文章目录

很多文章都是devstack安装的allinone，我这里使用源码组件手动安装。

环境准备

Environment
这里需要先配置一些环境。
首先我这里是虚拟机安装的系统，可能设置的密码不是当前用户的root密码，反正就得重置一下
执行下面的命令，然后输入安装系统设置的密码，之后就可以了。
sudo passwd root
其实这里好像还需要关闭防火墙以及selinux，但是这系统直接没装，就省事了。

换源

需要先换一个源，方便下载
换阿里源
gedit /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse 
deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

然后更新一下元数据，如果用upgrade会直接升级对应的包
sudo apt-get update

网络配置

首先得关闭NetworkManager，不然设置的静态IP不行，这个会和interfaces冲突，如果都存在默认使用前者管理网络。
NetworkManager好像在/etc/netplan/xxX里面配置。

systemctl stop NetworkManager
systemctl disable NetworkManager

然后再配置一下ip转发
修改文件/etc/sysctl.conf

net.ipv4.ip_forward=1	//取消注释

执行sysctl -p保存

静态IP

需要配置一下网络，改为桥接的方式，设置静态IP
interfaces使用的配置文件是/etc/network/interfaces，修改如下

auto lo
iface lo inet loopback

# The primary network interface

auto ens33
iface ens33 inet static
address 192.168.1.210
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1

然后在/etc/resolv.conf里面可以配置DNS，但是在这里配置好像是临时的，重启就失效了

nameserver 114.114.114.114

随后重启网络systemctl restart networking
现在就可以ping通百度了。

桥接

实际应用的时候，我发现好像桥接比较好，通过一个网桥来连接到物理网卡
一个简单的配置，manual表示设置一个空的，一般用于配置网桥，static表示静态IP

auto lo
iface lo inet loopback

# The primary network interface

auto ens33
iface ens33 inet manual

# inside bridge network port

auto br-mgmt
iface br-mgmt inet static
	address 192.168.1.210
	#network 192.168.1.0
	netmask 255.255.255.0
	#broadcast 192.168.1.255
	gateway 192.168.1.1

	# set static route for LAN
	#post-up route add -net 10.0.0.0 netmask 255.0.0.0 gw 10.18.44.1
	#post-up route add -net 161.26.0.0 netmask 255.255.0.0 gw 10.18.44.1
	bridge_ports ens33
	bridge_stp off
	bridge_fd 0

对于多个网桥的绑定好像也是可以的。
如果有多个网桥的话，最好只给这个外网的网桥配置一个网关，如果都配置可能会报错

auto lo
iface lo inet loopback

# The primary network interface

auto ens33
iface ens33 inet manual

# inside bridge network port

auto br-ens33
iface br-ens33 inet static
	address 192.168.1.210
	#network 192.168.1.0
	netmask 255.255.255.0
	#broadcast 192.168.1.255
	gateway 192.168.1.1

	# set static route for LAN
	#post-up route add -net 10.0.0.0 netmask 255.0.0.0 gw 10.18.44.1
	#post-up route add -net 161.26.0.0 netmask 255.255.0.0 gw 10.18.44.1
	bridge_ports ens33
	bridge_stp off
	bridge_fd 1
	

auto br-mgmt
iface br-mgmt inet static
	address 10.17.23.10
	netmask 255.255.255.0

	# set static route for LAN
	#post-up route add -net 10.0.0.0 netmask 255.0.0.0 gw 10.18.44.1
	#post-up route add -net 161.26.0.0 netmask 255.255.0.0 gw 10.18.44.1
	bridge_ports ens33
	bridge_stp off
	bridge_fd 1

完事以后直接重启网络服务可能会报错？反正我这给他重启主机了

永久修改DNS

修改文件/etc/systemd/resolvd.conf
取消里面DNS的注释，填写相应的就可以了

主机名

修改host文件
/etc/hosts以及/etc/hostname文件
我忘了怎么生效了，直接重启reboot吧

基础服务

时间服务

Network Time Protocol (NTP)
安装chrony
apt install chrony
修改文件/etc/chrony/chrony.conf，添加时钟服务器。如果是控制节点，需要让其他节点可以访问到，使用子网

