本文介绍mysql定时批量检查表repair和优化表optimize table的shell脚本，对于MySQL数据库的定期维护相当有用！如下所示：

#!/bin/bash host_name=192.168.0.123 user_name=jincon.com user_pwd=jincon.com database=my_db_name need_optmize_table=true tables=$(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "show tables") for table_name in $tables do check_result=$(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 # 优化表,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") fi done
