三节点搭建openstack-Mitaka版本

前言：

　　现在的云计算平台已经非常火，也非常的稳定了。像阿里云平台，百度云平台等等，今天咱们基于openstack来搭建一个云平台

注意：

　　本次平台搭建为三节点搭建（没有外部存储节点，所有存储为本地存储的方式）

一：网络：

　　1.管理网络：192.168.1.0/24

　　2.数据网络：1.1.1.0/24

二：操作系统

　　CentOS Linux release 7.3.1611 (Core) 

三：内核

　　3.10.0-514.el7.x86_64

四：版本信息：

　　openstack版本mitaka

注意:

　　在修改配置文件的时候 一定要注意不要再某条配置文件后面添加注释。可以上面与下面

　　相关配置一定要在标题的后追加，不要再原有的基础上修改

效果图：

　　

本博客主要是搭建前期的环境，后续的一些内部操作将会在后面的博客中陆续更新

准备环境:

　　为三台主机添加hosts解析文件，为每台机器设置主机名，关闭firewalld，sellinux，设置静态IP

　　为计算节点添加两块网卡，为网络节点添加两块网卡

　　

　　自定义yum源

 　  所有节点执行：

　　　　yum makecache && yum install vim net-tools -y&& yum update -y

 　　　  关闭yum自动更新

　　　　修改/ect/yum/yum-cron.conf将download_updates = yes改为no即可

　　

　　也可以使用网络yum源： 

　　下载网络yum源（在所有节点执行）

　　　　yum install centos-release-openstack-mitaka -y

 　　　　制作yum缓存并更新系统

　　预装包（在所有节点执行）

　　　　yum install python-openstackclient -y

　　　　yum install openstack-selinux -y

　　部署时间服务（在所有节点执行）

　　　　yum install chrony -y 

控制节点：

    修改配置：

    /etc/chrony.conf

    server ntp.staging.kycloud.lan iburst

    allow 192.168.1.0/24

启动服务：

    systemctl enable chronyd.service

    systemctl start chronyd.service

其余节点：

　　

    修改配置：

    /etc/chrony.conf

    server 192.168.1.142 iburst

启动服务

    systemctl enable chronyd.service

    systemctl start chronyd.service

验证：

    每台机器执行：

    chronyc sources

    在S那一列包含*号，代表同步成功（可能需要花费几分钟去同步，时间务必同步）

控制节点操作

安装数据库

　　yum install mariadb mariadb-server python2-PyMySQL -y

编辑：
/etc/my.cnf.d/openstack.cnf[mysqld]
bind-address = 192.168.1.142#控制节点IP
default-storage-engine = innodb
innodb_file_per_table
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

启动服务
systemctl enable mariadb.service
systemctl start mariadb.service

　　

安装mogodb

　　yum install mongodb-server mongodb -y

 

 

编辑：/etc/mongod.confbind_ip = 192.168.1.142
smallfiles = true

 

保存退出后启动服务 并添加开机自启动
systemctl enable mongod.service
systemctl start mongod.service

 

部署消息列队
　　yum install rabbitmq-server -y

启动服务并开机自启
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

新建rabbitmq用户名与密码(这里面我所有的密码都用lhc001)
rabbitmqctl add_user openstack lhc001

为新建的用户openstack设定权限：
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

安装memcache缓存token
　　yum install memcached python-memcached -y

启动并添加到开机自启动
systemctl enable memcached.service
systemctl start memcached.service

 

部署keystone服务

对数据库的操作
CREATE DATABASE keystone;

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' 
IDENTIFIED BY 'lhc001';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' 
IDENTIFIED BY 'lhc001';

GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'controller01' 
IDENTIFIED BY 'lhc001';
#远程登录的要写上这个不然会报错
  
flush privileges;

安装keystone
　　yum install openstack-keystone httpd mod_wsgi -y

 

编辑/etc/keystone/keystone.conf
[DEFAULT]
admin_token = lhc001 

[database]
connection = mysql+pymysql://keystone:lhc001@controller01/keystone

[token]
provider = fernet    

 

