7、配置域名解析


【controller】


[root@controller ~]# vi /etc/hosts
[root@controller ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.10  controller
192.168.1.20  compute
[root@controller ~]# 


【compute】


[root@compute ~]# vi /etc/hosts
[root@compute ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.10  controller
192.168.1.20  compute
[root@compute ~]# 


8、关闭防火墙和修改SELINUX安全模式


【controller、compute】


以compute节点为例,compute节点进行相同操作即可


关闭防火墙并设置防火墙开机不自启


[root@controller ~]# systemctl stop firewalld;systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@controller ~]# 


修改SELINUX安全模式(临时修改、永久修改)


(准确的来说,permissive是允许放行通过,即发出警告⚠但不阻止🚫;disabled是关闭SELINUX安全模式,既不发出安全警告,也不阻止。)


[root@controller ~]# setenforce 0 #临时关闭SELINUX
[root@controller ~]# getenforce # 查询SELINUX模式
Permissive
[root@controller ~]# sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config 
[root@controller ~]# cat /etc/selinux/config 
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=permissive
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted 
[root@controller ~]# 


同理,compute节点进行以上相同操作即可。


9、在【compute】节点上进行空白分区的划分,cinder存储和swift存储。


首先划出一整块磁盘空间,再进行分区。


[root@compute ~]# lsblk 
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0  1.7T  0 disk 
├─sda1   8:1    0  500M  0 part /boot

└─sda3   8:3    0    1T  0 part /
[root@compute ~]# fdisk /dev/sda
The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

[root@compute ~]# partprobe /dev/sda
[root@compute ~]# lsblk

再进入到sda4磁盘,进行分区。cinder存储和swift存储。


[root@compute ~]# fdisk /dev/sda4

11、执行相关脚本安装各个组件服务


(1)通过脚本安装服务


【controller】


[root@controller ~]# iaas-pre-host.sh 
[root@controller ~]# reboot


【compute】


[root@compute ~]# iaas-pre-host.sh 
[root@compute ~]# reboot


(2)通过脚本安装数据库服务


【controller】


[root@controller ~]# iaas-install-mysql.sh


【compute】


[root@compute ~]# yum -y install  MySQL-python


(3)通过脚本安装keystone服务


【controller】


[root@controller ~]# iaas-install-keystone.sh


(4)通过脚本安装glance服务


【controller】


[root@controller ~]# iaas-install-glance.sh


上传镜像并使用命令查询是否上传成功

(5)通过脚本安装nova服务


【controller】


[root@controller ~]# iaas-install-nova-controller.sh



【compute】


[root@compute ~]# iaas-install-nova-compute.sh



(6)通过脚本安装neutron服务


【controller】


[root@controller ~]# iaas-install-neutron-controller.sh


【compute】


[root@compute ~]# iaas-install-neutron-compute.sh


注意:使用真实服务器搭建的话,网络模式选择vlan模式;使用虚拟机搭建的话,网络模式选择flat模式。


(7)通过脚本安装dashboard服务


【controller】


[root@controller ~]# iaas-install-dashboard.sh


(8)通过脚本安装Cinder服务


【controler】


[root@controller ~]# iaas-install-cinder-controller.sh


【compute】


[root@compute ~]# iaas-install-cinder-compute.sh


(9)通过脚本安装Swift服务


【controller】


[root@controller ~]# iaas-install-swift-controller.sh


【compute】


[root@compute ~]# iaas-install-swift-compute.sh


(10)通过脚本安装heat服务


【controller】


[root@controller ~]# iaas-install-heat.sh


(11)通过脚本安装Zun服务


【controller】


[root@controller ~]# iaas-install-zun-controller.sh


【compute】


[root@compute ~]# iaas-install-zun-compute.sh


(12)通过脚本安装Ceilometer服务


【controller】


[root@controller ~]# iaas-install-ceilometer-controller.sh


【compute】


[root@compute~]# iaas-install-ceilometer-compute.sh


(13)通过脚本安装Aodh服务


【controller】


[root@controller ~]# iaas-install-aodh.sh


12、添加控制节点资源到云平台


【controller】


修改openrc.sh


把compute节点的IP地址和主机名改为controller节点的IP和主机名


在控制节点运行iaas-install-nova-compute.sh


执行过程中需要确认登录controller节点和输入controller节点root用户密码。


修改openrc.sh配置文件


#Compute Node Manager IP. example:x.x.x.x
HOST_IP_NODE=192.168.1.10
#Compute Node hostname. example:compute
HOST_NAME_NODE=controller


[root@controller ~]# iaas-install-nova-compute.sh
