[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
bind-address = 192.168.66.197 //修改为控制节点IP，使其他节点可以通过管理网络访问数据库
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
启动服务，设置为开机自启

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

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

管理节点
安装软件

[root@controller ~]# yum -y install etcd
修改配置文件，改为管理节点的IP

ETCD_INITIAL_CLUSTER
ETCD_INITIAL_ADVERTISE_PEER_URLS
ETCD_ADVERTISE_CLIENT_URLS
ETCD_LISTEN_CLIENT_URLS
#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://192.168.66.197:2380"
ETCD_LISTEN_CLIENT_URLS="http://192.168.66.197:2379"

ETCD_INITIAL_CLUSTER_STATE="new"

开启服务并设置为开机自启

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

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

9. 部署keystone认证服务

Identity服务为其他OpenStack服务提供验证和授权服务，为所有服务提供终端目录，其他OpenStack服务将身份认证当作通用统一API来使用。此外，提供用户信息但是不在OpenStack项目中的服务（如LDAP服务）可被整合进先前存在的基础设施中。
为了从identify服务中获益，其他的OpenStack服务需要与他合作。当某个OpenStack服务需要与他合作。当某个OpenStack服务收到来自用户的请求时，该服务询问identify服务，验证该用户是否有权限进行此次请求，身份验证服务包括以下组件服务器：一个中心化的服务器使用RESTful接口来提供认证和授权服务驱动：驱动或服务后端被整合进集中式服务器中。它们被用来访问OpenStack外部仓库的身份信息，并且它们可能已经存在于OpenStack被部署在的基础设施中，如SQL数据库模块：中间件模块运行于使用身份验证服务的OpenStack组件的地址空间中。这些模块拦截服务请求，取出用户凭据，并将它们送入中央服务器寻求授权。中间件模块和OpenStack组件间的整合使用python web服务器网关接口。
当安装OpenStack自身服务时，用户必须将之注册到其OpenStack安装环境的每个服务。身份服务才可以追踪到哪些OpenStack服务已经安装，以及在网络中定位它们。

Keystone服务的安装配置
管理节点操作
配置Mysql数据库及授权

[root@controller ~]# mysql -uroot -pcdp12345

Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 12
Server version: 10.1.20-MariaDB MariaDB Server

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> create database keystone;
Query OK, 1 row affected (0.00 sec)

MariaDB [(none)]> grant all privileges on keyston. to 'keystone'@'localhost' identified by '123456';*
Query OK, 0 rows affected (0.00 sec)

MariaDB [(none)]> grant all privileges on keyston. to 'keystone'@'%' identified by '123456';*

systemctl start neutron-metadata-agent.service

18. 配置compute节点网络服务

安装软件包

[root@compute ~]# yum install -y openstack-neutron-linuxbridge ebtables ipset

配置公共组件

vim /etc/neutron/neutron.conf

[DEFAULT]
auth_strategy = keystone //27
transport_url = rabbit://openstack:123456@controller //570

[oslo_concurrency]
lock_path = /var/lib/neutron/tmp //1180

配置Linux网桥

vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge]
physical_interface_mappings = provider:ens33 //157

[vxlan]
enable_vxlan = false //208

[securitygroup]
enable_security_group = true //193
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver //188

配置计算节点网络服务

vim /etc/nova/nova.conf

[neutron]
url = http://controller:9696 //7534
auth_url = http://controller:35357 //7610
auth_type = password //7640
project_domain_name = default //7631
user_domain_name = default //7657
region_name = RegionOne //7678
project_name = service //7625
username = neutron //7651
password = 123456 //7660

启动服务
systemctl restart openstack-nova-compute.service
systemctl enable neutron-linuxbridge-agent.service
systemctl start neutron-linuxbridge-agent.service

19. 部署Horizon服务

在controller节点安装Horizon服务
安装软件包

[root@controller ~]# yum install openstack-dashboard -y

修改配置文件

vim /etc/openstack-dashboard/local_settings

OPENSTACK_HOST = "controller" //189
OPENSTACK_KEYSTONE_DEFAULT_ROLE = "admin" //191
ALLOWED_HOSTS = ['*'] //38
SESSION_ENGINE = 'django.contrib.sessions.backends.file' //51

配置memcache会话存储

SESSION_ENGINE = 'django.contrib.sessions.backends.cache' //50，添加
CACHES = { //注释166-170 去掉注释159-164
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': 'controller:11211',
}
}
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST //开启身份认证API版本v3 190行
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True //开启domains版本支持 76行

OPENSTACK_API_VERSIONS = { //配置API版本 65行
"identity": 3,
"image": 2,
"volume": 2,
}
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default" //98

OPENSTACK_NEUTRON_NETWORK = { //324

'enable_router': False,
'enable_quotas': False,
'enable_distributed_router': False,
'enable_ha_router': False,
'enable_lb': False,
'enable_firewall': False,
