openstack

++实验环境

系统:centos7

openstack版本:liberty

两台主机

controller 网卡1:192.168.47.139 网卡2:无ip

compute 网卡1:192.168.47.140 网卡2:无ip

基本服务

网卡设置

第一块网卡设置IP地址，

第二块网卡，不需要设置Ip

TYPE=Ethernet

BOOTPROTO=none

NAME=eno33554960

DEVICE=eno33554960

ONBOOT=yes

重启网络

ifdown eno33554960

ifup eno33554960

关闭防火墙和selinux

systemctl disable firewalld.service

systemctl stop firewalld.service

sed -i "s/enforce/disabled/" /etc/selinux/config

重启系统

NTP服务

单节点其实可以忽略，不过同步时间对群集是非常重要的事情，所以我也记录一遍，国内建议使用ntp服务器

yum install chrony

编辑 /etc/chrony.conf

server cn.pool.ntp.org iburst

访问权限

allow 192.168.47.0/24

重启相关服务

systemctl enable chronyd.service

systemctl start chronyd.service

剩下节点，只需要设置ntp server的IP改成控制节点的ip就可以。

验证

chronyc sources

主机名

为了方便，机器采用主机名进行访问，而不是ip

cat >> /etc/hosts << OFF

192.168.47.139 controller

192.168.47.140 compute

OFF

数据库

yum install mariadb mariadb-server MySQL-python

配置

sed -i "/[mysqld]$/a character-set-server = utf8" /etc/my.cnf

sed -i "/[mysqld]$/a init-connect = 'SET NAMES utf8'" /etc/my.cnf

sed -i "/[mysqld]$/a collation-server = utf8_general_ci" /etc/my.cnf

sed -i "/[mysqld]$/a innodb_file_per_table" /etc/my.cnf

sed -i "/[mysqld]$/a default-storage-engine = innodb" /etc/my.cnf

sed -i "/[mysqld]$/a bind-address = 192.168.47.139" /etc/my.cnf

重启服务

systemctl enable mariadb.service

systemctl start mariadb.service

安全设置

mysql_secure_installation

这个还是必须允许，不然你后面会遇到麻烦。

消息队列

yum install -y rabbitmq-server

systemctl enable rabbitmq-server.service

systemctl restart rabbitmq-server.service

创建用户：openstack，设置密码pass

rabbitmqctl add_user openstack pass

设置权限

rabbitmqctl set_permissions openstack ".*" ".*" ".*"

设置源

对于CentOS7，我们需要

1. Base

2. extra

3. update

4. EPEL

5. OpenStack liberty源

前面3个是CentOS默认启用的源。EPEL源和OpenStack的Liberty源，是需要自己设置，也可以通过安装包来实现自动添加

EPEL

yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

OpenStack liberty

yum install centos-release-openstack-liberty

更新

yum upgrade

OpenStack配置工具

yum install -y python-openstackclient openstack-utils

Keystone

创建数据库，

数据库都是通过 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';

组件安装

yum install openstack-keystone httpd mod_wsgi

memcached python-memcached

配置

编辑 /etc/keystone/keystone.conf

手工修改很麻烦，红帽提供工具修改

openstack-config --set /etc/keystone/keystone.conf DEFAULT admin_token ADMIN

openstack-config --set /etc/keystone/keystone.conf database connection mysql://keystone:keystone@controller/keystone

openstack-config --set /etc/keystone/keystone.conf memcache servers localhost:11211

openstack-config --set /etc/keystone/keystone.conf token provider uuid

openstack-config --set /etc/keystone/keystone.conf token driver memcache

openstack-config --set /etc/keystone/keystone.conf revoke driver sql

配置Apache

sed -i "s/#ServerName www.example.com:80/ServerName controller/" /etc/httpd/conf/httpd.conf

创建apache启动的配置文件

cat > /etc/httpd/conf.d/wsgi-keystone.conf << OFF

Listen 5000

Listen 35357

WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

</VirtualHost>

OFF

启动服务

systemctl enable memcached.service

systemctl start memcached.service

systemctl enable httpd.service

systemctl start httpd.service

初始化数据库

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

你会看到提示 No handlers could be found for logger “oslo_config.cfg”

