CentOS6.5本地源安裝OpenstackIcehouse 網路型別neutron-flat 原創

阿新 • • 發佈：2019-02-03

本片部落格主要針對openstack的快速安裝，本人親自制作，決定轉載和抄襲。

注：本次實驗本人已安裝成功，以下yum安裝後的提示為正常提示。本文件是對實驗步驟的一個總結。本次實驗各個服務的安裝、配置，本人都寫到了固定指令碼中，下載連結：

本次實驗環境

1 Centos6.5 X86_64位英文版minimal安裝環境

3 雙節點（controller、compute）

4 每個節點雙網絡卡:

eth0 管理、公共

eth1 私有、提供虛擬機器IP地址

5 使用virtualbox虛擬化軟體

效能需求：

controller：2G記憶體、100G硬碟、雙網絡卡

compute：4G記憶體、120G硬碟、雙網絡卡

virtualbox網路設定如下圖：

具體步驟如下：

1 安裝系統

使用virtualBox建立兩臺虛擬機器，一臺為controller節點、一臺為compute節點。

建立的虛擬機器配置如下圖所示：

以上為控制點的主要配置。計算點配置類似，就是記憶體設定大點即可。

在安裝系統過程中，需要注意以下幾點

（1）建議選擇全英文安裝，這樣在安裝過程中會很快

（2）時區選擇時，選擇Asia/Shanghai時區，取消系統自動更新時區勾選

（3）分割槽時，一般選擇自定義分割槽。本人的分割槽主要有：根目錄50G、/boot分割槽200M、swap分割槽（設定為記憶體的2倍）、建立一塊沒有掛載點的分割槽（10G，留著以後做cinder和swift，計算點就設定兩塊沒有掛載點的分割槽）

（4）選擇系統型別時，建議雙節點全部選擇為minimal，這樣安裝就會節約很多時間

2 基本設定

系統正常安裝後做如下設定：

controller節點：

（1）[[email protected] ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter mangle na[ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[

[email protected] ~]# chkconfig iptables off
[[email protected] ~]#

（2）修改selinux為disabled

[[email protected] ~]# cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted
（3）修改主機名

[[email protected] ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.20.0.200 controller
10.20.0.201 compute

[[email protected] ~]#

（4）關閉iptables服務，關閉開機自啟

[[email protected] ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter mangle na[ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[[email protected] ~]# chkconfig iptables off
[[email protected] ~]#
（5）修改yum源，本次實驗使用的源為本地源，所以我們需要把系統自帶的源更改。把/etc/yum.repos.d/目錄下的檔案進行備份，然後建立local.repo檔案

[[email protected] ~]# cat /etc/yum.repos.d/local.repo
[centos]
baseurl=file:///opt/centos
gpgcheck=0
enabled=1
[openstack-icehouse]
baseurl=file:///opt/iaas-repo
gpgcheck=0
enabled=1
[[email protected] ~]#

以上都是controller點的前期準備工作。

compute節點：

（1）修改網絡卡

[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=08:00:27:C1:53:F2
TYPE=Ethernet
UUID=30923f68-51f3-41e5-bb79-6061b213378a
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=no
IPADDR=10.20.0.201
NETMASK=255.255.255.0
GATEWAY=10.20.0.1
[[email protected] ~]#
（2）修改主機名

（3）修改yum源，我們在控制點上安裝FTP伺服器，然後計算點所使用的源全部來自此伺服器。先把/etc/yum.repos.d/目錄下的檔案進行備份，然後建立local.repo檔案

[[email protected] ~]# cat /etc/yum.repos.d/local.repo
[centos]
baseurl=ftp://10.20.0.200/centos
gpgcheck=0
enabled=1
[openstack-icehouse]
baseurl=ftp://10.20.0.200/iaas-repo/
gpgcheck=0
enabled=1
[[email protected] ~]#

以上為計算點的前期準備工作

測試：

控制點ping計算點

[[email protected] ~]# ping -c 4 compute
PING compute (10.20.0.201) 56(84) bytes of data.
64 bytes from compute (10.20.0.201): icmp_seq=1 ttl=64 time=0.258 ms

計算點ping控制點

[[email protected] ~]# ping -c 4 controller
PING controller (10.20.0.200) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.176/0.208/0.220/0.023 ms
[[email protected] ~]#

以上都配置完成後，我們重啟兩臺機器

重啟完成後，我們利用FTP上傳工具把源上傳到controller節點的/home目錄。上傳完成後，我們進行以下的操作

[[email protected] home]# mount -o loop CentOS6.5.iso /mnt/
[[email protected] home]# cd /mnt/
[[email protected] mnt]# ll

[[email protected] mnt]# cp -rfv * /opt/centos

複製完成後，我們取消Centos6.5的掛載，然後再把Openstack源進行掛載

[[email protected] ~]# umount /mnt/
[[email protected] ~]# mount -o loop /home/openstack.iso /mnt/
[[email protected] ~]# cd /mnt/
[[email protected] mnt]# ll
total 4
drwxrwxr-x 6 nobody nobody 2048 Nov 13 2015 iaas-repo
drwxrwxr-x 2 nobody nobody 2048 Mar 6 2015 images
[[email protected] mnt]# cp -rfv * /opt/