#注释掉几个pool
server controller iburst

allow 10.0.0.0/8

local stratum 10

#下面是配置文件全内容

file:/etc/chrony/chrony.conf

# Welcome to the chrony configuration file. See chrony.conf(5) for more
# information about usuable directives.

# This will use (up to):
# - 4 sources from ntp.ubuntu.com which some are ipv6 enabled
# - 2 sources from 2.ubuntu.pool.ntp.org which is ipv6 enabled as well
# - 1 source from [01].ubuntu.pool.ntp.org each (ipv4 only atm)
# This means by default, up to 6 dual-stack and up to 2 additional IPv4-only
# sources will be used.
# At the same time it retains some protection against one of the entries being
# down (compare to just using one of the lines). See (LP: #1754358) for the
# discussion.
#
# About using servers from the NTP Pool Project in general see (LP: #104525).
# Approved by Ubuntu Technical Board on 2011-02-08.

server controller
allow 0.0.0.0/0

# This directive specify the location of the file containing ID/key pairs for
# NTP authentication.
keyfile /etc/chrony/chrony.keys

# This directive specify the file into which chronyd will store the rate

makestep 1 3

local stratum 10

重启服务
service chrony restart

可以通过chronyc sources验证是否配置好。
如果是^*说明配置好了，如果是？说明没有连接服务器

          RTC in local TZ: no

OpenStack软件包

OpenStack packages for Ubuntu
可以选择相应的版本进行安装。
这里使用yoga版本
add-apt-repository cloud-archive:yoga
这里安装一下客户端
apt install python3-openstackclient python3-pip

数据库

SQL database for Ubuntu
安装数据库
apt install mariadb-server python3-pymysql
然后需要创建配置文件/etc/mysql/mariadb.conf.d/99-openstack.cnf

filename:/etc/mysql/mariadb.conf.d/99-openstack.cnf

[mysqld]
bind-address = 10.17.23.10

default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

重启数据库
service mysql restart
随后配置一下密码，mysql_secure_installation

消息队列

Message queue for Ubuntu
先安装消息队列
apt install rabbitmq-server
配置一下，创建openstack用户

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

memcached

Memcached for Ubuntu
安装
apt install memcached python3-memcache -y
配置一下/etc/memcached.conf，搜索127.0.0.1替换为controller ip。
sed -i ‘s/127.0.0.1/10.17.23.10/g’ /etc/memcached.conf
然后重启service memcached restart

etcd

Etcd for Ubuntu
直接安装，apt install etcd -y
修改配置文件/etc/default/etcd，修改为自己控制节点的管理IP

ETCD_NAME="controller"
ETCD_DATA_DIR="/var/lib/etcd"
ETCD_INITIAL_CLUSTER_STATE="new"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
ETCD_INITIAL_CLUSTER="controller=http://10.17.23.10:2380"
ETCD_INITIAL_ADVERTISE_PEER_URLS="http://10.17.23.10:2380"
ETCD_ADVERTISE_CLIENT_URLS="http://10.17.23.10:2379"
ETCD_LISTEN_PEER_URLS="http://0.0.0.0:2380"
ETCD_LISTEN_CLIENT_URLS="http://10.17.23.10:2379"

可以自动化修改，这里要保证运行的路径就是这个脚本路径，不然会找不到文件

cp etcd /etc/default/etcd
sed -i "s/127.0.0.1/$controller_ip/g" /etc/default/etcd

启动服务

systemctl enable etcd
systemctl restart etcd

OpenStack

OpenStack Yoga Installation Guides
然后开始组件安装

Keystone

Keystone Installation Tutorial for Ubuntu
创建数据库

CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'openstack';

安装keystone组件

apt install keystone

顺便下载一个配置工具，方便修改配置文件openstack-utils。但是ubuntu搜不到，这个好像是centos里面的，然后搜了一下发现ubuntu里面叫crudini，这两个其实是一样的，是同一个人使用python开发的。
OpenStack配置文件的快速修改方法
那就安装一下

apt install curdini

修改配置文件/etc/keystone/keystone.conf

crudini --set /etc/keystone/keystone.conf database connection "mysql+pymysql://keystone:${password}@controller/keystone"
crudini --set /etc/keystone/keystone.conf token provider fernet

填充数据库

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

初始化令牌仓库

keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

创建管理员用户

keystone-manage bootstrap --bootstrap-password admin \
  --bootstrap-admin-url http://controller:5000/v3/ \
  --bootstrap-internal-url http://controller:5000/v3/ \
  --bootstrap-public-url http://controller:5000/v3/ \
  --bootstrap-region-id RegionOne

然后配置一下阿帕奇，添加一个ServerName

filename:/etc/apache2/apache2.conf

ServerName controller

重启apache
service apache2 restart
然后添加一个环境变量脚本，替换一下密码，就是刚才配置的

export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3

创建相应的domain、projects等

#source adminrc_keystone

openstack project create --domain default --description "Service Project" service
openstack project create --domain default --description "Demo Project" demo
openstack user create --domain default --password demo demo
openstack role create role_demo
openstack role add --project demo --user demo role_demo