同步修改数据到数据库中
　　su -s /bin/sh -c "keystone-manage db_sync" keystone

初始化fernet keys
　　keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

配置apache服务

编辑：/etc/httpd/conf/httpd.conf
ServerName controller01

硬链接/usr/share/keystone/wsgi-keystone.conf到/etc/httpd/conf.d/下

ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/wsgi-keystone.conf

重新启动httpd

systemctl restart httpd

创建服务实体和访问站点

实现配置管理员环境变量，用于获取后面创建的权限
export OS_TOKEN=lhc001
export OS_URL=http://controller01:35357/v3
export OS_IDENTITY_API_VERSION=3    

基于上一步给的权限，创建认证服务实体（目录服务）

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

基于上一步建立的服务实体，创建访问该实体的三个api端点

openstack endpoint create --region RegionOne 
  identity public http://controller01:5000/v3
  
openstack endpoint create --region RegionOne 
  identity internal http://controller01:5000/v3
  
openstack endpoint create --region RegionOne 
  identity admin http://controller01:35357/v3    
    

 

 创建域，租户，用户，角色，把四个元素关联到一起

 建立一个公共的域名： 

openstack domain create --description "Default Domain" default    

管理员：admin
openstack project create --domain default 
  --description "Admin Project" admin
  
openstack user create --domain default 
  --password-prompt admin
 
openstack role create admin

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

普通用户：demo
openstack project create --domain default 
  --description "Demo Project" demo
  
openstack user create --domain default 
  --password-prompt demo
 
openstack role create user

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

为后续的服务创建统一租户service
openstack project create --domain default 
  --description "Service Project" service

验证关联

验证操作

编辑：/etc/keystone/keystone-paste.ini
在[pipeline:public_api], [pipeline:admin_api], and [pipeline:api_v3] 三个地方
移走：admin_token_auth 

新建客户端脚本文件

管理员：admin-openrc

export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=lhc001
export OS_AUTH_URL=http://controller01:35357/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

普通用户demo：demo-openrc

export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=demo
export OS_USERNAME=demo
export OS_PASSWORD=lhc001
export OS_AUTH_URL=http://controller01:5000/v3
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

退出控制台 重新登录
source admin-openrc
openstack token issue

部署镜像服务 

数据库操作 

mysql -u root -p
CREATE DATABASE glance;

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' 
IDENTIFIED BY 'lhc001';

GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' 
  IDENTIFIED BY 'lhc001';
  
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'controller01' 
  IDENTIFIED BY 'lhc001';
#同上面keystone对数据库的操作一样
flush privileges;

keystone认证操作：
上面提到过：所有后续项目的部署都统一放到一个租户service里，然后需要为每个项目建立用户，建管理员角色，建立关联

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

 

关联角色

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

建立服务实体
openstack service create --name glance 
  --description "OpenStack Image" image

建端点
openstack endpoint create --region RegionOne 
  image public http://controller01:9292
  

openstack endpoint create --region RegionOne 
  image internal http://controller01:9292
 
openstack endpoint create --region RegionOne 
  image admin http://controller01:9292

安装glance软件
　　yum install openstack-glance -y

这次的环境统一都是用本地存储，但是无论什么存储，都要在启动glance之前建立，不然启动时glance搜索不到，虽然不会报错，但是对于后面的一些操作会报错。所以为了省略麻烦 还是先提前建立好

mkdir /var/lib/glance/images/
chown glance. /var/lib/glance/images/

 

编辑/etc/glance/glacne-api.conf

　[database]
　connection = mysql+pymysql://glance:lhc001@controller01/glance

[keystone_authtoken]
auth_url = http://controller01:5000
memcached_servers = controller01:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = glance
password = lhc001

[paste_deploy]
flavor = keystone

[glance_store]
stores = file,http
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

编辑/etc/glance/glacne-registry

这里的registry配置的数据库是用来检索镜像元数据用的
[database]
connection = mysql+pymysql://glance:lhc001@controller01/glance

