這里有您想知道的互聯(lián)網(wǎng)營銷解決方案

在CentOS 7上安裝OpenStack Mitaka版本

前言：openstack真是一個(gè)龐然大物，想要吃透還真不容易，所以在對openstack大概有了一個(gè)了解的時(shí)候，就應(yīng)該是部署，雖然openstack的安裝方式有rdo或者devstack等一鍵安裝工具，但是最好淺嘗輒止，有了大概的使用經(jīng)驗(yàn)之后就應(yīng)該是從頭到尾的安裝一遍了，不然對于那些報(bào)錯(cuò)，以及故障的解決一定是不夠氣定神閑的，因此，當(dāng)你有了openstack的基本認(rèn)識(shí)后，開始安裝吧~

注：openstack的官方文檔寫得真的是，好的不要不要的，但是看英文總是感覺有點(diǎn)不溜，因此在官方文檔的基礎(chǔ)上寫得這篇筆記。

下面是小編為你精選的Openstack相關(guān)知識(shí)，看看是否有你喜歡的：

首先應(yīng)該是大概的規(guī)劃，需要幾個(gè)節(jié)點(diǎn)，選擇什么操作系統(tǒng)，網(wǎng)絡(luò)怎么劃分~

下面是我的大概規(guī)劃

節(jié)點(diǎn)數(shù)：2 (控制節(jié)點(diǎn)，計(jì)算節(jié)點(diǎn))

操作系統(tǒng)：CentOS Linux release 7.2.1511 (Core)

網(wǎng)絡(luò)配置：

控制節(jié)點(diǎn)： 10.0.0.101 192.168.15.101

結(jié)算節(jié)點(diǎn)： 10.0.0.102 192.168.15.102

先決條件：

The following minimum requirements should support a proof-of-concept environment with core services and several CirrOS instances:

Controller Node: 1 processor, 4 GB memory, and 5 GB storage

Compute Node: 1 processor, 2 GB memory, and 10 GB storage

官方建議概念驗(yàn)證的最小硬件需求。

控制節(jié)點(diǎn) 1 處理器，4 GB內(nèi)存，5 GB硬盤

計(jì)算節(jié)點(diǎn) 1 處理器，2 GB內(nèi)存，10 GB硬盤

# -*- mode: ruby -*-
# vi: set ft=ruby :
Vagrant.configure(2) do |config|
config.vm.box = "centos7"
node_servers = { :control => ['10.0.0.101','192.168.15.101'],
:compute => ['10.0.0.102','192.168.15.102']
}
node_servers.each do |node_name,node_ip|
config.vm.define node_name do |node_config|

v.cpus = 1
end
end
end
end

通過vagrant up一條命令，稍等一會(huì)，兩個(gè)熱騰騰的虛擬機(jī)就出爐了，我們的環(huán)境就OK了~~

環(huán)境如下

操作系統(tǒng)：CentOS Linux release 7.2.1511 (Core)

網(wǎng)絡(luò)配置：

控制節(jié)點(diǎn)： 10.0.0.101 192.168.15.101

結(jié)算節(jié)點(diǎn)： 10.0.0.102 192.168.15.102

注意：上面的config.vm.box = "centos7"，首先需要有個(gè)centos7的box

在開始部署前，我們先捋一捋openstack安裝步驟

首先是軟件環(huán)境準(zhǔn)備，我們需要將一些通用的軟件以及源倉庫等進(jìn)行配置，基本如下

NTP服務(wù)器

控制節(jié)點(diǎn)，其他節(jié)點(diǎn)

openstack 安裝包倉庫

通用組件：

SQL 數(shù)據(jù)庫 ===> MariaDB

NoSQL 數(shù)據(jù)庫 ==> MongoDB(基本組件不需要，)

消息隊(duì)列 ==> RabbitMQ

Memcached

再就是openstack整個(gè)框架下的各個(gè)組件，基本組件如下

認(rèn)證服務(wù) ===> Keystone

鏡像服務(wù) ===> Glance

計(jì)算資源服務(wù) ===> Nova

網(wǎng)絡(luò)資源服務(wù) ===> Neutron

Dashboard ===> Horizon

塊存儲(chǔ)服務(wù) ===> Cinder

其他存儲(chǔ)服務(wù)，如下

文件共享服務(wù) ===> Manila

對象存儲(chǔ)服務(wù) ===> Swift

其他組件，如下

編排服務(wù) ===> Heat

遙測服務(wù) ===> Ceilometer

數(shù)據(jù)庫服務(wù) ===> Trove

環(huán)境準(zhǔn)備

域名解析：

在各個(gè)節(jié)點(diǎn)編輯hosts文件,加入以下配置

10.0.0.101 controller

10.0.0.102 compute

ntp時(shí)間服務(wù)器

控制節(jié)點(diǎn)

