使用RDO Packstack在CentOS 8上安装版本为Victoria的openstack
遇到的问题：
Failed to run remote script, stdout: skipping creation of hiera.yaml symlink
到 /etc/puppet/ 这个目录下创建 hiera.yaml文件，添加下面内容
---
:backends:
- yaml
:hierarchy:
- defaults
- "%{clientcert}"
- "%{environment}"
- global
:yaml:
# datadir is empty here, so hiera uses its defaults:
# - /var/lib/hiera on *nix
# - %CommonAppData%PuppetLabshieravar on Windows
# When specifying a datadir, make sure the directory exists.
:datadir: /var/tmp/packstack/68df299e9c644764b8bc20b786432ce1/hieradata
2.yum源问题，比如
Cannot prepare internal mirrorlist: No URLs in mirrorlist
3.按照安装步骤，不能在浏览器打开OpenStack
执行 systemctl restart httpd
4.openStack 打开非常慢的原因是因为 mysql LimitNOFILE 需要调增
进入到/etc/systemd/system/ 修改 mysqld.service
重启
systemctl daemon-reload
systemctl restart mysqld
5.创建实例失败
修改
/etc/nova/nova.conf
virt_type=qemu