以上這兩步完成後，我們在controller節點上安裝ftp服務：

[[email protected] ~]# yum install vsftpd -y
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process
Package vsftpd-2.2.2-11.el6_4.1.x86_64 already installed and latest version
Nothing to do
[[email protected] ~]#
然後我們把ftp的目錄進行修改，允許匿名進行訪問，只要在/etc/vsftpd/vsftpd.conf檔案加上：anon_root=/opt/即可

然後重啟ftp服務，並設定開機自啟：

[[email protected] ~]# service vsftpd restart
Shutting down vsftpd: [ OK ]
Starting vsftpd for vsftpd: [ OK ]
[[email protected] ~]# chkconfig vsftpd on
[[email protected] ~]#
最後我們到計算點上進行驗證：

[[email protected] ~]# yum update

yum設定完成後，接著在controller節點安裝、配置ntp服務：

[[email protected] ~]# yum install -y ntp
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process
Package ntp-4.2.6p5-1.el6.centos.x86_64 already installed and latest version
Nothing to do
[[email protected] ~]#
修改ntp配置檔案/etc/ntp.conf：

[[email protected] ~]# cat /etc/ntp.conf
# For more information about this file, see the man pages
# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).

[[email protected] ~]#
啟動ntp，並設定開機自啟：

[[email protected] ~]# service ntpd restart
Shutting down ntpd: [ OK ]
Starting ntpd: [ OK ]
[[email protected] ~]# chkconfig ntpd on
[[email protected] ~]#

然後到計算點同步時間：

[[email protected] ~]# yum install ntp
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process

[[email protected] ~]# ntpdate controller
14 Dec 02:56:14 ntpdate[10847]: adjust time server 10.20.0.200 offset 0.250648 sec
[[email protected] ~]#

然後我們安裝qpid服務，用於openstack各個元件的訊息通訊服務：

[[email protected] ~]# yum install qpid-cpp-server -y
Loaded plugins: fastestmirror, priorities
Repository 'centos' is missing name in configuration, using id
Repository 'openstack-icehouse' is missing name in configuration, using id
Loading mirror speeds from cached hostfile
Setting up Install Process
Package qpid-cpp-server-0.18-18.el6.x86_64 already installed and latest version
Nothing to do

設定qpid認證為否：

[[email protected] ~]#cat /etc/qpidd.conf

[[email protected] ~]#

以上步驟配置完成後，系統的基本設定就OK了，接下來我們要先安裝openstack所需要的基礎服務。

3 安裝openstack所需要的基礎服務，以下服務的安裝都可以通過指令碼進行執行

控制點：

（1）安裝mysql資料庫，執行指令碼install-mysql.sh

（2）安裝keystone服務，執行指令碼install-keystone.sh

驗證：

驗證：

[[email protected] ~]# glance image-list
+--------------------------------------+--------------------------+-------------+--------+
| ID | Name | Disk Format | Container Format | Size | Status |
+--------------------------------------+--------------------------+-------------+--------+
| | | | | | |
+--------------------------------------+--------------------------+-------------+--------+
[[email protected] ~]#

（4）安裝nova服務，執行指令碼install-nova-controller.sh

安裝完成後，我們需要到計算節點把nova服務也安裝一下，執行指令碼：install-nova-compute.sh

兩個節點都安裝成功後，我們在控制節點進行驗證：

[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=08:00:27:B5:CB:CA
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no

IPADDR=172.16.100.10
NETMASK=255.255.255.0
GATEWAY=172.16.100.1

[[email protected] ~]#

[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
HWADDR=08:00:27:DE:5A:BD
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no

IPADDR=172.16.100.20
NETMASK=255.255.255.0
GATEWAY=172.16.100.1

[[email protected] ~]#

兩塊網絡卡設定成功後，先在控制點執行：install-neutron-controller.sh

驗證：

然後到計算點執行：install-neutron-compute.sh

安裝完成後，我們再到控制點進行驗證：

4 以上的基礎服務安裝成功後，我們需要在控制點安裝openstack-dashboard服務，這個服務提供web操作功能：

[[email protected] ~]# yum install -y memcached python-memcached mod_wsgi openstack-dashboard--2014.1.3-1.el6

（openstack-dashboard需要加上版本號，要是不加會提示錯誤）

安裝結束後，設定openstack-dashboard，修改/etc/openstack-dashboard/local_settings

ALLOWED_HOSTS = ['10.20.0.200', 'localhost']

OPENSTACK_HOST = "controller"

取消：

CACHES = {
    'default': {
        'BACKEND' : 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION' : '127.0.0.1:11211',
    }
}

前的註釋

啟動httpd、memcached服務，並且設定開機自啟：

[[email protected] ~]# service httpd restart
Stopping httpd:                                            [ OK ]
Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 10.20.0.200 for ServerName
                                                           [ OK ]
[[email protected] ~]# service memcached restart
Stopping memcached:                                        [ OK ]
Starting memcached:                                        [ OK ]
[[email protected] ~]# chkconfig httpd on
[[email protected] ~]# chkconfig memcached on
[[email protected] ~]#

完成以上步驟後，我們到瀏覽器中開啟：10.20.0.200/dashboard

賬號:admin 密碼:000000

至此，我們的平臺基本搭建成功。接下來我們開啟一臺虛擬機器試試：

1 建立網路

3 上傳映象（映象下載地址：）

4 建立虛擬機器：

5 驗證虛擬機器

至此整個平臺部署完成。