1) 安裝chrony軟件包

yum install chrony

2) 編輯配置文件 /etc/chrony.conf，添加以下內(nèi)容，202.108.6.95可根據(jù)自己需求自行更改。

server 202.108.6.95 iburst

allow 10.0.0.0/24

3)加入自啟動(dòng)，并啟動(dòng)

# systemctl enable chronyd.service

# systemctl start chronyd.service

其他節(jié)點(diǎn)

1) 安裝chrony軟件包

yum install chrony

2) 編輯配置文件 /etc/chrony.conf，添加以下內(nèi)容

server controller iburst

allow 10.0.0.0/24

3)加入自啟動(dòng)，并啟動(dòng)

# systemctl enable chronyd.service

# systemctl start chronyd.service

驗(yàn)證：

控制節(jié)點(diǎn)

chronyc sources

210 Number of sources = 2

MS Name/IP address Stratum Poll Reach LastRx Last sample

=============================================================

^- 192.0.2.11 2 7 12 137 -2814us[-3000us] +/- 43ms

^* 192.0.2.12 2 6 177 46 +17us[ -23us] +/- 68ms

其他節(jié)點(diǎn)

# chronyc sources

210 Number of sources = 1

MS Name/IP address Stratum Poll Reach LastRx Last sample

===============================================================================

^* controller 3 9 377 421 +15us[ -87us] +/- 15ms

openstack 安裝包倉庫

安裝相應(yīng)openstack版本yum源

yum install centos-release-openstack-mitaka

系統(tǒng)更新

yum upgrade

注：如果系統(tǒng)內(nèi)核有更新，需要重啟

安裝openstackclient，openstack-selinux

yum install python-openstackclient
yum install openstack-selinux

注：如果報(bào)什么 Package does not match intended download，則yum clean all或者直接下載rpm包安裝吧。

SQL數(shù)據(jù)庫

安裝

1 yum install mariadb mariadb-server python2-PyMySQL

創(chuàng)建/etc/my.cnf.d/openstack.cnf配置文件，加入以下內(nèi)容

#綁定IP
[mysqld]
bind-address = 10.0.0.11
#設(shè)置字符集等
default-storage-engine = innodb .
innodb_file_per_table
collation-server = utf8_general_ci
character-set-server = utf8

配置啟動(dòng)項(xiàng)，啟動(dòng)等

systemctl enable mariadb.service
systemctl start mariadb.service

數(shù)據(jù)庫初始化，創(chuàng)建root密碼等，操作如下

mysql_secure_installation

Enter current password for root (enter for none):[Enter]

Set root password? [Y/n] Y

New password: openstack

Re-enter new password:openstack

Remove anonymous users? [Y/n] Y

Disallow root login remotely? [Y/n] n

Remove test database and access to it? [Y/n] Y

Reload privilege tables now? [Y/n] Y

消息隊(duì)列rabbitmq

安裝

yum install rabbitmq-server

配置啟動(dòng)項(xiàng)，啟動(dòng)

systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

添加openstack用戶

rabbitmqctl add_user openstack RABBIT_PASS

設(shè)置openstack用戶的權(quán)限，依次分別為寫，讀，訪問

rabbitmqctl set_permissions openstack ".*"".*"".*"

NoSQL Mongodb

安裝

yum install mongodb-server mongodb

配置/etc/mongod.conf配置文件

bind_ip = 10.0.0.11
#smallfile=true可選
smallfiles = true

配置啟動(dòng)項(xiàng)，啟動(dòng)

# systemctl enable mongod.service
# systemctl start mongod.service

Memcached

安裝

# yum install memcached python-memcached

配置啟動(dòng)項(xiàng)，啟動(dòng)

# systemctl enable memcached.service
# systemctl start memcached.service

至此，openstack整個(gè)框架的軟件環(huán)境基本搞定，下面就是各組件了。

安裝各組件很有意思，除了keystone基本上是差不多的步驟，唯一的區(qū)別就是創(chuàng)建時(shí)指定的名字不同而已，基本是一般以下步驟。

1)配置數(shù)據(jù)庫

create database xxx
GRANT ALL PRIVILEGES ON keystone.* TO 'xxxx'@'localhost' \
IDENTIFIED BY 'XXXX_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'xxxx'@'%' \
IDENTIFIED BY 'XXXX_DBPASS';

