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

systemctl start mariadb.service

tail /var/log/keystone/keystone.log
vim /var/log/mariadb/mariadb.log
