Openstac安裝教程

基礎環境準備
1.禁用selinux
2.卸載firewalld
3.卸載 NetworkManager
4.配置主機IP地址
5.配置主機yum客戶端
6.建立cinder-volumes的卷組
7.導入公鑰
8.安裝依賴軟件包

配置卷組
[root@node1 ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 253:0 0 200G 0 disk
└─vda1 253:1 0 16G 0 part /
vdb 253:16 0 20G 0 disk
安裝卷組管理軟件
[root@node1 ~]# yum -y install lvm2
建立卷組
[root@node1 ~]# pvcreate /dev/vdb
Physical volume "/dev/vdb" successfully created.
建立卷組名爲clinder-volumes
[root@node1 ~]# vgcreate clinder-volumes /dev/vdb
Volume group "clinder-volumes" successfully created
查詢卷組信息
[root@node1 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
clinder-volumes 1 0 0 wz--n- <20.00g <20.00g
導入公鑰
[root@nova ~]# rpm --import RPM-GPG-KEY-CentOS-7
兩臺虛擬機安裝額外軟件包
[root@nova ~]# yum install -y qemu-kvm libvirt-client libvirt-daemon
libvirt-daemon-driver-qemu python-setuptools
配置packstack
• 安裝packstack
[root@vh02 ~]# yum install -y openstack-packstack
修改yum源簽名驗證
[root@node1 ~]#vim /etc/yum.repos.d/base.repo
[base]
name=centos
baseurl=ftp://192.168.1.254/centos 物理機ftp yum源
gpgcheck=1
enabled=1
建立應答文件
[root@node1 ~]# packstack --gen-answer-file answer.ini
修改應答文件
[root@node1 ~]# vim answer.ini
11行 CONFIG_DEFAULT_PASSWORD=Taren1
42 CONFIG_SWIFT_INSTALL=n
75 CONFIG_NTP_SERVERS=192.168.1.254

102 CONFIG_NETWORK_HOSTS=192.168.1.20,192.168.1.30
554 CONFIG_CINDER_VOLUMES_CREATE=n
840 CONFIG_NEUTRON_ML2_TYPE_DRIVERS=flat,vxlan
876 CONFIG_NEUTRON_ML2_VXLAN_GROUP=239.1.1.5
910 CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex
921 CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0
936 CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1
1179 CONFIG_PROVISION_DEMO=n
一鍵部署Openstack
[root@node1 ~]# packstack --answer-file answer.ini
ERROR : The cinder server should contain a cinder-volumes volume group
報錯提示,沒有卷組,卷組名錯誤,正確的應該爲: cinder-volumes
[root@node1 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
clinder-volumes 1 0 0 wz--n- <20.00g <20.00g
修改卷組名稱
[root@node1 ~]# vgrename clinder-volumes cinder-volumes
Volume group "clinder-volumes" successfully renamed to "cinder-volumes"
修改完成後查詢
[root@node1 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
cinder-volumes 1 0 0 wz--n- <20.00g <20.00g
從新部署Openstack
[root@node1 ~]# packstack --answer-file answer.ini

配置br-ex爲外部OVS網橋
[root@node1 ~]# vim /etc/sysconfig/network-scripts/ifcfg-br-ex
ONBOOT=yes
IPADDR=192.168.1.20
PROFIX=24
GATEWAY=192.168.1.254
DEVICE=br-ex
NAME=br-ex
DEVICETYPE=ovs

配置外部OVS網橋端口
[root@node1 ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
NAME=eth0
DEVICETYPE=ovs
TYPE=OVSPort
OVS_BRIDGE=br-ex
ONBOOT=yes

配置Horizon
安裝雖然沒有報錯,但默認沒法打開Horizon,這是一個軟件的配置BUG
咱們修改配置文件
[root@node1 ~]# vim /etc/httpd/conf.d/15-horizon_vhost.conf
WSGIApplicationGroup %{GLOBAL} #在文件內添加這一行
從新載入配置文件
[root@node1 ~]# apachectl graceful
使用瀏覽器打開頁面192.168.1.20
http://192.168.1.20/dashboard/auth/login/?next=/dashboard/
打開後就能夠看到登陸頁面了
初始化環境變量
[root@node1 ~]# source ~/keystonerc_admin
[root@node1 ~(keystone_admin)]# env |grep OS
HOSTNAME=node1
OS_REGION_NAME=RegionOne
OS_PASSWORD=50e519fda73a40eb #默認密碼在這
OS_AUTH_URL=http://192.168.1.20:5000/v2.0
OS_USERNAME=admin #默認管理員帳戶名
OS_TENANT_NAME=admin
可使用openstack help查詢命令信息
[root@node1 ~(keystone_admin)]# openstack help
