openstack私有云搭建（2023年私有云）
一、修改主机名（所有节点）
[root@controller ~]# hostnamectl set-hostname controller [root@controller ~]# hostname controller [root@compute ~]# hostnamectl set-hostname compute [root@compute ~]# hostname compute [root@compute ~]#
二、配置主机名映射（所有节点）
[root@controller ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.200.4 controller 192.168.200.89 compute [root@compute ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.200.4 controller 192.168.200.89 compute
三、配置YUM源（所有节点）
[root@controller ~]# rm -rf /etc/yum.repos.d/* [root@controller ~]# cat /etc/yum.repos.d/local.repo [centos] name=centos baseurl=http://192.168.200.159/centos/ gpgcheck=0 enabled=1 [iaas] name=iaas baseurl=http://192.168.200.159/iaas/iaas-repo gpgcheck=0 enabled=1 [root@compute ~]# rm -rf /etc/yum.repos.d/* [root@compute ~]# cat /etc/yum.repos.d/local.repo [centos] name=centos baseurl=http://192.168.200.159/centos/ gpgcheck=0 enabled=1 [iaas] name=iaas baseurl=http://192.168.200.159/iaas/iaas-repo gpgcheck=0 enabled=1
四、配置免密登录（controller节点）
[root@controller ~]# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: SHA256:K36rKn8ounJCrhgnbilv2bJuC0H7iMznOGYMCgbM79M root@controller The key's randomart image is: +---[RSA 2048]----+ | | | | |o. | |oo. | |o.. S | |*+o. . | |&++=... . | |B&%ooE... | |%%*O+ooo.. | +----[SHA256]-----+ [root@controller ~]# [root@controller ~]# ssh-copy-id controller /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" The authenticity of host 'controller (192.168.200.4)' can't be established. ECDSA key fingerprint is SHA256:molES9e8Fjgg1JSWMT5bRTg2l5A56dR4ReinDM2o4Ls. ECDSA key fingerprint is MD5:56:ce:b3:a6:84:b0:d1:d0:b9:01:20:b3:4d:5e:e5:13. Are you sure you want to continue connecting (yes/no)? yes /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys root@controller's password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'controller'" and check to make sure that only the key(s) you wanted were added. [root@controller ~]# [root@controller ~]# ssh-copy-id compute /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys root@compute's password: Number of key(s) added: 1 Now try logging into the machine, with: "ssh 'compute'" and check to make sure that only the key(s) you wanted were added. [root@controller ~]#

[root@controller openstack]# scp openrc.sh root@compute:/etc/openstack/
openrc.sh 100% 4962 2.5MB/s 00:00
八、执行脚本（所有节点）
#执行完这两个脚本重启一下这两台机子 [root@controller openstack]# iaas-pre-host.sh [root@compute ~]# iaas-pre-host.sh
重启完之后，继续执行脚本（controller节点）
#等controller节点的这些脚本成功执行完了之后，在执行compute节点的脚本 iaas-install-mysql.sh && iaas-install-keystone.sh && iaas-install-glance.sh \ && iaas-install-placement.sh && iaas-install-nova-controller.sh \ && iaas-install-neutron-controller.sh && iaas-install-dashboard.sh \ && iaas-install-cinder-controller.sh && iaas-install-swift-controller.sh \ && iaas-install-heat.sh && iaas-install-manila-controller.sh \ && iaas-install-cloudkitty.sh && iaas-install-barbican.sh
（上面这些脚本执行完，compute节点执行脚本）
iaas-install-nova-compute.sh && iaas-install-neutron-compute.sh \ && iaas-install-cinder-compute.sh && iaas-install-swift-compute.sh \ && iaas-install-manila-compute.sh
（openstack搭建完成！）
