1、 ERROR:1045 SOLUTION:

(1).关闭mysql # service mariadb stop(systemctl stop mariadb.service) (2).屏蔽权限 # mysqld_safe –skip-grant-table 屏幕出现: Starting demo from ….. (3)新开起一个终端输入 # mysql -u root mysql mysql> delete from user where USER=”; mysql> FLUSH PRIVILEGES;//记得要这句话,否则如果关闭先前的终端,又会出现原来的错误 mysql> \q (4)、systemctl start mariadb.service

2、 ERROR:1290 SOLUTION: mysql>flush privileges;

3、 配置nova.conf时在[libvirt]下加virt_type=qemu cpu_mode=host-model

4、 问题:网页登录dashboard出现500 Internal Server Error错误

查看/var/log/httpd/error_log日志: [core:error] [pid 5643] [client 192.168.47.200:29381] End of script output before headers: django.wsgi 解决方法:在/etc/httpd/conf.d/openstack-dashboard.conf文件中,添加 WSGIApplicationGroup %{GLOBAL}

5、 问题:dashboard登录异常 /var/log/httpd/error_log :”Unable to create a new session key. “缓存有问题

解决办法:将 /etc/openstack-dashboard/local_settings 里的 SESSION_ENGINE = 'django.contrib.sessions.backends.cache' SESSION_ENGINE = 'django.contrib.sessions.backends.file'
