3.1 CentOS7的时间同步服务器chrony

下载chrony

1\[root@linux-node1 ~\]\# yum install -ychrony

修改其配置文件

1\[root@linux-node1 ~\]\# vim/etc/chrony.conf

2allow 192.168/16

chrony开机自启动，并且启动

1\[root@linux-node1 ~\]\#systemctl enablechronyd.service

2\[root@linux-node1 ~\]\#systemctlstartchronyd.service

设置Centos7的时区

1\[root@linux-node1 ~\]\# timedatectlset-timezoneb Asia/Shanghai

查看时区和时间

1\[root@linux-node1 ~\]\# timedatectl status

2Local time: Tue 2015-12-15 12:19:55 CST

3Universal time: Tue 2015-12-15 04:19:55 UTC

4RTC time: Sun 2015-12-13 15:35:33

5Timezone: Asia/Shanghai (CST, +0800)

6NTP enabled: yes

7NTP synchronized: no

8RTC in local TZ: no

9DST active: n/a

10\[root@linux-node1 ~\]\# date

11Tue Dec 15 12:19:57 CST 2015

3.2入手mysql

Openstack的所有组件除了Horizon，都要用到数据库，本文使用的是mysql，在CentOS7中，默认叫做MariaDB。

拷贝配置文件

1\[root\[@linux-node1 ~\]\#cp/usr/share/mysql/my-medium.cnf /etc/my.cnf

修改mysql配置并启动

1\[root@linux-node1 ~\]\# vim /etc/my.cnf(在mysqld模块下添加如下内容)

2\[mysqld\]

3default-storage-engine = innodb默认的存储引擎

4innodb\_file\_per\_table使用独享的表空间

5collation-server = utf8\_general\_ci设置校对标准

6init-connect = 'SET NAMES utf8'设置连接的字符集

7character-set-server = utf8设置创建数据库时默认的字符集

开机自启和启动mysql

1\[root@linux-node1 ~\]\# systemctl enablemariadb.service

2ln -s'/usr/lib/systemd/system/mariadb.service''/etc/systemd/system/multi-user.target.wants/mariadb.service'

3\[root@linux-node1 ~\]\# systemctl startmariadb.service

设置mysql的密码

1\[root@linux-node1 ~\]\#mysql\_secure\_installation

创建所有组件的库并授权

1\[root@linux-node1 ~\]\# mysql -uroot-p123456

执行sql

1CREATE DATABASE keystone;

2GRANT ALL PRIVILEGES ON keystone.\* TO'keystone'@'localhost' IDENTIFIED BY 'keystone';

3GRANT ALL PRIVILEGES ON keystone.\* TO 'keystone'@'%'IDENTIFIED BY 'keystone';

4CREATE DATABASE glance;

5GRANT ALL PRIVILEGES ON glance.\* TO'glance'@'localhost' IDENTIFIED BY 'glance';

6GRANT ALL PRIVILEGES ON glance.\* TO'glance'@'%' IDENTIFIED BY 'glance';

7CREATE DATABASE nova;

8GRANT ALL PRIVILEGES ON nova.\* TO'nova'@'localhost' IDENTIFIED BY 'nova';

9GRANT ALL PRIVILEGES ON nova.\* TO'nova'@'%' IDENTIFIED BY 'nova';

10CREATE DATABASE neutron;

11GRANT ALL PRIVILEGES ON neutron.\* TO'neutron'@'localhost' IDENTIFIED BY 'neutron';

12GRANT ALL PRIVILEGES ON neutron.\* TO'neutron'@'%' IDENTIFIED BY 'neutron';

13CREATE DATABASE cinder;

14GRANT ALL PRIVILEGES ON cinder.\* TO'cinder'@'localhost' IDENTIFIED BY 'cinder';

15GRANT ALL PRIVILEGES ON cinder.\* TO'cinder'@'%' IDENTIFIED BY 'cinder';

3.3 Rabbit消息队列

SOA架构：面向服务的体系结构是一个组件模型，它将应用程序的不同功能单元(称为服务)通过这些服务之间定义良好的接口和契约联系起来。接口是采用中立的方式进行定义的，它应该独立于实现服务的硬件平台、操作系统和编程语言。这使得构建在各种各样的系统中的服务可以使用一种统一和通用的方式进行交互。

在这里Openstack采用了SOA架构方案，结合了SOA架构的松耦合特点，单独组件单独部署，每个组件之间可能互为消费者和提供者，通过消息队列(openstack支持Rabbitmq，Zeromq，Qpid)进行通信，保证了当某个服务当掉的情况，不至于其他都当掉。

1启动Rabbitmq

2\[root@linux-node1 ~\]\# systemctl enablerabbitmq-server.service

3ln -s'/usr/lib/systemd/system/rabbitmq-server.service''/etc/systemd/system/multi-user.target.wants/rabbitmq-server.service'

