===== 出現的警告與異常訊息解法 =====
==== 1. WARNING: Turning off multicore support, since pigz isn't there. ====
  * 安裝 pigz 來解決 <code sh>
yum install pigz
</code>

==== 2.mysqldump: Got error: 1142: SELECT,LOCK TABL command denied to user 'root'@'localhost' for table 'cond_instances' when using LOCK TABLES ====
  * 參數檔內的 CONFIG_mysql_dump_single_transaction 設為'yes' 來解決 <file>
:
# While a --single-transaction dump is in process, to ensure a valid dump file (correct table contents and
# binary log coordinates), no other connection should use the following statements: ALTER TABLE, CREATE TABLE,
# DROP TABLE, RENAME TABLE, TRUNCATE TABLE. A consistent read is not isolated from those statements, so use of
# them on a table to be dumped can cause the SELECT that is performed by mysqldump to retrieve the table
# contents to obtain incorrect contents or fail.
CONFIG_mysql_dump_single_transaction='yes'
