命令启动后，没有真的启动，db_sync_short_video_oss_r2m0_d也没有打日志

可以看sync_d日志，当同步进程成功启动后，会变成db_sync_short_video_oss_r2m0_d目录，目前看日志有如下报错
May 17 15:42:17 warning sync_d[]: [tid:143826] [MetaData::loadGlobalInfo] myshard_user empty ‘SYNC‘ May 17 15:42:17 crit sync_d[]: [tid:143826] [MetaData::loadSyncInfo] Unknown column ‘area_no‘ in ‘field list‘ May 17 15:45:58 warning sync_d[]: [tid:143899] [MetaData::loadGlobalInfo] myshard_user empty ‘SYNC‘ May 17 15:45:58 crit sync_d[]: [tid:143899] [MetaData::loadSyncInfo] Unknown column ‘area_no‘ in ‘field list‘
说缺少了一个叫area_no的字段，这个需要在sync_server表多加入一个字段
alter table myshard_sync_server add area_no int(11) DEFAULT 1;
同时在myshard.xml上的area字段，也改为1，这个表示区域号，美洲区，欧洲区，亚洲区的编号

为了加载元数据，重启shard，shardadmin,sync,重启完以后，看一下重启的时间是不是刚刚，这样保证是已经成功重启的，另外所有节点都加入nc脚本，同时去看是否有人来拉取自己的数据