最后验证一下
执行openstack token issue。

Glance

Install and configure (Ubuntu)
先创建数据库，写脚本

filename:glance_sql.sql

CREATE DATABASE glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'openstack';

导入
mysql -u root -proot < glance_sql.sql
然后source adminrc身份文件
安装

apt install glance -y

创建相应的endpoinf和user等

openstack user create --domain default --password openstack glance
openstack role add --project service --user glance admin
openstack service create --name glance --description "OpenStack Image" 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

修改配置文件/etc/glance/glance-api.conf，最后这个oslo_limit我不知道是干啥的配置，好像是连接keystone的？之前没见过这个参数

[database]
# ...
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance

[keystone_authtoken]
# ...
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = glance
password = GLANCE_PASS

[paste_deploy]
# ...
flavor = keystone

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

[oslo_limit]
auth_url = http://controller:5000
auth_type = password
user_domain_id = default
username = glance
system_scope = all
password = openstack
service_name = glance
region_name = RegionOne

关于最后这个参数字段还是没看懂是干啥的，其实可以把service_name换成什么endpoint_id
这里其实应该还有一步，是什么授予权限，给service_name，但是我还没弄

openstack role add --user MY_SERVICE --user-domain Default --system all reader

填充数据库

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

重启服务

service glance-api restart

验证可以使用cirros上传到glance测试
下载镜像，上传glance

wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
glance image-create --name "cirros" \
  --file cirros-0.4.0-x86_64-disk.img \
  --disk-format qcow2 --container-format bare \
  --visibility=public

可以使用openstack image list或者glance image-list查看镜像。

Placement

Install and configure Placement for Ubuntu
先配置数据库

filename:placement_sql.sql

CREATE DATABASE placement;
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY 'openstack';

导入数据库

mysql -u root -proot < placement_sql.sql

配置一下openstack的用户信息

source adminrc

openstack user create --domain default --password $password placement
openstack role add --project service --user placement admin
openstack service create --name placemen --description "Placement API" placement
openstack endpoint create --region $region placement public http://controller:8778
openstack endpoint create --region $region placement internal http://controller:8778
openstack endpoint create --region $region placement admin http://controller:8778

然后安装placement

apt install placement

修改配置文件/etc/placement/placement.conf

[placement_database]
# ...
connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement

[api]
# ...
auth_strategy = keystone

[keystone_authtoken]
# ...
auth_url = http://controller:5000/v3
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = placement
password = openstack

然后同步数据库

su -s /bin/sh -c "placement-manage db sync" placement

重启阿帕奇

service apache2 restart

验证

placement-status upgrade check

然后这里需要安装一个python库

pip3 install osc-placement

shell

#must source adminrc before run this script
controller_ip='10.17.23.10'
password='openstack'
region='RegionOne'
admin_password='admin'
admin_username='admin'

mysql -u root -proot < placement_sql.sql
echo 'succeed to init placement database'

openstack user create --domain default --password $password placement
openstack role add --project service --user placement admin
openstack service create --name placemen --description "Placement API" placement
openstack endpoint create --region $region placement public http://controller:8778
openstack endpoint create --region $region placement internal http://controller:8778
openstack endpoint create --region $region placement admin http://controller:8778
echo 'succeed to config placement user and endpoints in openstack'

apt install placement-api -y

crudini --set /etc/placement/placement.conf placement_database connection "mysql+pymysql://placement:${password}@controller/placement"
crudini --set /etc/placement/placement.conf api auth_strategy "keystone"

crudini --set /etc/placement/placement.conf keystone_authtoken auth_url "http://controller:5000/v3"
crudini --set /etc/placement/placement.conf keystone_authtoken memcached_servers "controller:11211"
crudini --set /etc/placement/placement.conf keystone_authtoken auth_type "password"
crudini --set /etc/placement/placement.conf keystone_authtoken project_domain_name "Default"
crudini --set /etc/placement/placement.conf keystone_authtoken user_domain_name "Default"
crudini --set /etc/placement/placement.conf keystone_authtoken project_name "service"
crudini --set /etc/placement/placement.conf keystone_authtoken username "placement"
crudini --set /etc/placement/placement.conf keystone_authtoken password $password
echo 'succeed to config placement.conf [keystone_authtoken]'

su -s /bin/sh -c "placement-manage db sync" placement
echo 'succeed to fullfill placement database'

service apache2 restart
echo 'succeed restart apache2'