在之前的版本中，glance-api怎么配置registry就怎么配置。现在变成了v3版本 就不需要那么繁琐，直接在glance-registry中添加一条数据库接口，其它一概不用

同步数据库：输出不是报错
su -s /bin/sh -c "glance-manage db_sync" glance

 

启动并添加到开机自启动
systemctl enable openstack-glance-api.service 
  openstack-glance-registry.service
systemctl start openstack-glance-api.service 
  openstack-glance-registry.service

验证操作

查看openstack image list 输出为空
然后执行镜像上传
openstack image create "cirros" 
  --file cirros-0.3.4-x86_64-disk.img 
  --disk-format qcow2 --container-format bare 
  --public

 部署compute服务

再部署任何组件时都有对keystone的数据库中进行添加用户的操作，即所有组件共用一个数据库服务

compute对数据库的操作
CREATE DATABASE nova_api;

CREATE DATABASE nova;

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' 
  IDENTIFIED BY 'lhc001';
  
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' 
  IDENTIFIED BY 'lhc001';

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'controller01' 
  IDENTIFIED BY 'lhc001';
  
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' 
  IDENTIFIED BY 'lhc001';
  
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' 
  IDENTIFIED BY 'lhc001';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'controller01' 
  IDENTIFIED BY 'lhc001';

flush privileges;

keystone部分的相关操作

openstack user create --domain default 
  --password-prompt nova
创建一个nova用户 输入用户名密码 
 
openstack role add --project service --user nova admin
用户与角色项目关联

openstack service create --name nova 
  --description "OpenStack Compute" compute
 创建实体

openstack endpoint create --region RegionOne 
  compute public http://controller01:8774/v2.1/%(tenant_id)s
  
openstack endpoint create --region RegionOne 
  compute internal http://controller01:8774/v2.1/%(tenant_id)s
  
openstack endpoint create --region RegionOne 
  compute admin http://controller01:8774/v2.1/%(tenant_id)s  

  三个endpoint 

安装软件包：

yum install openstack-nova-api openstack-nova-conductor

  openstack-nova-console openstack-nova-novncproxy

  openstack-nova-scheduler -y

编辑/etc/nova/nova.conf

[DEFAULT]

#下面的为管理ip
vncserver_proxyclient_address = 192.168.1.142 

[oslo_concurrency]
lock_path = /var/lib/nova/tmp  

同步数据库 有输出不是报错

su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage db sync" nova

启动并添加到开机自启动
systemctl enable openstack-nova-api.service 
  openstack-nova-consoleauth.service openstack-nova-scheduler.service 
  openstack-nova-conductor.service openstack-nova-novncproxy.service
systemctl start openstack-nova-api.service 
  openstack-nova-consoleauth.service openstack-nova-scheduler.service 
  openstack-nova-conductor.service openstack-nova-novncproxy.service

 接下来就要配置计算节点了 控制节点就暂时先放一放

配置计算节点 

安装软件包：
yum install openstack-nova-compute libvirt-daemon-lxc -y

修改配置：
编辑/etc/nova/nova.conf

[DEFAULT]
rpc_backend = rabbit

[glance]
api_servers = http://controller01:9292

[oslo_concurrency]
lock_path = /var/lib/nova/tmp

启动程序

systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service

 验证操作：

 控制节点测试

网络部署 

还是在控制节点进行数据库操作

CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' 
  IDENTIFIED BY 'lhc001';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' 
  IDENTIFIED BY 'lhc001';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'controller01' 
  IDENTIFIED BY 'lhc001';  
flush privileges;

keystone对于neutron的操作

创建用户建立关联
openstack user create --domain default --password-prompt neutron
openstack role add --project service --user neutron admin

 创建实体服务与三个endpoint

openstack service create --name neutron 
  --description "OpenStack Networking" network


openstack endpoint create --region RegionOne 
  network public http://controller01:9696
  
openstack endpoint create --region RegionOne

 数据库同步：会有输出 并不是报错

su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf 
 --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron

