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/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" ] thenecho "It"s no need to repair table $table_name" elseecho $（mysql -h$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 ] thenecho $（mysql -h$host_name -u$user_name -p$user_pwd $database -A -Bse "optimize table $table_name"） fidone
