centos 7.0 安装openstack
参考官方文档：http://docs.openstack.org/juno/install-guide/install/yum/content/#三个节点ip信息
controller:192.168.100.10
network:192.168.100.20
compute1:192.168.100.30
修改各节点的/etc/hosts 文件
测试各节点到openstack.org的连通性
controller node
配置NTP服务
yum install -y ntp
vi /etc/ntp.conf 修改文件如下：
server NTP_SERVER iburst#此处未做修改，采用默认
restrict -4 default kod notrap nomodify
restrict -6 default kod notrap nomodify
systemctlenable ntpd.service #开机启动
systemctlstart ntpd.service
其他节点同样安装
yum install ntp
修改/etc/ntp.conf文件如下：
server controller iburst
开机启动服务：
systemctl enable ntpd.service
systemctl start ntpd.service
OpenStack packages
Install the yum-plugin-priorities package to enable assignment of relative priorities within repositories:
# yum install -y yum-plugin-priorities
Install the epel-release package to enable the EPEL repository:
# yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
Install the rdo-release-juno package to enable the RDO repository:
# yum install http://rdo.fedorapeople.org/openstack-juno/rdo-release-juno.rpm
Upgrade the packages on your system:
# yum upgrade
# reboot
RHEL and CentOS enable SELinux by default. Install the openstack-selinux package to automatically manage security policies for OpenStack services:
# yum install openstack-selinux
安装如果报错，可通过下面安装：
#yum install http://repos.fedorapeople.org/repos/openstack/openstack-juno/epel-7/openstack-selinux-0.5.19-2.el7ost.noarch.rpm
To install and configure the database server
# yum install mariadb mariadb-server MySQL-python
修改/etc/my.cnf
bind-address = 127.0.0.1
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8
# systemctl enable mariadb.service
# systemctl start mariadb.service
To install the RabbitMQ message broker service
# yum install rabbitmq-server
# systemctl enable rabbitmq-server.service
# systemctl start rabbitmq-server.service
启动服务时出现如下错误：
# rabbitmqctl change_password guest 123456
执行时如果有报错
Identity service Install and configure
# mysql
> create database keystone;
> grant all privileges on keystone.* to 'keystone'@'localhost' identified by 'test01';
> grant all privileges on keystone.* to 'keystone'@'%' identified by 'test01';
# openssl rand -hex 10
02456f17dc198d827a90 #值不一样
# yum install openstack-keystone python-keystoneclient
修改 /etc/keystone/keystone.conf
...admin_token= 02456f17dc198d827a90
verbose = True...connection=mysql://keystone:test01@localhost/keystone ...provider = keystone.token.providers.uuid.Providerdriver =keystone.token.persistence.backends.sql.Token
# 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
# su -s /bin/sh -c "keystone-manage db_sync" keystone 或者 keystone-manage db_sync
# systemctl enable openstack-keystone
# systemctl start openstack-keystone
Create tenants, users, and roles
# export OS_SERVICE_TIOEN=02456f17dc198d827a90
# export OS_SERVICE_ENDPOINT=http://controller:35357/v2.0
Create the admin tenant:
# keystone tenant-create --name admin --description "Admin Tenant"
Create the admin user:
# keystone user-create --name admin --pass test01 --email admin@test.com
Create the admin role:
# keystone role-create --name admin
Add the admin role to the admin tenant and user:
# keystone user-role-add --user admin --tenant admin --role admin
Create a demo tenant and user for typical operations in your environment:
Create the demo tenant:
# keystone tenant-create --name demo --description "Demo Tenant"
Create the demo user under the demo tenant:
# keystone user-create --name demo --tenant demo --pass test01 --email admin@test.com
Create the service tenant:
# keystone tenant-create --name service --description "Service Tenant"
Create the service entity for the Identity service:
# keystone service-create --name keystone --type identity --description "Openstack Identity"
Create the Identity service API endpoints:
# keystone endpoint-create --service-id $(keystone service-list | awk '/ identity / {print $2}') --publicurl http://controller:5000/v2.0 --internalurl http://controller:5000/v2.0 --adminurl http://controller:35357/v2.0 --region regionOne
# unset OS_SERVICE_TOKEN OS_SERVICE_ENDPOINT
# keystone --os-tenant-name admin --os-username admin --os-password test01 --os-auth-url http://controller:35357/v2.0 token-get
# keystone --os-tenant-name admin --os-username admin --os-password test01 --os-auth-url http://controller:35357/v2.0 tenant-list

# keystone --os-tenant-name demo --os-username demo --os-password test01 --os-auth-url http://controller:35357/v2.0 user-list
Add the Image Service(in controller node)
To configure prerequisites
#mysql -u root
> create database glance;
> grant all privileges on glance.* to 'glance'@'localhost' identified by 'test01';
> grant all privileges on glance.* to 'glance'@'%' identified by 'test01';
>quit
# source admin-openrc.sh
# keystone user-create --name glance --pass test01 --email admin@test.com
# keystone user-role-add --user glance --tenant service --role admin
# keystone service-create --name glance --type image --description "Openstack Image Service"
# keystone endpoint-create --service-id $(keystone service-list | awk '/ image / {print $2}') --publicurl http://controller:9292 --internalurl http://controller:9292 --adminurl http://controller:9292 --region regionOne
To install and configure the Image Service components
