OpenStack排错常用步骤和命令

1.查看日志

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。日志路径在/var/log/下。

哪里有问题就去哪里找：去相应的日志文件夹查看日志。

比如上传镜像报错，就去/var/log/glance/

如果实例启动失败，就去/var/log/nova下查看。注意nova的日志分布于controller节点和compute节点

2.端口被占用

比如keystone集成到  里了，使用80端口。如果80端口被其他服务占用，那就完蛋了。

正常情况是：

[root@linuxidc ~]# lsof -i:80

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

httpd 11267 root 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 108466 apache 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 108467 apache 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 108468 apache 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 108469 apache 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 108470 apache 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 108597 apache 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 108598 apache 8u IPv6 41441 0t0 TCP *:http (LISTEN)

httpd 109362 apache 8u IPv6 41441 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

openstack project list

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

nova-manage --version

14.0.2

对应着N版本

6.在Mikata中：

查看所有的组件状态：openstack-status
