版本centos7.2  openstack版本newton

使用两个节点controller与computer

ip地址为192.168.109.7与192.168.109.6

1.准备工作

关闭防火墙

# systemctl stop firewalld.service 

# systemctl disable firewalld.service 


关闭selinux

#vi /etc/selinux/config

将SELINUX改为disabled

/usr/sbin/sestatus -v 重启后查看状态


安装常用命令

# yum install net-tools wget vim ntpdate bash-completion -y


添加源

#cd /etc/yum.repos.d

#rm -rf *

#  wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

#  wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo


更改hostname

#hostnamectl set-hostname controller


配置hosts

#vim /etc/hosts

192.168.109.7 controller


NTP同步时间

 #ntpdate cn.pool.ntp.org 

#date 查看时间


2.安装mariadb

安装数据库

 # yum install mariadb mariadb-server python2-PyMySQL


创建并编辑配置mariadb

#vim /etc/my.cnf.d/mariadb-openstack.cnf

在[mysqld]区块添加如下内容

[mysqld]

default-storage-engine = innodb 

innodb_file_per_table 

collation-server = utf8_general_ci 

init-connect = 'SET NAMES utf8' 

character-set-server = utf8 

bind-address=192.168.109.7


启动数据库并设置开机启动

#systemctl enable mariadb.service

#systemctl restart mariadb.service

#systemctl status mariadb.service

#systemctl list-unit-files | grep mariadb.service


设置密码

mysql_secure_installation


3.安装RabbitMQ

每个节点都安装erlang

#yum install -y erlang


每个节点安装RabbitMQ

#yum install -y rabbitmq-server


每个节点都启动rabbitmq并设置开机启动

#systemctl enable rabbitmq-server.service

#systemctl restart rabbitmq-server.service

#systemctl status rabbitmq-server.service

#systemctl list-unit-files | grep rabbitmq-server.service


创建openstack

#rabbitmqctl add_user openstack bgops098


赋予权限

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

# rabbitmqctl set_user_tags openstack administrator 

# rabbitmqctl list_users




查看端口是否是5672

#netstat -ntlp | grep 5672


查看rabbitmq插件

# /usr/lib/rabbitmq/bin/rabbitmq-plugins list


打开相关插件

# /usr/lib/rabbitmq/bin/rabbitmq-plugins enable rabbitmq_management mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent


重启服务

#systemctl restart rabbitmq-server


查看状态 端口号15672 默认密码guest/guest 也可以用openstack/bgops098

openstack安装


(相关命令，非必须）创建用户

# rabbitmqctl add_user mqadmin mqadmin 

# rabbitmqctl set_user_tags mqadmin administrator 

# rabbitmqctl set_permissions -p / mqadmin ".*" ".*" ".*"

更改密码

# rabbitmqctl change_password guest bgops098 



3.安装keystone

配置源

cd /etc/yum.repos.d

vim openstack.repo

添加

[openstack] 

name=newton 

baseurl= http://mirror.centos.org/centos/7/cloud/x86_64/openstack-newton/ 

enabled=1 

gpgcheck=0


创建keystone数据库

#mysql -u  root -p

# CREATE DATABASE keystone;


创建用户赋予权限

 #GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'bgops098'; 

# GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'bgops098';


安装keystone和memcached

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


启动memcached

# systemctl enable memcached.service 

# systemctl restart memcached.service 

# systemctl status memcached.service


配置/etc/keystone/keystone.conf文件

# openssl rand -hex 10                首先需要先产生一个随机数，用作初始配置时的管理员令牌 

# ADMIN_TOKEN=929c32c35c315b694536                这个字符串就是上面openssl随机生成的 

# cp /etc/keystone/keystone.conf /etc/keystone/keystone.conf.bak 

# >/etc/keystone/keystone.conf 

# openstack-config --set  /etc/keystone/keystone.conf DEFAULT debug false 

# openstack-config --set  /etc/keystone/keystone.conf DEFAULT verbose true 

# openstack-config --set  /etc/keystone/keystone.conf DEFAULT admin_token 929c32c35c315b694536 

# openstack-config --set  /etc/keystone/keystone.conf DEFAULT admin_endpoint http://controller:35357 

# openstack-config --set  /etc/keystone/keystone.conf DEFAULT public_endpoint http://controller:5000 

# openstack-config --set  /etc/keystone/keystone.conf database connection mysql://keystone:bgops098@controller/keystone

# openstack-config --set  /etc/keystone/keystone.conf oslo_messaging_rabbit rabbit_host controller 

# openstack-config --set  /etc/keystone/keystone.conf oslo_messaging_rabbit rabbit_port 5672 

# openstack-config --set  /etc/keystone/keystone.conf oslo_messaging_rabbit rabbit_userid openstack 

# openstack-config --set  /etc/keystone/keystone.conf oslo_messaging_rabbit rabbit_password bgops098

# openstack-config --set  /etc/keystone/keystone.conf cache backend oslo_cache.memcache_pool 

# openstack-config --set  /etc/keystone/keystone.conf cache enabled true 

# openstack-config --set  /etc/keystone/keystone.conf cache memcache_servers controller:11211 

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

# openstack-config --set  /etc/keystone/keystone.conf token expiration 3600 

# openstack-config --set  /etc/keystone/keystone.conf token provider fernet


配置httpd.conf和memcached

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

# sed -i  's/OPTIONS*.*/OPTIONS="-l 127.0.0.1,::1,192.168.109.7"/' /etc/sysconfig/memcached


配置keystone

创建文件

vim /etc/httpd/conf.d/wsgi-keystone.conf

Listen 5000
Listen 35357

    WSGIApplicationGroup %{GLOBAL}
    WSGIPassAuthorization On
    ErrorLogFormat "%{cu}t %M"
    ErrorLog /var/log/httpd/keystone-error.log
    CustomLog /var/log/httpd/keystone-access.log combined


    <Directory /usr/bin>
        Require all granted
    </Directory>

# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone


启动httpd

systemctl enable httpd.service

systemctl restart httpd.service

systemctl status httpd.service

systemctl list-unit-files | grep httpd.service


创建admin用户

# keystone-manage bootstrap \ 

 --bootstrap-password bgops098 \ 

 --bootstrap-username admin \ 

--bootstrap-project-name admin \ 

 --bootstrap-role-name admin \

 --bootstrap-admin-url http://controller:35357/v3 \ 

--bootstrap-internal-url http://controller:35357/v3 \ 

  --bootstrap-public-url http://controller:5000/v3 


验证

# openstack project list --os-username admin --os-project-name admin --os-user-domain-id default --os-project-domain-id  default --os-identity-api-version 3 --os-auth-url http://controller:5000 --os-password bgops098

openstack安装

创建admin用户环境变量

# vim /root/admin-openrc 

export OS_USER_DOMAIN_ID=default 

export OS_PROJECT_DOMAIN_ID=default 

export OS_USERNAME=admin

export OS_PROJECT_NAME=admin 

export OS_PASSWORD=bgops098

export OS_IDENTITY_API_VERSION=3 

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


创建service项目

# source /root/admin-openrc 

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

openstack安装

创建demo项目

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

# openstack user create --domain default  demo  --password bgops098

openstack安装

创建user角色将demo用户赋予user角色 

# openstack role create user 

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


验证

# unset OS_TOKEN OS_URL 

# openstack --os-auth-url http://controller:35357/v3  --os-project-domain-name default --os-user-domain-name default   --os-project-name admin --os-username admin token issue --os-password bgops098
