投稿:shichen2014

这篇文章主要介绍了实现MySQL定时批量检查表repair和优化表optimize table的shell脚本,非常实用,需要的朋友可以参考下

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
