#                                    计算节点 nova组件部署安装                                                #
#############################################################################################################1、主机名修改 host文件解析[root@localhost ~] hostnamectl set-hostname computer001
[root@localhost ~] vim /etc/hosts
192.168.40.151 controller
192.168.40.151 computer001
2、yum源配置
3、时间服务安装
4、永久关闭防火墙（firewalld和selinux）
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld          #永久性关闭防火墙
[root@localhost ~]# setenforce 0                          #临时关闭selinux
[root@localhost ~]# vim /etc/selinux/config              #永久性关闭selinux
SELINUX=disabled
5、重启
[root@localhost ~]# reboot
6、nova组件安装
[root@computer001 ~]# yum install openstack-nova-compute
