Troubleshoot for Root Access Denied on MySqlDump

Background

We received an automatic email saying the mysqldump: Got error: 1045: “Access denied for user ‘root’@’localhost’ (using password: YES)” when trying to connect and this is related to automysqlbackup.

When we test this by running:

automysqlbackup

the error will show up and the backup file on /var/lib/automysql/daily are very small and when unzipped it’s no content at all.

We are not sure what caused this to stop working as the other virtual server are working ok for automysqlbackup.

Temporary Solution

The automysqlbackup has a config file: /etc/default/automysqlbackup and by default the password is getting from /etc/mysql/debian.cnf which confirmed is correct one

PASSWORD=`grep password /etc/mysql/debian.cnf | tail -n 1 | cut -d"=" -f2 | awk '{print $1}' `

So we decided to uncomment this line to hardcoded into:

PASSWORD=”the-root-password”

Tested and the SQL backup worked OK.

At this stage, this is a temporary solution and we are still digging into it.
