openstack安装过程中报错及解决办法汇总

Openstack问题汇总

1．Yum install 不行

Could not resolve host: mirrorlist.centos.org？

vi /etc/resolv.conf

nameserver 8.8.8.8

nameserver 10.0.6.61

/etc/init.d/network restart

reboot

 

2．rabbitmq出错？

vi /etc/rabbitmq/rabbitmq-env.conf

在文件里面添加这一行：NODENAME=rabbit@localhost，保存

service rabbitmq-server start

 

3. 创建连接，开机启动

systemctl enable mariadb.service

systemctl start mariadb.service

 

4．重启rabbitmq，

systemctl start rabbitmq-server.service

 

5．查看日志

  tail /var/log/keystone/keystone.log

  vim /var/log/mariadb/mariadb.log

  cat /var/log/httpd/error_log

  vim /var/log/nova/nova-api.log

  

6．/usr/sbin/setenforce 0 立刻关闭 SELINUX

  1立即开启

 

7．Rabbitmq删除用户

  rabbitmqctl delete_user Username

 

8．查看端口8774：

  ss -ntl | grep 8774

 

9．重启nova-computer

  systemctl restart openstack-nova-compute.service
