### 命令行参数配置DSN
SOAR 最新版本已经使用`go-sql-driver`替代了`mymysql`，DSN将使用`go-sql-driver`格式并且保持向前兼容，请参考[go-sql-driver](https://github.com/go-sql-driver/mysql#dsn-data-source-name)文档。
**以下DSN格式不再推荐使用**
> 账号密码中如包含特殊符号(如：'@',':','/'等)可在配置文件中设置，存在特殊字符的情况不适合在命令行中使用。目前`soar`只支持 tcp 协议的 MySQL 数据库连接方式，如需要配置本机MySQL环境建议将`localhost`修改为'127.0.0.1'，并检查对应的 'user'@'127.0.0.1' 账号是否存在。
