh net-undefine default
Network default has been undefined

修改libvirt支持tcp监听

sed -i "s/#listen_tls = 0/listen_tls = 0/g" /etc/libvirt/libvirtd.conf
sed -i "s/#listen_tcp = 1/listen_tcp = 1/g" /etc/libvirt/libvirtd.conf
sed -i "s/#auth_tcp = "sasl"/auth_tcp = "none"/g" /etc/libvirt/libvirtd.conf

sed -i "s/env libvirtd_opts=\"-d\"/env libvirtd_opts=\"-d -l\"/g" /etc/init/libvirt-bin.conf

vi /etc/libvirt/qemu.conf

cgroup_device_acl = [
"/dev/null", "/dev/full", "/dev/zero",
"/dev/random", "/dev/urandom",
"/dev/ptmx", "/dev/kvm", "/dev/kqemu",
"/dev/rtc","/dev/hpet","/dev/net/tun"
]

restart libvirt-bin

13. 配置nova

sed -i "s/%SERVICE_TENANT_NAME%/service/g" /etc/nova/api-paste.ini
sed -i "s/%SERVICE_USER%/service/g" /etc/nova/api-paste.ini
sed -i "s/%SERVICE_PASSWORD%/password/g" /etc/nova/api-paste.ini

vi nova.conf

vi /etc/nova/nova-compute.conf

[DEFAULT]
libvirt_type=kvm
compute_driver=libvirt.LibvirtDriver
libvirt_ovs_bridge=br-int
libvirt_vif_type=ethernet
libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtHybridOVSBridgeDriver
libvirt_use_virtio_for_bridges=True

同步nova 数据库

nova-manage db sync

14. 配置cinder

启用iscsi

sed -i 's/false/true/g' /etc/default/iscsitarget

sed -i "s/%SERVICE_TENANT_NAME%/service/g" /etc/cinder/api-paste.ini
sed -i "s/%SERVICE_USER%/service/g" /etc/cinder/api-paste.ini
sed -i "s/%SERVICE_PASSWORD%/password/g" /etc/cinder/api-paste.ini

echo "sql_connection = mysql://root:password@127.0.0.1/cinder" >> /etc/cinder/cinder.conf
echo "notification_driver=cinder.openstack.common.notifier.rpc_notifier" >> /etc/cinder/cinder.conf

cinder-manage db sync

如果没有未使用的分区或者磁盘，只能使用虚拟文件来代替

dd if=/dev/zero of=cinder-volumes bs= count= seek=2G
losetup /dev/loop2 cinder-volumes
fdisk /dev/loop2
#Type in the followings:
n
p

ENTER
ENTER
t
8e
w

创建cinder-volumes

pvcreate /dev/loop2
vgcreate cinder-volumes /dev/loop2

15.配置quantum

sed -i "s/%SERVICE_TENANT_NAME%/service/g" /etc/quantum/metadata_agent.ini
sed -i "s/%SERVICE_USER%/service/g" /etc/quantum/metadata_agent.ini
sed -i "s/%SERVICE_PASSWORD%/password/g" /etc/quantum/metadata_agent.ini

sed -i "s/%SERVICE_TENANT_NAME%/service/g" /etc/quantum/quantum.conf
sed -i "s/%SERVICE_USER%/service/g" /etc/quantum/quantum.conf
sed -i "s/%SERVICE_PASSWORD%/password/g" /etc/quantum/quantum.conf

#打开LB支持

sed -i "s/# service_plugins =/service_plugins = quantum.plugins.services.agent_loadbalancer.plugin.LoadBalancerPlugin/g" /etc/quantum/quantum.conf

sed -i "s/sqlite:\/\/\/\/var\/lib\/quantum\/ovs.sqlite/mysql:\/\/root:password@127.0.0.1\/quantum/g" /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini vi /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini

在尾部增加

[OVS]
tenant_network_type = gre
tunnel_id_ranges = :
enable_tunneling = True
integration_bridge = br-int
tunnel_bridge = br-tun
local_ip = 10.51.166.16

配置open-vswitch

ovs-vsctl add-br br-int
ovs-vsctl add-br br-ex
ovs-vsctl add-port br-ex eth1

这部分可参考:

http://www.cnblogs.com/biangbiang/archive/2013/05/17/3083421.html

下面可以登录Dashboard使用了。

http://10.51.166.16/horizon

Ps:  VMware vCenter 支持的nova配置
compute_driver=vmwareapi.VMwareVCDriver
vmwareapi_host_ip=<vcenter host ip>
vmwareapi_host_username=root
vmwareapi_host_password=passw0rd
vmwareapi_vlan_interface=vmnic4 (change to actually use)
vmwareapi_wsdl_loc=http://127.0.0.1:8080/SDK/vsphere-ws/wsdl/vim25/vimService.wsdl

其它的Openstack命令

不能不说Redhat在openstack项目上后来居上，做的工作更细一下

比如openstackdb 命令

还有openstack-status 可以显示状态
