本文介紹mysql定時批量檢查表repair和優化表optimize table的shell腳本，對于MySQL數據庫的定期維護相當有用！如下所示：

#!/bin/bashhost_name=192.168.0.123user_name=jincon.comuser_pwd=jincon.com database=my_db_nameneed_optmize_table=truetables=$(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "show tables")for table_name in $tablesdo check_result=$(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "check table $table_name" | awk '{ print $4 }') if [ "$check_result" = "OK" ] then  echo "It's no need to repair table $table_name" else  echo $(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "repair table $table_name") fi # 優化表,可提高性能 if [ $need_optmize_table = true ] then  echo $(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "optimize table $table_name") fidone