2)安裝

yum install xxx

3)配置文件

配置各項(xiàng)服務(wù)的連接,比如數(shù)據(jù)庫，rabbitmq等

認(rèn)證配置

特定配置

5)數(shù)據(jù)庫同步

創(chuàng)建需要的表

4)加入啟動(dòng)項(xiàng)，啟動(dòng)

# systemctl enable openstack-xxx.service
# systemctl start openstack-xxxx.service

5)創(chuàng)建用戶，service，endpoint等

openstack user create xxx
openstack service create xxx
openstack endpoint create xxx

6)驗(yàn)證服務(wù)是否成功

注：配置文件的配置建議首先備份，然后為了省略不必要的篇幅，在此說明配置文件的編輯方式，如下。

[DEFAULT]

...

admin_token = ADMIN_TOKEN

上面的內(nèi)容，指明在[DEFAULT]的段落加入admin_token = ADMIN_TOKEN內(nèi)容。

各組件安裝

認(rèn)證服務(wù) Keystone

配置數(shù)據(jù)庫

$ mysql -u root -p
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'KEYSTONE_DBPASS';

安裝

# yum install openstack-keystone httpd mod_wsgi

配置文件/etc/keystone/keystone.conf

admin令牌

[DEFAULT]
...
admin_token = ADMIN_TOKEN

數(shù)據(jù)庫

[database]
...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone

令牌生成方式

[token]
...
provider = fernet

注：上面的ADMIN_TOKEN可用openssl rand -hex 10命令生成，或者填入一串自定義的字符串

數(shù)據(jù)庫同步

# su -s /bin/sh -c "keystone-manage db_sync" keystone

初始化fernet秘鑰。

# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

配置Apache

編輯/etc/httpd/conf/httpd.conf

更改一下內(nèi)容

ServerName controller

創(chuàng)建/etc/httpd/conf.d/wsgi-keystone.conf配置文件，加入以下內(nèi)容

Listen 5000
Listen 35357

WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-public
WSGIScriptAlias / /usr/bin/keystone-wsgi-public
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined

Require all granted

WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
WSGIProcessGroup keystone-admin
WSGIScriptAlias / /usr/bin/keystone-wsgi-admin
WSGIApplicationGroup %{GLOBAL}
WSGIPassAuthorization On
ErrorLogFormat "%{cu}t %M"
ErrorLog /var/log/httpd/keystone-error.log
CustomLog /var/log/httpd/keystone-access.log combined

Require all granted

配置啟動(dòng)項(xiàng)，啟動(dòng)

# systemctl enable httpd.service
# systemctl start httpd.service

創(chuàng)建service，API endpoint

為了避免不必要的篇幅，將admin_token，endpoint url配置到環(huán)境變量。

$ export OS_TOKEN=ADMIN_TOKEN
$ export OS_URL=http://controller:35357/v3
$ export OS_IDENTITY_API_VERSION=3

創(chuàng)建service

$ openstack service create \
--name keystone --description "OpenStack Identity" identity

創(chuàng)建endpoint，依次有public，internal，admin

$ openstack endpoint create --region RegionOne \
identity public http://controller:5000/v3
$ openstack endpoint create --region RegionOne \
identity internal http://controller:5000/v3
$ openstack endpoint create --region RegionOne \
identity admin http://controller:35357/v3

創(chuàng)建域，項(xiàng)目，用戶，角色 domain,project,user,role

創(chuàng)建domain

openstack domain create --description "Default Domain" default

創(chuàng)建project

openstack user create --domain default \
--password-prompt admin

創(chuàng)建admin role

openstack role create admin

將admin角色加入admin項(xiàng)目中

openstack role add --project admin --user admin admin

創(chuàng)建service項(xiàng)目

openstack project create --domain default \
--description "Service Project" service

創(chuàng)建demo項(xiàng)目

openstack project create --domain default \
--description "Demo Project" demo

創(chuàng)建demo用戶

openstack user create --domain default \
--password-prompt demo

創(chuàng)建user角色

openstack role create user

將user角色加入到demo項(xiàng)目中

openstack role add --project demo --user demo user

注：記住創(chuàng)建用戶時(shí)的密碼。

驗(yàn)證admin用戶
