3.2入手mysql

Openstack的所有組件除了Horizon，都要用到數(shù)據(jù)庫，本文使用的是mysql，在CentOS7中，默認(rèn)叫做MariaDB。

拷貝配置文件

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

修改mysql配置并啟動(dòng)

1[root@linux-node1 ~]# vim /etc/my.cnf（在mysqld模塊下添加如下內(nèi)容）

2[mysqld]

3default-storage-engine = innodb默認(rèn)的存儲(chǔ)引擎

4innodb_file_per_table使用獨(dú)享的表空間

5collation-server = utf8_general_ci設(shè)置校對標(biāo)準(zhǔn)

6init-connect = 'SET NAMES utf8'設(shè)置連接的字符集

7character-set-server = utf8設(shè)置創(chuàng)建數(shù)據(jù)庫時(shí)默認(rèn)的字符集

開機(jī)自啟和啟動(dòng)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

設(shè)置mysql的密碼

1[root@linux-node1 ~]#mysql_secure_installation

創(chuàng)建所有組件的庫并授權(quán)

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

執(zhí)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消息隊(duì)列

SOA架構(gòu)：面向服務(wù)的體系結(jié)構(gòu)是一個(gè)組件模型，它將應(yīng)用程序的不同功能單元（稱為服務(wù)）通過這些服務(wù)之間定義良好的接口和契約聯(lián)系起來。接口是采用中立的方式進(jìn)行定義的，它應(yīng)該獨(dú)立于實(shí)現(xiàn)服務(wù)的硬件平臺(tái)、操作系統(tǒng)和編程語言。這使得構(gòu)建在各種各樣的系統(tǒng)中的服務(wù)可以使用一種統(tǒng)一和通用的方式進(jìn)行交互。

在這里Openstack采用了SOA架構(gòu)方案，結(jié)合了SOA架構(gòu)的松耦合特點(diǎn)，單獨(dú)組件單獨(dú)部署，每個(gè)組件之間可能互為消費(fèi)者和提供者，通過消息隊(duì)列（openstack支持Rabbitmq，Zeromq，Qpid）進(jìn)行通信，保證了當(dāng)某個(gè)服務(wù)當(dāng)?shù)舻那闆r，不至于其他都當(dāng)?shù)簟?/p>

1啟動(dòng)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用戶并授權(quán)

1[root@linux-node1 ~]# rabbitmqctladd_user openstack openstack

2[root@linux-node1 ~]# rabbitmqctlset_permissions openstack ".*" ".*" ".*"

啟用Rabbitmq的web管理插件

1[root@linux-node1 ~]rabbitmq-pluginsenable rabbitmq_management

重啟Rabbitmq

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

查看Rabbit的端口，其中5672是服務(wù)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用戶，設(shè)置權(quán)限，首次登陸必須使用賬號(hào)和密碼必須都是guest

3.4 Keystone組件

修改keystone的配置文件

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

2admin_token = 863d35676a5632e846d9

3用作無用戶時(shí)，創(chuàng)建用戶來鏈接，此內(nèi)容使用openssl隨機(jī)產(chǎn)生

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

5用作鏈接數(shù)據(jù)庫，三個(gè)keysthone分別為keystone組件，keystone用戶名，mysql中的keysthone庫名

切換到keystone用戶，導(dǎo)入keystoe數(shù)據(jù)庫

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（通過切換到keystone用戶下導(dǎo)入數(shù)據(jù)庫，當(dāng)啟動(dòng)的時(shí)候回把日志寫入到該日志中，如果使用root執(zhí)行倒庫操作，則無法通過keysthone啟動(dòng)keystone程序）

631:verbose = true開啟debug模式

71229:servers = 192.168.57.11:11211更改servers標(biāo)簽，填寫memcache地址

81634:driver = sql開啟默認(rèn)sql驅(qū)動(dòng)

91827:provider = uuid開啟并使用唯一識(shí)別碼

101832:driver = memcache(使用用戶密碼生成token時(shí)，存儲(chǔ)到memcache中，高性能提供服務(wù))

查看更改結(jié)果

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

212:admin_token = 863d35676a5632e846d9

配置apache的servername,如果不配置servername，會(huì)影響keystone服務(wù)

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

2ServerName 192.168.56.11:80

啟動(dòng)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'

查看httpd占用端口情況

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