1、系统环境

# uname -r

3.10.0-327.el7.x86_64

# cat /etc/RedHat-release

CentOS Linux release 7.2.1511 (Core)

2、服务器部署

IP	主机名	角色	配置
192.168.56.108	controller	控制节点	M:4G;C:2C;50G
192.168.56.109	compute	计算节点	M:2G;C:2C;50G

3、基础环境准备

3.1、配置 hosts

# cat /etc/hosts

192.168.56.108 controller

192.168.56.109 compute

3.2、配置时间同步

[root@controller ~]# yum install -y ntp

[root@controller ~]# vim /etc/ntp.conf

15 restrict -6 ::1

16 restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

27 restrict 0.centos.pool.ntp.org nomodify notrap noquery

28 restrict 1.centos.pool.ntp.org nomodify notrap noquery

29 restrict 2.centos.pool.ntp.org nomodify notrap noquery

30 restrict 3.centos.pool.ntp.org nomodify notrap noquery

31 server 127.127.1.0

32 fudge 127.127.1.0 stratum 10

[root@controller ~]# systemctl enable ntpd

[root@controller ~]# systemctl start ntpd

在控制节点和计算节点配置定时任务

[root@compute ~]# crontab -l */5 * * * * /usr/sbin/ntpdate 192.168.56.108 >/dev/null 2>&1

3.3、关闭防火墙

# systemctl stop firewalld

3.4、关闭 selinux

# SELINUX=disabled /etc/selinux/config // 需要重启

3.5、安装基础包

[root@controller ~]# yum install -yhttp://dl.Fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-7.noarch.rpm

[root@controller ~]# yum install -y centos-release-openstack-liberty

[root@controller ~]# yum install -y Python-openstackclient

3.6、安装 mysql

[root@controller ~]# yum install -y mariadb mariadb-server MySQL-python

[root@controller ~]# vim /etc/my.cnf

在 mysqld 模块添加如下几行：

default-storage-engine = innodb

innodb_file_per_table

collation-server = utf8_general_ci

init-connect = ‘SET NAMES utf8’

character-set-server = utf8

[root@controller ~]# systemctl enable mariadb.service

[root@controller ~]# systemctl start mariadb.service

[root@controller ~]# mysql_secure_installation

3.7、安装 rabbitmq

[root@controller ~]# yum install -y rabbitmq-server

[root@controller ~]# systemctl enable rabbitmq-server.service

[root@controller ~]# systemctl start rabbitmq-server.service

[root@controller ~]# rabbitmqctl add_user openstack openstack

Creating user “openstack” …

…done.

[root@controller ~]# rabbitmqctl set_permissions openstack ‘.*’ ‘.*’ ‘.*’

Setting permissions for user “openstack” in vhost “/”…

…done.

[root@controller ~]# rabbitmqctl set_user_tags openstack administrator

[root@controller ~]# rabbitmq-plugins enable rabbitmq_management

[root@controller ~]# systemctl restart rabbitmq-server.service

在浏览器中输入 http://192.168.56.108:15672，默认账户和密码为 guest

登录后将前面创建的 openstack 用户加入到 admin 中，结果如下图：

1、创建数据库

[root@controller ~]# mysql -u root -p

[root@controller ~]# CREATE DATABASE keystone;

[root@controller ~]# GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'PWS';

[root@controller ~]# GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'PWS';

[root@controller ~]# openssl rand -hex 10

2、安装 keystone

yum install openstack-keystone httpd mod_wsgi Python-openstackclient memcached python-memcached

3、启动 memcache

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

4、 设置环境

Edit the /etc/keystone/keystone.conf file and complete the following actions:

In the [DEFAULT] section, define the value of the initial administration token:

[DEFAULT]
...
admin_token = ADMIN_TOKEN

Replace ADMIN_TOKEN with the random value that you generated in a previous step.

In the [database] section, configure database access:

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

Replace KEYSTONE_DBPASS with the password you chose for the database.

In the [memcache] section, configure the Memcache service:

[memcache]
...
servers = localhost:11211

```
In the [token] section, configure the UUID token provider and Memcached driver:
```
1

2

3

4

[token]

...

provider = keystone.token.providers.uuid.Provider

driver = keystone.token.persistence.backends.memcache.Token
```
In the [revoke] section, configure the SQL revocation driver:
```
1

2

3

[revoke]

...

driver = keystone.contrib.revoke.backends.sql.Revoke

(Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

[DEFAULT]
...
verbose = True

Populate the Identity service database:

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

5、 设置 HTTP

Edit the /etc/httpd/conf/httpd.conf file and configure the ServerName option to reference the controller node:
```
ServerName controller
```

Create the /etc/httpd/conf.d/wsgi-keystone.conf file with the following content:

Listen 5000
Listen 35357

<VirtualHost *:5000>
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-public
    WSGIScriptAlias / /var/www/cgi-bin/keystone/main
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    LogLevel info
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined
</VirtualHost>

<VirtualHost *:35357>
    WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}
    WSGIProcessGroup keystone-admin
    WSGIScriptAlias / /var/www/cgi-bin/keystone/admin
    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    LogLevel info
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined
</VirtualHost>

Create the directory structure for the WSGI components:
```
# mkdir -p /var/www/cgi-bin/keystone
```

Copy the WSGI components from the upstream repository into this directory:

# curl http://git.openstack.org/cgit/openstack/keystone/plain/httpd/keystone.py?h=stable/kilo   | tee /var/www/cgi-bin/keystone/main /var/www/cgi-bin/keystone/admin

Adjust ownership and permissions on this directory and the files in it:

# chown -R keystone:keystone /var/www/cgi-bin/keystone
# chmod 755 /var/www/cgi-bin/keystone/*

Restart the Apache HTTP server:

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

6、 设置 HTTP