忽略就可以。不能直接使用keystone-manage db_sync，会导致日志权限出错。

服务和Endpoint

文档把public，internal和admin 3种网络都使用一个网段

设置临时环境变量

export OS_TOKEN=ADMIN

export OS_URL=http://controller:35357/v3

export OS_IDENTITY_API_VERSION=3

下面的命令就一行一行执行

openstack service create --name keystone --description "OpenStack Identity" identity

openstack endpoint create --region RegionOne identity public http://controller:5000/v2.0

openstack endpoint create --region RegionOne identity internal http://controller:5000/v2.0

openstack endpoint create --region RegionOne identity admin http://controller:35357/v2.0

openstack project create --domain default --description "Admin Project" admin

openstack user create admin --domain default --password admin

openstack role create admin

openstack role add --project admin --user admin admin

openstack project create --domain default --description "Service Project" service

openstack project create --domain default --description "Demo Project" demo

openstack user create demo --domain default --password demo

openstack role create user

openstack role add --project demo --user demo user

检测设置

删除临时环境变量

unset OS_TOKEN OS_URL

设置环境

cat > /root/admin-openrc.sh << OFF

export OS_PROJECT_DOMAIN_ID=default

export OS_USER_DOMAIN_ID=default

export OS_PROJECT_NAME=admin

export OS_TENANT_NAME=admin

export OS_USERNAME=admin

export OS_PASSWORD=admin

export OS_AUTH_URL=http://controller:35357/v3

export OS_IDENTITY_API_VERSION=3

export OS_TENANT_NAME=demo

export OS_USERNAME=demo

export OS_PASSWORD=demo

export OS_AUTH_URL=http://controller:5000/v3

export OS_IDENTITY_API_VERSION=3

OFF

Glance组件

OpenStack各个组件的安装，其实步骤都差不多，多装几次，就知道规律

创建数据库

CREATE DATABASE glance;

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'glance';

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance';

exit;

服务和Endpoint

设置环境变量

source admin-openrc.sh

在keystone里，创建glance镜像服务，并且创建相关Endpoint

openstack user create glance --domain default --password glance

openstack role add --project service --user glance admin

openstack service create --name glance --description "OpenStack Image service" image

openstack endpoint create --region RegionOne image public http://controller:9292

openstack endpoint create --region RegionOne image internal http://controller:9292

openstack endpoint create --region RegionOne image admin http://controller:9292

组件安装

yum install openstack-glance python-glance python-glanceclient

配置

修改 /etc/glance/glance-api.conf

openstack-config --set /etc/glance/glance-api.conf database connection mysql://glance:glance@controller/glance

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_uri http://controller:5000

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://controller:35357

openstack-config --set /etc/glance/glance-api.conf DEFAULT notification_driver noop

openstack-config --set /etc/glance/glance-api.conf DEFAULT verbose True

修改 /etc/glance/glance-registry.conf

openstack-config --set /etc/glance/glance-registry.conf database connection mysql://glance:glance@controller/glance

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_uri http://controller:5000

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_url http://controller:35357

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_plugin password

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_domain_id default

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken user_domain_id default

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_name service

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken username glance

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken password glance

openstack-config --set /etc/glance/glance-registry.conf paste_deploy flavor keystone

openstack-config --set /etc/glance/glance-registry.conf DEFAULT notification_driver noop

openstack-config --set /etc/glance/glance-registry.conf DEFAULT verbose True

初始化数据库

su -s /bin/sh -c "glance-manage db_sync" glance

你可以遇到No handlers could be found for logger “oslo_config.cfg”

提示，忽略就可以。你可以登录mysql，会发现glance的表都已经创建好了。

启动服务

systemctl enable openstack-glance-api.service openstack-glance-registry.service

systemctl start openstack-glance-api.service openstack-glance-registry.service

验证

在环境变量增加glance的API版本

echo "export OS_IMAGE_API_VERSION=2"

| tee -a admin-openrc.sh demo-openrc.sh

重新运行

source admin-openrc.sh

下载镜像

wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

上传镜像

glance image-create --name "cirros" --file /root/cirros-0.3.4-x86_64-disk.img

--disk-format qcow2 --container-format bare --visibility public --progress

查看镜像