Nova

这里就分为控制节点和计算节点了。
如果是allinone的模式，先执行控制节点，然后再执行计算节点

控制节点

先创建数据库并且授权

filename:nova_sql.sql

CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;

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

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

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'openstack';

然后初始化一下，创建nova的用户、服务和端点

openstack user create --domain default --password $password nova
openstack role add --project service --user nova admin
openstack service create --name nova --description "OpenStack Compute" compute

openstack endpoint create --region $region compute public http://controller:8774/v2.1
openstack endpoint create --region $region compute internal http://controller:8774/v2.1
openstack endpoint create --region $region compute admin http://controller:8774/v2.1

然后需要安装啦

apt install nova-api nova-conductor nova-novncproxy nova-scheduler

之后就是修改配置文件/etc/nova/nova.conf

[api_database]
connection = mysql+pymysql://nova:openstack@controller/nova_api

[database]
connection = mysql+pymysql://nova:openstack@controller/nova

[DEFAULT]
transport_url = rabbit://openstack:openstack@controller:5672/

[api]
auth_strategy = keystone

[keystone_authtoken]

memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova
password = openstack

[DEFAULT]
my_ip = $my_ip

[vnc]
enabled = true
server_listen = $my_ip
server_proxyclient_address = $my_ip

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

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

[placement]
region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = openstack

然后同步数据库

su -s /bin/sh -c "nova-manage api_db sync" nova
su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
su -s /bin/sh -c "nova-manage db sync" nova

验证一下

su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

重启服务

service nova-api restart
service nova-scheduler restart
service nova-conductor restart
service nova-novncproxy restart

计算节点

先安装nova-compute

apt install nova-compute

然后修改配置文件/etc/nova/nova.conf

[DEFAULT]
transport_url = rabbit://openstack:openstack@controller

[api]
auth_strategy = keystone

[keystone_authtoken]
www_authenticate_uri = http://controller:5000/

password = openstack

[DEFAULT]
my_ip = $my_ip

[vnc]

project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = openstack

修改配置文件/etc/nova/nova-compute.conf

[libvirt]
virt_type = qemu

重启nova-compute服务

service nova-compute restart
控制节点注册计算节点

然后需要在控制节点注册一下
切到控制节点
查看一下服务，如果是up就好了
第一次我这里还出错了，我把配置文件里面的一个ip没有写，结果就是down

openstack compute service list --service nova-compute

发现计算节点

su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
shell
#must source adminrc before run this script

Cinder

这里如果需要装cinder的话，得先弄好一个硬盘，这就分物理机和虚拟机了。

Neutron

Install and configure for Ubuntu
同样分为控制节点和网络节点

控制节点

创建数据库

CREATE DATABASE neutron;
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY 'openstack';
GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY 'openstack';

新创建neutron的openstack user、service和endpoint

openstack user create --domain default --password openstack neutron
openstack role add --project service --user neutron admin
openstack service create --name neutron \
  --description "OpenStack Networking" network
openstack endpoint create --region RegionOne \
  network public http://controller:9696
openstack endpoint create --region RegionOne \
  network internal http://controller:9696
openstack endpoint create --region RegionOne \
  network admin http://controller:9696

然后这里选择创建自服务服务网络
Networking Option 2: Self-service networks
安装软件

apt install neutron-server neutron-plugin-ml2 \
  neutron-linuxbridge-agent neutron-l3-agent neutron-dhcp-agent \
  neutron-metadata-agent

修改配置文件/etc/neutron/neutron.conf

[ml2_type_flat]
flat_networks = provider

[ml2_type_vxlan]
vni_ranges = 1:1000

[securitygroup]

filename:/etc/neutron/dhcp_agent.ini

[DEFAULT]
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = true

修改配置文件/etc/neutron/metadata_agent.ini
这里的secret随便设置一个，需要和后面nova.conf的neutron里面的一致

filename:/etc/neutron/metadata_agent.ini

[DEFAULT]
nova_metadata_host = controller
metadata_proxy_shared_secret = openstack

修改配置文件/etc/nova/nova.conf
这里面的secret需要和上面保持一致

[neutron]
# ...
auth_url = http://controller:5000
auth_type = password
project_domain_name = Default
user_domain_name = Default
region_name = RegionOne
project_name = service
username = neutron
password = openstack
service_metadata_proxy = true
metadata_proxy_shared_secret = openstack

填充同步neutron的数据库

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

重启服务
