1,故障現象：
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，解決辦法：
建庫時報已經存在該數據庫文件夾了。但通過 mysql-client連接發現不存在。
[root@localhost mysql]# rm -rf zabbix/
再次建庫，就可以成功完成
