工具名稱：mysqlha_skiperror.sh
工具用途：用於MySQL跳過主從錯誤
工具參數：options:
-P port 指定端口
-N number 指定跳過錯誤次數 不指定默認爲10次（如果不知道可以設置大一些，會記錄log）
-C error code Take , as the separator 指定跳過錯誤的狀態碼 可以跳過多個以，分隔
工具示例： mysqlha_skiperror.sh -P 4444 -C 1032
工具執行結果：
Could not execute Write_rows event on table test.t; Duplicate entry '23' for key 'PRIMARY', Error_code: 1062; handler error HA_ERR_FOUND_DUPP_KEY; the event's master log mysql-bin.000011, end_log_pos 6621
Could not execute Write_rows event on table test.t; Duplicate entry '24' for key 'PRIMARY', Error_code: 1062; handler error HA_ERR_FOUND_DUPP_KEY; the event's master log mysql-bin.000011, end_log_pos 6800
Could not execute Delete_rows event on table testone.t1; Can't find record in 't1', Error_code: 1032; handler error HA_ERR_KEY_NOT_FOUND; the event's master log mysql-bin.000011, end_log_pos 6983

count_total=3
工具log：會在當前dir下生成skiperror.txt 裏面存的是詳細的報錯內容，看完可以刪除。
