不挑用户，直接用root操作就行。

yum -y install openstack-packstack #基于Puppet工具 
#这一步会安装leatherman.x86_64 0:1.10.0-1.el7 但因版本不对导致下面报错，真是无语

packstack将使用下面的选项来安装
  --allinone            Shorthand for --install-hosts=<local ipaddr>
                        --novanetwork-pubif=<dev> --novacompute-privif=lo
                        --novanetwork-privif=lo --os-swift-install=y, this
                        option can be used to install an all in one OpenStack
                        on this host

packstack --allinone
马上就报错：

Pre installing Puppet and discovering hosts' details[ ERROR ]
facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory

[root@ecs-cos ~]#  find / -name leatherman_curl.so.1.3.0 #没找到，很快就返回，出乎意料

其实package是有的(Collection of C++ and CMake utility libraries: leatherman1.10.0)，但是版本不对，试着做个符号链接

ln -s /usr/lib64/leatherman_curl.so.1.10.0 /usr/lib64/leatherman_curl.so.1.3.0
又报错了
facter: error while loading shared libraries: leatherman_ruby.so.1.3.0: cannot open shared object file: No such file or directory

所以centos7.9是不是版本不合适？类似报错可能没完没了，停止，改用centos7.8，结果一模一样，无语
找到解决方法是yum downgrade leatherman（后面就不要做yum update否则又升级了），试了命令可以成功，还是切回centos7.9

上面一步很慢（有用yum安装一些包），而且报错了。切换为huawei yum源。再次执行。还是一样的报错。从Log文件看一下详情

Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install openstack-keystone' returned 1: Error: Package: python2-qpid-proton-0.26.0-2.el7.x86_64 (centos-openstack-train)

 You could try using --skip-broken to work around the problem

说到底，还是和上面的一样是包版本的问题。从下面的版本清单可以看出，我们应该用centos-openstack-train这个repo里的，而不用其他repo

[root@ecs-cos ~]# yum list leatherman --showduplicates

将/etc/yum.repos.d/下面的epel源配置文件里enable改为0，禁用掉这个repo。然后再次执行，结果非常好！完成了。

有一点不好的是，apache的配置文件里，未允许公网IP访问horizon，在/etc/httpd/conf.d/15-horizon_vhost.conf 添加ServerAlias 公网IP，然后systemctl reload httpd 即可

看一下版本，当然比devstack的要低（27.0）
[root@ecs-cos conf.d]# nova-manage --version
20.6.0

总之，感觉比devstack要顺利一些。
