OpenStack Rocky 版本部署之七——计算节点

第二部 OpenStack Rocky计算节点配置

一、基础环境

关防火墙，关selinux，永久修改主机名

#查看服务器是否支持虚拟化

# egrep -c '(vmx|svm)' /proc/cpuinfo

返回值为非0，支持虚拟化

为0，打开虚拟机如图内容

1、配置yum源

查看OpenStack Rocky 版本部署之一——基础环境配置

2、安装基础软件

# yum clean all && yum repolist

# yum install python-openstackclient -y

# yum install openstack-selinux -y

# yum -y install libibverbs

3、安装OpenStack应用组件

（1）安装网络服务软件包

#ipset是iptables的扩展,它允许你创建匹配安全组的规则。

# yum install openstack-neutron-linuxbridge ebtables ipset -y

（2）安装nova的软件包:

# yum install openstack-nova-compute -y

二、网络服务neutron

1、修改neutron配置文件

（1）编辑/etc/neutron/neutron.conf配置文件:

[DEFAULT]

transport_url = rabbit://openstack:openstack@controller

auth_strategy = keystone

[keystone_authtoken]

www_authenticate_uri = http://controller:5000

auth_url = http://controller:http://

memcached_servers = controller:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = neutron

password = neutron

[oslo_concurrency]

lock_path = /var/lib/neutron/tmp

（2）配置Linux bridge客户端

# 编辑 /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge]

physical_interface_mappings = public:ens33

[vxlan]

enable_vxlan = false

[securitygroup]

enable_security_group = true

firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver

（3）配置sysctl.conf

net.bridge.bridge-nf-call-iptables = 1

net.bridge.bridge-nf-call-ip6tables = 1

2、启动服务并设置开机自启

# systemctl enable neutron-linuxbridge-agent.service

# systemctl start neutron-linuxbridge-agent.service

三、计算服务nova

1、修改nova配置文件

（1）修改/etc/nova/nova.conf

[DEFAULT]

enabled_apis = osapi_compute,metadata

transport_url = rabbit://openstack:openstack@controller

use_neutron = True

firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api]

auth_strategy = keystone

[keystone_authtoken]

auth_url = http://controller:http://

memcached_servers = controller:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = nova

password = nova

#server_proxyclient_address参数代理的地址会将数据发送给novncproxy_base_url参数地址

[vnc]

enabled = True

server_listen = 0.0.0.0

server_proxyclient_address = compute

novncproxy_base_url = http://controller:6080/vnc_auto.html

[glance]

api_servers = http://controller:9292

[oslo_concurrency]

lock_path = /var/lib/nova/tmp

[placement]

os_region_name = RegionOne

project_domain_name = Default

project_name = service

auth_type = password

user_domain_name = Default

auth_url = http://controllerhttp://

username = placement

password = placement

[neutron]

url = http://controllerhttp://

auth_url = http://controllerhttp://

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = neutron

password = neutron

#虚拟化格式使用qemu，对机器消耗较小，其他虚拟化格式还有：kvm，lxc，qemu，uml， xen ，parallels

[libvirt]

virt_type = qemu

2、设置开机自启并启动服务

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

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

3、在控制节点上查看

# openstack network agent list

 

# openstack compute service list

 

四、错误整理

1、如果报以下错误。

 

执行下面命令

# modprobe br_netfilter
