OpenStack启动镜像实例报错，无IP地址，linuxbridge-agent.log报错问题
作者：互联网
OpenStack版本Queens，完全按照官方文档安装，最后启动镜像实例时发现没有分配IP地址，使用openstack server list
[root@k8s-1 ~]# openstack server list +--------------------------------------+-------------------+--------+-------------------------+--------+---------+ | ID | Name | Status | Networks | Image | Flavor | +--------------------------------------+-------------------+--------+-------------------------+--------+---------+ | e8e5a9ce-2461-4e22-ab02-cf1400f590af | provider-instance | ACTIVE | provider=192.168.197.32 | cirros | m1.nano | +--------------------------------------+-------------------+--------+-------------------------+--------+---------+
查看/var/log/neutron/linuxbridge-agent.log时发现报错如下：

经过重启nova、neutron、keystone、glance以及httpd均无用，后来开始一点点检查配置文件，发现lock_path路径如下，检查文件权限时发现是root
[oslo_concurrency] # # From oslo.concurrency # # Enables or disables inter-process locks. (boolean value) #disable_process_locking = false # Directory to use for lock files. For security, the specified directory # should only be writable by the user running the processes that need locking. # Defaults to environment variable OSLO_LOCK_PATH. If external locks are used, # a lock path must be set. (string value) # lock_path = $state_path/lock lock_path = /var/lib/neutron/tmp [oslo_messaging_amqp] # # From oslo.messaging
修改权限
chown -R neutron:neutron /var/lib/neutron
再次重启systemctl restart neutron-linuxbridge-agent.service之后日志正常，重启镜像实例发现可以获取ip
总结：对于服务报错检查应该先从日志入手，再检查配置，分开每个服务逐一检查。对于本次OpenStack安装错误，也警醒自己，需要真正了解每个服务，端口和配置内容，服务原理。可能就因为文件权限这种小问题，就会导致服务异常，还是要细致认真，也希望能帮助到更多的人。
