CentOS 7部署OpenStack（5）—部署Nova计算节点

5534

安装基础环境

[iyunv@compute ~]# yum install -y http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

[iyunv@compute ~]# yum install -y centos-release-openstack-liberty

[iyunv@compute ~]# yum install -y python-openstackclient

安装nova-compute

[iyunv@compute ~]# yum install -y openstack-nova-compute sysfsutils

配置nova compute

控制节点和计算节点的配置几乎一模一样，只需修改一小部分，因此可以直接将控制节点的配置文件拷贝到计算节点即可。也可按照控制节点的步骤再来一次。

[iyunv@controller ~]# scp /etc/nova/nova.conf compute:/etc/nova/

[iyunv@compute ~]# vim /etc/nova/nova.conf

124 my_ip=192.168.1.12

1819 novncproxy_base_url=http://192.168.1.11:6080/vnc_auto.html

1827 vncserver_listen=0.0.0.0

1834 vnc_enabled=true

1837 vnc_keymap=en-us

2333 host=192.168.1.11

2726 virt_type=kvm    //要确定支持kvm，不支持可以改成qemu

启动服务

[iyunv@compute ~]# systemctl enable libvirtd openstack-nova-compute

[iyunv@compute ~]# systemctl start libvirtd openstack-nova-compute

查看验证

   在控制节点上进行查看

[iyunv@controller ~]# openstack host list

+------------+-------------+----------+

| Host Name  | Service     | Zone    |

+------------+-------------+----------+

| controller | consoleauth | internal |

| controller | scheduler   |internal |

| controller | cert        |internal |

| controller | conductor   |internal |

| compute    | compute     | nova    |

如果出现最后一行即表明安装成功
