Are you getting this error on your WordPress website?

“error establishing database connection”

Create a file mysql.sh with this code :

#!/bin/bash
UP=$(/etc/init.d/mysql status | grep running | grep -v not | wc -l);
if [ "$UP" -ne 1 ];
then
echo "MySQL is down.";
service mysql start

else
echo "All is well.";
fi

$ chmod +x mysql.sh
$ crontab -e

One file will open after running the above command. Now, you just add the below line at the end of the file and after that save it.

*/5 * * * * /<path>/mysql.sh

If you are getting this error :

“fi” unexpected (expecting “then”) in shell scripts

then you have to convert the file with dos to unix converter. I have used one online: http://newline.nadav.org/
