#!/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