4\[root@linux-node1 ~\]\# systemctl startrabbitmq-server.service

新建Rabbitmq用户并授权

1\[root@linux-node1 ~\]\# rabbitmqctladd\_user openstack openstack

2\[root@linux-node1 ~\]\# rabbitmqctlset\_permissions openstack ".\*" ".\*" ".\*"

启用Rabbitmq的web管理插件

1\[root@linux-node1 ~\]rabbitmq-pluginsenable rabbitmq\_management

重启Rabbitmq

1\[root@linux-node1 ~\]\# systemctlrestart rabbitmq-server.service

查看Rabbit的端口，其中5672是服务端口，15672是web管理端口，25672是做集群的端口

1\[root@linux-node1 ~\]\# netstat -lntup|grep 5672

2tcp00 0.0.0.0:256720.0.0.0:\*LISTEN52448/beam

3tcp00 0.0.0.0:156720.0.0.0:\*LISTEN52448/beam

4tcp600 :::5672:::\*LISTEN52448/beam

在web界面添加openstack用户，设置权限，首次登陆必须使用账号和密码必须都是guest

alt="" title="">

role设置为administrator，并设置openstack的密码

alt="" title="">

若想要监控Rabbit，即可使用下图中的API

3.4 Keystone组件

修改keystone的配置文件

1\[root@linux-node1 opt\]\# vim/etc/keystone/keystone.conf

2admin\_token = 863d35676a5632e846d9

3用作无用户时，创建用户来链接，此内容使用openssl随机产生

4connection =mysql://keystone:keystone@192.168.56.11/keystone

5用作链接数据库，三个keysthone分别为keystone组件，keystone用户名，mysql中的keysthone库名

切换到keystone用户，导入keystoe数据库

1\[root@linux-node1 opt\]\# su -s /bin/sh-c "keystone-manage db\_sync" keystone

2\[root@linux-node1 keystone\]\# cd /var/log/keystone/

3\[root@linux-node1 keystone\]\# ll

4total 8

5-rw-r--r-- 1 keystone keystone 7064

Dec 15 14:43 keystone.log(通过切换到keystone用户下导入数据库，当启动的时候回把日志写入到该日志中，如果使用root执行倒库操作，则无法通过keysthone启动keystone程序)

631:verbose = true开启debug模式

71229:servers = 192.168.57.11:11211更改servers标签，填写memcache地址

81634:driver = sql开启默认sql驱动

91827:provider = uuid开启并使用唯一识别码

101832:driver = memcache(使用用户密码生成token时，存储到memcache中，高性能提供服务)

查看更改结果

1\[root@linux-node1 keystone\]\#grep -n"^\[a-Z\]" /etc/keystone/keystone.conf

212:admin\_token = 863d35676a5632e846d9

331:verbose = true

4419:connection =mysql://keystone:keystone@192.168.56.11/keystone

51229:servers = 192.168.57.11:11211

61634:driver = sql

71827:provider = uuid

81832:driver = memcache

检查数据库导入结果

添加一个apache的wsgi-keystone配置文件，其中5000端口是提供该服务的，35357是为admin提供管理用的

1\[root@linux-node1 keystone\]\# cat/etc/httpd/conf.d/wsgi-keystone.conf

2Listen 5000

3Listen 35357

42Require all granted

45Order allow,deny

46Allow from all

配置apache的servername,如果不配置servername，会影响keystone服务

1\[root@linux-node1 httpd\]\# vimconf/httpd.conf

2ServerName 192.168.56.11:80

启动memcached，httpd，keystone

1\[root@linux-node1 httpd\]\# systemctlenable memcached httpd

2ln -s'/usr/lib/systemd/system/memcached.service''/etc/systemd/system/multi-user.target.wants/memcached.service'

3ln -s'/usr/lib/systemd/system/httpd.service''/etc/systemd/system/multi-user.target.wants/httpd.service'

4\[root@linux-node1 httpd\]\# systemctl startmemcached httpd

查看httpd占用端口情况

1\[root@linux-node1 httpd\]\# netstat-lntup|grep httpd

2tcp600 :::5000:::\*LISTEN70482/httpd

3tcp600 :::80:::\*LISTEN70482/httpd

4tcp600 :::35357:::\*LISTEN70482/httpd

创建用户并连接keystone，在这里可以使用两种方式，通过keystone–help后家参数的方式，或者使用环境变量env的方式，下面就将使用环境变量的方式,分别设置了token，API及控制版本(SOA种很适用)

1\[root@linux-node1 ~\]\# exportOS\_TOKEN=863d35676a5632e846d9

2\[root@linux-node1 ~\]\# exportOS\_URL=http://192.168.56.11:35357/v3
