【mysql错误】SELECT command denied to user 'longfor_read'@'id地址' for table 'help_topic'

在线错误提示：

SELECT command denied to user 'longfor_read'@'id地址' for table 'help_topic'；

缘由：mysql用户没有执行查询help_topic表的权限，须要root用户受权。

解决方案：

# ./mysql -uroot -p

> source /path/to/phpmyadmin/examples/create_tables.sql;

> GRANT SELECT, INSERT, UPDATE, DELETE ON phpmyadmin.help_topic TO 'longfor_read'@'id地址' IDENTIFIED BY '';

> flush privileges;

> exit;
