gnocchi的端口是8041，aodh是8042，我安装好，照着官网配置的，都正常。我的尝试：
 

1、将8042、8041端口用http服务监听，修改vim /etc/httpd/conf.d/wsgi-keystone.conf，但是端口是打开了，但是又报更离谱的错误

2、使用防火墙iptables 或者firewalld服务，来开启端口，reload后查询端口输出yes，但是用ss -ltpn |grep 8041 没有结果，运行gnnocchi和aodh服务还是报同样的错误

错误如下：

 [root@controller aodh]#  gnocchi resource list

[root@controller aodh]# aodh alarm create --name cpu_hi --type gnocchi_resources_threshold --metric cpu_util --threshold 70.0  --comparison-operator gt   --aggregation-method mean   --granularity 600   --evaluation-periods 3   --alarm-action 'log://'  --resource-id d6cdcd9c-be3d-4e21-8c34-08aba348963a --resource-type instance

 有点不知所措了，我觉得就是端口的问题，但是不知道怎么配置，怎么监听，请问各位大佬？
