MySql tables Corruption Checking

[2 Grey Star Level]

Hi Gurus,

I want to create a script to check the status of the mysql db tables, have already done it, my script is creating a simple file with all the status info, and sending me an email too.

But what I’m looking for;
I just want to get an email, when the status is not equal to OK … that’s it.

Can any one help, thanks, best regards.
EL

script:
=======
#!/bin/bash

#Set Credentials
export HOST=`hostname`
export USER=abcd
export PASSWORD=abcd
export DATABASE=abcd
export FILE=/home/mysql/$DATABASE_check.txt
## checking process
echo checking process of $DATABASE@$HOST
echo
echo START_TIME “>>>>>> `date +%m_%d_%Y:%H:%M:%S`”
mysqlcheck –user=$USER –password=$PASSWORD $DATABASE
echo END_TIME “>>>>>> `date +%m_%d_%Y:%H:%M:%S`”
mail -s “MySql Tables check – abcd@abcd ” el123@yahoo.com check.log &

Answer #1

Hello,

A simple way to do this would be to set a second script to run on a cron, that greps /home/mysql/$DATABASE_check.txt and emails you if certain keywords are found.

I would recommend you methods below to get back mysql data, but in case they won’t be effective, you may apply https://www.repairtoolbox.com/mysqlrepair.html Repair Toolbox for MySQL

Method 1.
Step 1. Log into mysql as administrator
mysql -uroot -p
Step 2. Select the database containing the corrupted table, i.e., ‘use {database name};’
mysql> use {database name};
Step 3. Show tables your corrupted table should be listed
mysql> show tables;
Step 4. Repair table
mysql> repair table {bad_table_name};

Method 2.
Step 1. Login to your MySQL server using Secure Shell (SSH).
Step 2. Repairing MyISAM mySQL Tables/Databases.
cd /var/lib/mysql/DBNAME
myisamchk -r -f tables.MYI
Please note that MyISAM is a default storage engine of MySQL, unless you change it. Mostly MyISAM is set as default engine to check and repair all the tables in the mysql database.
