1.查看日志

OpenStack的日志系统设计的非常棒 大多数的问题都能从日志中找到原因
日志路径通常在/var/log/下
在这里插入图片描述

2.端口被占用

比如keystone集成到apache里了,使用80端口。如果80端口被其他服务占用,那就完了
正常情况:

[root@controller ~]# lsof -i:80
COMMAND   PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
httpd    9393   root    4u  IPv6 321882      0t0  TCP *:http (LISTEN)
httpd   11890 apache    4u  IPv6 321882      0t0  TCP *:http (LISTEN)
httpd   11891 apache    4u  IPv6 321882      0t0  TCP *:http (LISTEN)
httpd   11892 apache    4u  IPv6 321882      0t0  TCP *:http (LISTEN)
httpd   11893 apache    4u  IPv6 321882      0t0  TCP *:http (LISTEN)
httpd   11894 apache    4u  IPv6 321882      0t0  TCP *:http (LISTEN)
httpd   20185 apache    4u  IPv6 321882      0t0  TCP *:http (LISTEN)
httpd   20211 apache    4u  IPv6 321882      0t0  TCP *:http (LISTEN)

3.查看租户/工程

租户tenant和工程project在Openstack中本质是一样的。新版本已经不再区分这2个概念

4.检查服务状态

ps -aux | grep keystone 或者ps -ef | grep keystone

5.查看openstack发行版本

nova是从openstack第一版就出现的"祖师爷"组件,借他的版本号可以知晓openstack的版本
