基于OpenStack构建企业私有云（2）KeyStone

1.安装keystone

# yum install -y openstack-keystone httpd mod_wsgi memcached python-memcached

2.设置Memcache开启启动并启动Memcached

[root@linux-node1 ~]# systemctl enable memcached.service
[root@linux-node1 ~]# vim /etc/sysconfig/memcached
PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 192.168.56.11,::1"
[root@linux-node1 ~]# systemctl start memcached.service

3.Keystone配置

1）配置KeyStone数据库

[root@linux-node1 ~]# vim /etc/keystone/keystone.conf
[database]
connection = mysql+pymysql://keystone:keystone@192.168.56.11/keystone

2）设置Token和Memcached

[token]
provider = fernet

3）.同步数据库：

[root@linux-node1 ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone
[root@linux-node1 ~]# mysql -h 192.168.56.11 -ukeystone -pkeystone -e " use keystone;show tables;"

4）初始化fernet keys

[root@linux-node1 ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
[root@linux-node1 ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

5）初始化keystone

[root@linux-node1 ~]# keystone-manage bootstrap --bootstrap-password admin 
 --bootstrap-admin-url http://192.168.56.11:35357/v3/ 
 --bootstrap-internal-url http://192.168.56.11:35357/v3/ 
 --bootstrap-public-url http://192.168.56.11:5000/v3/ 
 --bootstrap-region-id RegionOne

 6）.验证Keystone配置

[root@linux-node1 ~]# grep "^[a-z]" /etc/keystone/keystone.conf
connection = mysql+pymysql://keystone:keystone@192.168.56.11/keystone
provider = fernet

7）KeyStone启动 [root@linux-node1 ~]# vim /etc/httpd/conf/httpd.conf

ServerName 192.168.56.11:80
创建配置文件
[root@linux-node1 ~]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

启动keystone，并查看端口。

[root@linux-node1 ~]# systemctl enable httpd.service
[root@linux-node1 ~]# systemctl start httpd.service

设置环境变量

[root@linux-node1 ~]# export OS_USERNAME=admin
[root@linux-node1 ~]# export OS_PASSWORD=admin
[root@linux-node1 ~]# export OS_PROJECT_NAME=admin
[root@linux-node1 ~]# export OS_USER_DOMAIN_NAME=Default
[root@linux-node1 ~]# export OS_PROJECT_DOMAIN_NAME=Default
[root@linux-node1 ~]# export OS_AUTH_URL=http://192.168.56.11:35357/v3
[root@linux-node1 ~]# export OS_IDENTITY_API_VERSION=3
