mysql:ERROR 3678 (HY000) at line 1: Schema directory './zabbix' already exists.

1,故障现象：

mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 3678 (HY000) at line 1: Schema directory './zabbix' already exists. This must be resolved manually 
(e.g. by moving the schema directory to another location).

2，解决办法：

建库时报已经存在该数据库文件夹了。但通过 mysql-client连接发现不存在。

[root@localhost mysql]# rm -rf zabbix/

 再次建库，就可以成功完成