 重新启动nova

　　 systemctl restart openstack-nova-api.service

启动neutron并加入到开机自启
　　systemctl enable neutron-server.service
　　systemctl start neutron-server.service

配置网络节点

编辑 /etc/sysctl.conf
net.ipv4.ip_forward=1
net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

执行下列命令，立即生效
　　sysctl -p

enable_isolated_metadata=True

配置元数据代理。编辑 /etc/neutron/metadata_agent.ini文件

[DEFAULT]
nova_metadata_ip=controller01
metadata_proxy_shared_secret=lhc001

启动服务
网路节点：

systemctl enable neutron-openvswitch-agent.service neutron-l3-agent.service
neutron-dhcp-agent.service neutron-metadata-agent.service

systemctl start neutron-openvswitch-agent.service neutron-l3-agent.service
neutron-dhcp-agent.service neutron-metadata-agent.service

注意上面标红的服务，在查看服务状态的时候ovs会提示启动失败，这个不用担心，因为之前上面的配置文件中配置的数据管理IP与网桥都没有创建，它的log中提示找不到，没关系 后面会创建出来。

创建为网络节点数据网络ip

[root@network01 network-scripts]# cat ifcfg-ens37 
TYPE="Ethernet"
BOOTPROTO="static"
IPADDR=1.1.1.119
NETMASK=255.255.255.0
NAME="ens37"
DEVICE="ens37"
ONBOOT="yes"

计算节点也是一样，也要创建一个数据管理IP

cd /etc/sysconfig/network-scripts
cp ifcfg-ens33 ifcfg-ens37

[root@compute01 network-scripts]# cat ifcfg-ens37 
TYPE="Ethernet"
BOOTPROTO="static"
IPADDR=1.1.1.117
NETMASK=255.255.255.0
NAME="ens37"
DEVICE="ens37"
ONBOOT="yes"

重启两节点网卡服务

　　systemctl restart nwtwork

两节点互ping 测试

回到网络节点上创建网桥

建立网桥，br-ex网卡与外部网卡绑定，由于在实验之前 我们添加了三块网卡，但是我这台机器上能上网的只有一个IP地址，所以能用的网络就两个一个数据网络，一个管理网络，但是在真实环境中，是一定要用三块网卡的

cp ifcfg-ens33 ifcfg-br-ex

[root@network01 network-scripts]# cat ifcfg-br-ex 
TYPE="Ethernet"
BOOTPROTO="static"
IPADDR=192.168.1.140
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=192.168.1.1
NAME="br-ex"
DEVICE="br-ex"
ONBOOT="yes"
NM_CONTROLLED=no    #这个一定要添加不然网桥会建立失败

同理，既然已经将网桥建立了，那么ens33上面的IP地址就要拿掉

[root@network01 network-scripts]# cat ifcfg-ens33
TYPE="Ethernet"
BOOTPROTO="static"
DEFROUTE="yes"
PEERDNS="yes"
PEERROUTES="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_PEERDNS="yes"
IPV6_PEERROUTES="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="e82bc9e4-d28e-4363-aab4-89fda28da938"
DEVICE="ens33"
ONBOOT="yes" 
NM_CONTROLLED=no      #在真实网卡上也要添加

重启网络节点网卡

　　systemctl restart nwtwork

这时候再次查看ovs服务的状态（

systemctl status neutron-openvswitch-agent.service）就发现这个服务一定running了

到这里网络节点就告一段落了

配置计算节点

编辑 /etc/sysctl.conf

net.ipv4.conf.all.rp_filter=0
net.ipv4.conf.default.rp_filter=0

sysctl -p

计算节点安装ovs等组件
　　yum install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch -y

ok，接下来的事情就简单多了，在控制节点部署一个dashboard服务

控制节点操作

安装软件包
　　yum install openstack-dashboard -y

配置/etc/openstack-dashboard/local_settings
