三台节点

#controller节点
nat:192.168.0.110       仅主机:10.0.1.110
#ccomputel01节点
nat:192.168.0.120       仅主机:10.0.1.120
#ccomputel02节点
nat:192.168.0.130       仅主机:10.0.1.130

网卡配置

其他节点配置相同,只有IP不同
#nat
[root@controller ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
TYPE=Ethernet
BROWSER_ONLY=no
BOOTPROTO=none
DEFROUTE=yes
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=192.168.0.110
PREFIX=24
GATEWAY=192.168.0.254
DNS1=223.5.5.5

#仅主机
[root@controller ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1
BOOTPROTO=static
DEVICE=eth1
ONBOOT=yes
IPADDR=10.0.1.110
PREFIX=24
GATEWAY=10.0.1.1
DNS=223.5.5.5

控制节点

ssh分发秘钥

[root@controller ~]# yum install -y bind-utils sshpass
[root@controller ~]# mkdir -p /server/scripts
[root@controller ~]# cat >/server/scripts/fenfa_pub.sh<< EOF
#!/bin/bash
ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ''
for ip in 110 120 130
do
sshpass -p123456 ssh-copy-id -o StrictHostKeyChecking=no 10.0.1.\$ip
done
EOF

sh /server/scripts/fenfa_pub.sh 

hosts解析

[root@controller ~]# cat >>/etc/hosts <<EOF
192.168.0.110 controller 
192.168.0.120 computel01
192.168.0.130 computel02
EOF

for ip in 120 130 ;do scp -rp /etc/hosts root@192.168.0.$ip:/etc/hosts ;done

[root@controller ~]# ping computel01
PING computel01 (10.0.1.120) 56(84) bytes of data.
64 bytes from computel01 (192.168.0.120): icmp_seq=1 ttl=64 time=0.432 ms

[root@controller ~]# ping computel02
PING computel02 (10.0.1.130) 56(84) bytes of data.
64 bytes from computel02 (10.0.1.130): icmp_seq=1 ttl=64 time=0.389 ms

全部节点的基础优化

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config
systemctl stop NetworkManager
systemctl disable NetworkManager

上传软件包——openstack-rocky压缩包
链接: https://pan.baidu.com/s/1raa5Wj8LEDQ0DwSe7vDPeQ 提取码: e4pd
全部节点,解压到/opt目录下

如下所示:
[root@controller ~]# ls
openstack_rocky.tar.gz
[root@controller ~]# tar -zxf openstack_rocky.tar.gz -C /opt/
[root@controller ~]# cd /opt/
[root@controller opt]# du -h
2.4M    ./openstack_rocky/repodata
306M    ./openstack_rocky
306M    .

将光盘镜像挂载

[root@controller opt]# echo  '/dev/sr0    /mnt    iso9660 defaults    0 0' >>/etc/fstab
[root@controller opt]# mount /dev/sr0 /mnt/
mount: /dev/sr0 is write-protected, mounting read-only
[root@controller opt]# df -h

yum源

[root@controller opt]# cd /etc/yum.repos.d/
[root@controller yum.repos.d]# 
[root@controller yum.repos.d]# mkdir backup #创建备份目录
[root@controller yum.repos.d]# mv ./C* ./epel.repo backup/  #将当前目录下,所有内容转移到./backup
[root@controller yum.repos.d]# cp backup/CentOS-Base.repo local.repo
[root@controller yum.repos.d]# vim local.repo

#开启缓存
[root@controller yum.repos.d]# sed -i 's#keepcache=0#keepcache=1#g' /etc/yum.conf
[root@controller yum.repos.d]# yum clean all                ##检验本地源是否正常

时间同步

#controller节点
yum install chrony -y
vim /etc/chrony.conf 
  server ntp1.aliyun.com iburst
  allow 192.168.0.10/24

systemctl restart chronyd.service 
systemctl enable chronyd.service 
chronyc sources

#其他节点上配置
yum install chrony -y
vim /etc/chrony.conf 
  server controller iburst

systemctl restart chronyd.service 
systemctl enable chronyd.service 
chronyc sources

一键部署OpenStack

控制节点安装openstack-packstack工具

#安装openstack-packstack工具用于生成openstack应答文件(txt文本格式)

[root@controller ~]# yum install -y openstack-packstack
[root@controller ~]# packstack --gen-answer-file=openstack.txt
[root@controller ~]# ls
openstack_rocky.tar.gz  openstack.txt

修改一键部署配置文件的内容
具体内容建议查询了解其他的配置含义和作用

[root@controller ~]# vim openstack.txt
41行:y-n #SWIFT是OpenStack的对象存储组件,默认是Y,在生产环境中一般是不装,所以改n
50行:y-n #不安装该服务
97行:10.0.1.120,10.0.1.130 #计算节点ip地址
817 :physnet1           #flat网络这边要设置物理网卡名字
862 :physnet1:br-ex    #这边要设置物理网卡的名字
873:br-ex:eth0          #这边br-ex:eth0是网络节点的nat网卡,到时候安装完毕之后IP地址会漂到这个上
1185:y-n #DEMO是OpenStack联网下载一个测试镜像,这边没联网。说以改成n

还有一些网段需要修改以及密码这里使用sed正则表达式来全局修改

##更改密码(123456)
[root@controller ~]# sed -i -r 's/(.+_PW)=.+/\1=123456/' openstack.txt

##将主机ip修改为仅主机网络
sed -i -r 's/192.168.0.110/10.0.1.110/g' openstack.txt

#进行备份
egrep -v "^#|^$" openstack.txt >openstack.txt.bak1

[root@controller ~]# grep 'HOST=' openstack.txt
CONFIG_CONTROLLER_HOST=10.0.1.110
CONFIG_VCENTER_HOST=
CONFIG_STORAGE_HOST=10.0.1.110
CONFIG_SAHARA_HOST=10.0.1.110
CONFIG_AMQP_HOST=10.0.1.110
CONFIG_MARIADB_HOST=10.0.1.110
CONFIG_TEMPEST_HOST=
CONFIG_REDIS_HOST=10.0.1.110

使用下面的命令进行一键部署安装

#保证控制节点的仅主机网络网关打开
#在各个节点终端(可以多开几个窗口终端使用下面的命令查看日志信息)
[root@controller ~]# tail -f /var/log/messages
[root@computel01 ~]# tail -f /var/log/messages
[root@computel02 ~]# tail -f /var/log/messages

接下来就是耐心等待

[root@controller ~]# packstack --answer-file=openstack.txt
