|
# cp /etc/my.cnf /etc/my.cnf.bak
# rpm -ql mariadb
# vim /etc/my.cnf.d/server.cnf
[mysqld]
bind-address = 0.0.0.0
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect =
'SET NAMES utf8'
character-
set
-server = utf8
|
3、启动mariadb数据库
|
1
2
|
# systemctl enable mariadb.service
# systemctl start mariadb.service
|
三、安装消息队列服务

|
2、启动rabbit服务
|
1
2
|
# systemctl enable rabbitmq-server.service
# systemctl start rabbitmq-server.service
|
3、设置rabbit服务密码
|
1
|

|
四、安装keyston用户认证组件
1、创建keystone数据库和授权用户
|
1
2
3
4
|
mysql -u root -p
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO
'keystone'
@
'localhost'
IDENTIFIED BY
'keystone'
;
GRANT ALL PRIVILEGES ON keystone.* TO
'keystone'
@
'%'
IDENTIFIED BY
'keystone'
;
|
2、安装keystone组件包
|
1
|
# yum -y install openstack-utils openstack-keystone python-keystoneclient
|
3、配置keystone文件
|
1
2
3

|
# cp /etc/keystone/keystone.conf /etc/keystone/keystone.conf.bak
# vim /etc/keystone/keystone.conf
[DEFAULT]
verbose = True
[database]
connection = mysql:
//keystone
:keystone@controller
/keystone
[token]
provider = keystone.token.providers.uuid.Provider
driver = keystone.token.persistence.backends.sql.Token
|
4、创建证书和秘钥文件
|
1
2
3
4
|
# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone
# chown -R keystone:keystone /var/log/keystone
# chown -R keystone:keystone /etc/keystone/ssl
# chmod -R o-rwx /etc/keystone/ssl
|
5、同步keystone到mariadb数据库
|

|
# su -s /bin/sh -c "keystone-manage db_sync" keystone
|
6、启动keystone服务并开机自启动
|
1
2
|
# systemctl enable openstack-keystone.service
# systemctl start openstack-keystone.service
|
7、清除过期的令牌
默认情况下，身份服务存储在数据库中过期的令牌无限。到期令牌的积累大大增加数据库的大小，可能会降低服务的性能，特别是在资源有限的环境中。我们建议您使用cron配置一个周期性任务，清除过期的令牌时
|
1
2
3
|
# (crontab -l -u keystone 2>&1 | grep -q token_flush) || \
echo
'@hourly /usr/bin/keystone-manage token_flush >/var/log/keystone/keystone-tokenflush.log 2>&1'
\
>>
/var/spool/cron/keystone
|
----------------------------Create tenants,user,and roles---------------------------------
1、配置admin的token

|
# export OS_SERVICE_TOKEN=$(openssl rand -hex 10)
# export OS_SERVICE_ENDPOINT=http://controller:35357/v2.0
# echo $OS_SERVICE_TOKEN > ~/ks_admin_token
# openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token $OS_SERVICE_TOKEN
# service openstack-keystone restart

# keystone role-create --name admin
b.Add the admin tenant and user to the admin role:
# keystone user-role-add --tenant admin --user admin --role admin
c.By default, the dashboard limits access to
users
with the _member_ role.
# keystone role-create --name _member_
d.Add the admin tenant and user to the _member_ role:
# keystone user-role-add --tenant admin --user admin --role _member_

15、在控制节点上重新启动API服务
|
1
|
# systemctl restart openstack-nova-api.service
|
七、安装配置dashboard
1、安装dashboard和所需的和依赖包
|
1
|
# yum install openstack-dashboard httpd mod_wsgi memcached python-memcached
|
2、修改dashboard配置文件

# cp /etc/openstack-dashboard/local_settings /etc/openstack-dashboard/local_settings.bak
# vim /etc/openstack-dashboard/local_settings
OPENSTACK_HOST =
"controller"
ALLOWED_HOSTS = [
'*'
]
CACHES = {
'default'
: {
'BACKEND'
:
'django.core.cache.backends.memcached.MemcachedCache'
,
'LOCATION'
:
'127.0.0.1:11211'
,
}
}
TIME_ZONE =
"TIME_ZONE"
|
3、运行web服务连接OpenStack服务
|
1
|
# setsebool -P httpd_can_network_connect on
|
4、由于包装缺陷，仪表板不能正确加载CSS。运行以下命令来解决这个问题：
|
1
|
# chown -R apache:apache /usr/share/openstack-dashboard/static
|
5、启动Web服务器和会话存储服务和配置启动系统启动时：
|
1
2
|
# systemctl enable httpd.service memcached.service
# systemctl start httpd.service memcached.service
|
八、访问测试
1、基于HTTP进行访问测试：
