MySQL实现批量检查表并进行repair与optimize的方法_MySQL

以下是shell的参考代码：

#!/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 &＃39;{ print $4 }&＃39;)
 if [ "$check_result" = "OK" ]
 then
  echo "It&＃39;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

也可以使用mysqlcheck命令，此方法可以在检查表并自动修复损坏的表，不过该过程比较耗时。
