1.问题描述

安装keystone在创建用户时报错：

The request you have made requires authentication. (HTTP 401) (Request-ID: req-03560e9f-bacc-4b0f-ac00-6ee4030cab8a)

2.检查过程

1.登陆mysql，查看keystone数据库下有没有生成新表

# mysql

use keystone;

show tables;

发现keyston数据库下没有表生成，理论上运行如下语句后会生成表：

# su -s /bin/sh -c "keystone-manage db_sync" keystone

2.使用授权帐号和密码尝试登陆mysql

mysql -h localhost -u keystone -pKEYSTONE_DBPASS    --登陆成功

mysql -h controller -u keystone -pKEYSTONE_DBPASS   --登陆失败

理论上使用controller主机名能登陆，因为授权对象包括%和localhost

3.查看keystone日志

# vim /var/log/keystone/keystone.log

2018-07-20 13:59:29.019 2958 CRITICAL keystone [-] OperationalError: (pymysql.err.OperationalError) (1045, u"Access denied for user 'keystone'@'controller' (using password: YES)")

发现keystone登陆失败信息

3.解决方法

经过多次测试，如果在mysql安全初始化时，不移除匿名用户、删除test数据库，就会出现以上授权问题，导致无法写入表

# mysql_secure_installation

Remove anonymous users? [Y/n] Y

 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This

ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n

 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can

access.  This is also intended only for testing, and should be removed

before moving into a production environment.

Remove test database and access to it? [Y/n] Y

 - Dropping test database...

 ... Success!

 - Removing privileges on test database...

自动脚本：

# mysql_secure_installation<<EOF

n

Y

Y

Y

Y

EOF
