  • A06. openstack架构实战-计算机节点安装nova服务

    在计算节点上安装和配置Compute服务。该服务支持多个虚拟机管理程序来部署实例或虚拟机(VM)。为简单起见,此配置在支持虚拟机硬件加速的计算节点上使用快速EMUlator(QEMU)管理程序和基于内核的VM(KVM)扩展。在旧硬件上,此配置使用通用QEMU管理程序。

    nova-compute调用libvirtd来创建虚拟机:

    1:安装软件包:

    [root@compute01 ~]# yum install openstack-nova-compute -y

    2:编辑/etc/nova/nova.conf文件并完成以下操作:

    在此[DEFAULT]部分中,仅启用计算和元数据API:

    [DEFAULT]
    enabled_apis = osapi_compute,metadata

    在该[DEFAULT]部分中,配置RabbitMQ消息队列访问:

    [DEFAULT]
    enabled_apis = osapi_compute,metadata
    transport_url = rabbit://openstack:huayun@controller01

    [api][keystone_authtoken]部分中,配置身份服务访问:

    [api]
    auth_strategy = keystone

    [keystone_authtoken]
    auth_url = http://controller01:5000/v3
    memcached_servers = controller01:11211
    auth_type = password
    project_domain_name = default
    user_domain_name = default
    project_name = service
    username = nova
    password = huayun

     在该[DEFAULT]部分中,配置my_ip选项:

    [DEFAULT]
    enabled_apis = osapi_compute,metadata
    transport_url = rabbit://openstack:huayun@controller01
    my_ip = 10.100.214.202

    在本[DEFAULT]节中,启用对网络服务的支持:

    [DEFAULT]
    .......

    use_neutron = True
    firewall_driver = nova.virt.firewall.NoopFirewallDriver

    在该[vnc]部分中,启用和配置远程控制台访问:

    [vnc]
    enabled = True
    server_listen = 0.0.0.0
    server_proxyclient_address = $my_ip
    novncproxy_base_url = http://controller01:6080/vnc_auto.html

    在该[glance]部分中,配置图像服务API的位置:

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

    在该[oslo_concurrency]部分中,配置锁定路径:

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

    在该[placement]部分中,配置Placement API:

    [placement]
    os_region_name = RegionOne
    project_domain_name = Default
    project_name = service
    auth_type = password
    user_domain_name = Default
    auth_url = http://controller01:5000/v3
    username = placement
    password = huayun

    最终却确定安装:

    1. 确定您的计算节点是否支持虚拟机的硬件加速:

    [root@compute01 ~]# egrep -c '(vmx|svm)' /proc/cpuinfo
    2

    编辑文件中[libvirt]部分,/etc/nova/nova.conf如下所示:

    [libvirt]
    virt_type = qemu

    启动Compute服务及其相关性,并将其配置为在系统启动时自动启动:

    [root@compute01 ~]# systemctl enable libvirtd.service openstack-nova-compute.service
    Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service to /usr/lib/systemd/system/openstack-nova-compute.service.
    [root@compute01 ~]# systemctl start libvirtd.service openstack-nova-compute.service
    [root@compute01 ~]#

    验证:

    在控制节点上进行验证:

    [root@controller01 ~]# source admin-openrc
    [root@controller01 ~]#
    [root@controller01 ~]#
    [root@controller01 ~]# openstack compute service list
    +----+------------------+--------------+----------+---------+-------+----------------------------+
    | ID | Binary | Host | Zone | Status | State | Updated At |
    +----+------------------+--------------+----------+---------+-------+----------------------------+
    | 1 | nova-consoleauth | controller01 | internal | enabled | up | 2020-05-24T10:18:56.000000 |
    | 2 | nova-conductor | controller01 | internal | enabled | up | 2020-05-24T10:18:57.000000 |
    | 3 | nova-scheduler | controller01 | internal | enabled | up | 2020-05-24T10:18:57.000000 |
    | 6 | nova-compute | compute01 | nova | enabled | up | 2020-05-24T10:18:57.000000 |
    +----+------------------+--------------+----------+---------+-------+----------------------------+

    发现计算节点主机:

    [root@controller01 ~]# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
    Found 2 cell mappings.
    Skipping cell0 since it does not contain hosts.
    Getting computes from cell 'cell1': f6a79410-c689-466c-ad20-705a87170ea9
    Checking host mapping for compute host 'compute01': 6bdf239a-4667-49d7-892f-4379c3c40fe6
    Creating host mapping for compute host 'compute01': 6bdf239a-4667-49d7-892f-4379c3c40fe6
    Found 1 unmapped computes in cell: f6a79410-c689-466c-ad20-705a87170ea9

    注意:When you add new compute nodes, you must run nova-manage cell_v2 discover_hosts on the controller node to register those new compute nodes. Alternatively, you can set an appropriate interval in /etc/nova/nova.conf:

    [scheduler]
    discover_hosts_in_cells_interval = 300
