本文介紹mysql定時批量檢查表repair和優(yōu)化表optimize table的shell腳本，對于MySQL數(shù)據(jù)庫的定期維護相當(dāng)有用！如下所示：
#!/bin/bashhost_name=192.168.0.123user_name=jincon.comuser_pwd=jincon.com database=my_db_nameneed_optmize_table=truetables=$(mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "show tables")for table_name in $tablesdo check_result=$(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 # 優(yōu)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") fidone新聞熱點
