這篇文章主要介紹了圖文講解OpenStack手動分布式部署環(huán)境準(zhǔn)備(Queens版),OpenStack用于部署公有云、私有云,并實(shí)現(xiàn)對云項目管理,需要的朋友可以參考下

OpenStack簡介

OpenStack是由美國國家航空航天局NASA)與Rackspace公司合作研發(fā)并發(fā)起的,以Apache許可證授權(quán)的自由軟件和開放源代碼的云計算技術(shù)解決方案,其是一個項目也是一個軟件,主要用于實(shí)現(xiàn)云項目,以云項目操作系統(tǒng)而存在。作用: 用于部署公有云、私有云,并實(shí)現(xiàn)對云項目管理。開發(fā)語言: Python

1、基礎(chǔ)環(huán)境準(zhǔn)備(所有節(jié)點(diǎn)執(zhí)行)  

1.1關(guān)閉防火墻

systemctl stop firewalld && systemctl disable firewalld

  1.2關(guān)閉selinux

setenforce 0 && sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

  1.3修改主機(jī)名

#注意改成每個節(jié)點(diǎn)的名字 
hostnamectl set-hostname 節(jié)點(diǎn)名字

  1.4安裝ntp時間服務(wù)器

        【在控制節(jié)點(diǎn)】

yum install chrony
vi /etc/chrony.conf

systemctl enable chronyd.service && systemctl start chronyd.service

         【在其他節(jié)點(diǎn)】

yum install chrony
server controller iburst
systemctl enable chronyd.service && systemctl start chronyd.service

  1.5修改域名解析

vi /etc/hosts
172.16.21.37    controller
172.16.21.38    compute
172.16.21.39    cinder

  1.6添加yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install centos-release-openstack-queens -y

  1.7更新軟件包 

yum upgrade

  1.8安裝openstack client端

yum install python-openstackclient -y

  1.9安裝openstack-selinux

yum install openstack-selinux -y

2、數(shù)據(jù)庫安裝配置(controller節(jié)點(diǎn)執(zhí)行)  

2.1安裝數(shù)據(jù)庫

yum install mariadb mariadb-server python2-PyMySQL -y

  2.2修改數(shù)據(jù)庫

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
bind-address = 172.16.21.37
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

  2.3重啟數(shù)據(jù)庫

systemctl enable mariadb.service;systemctl start mariadb.service

  2.4初始化數(shù)據(jù)庫

[root@controller ~]# mysql_secure_installation
 
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
 
In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
 
Enter current password for root (enter for none): 
OK, successfully used password, moving on...
 
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
 
Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!
 
 
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.
 
Remove anonymous users? [Y/n] y
 ... Success!
 
Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.
 
Disallow root login remotely? [Y/n] n
 ... skipping.
 
By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.
 
Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!
 
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
 
Reload privilege tables now? [Y/n] y
 ... Success!
 
Cleaning up...
 
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
 
Thanks for using MariaDB!

3、安裝RabbitMq并配置(controller節(jié)點(diǎn)執(zhí)行)

  • RabbitMq是一種應(yīng)用程序?qū)?yīng)用程序的通信方法。應(yīng)用程序通過讀寫出入隊列的消息(針對應(yīng)用程序的數(shù)據(jù))來通信,而無需專用連接來鏈接它們。
  • 消息傳遞指的是程序之間通過在消息中發(fā)送數(shù)據(jù)進(jìn)行通信,而不是通過直接調(diào)用彼此來通信,直接調(diào)用通常是用于諸如遠(yuǎn)程過程調(diào)用的技術(shù)。
  • 排隊指的是應(yīng)用程序通過隊列來通信。隊列的使用除去了接收和發(fā)送應(yīng)用程序同時執(zhí)行的要求。

3.1安裝RabbitMq

yum install -y rabbitmq-server

  3.2啟動并配置開機(jī)啟動

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

        查看是否啟動成功 

systemctl status rabbitmq-server.service

  3.3添加 openstack 用戶

rabbitmqctl add_user openstack 000000

  3.4給openstack用戶開放權(quán)限

rabbitmqctl set_user_tags openstack administrator
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

        查看一下

[root@controller ~]# rabbitmqctl list_users
Listing users
openstack	[administrator]
guest	[administrator]

        打開RabbitMq圖像界面(這一步可以不做)

rabbitmq-plugins enable rabbitmq_management
  • web界面登陸測試:
  • http://172.16.14.224:15672 使用openstack/000000登陸即可 

4、安裝memcached(controller節(jié)點(diǎn)執(zhí)行)

  1. memcached是一個開源的、高性能的分布式內(nèi)存對象緩存系統(tǒng)。
  2. 通過在內(nèi)存中緩存數(shù)據(jù)和對象來減少讀取數(shù)據(jù)庫的次數(shù),從而提高網(wǎng)站訪問速度,減輕數(shù)據(jù)庫負(fù)載。
  3. memcached是一種內(nèi)存緩存,把經(jīng)常需要存儲的對象或數(shù)據(jù)存在內(nèi)存中。
  4. 在內(nèi)存中數(shù)據(jù)通過API的方式被存取,數(shù)據(jù)經(jīng)過利用HASH之后被存放到位于內(nèi)存上的HASH表內(nèi),HASH表中的數(shù)據(jù)已key-value的形式存放,由于Memcached滅有實(shí)現(xiàn)訪問認(rèn)證及安全管理控制,因此在面向Internet的系統(tǒng)架構(gòu)中,Memcached服務(wù)器通常位于用戶的安全區(qū)域。
yum install memcached python-memcached -y

        修改配置

[root@controller ~]# vi /etc/sysconfig/memcached 
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l controller"                                 
systemctl enable memcached.service;systemctl start memcached.service

        查看是否啟動成功 

systemctl status memcached.service

        檢查一下memcache端口: 

5、Etcd服務(wù)安裝(controller節(jié)點(diǎn)執(zhí)行)  

5.1安裝服務(wù)

yum install etcd -y 

  5.2編輯/etc/etcd/etcd.conf文件 

 
vi /etc/etcd/etcd.conf
 
ETCD_INITIAL_CLUSTER
ETCD_INITIAL_ADVERTISE_PEER_URLS
ETCD_ADVERTISE_CLIENT_URLS
ETCD_LISTEN_CLIENT_URLS
#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://172.16.14.224:2380"
ETCD_LISTEN_CLIENT_URLS="http://172.16.14.224:2379"
ETCD_NAME="controller"
#[Clustering]
ETCD_INITIAL_ADVERTISE_PEER_URLS="http://172.16.14.224:2380"
ETCD_ADVERTISE_CLIENT_URLS="http://172.16.14.224:2379"
ETCD_INITIAL_CLUSTER="controller=http://172.16.14.224:2380"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
ETCD_INITIAL_CLUSTER_STATE="new"

  5.3設(shè)置服務(wù)開機(jī)啟動 

systemctl enable etcd;
systemctl start etcd
