记录一台单节点物理服务器使用PackStack部署OpenStack-Train版的操作
戴尔R720
系统:centos7.8.2003
cpu型号: E5-2670v2
2C8核32线程
内存 32G
网络环境:
eth0 192.168.100.106 物理外网
eth1 172.16.0.106 私有内网
服务器基础优化

安装train版yum源
yum install centos-release-openstack-train -y
安装openstack-packstack工具用于生成openstack应答文件
yum install openstack-packstack -y
packstack --gen-answer-file=openstack.txt
packstack --allinone #allinone模式
packstack --gen-answer-file=<file> #生成部署配置文件
packstack --answer-file=<file> #选择应答文件
packstack每个版本的配置文件均有小改动,不要修改错位置
可以详细学习一下配置文件的各个模块的配置参数,可根据自己实际需求更改
[19:57 root@localhost ~]# vim openstack.txt
41 CONFIG_SWIFT_INSTALL=n #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 CONFIG_AODH_INSTALL=n #y-n 不安装该服务
97 CONFIG_COMPUTE_HOSTS=192.168.100.106 #计算节点ip地址
795 CONFIG_NEUTRON_ML2_TYPE_DRIVERS=vxlan,flat
801 CONFIG_NEUTRON_ML2_TENANT_NETWORK_TYPES=vxlan
808 CONFIG_NEUTRON_ML2_MECHANISM_DRIVERS=openvswitch
813 CONFIG_NEUTRON_ML2_FLAT_NETWORKS=physnet1 #flat网络这边要设置物理网卡名字
840 CONFIG_NEUTRON_L2_AGENT=openvswitch #L2网络的代理模式,也可选择linuxbridge
858 CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-ex #这边要设置物理网卡的名字
869 CONFIG_NEUTRON_OVS_BRIDGE_IFACES=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
1181 CONFIG_PROVISION_DEMO=n #DEMO是OpenStack联网下载一个测试镜像,这边没联网。说以改成n
更改密码(123456)
sed -i -r 's/(.+_PW)=.+/\1=123456/' openstack.txt
备份配置文件
egrep -v "^#|^$" openstack.txt >openstack.txt.bak1
查看所有的主机ip地址是否都指定到eth0网卡
[20:01 root@localhost ~]# grep 'HOST=' openstack.txt
CONFIG_CONTROLLER_HOST=192.168.100.106
CONFIG_VCENTER_HOST=
CONFIG_STORAGE_HOST=192.168.100.106
CONFIG_SAHARA_HOST=192.168.100.106

回退leatherman版本
#不执行此步骤会故障报错
facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory
leatherman rpm包版本问题
[20:06 root@localhost ~/openstack]# yum list | grep leatherman
leatherman.x86_64 1.10.0-1.el7 @epel
leatherman-devel.x86_64 1.10.0-1.el7 epel
而facter需要1.3.0
[20:09 root@localhost ~/openstack]# facter -p
facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory
回退leatherman版本
yum downgrade leatherman -y
一键部署单节点
[20:15 root@localhost ~]# packstack --answer-file=openstack.txt

Additional information:
* Time synchronization installation was skipped. Please note that unsynchronized time on server instances might be problem for some OpenStack components.
* File /root/keystonerc_admin has been created on OpenStack client host 192.168.100.106. To use the command line tools you need to source the file.
* To access the OpenStack Dashboard browse to http://192.168.100.106/dashboard .
Please, find your login credentials stored in the keystonerc_admin in your home directory.
* The installation log file is available at: /var/tmp/packstack/20200614-205624-uEmdI2/openstack-setup.log
* The generated manifests are available at: /var/tmp/packstack/20200614-205624-uEmdI2/manifests
packstack部署禁止了openstack的dashbrard界面对域的支持,需要可打开
vim /etc/openstack-dashboard/local_settings
79 OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True
85 OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default'
461 TIME_ZONE = "Asia/Shanghai" #配置时区为亚洲上海
systemctl restart httpd.service memcached.service
因为packstack是通过封装puppet,httpd的配置端口文件中会生成监控端口的文件,会导致占用了nova-api的端口8774和8775,所以禁用掉即可
vim /etc/httpd/conf/ports.conf
#Listen 0.0.0.0:8774
#Listen 0.0.0.0:8775
Listen 0.0.0.0:8778
Listen 5000
Listen 80
Listen 8041
Listen 8777
systemctl restart httpd.service openstack-nova-api.service
#8774和8775端口是nova-api使用的端口
[21:17 root@localhost ~]# netstat -lntup|grep 877
