部署簡介：openstack使用穩(wěn)定版的rocky版本devstack來部署。部署前準(zhǔn)備兩臺虛機(jī)，一臺作為compute，一臺controller。配置網(wǎng)絡(luò)使虛機(jī)可以連接到外網(wǎng)，停止防火墻，禁止防火墻開機(jī)自啟，關(guān)閉SELINUX。修改配置文件，設(shè)為disabled，配置/etc/hostname，/etc/hosts。配置stack用戶，新增運(yùn)行配置文件 local.conf后開啟部署。官網(wǎng)參考文檔https://docs.openstack.org/devstack/latest/guides/multinode-lab.html

部署詳情：
1.增加centos7的虛機(jī)，配置ip
2.打開 vi /etc/resolv.conf，增加 nameserver 8.8.8.8
重啟網(wǎng)絡(luò): service network restart
3.打開 vi /etc/sysconfig/network-scripts/ifcfg-ens160
增加
DNS1=8.8.8.8

重啟網(wǎng)絡(luò)

ifdown ens160 
ifup ens160

停止防火墻

systemctl stop firewalld.service

禁止firewall開機(jī)啟動

systemctl disable firewalld.service

關(guān)閉SELINUX。修改配置文件，設(shè)為disabled
vi /etc/selinux/config
SELINUX=disabled

vi /etc/hostname
comtroller 增加rocky-controller
compute增加rocky-compute

vi /etc/hosts
172.22.160.63 rocky-controller
172.22.160.61 rocky-compute

Centos默認(rèn)的更新源比較慢，換成國內(nèi)阿里云的源會快很多。
cd /etc/yum.repos.d/
mv CentOS-Base.repo CentOS-Base.repo.backup
wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
生成緩存
yum makecache

(3) pip下載超時(shí)
修改pip的源為國內(nèi)的源。
cd ~
mkdir .pip
cd .pip
vim pip.conf
配置內(nèi)容為
[global]
timeout = 6000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

/etc/hosts
下載devstack，安全openstack神器（dockey）

yum install git
 git clone -b stable/rocky https://git.openstack.org/openstack-dev/devstack

配置stack用戶

devstack/tools/create-stack-user.sh
mv devstack /opt/stack 
chown -R stack:stack /opt/stack/devstack
su - stack 
cd devstack

開啟部署

./stack.sh

問題1 安裝過程中報(bào)錯(cuò)Delta RPMs disabled because /usr/bin/applydeltarpm not installed.
yum provides '*/applydeltarpm'
yum install deltarpm
問題2 安裝過程中報(bào)錯(cuò) SyntaxError: '<' operator not allowed in environment markers
pip install --upgrade pip
pip install --upgrade setuptools
問題3 pip升級后執(zhí)行./stack.sh又被回退
原因安裝檢查版本不在范圍內(nèi)，后面又需要高版本。去掉cap-pip.txt 文件中,<10的部分。
Cannot uninstall 'pyOpenSSL'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
問題4 安裝過程中報(bào)錯(cuò)Cannot uninstall pyOpenSSL. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
pip show pyOpenSSL

虛機(jī)關(guān)機(jī)后自動重啟，但是https沒有安裝成功

安裝成功http://172.22.160.63/dashboard/用戶名密碼都是admin

關(guān)機(jī)后重啟
service httpd restart
iptables -F(虛機(jī)每次重啟都要執(zhí)行)
