nova-compute服务无法启动，根据日志，貌似是说computer1这台服务器无法找到，但是我把nova-compute服务就是安装在了computer1这台服务器上了，而且ping computer1 也是可以ping通的。nova-computer配置信息如下：

求大神帮忙看下。。。我觉得应该是个很简单的错误，就是自己看不出来。。。

centos还是ubuntu,

ubuntu参考这个：

如何对比的话，需要首先确定是哪个配置文件，否则无法对比。感觉你的配置里面多了一些内容。

是ubuntu的，我配置里多了一些neutron的内容，跟这个应该没关系吧？

贴的是哪个配置文件的，neutron后面有配置，可能这个不是多出的内容

计算节点上的my_ip 应该为计算节点的ip地址，不应该是控制节点的ip地址。

这个已修改，但是还是起不来服务，我觉得是neutron有问题影响了nova

再对照一下你controller节点的nova配置文件，在你配neutron之前，你的nova-compute服务可以起来吗

neterghost 发表于 2015-9-15 15:18
这次我是全都配置好后做的测试，故不知。。所以只能一点一点回滚测试了。。
感觉openstack ...

最好一点一点的配置，每个组件做完验证再做下一步，neutron比较复杂，毕竟是网路功能，配置的时候要小心，一个字母，空格的错误都会对下面造成错误。不过你这个问题应该还在nova的配置上了。

嗯，大不了从头来。。
不过我还是想找到原因，回头在遇到就不怕了，呵呵
谢谢你的帮助~
