如何批量检查表并进行repair,optimize

#!/bin/bash

host_name=192.168.0.123

user_name=xiaomo

user_pwd=my_pwd

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
