实现MySQL定时批量检查表repair和优化表optimize table的shell脚本
本文介绍mysql定时批量检查表repair和优化表optimizetable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$database-A-Bse"showtables")
fortable_namein$tables
do
check_result=$(mysql-h$host_name-u$user_name-p$user_pwd$database-A-Bse
"checktable$table_name"|awk'{print$4}')
if["$check_result"="OK"]
then
echo"It'snoneedtorepairtable$table_name"
else
echo$(mysql-h$host_name-u$user_name-p$user_pwd$database-A-Bse
"repairtable$table_name")
fi
#优化表,可提高性能
if[$need_optmize_table=true]
then
echo$(mysql-h$host_name-u$user_name-p$user_pwd$database-A-Bse
"optimizetable$table_name")
fi
done
