Plesk 12.x / Linux :: MySQL DB Backup Script Not Working

May 31, 2015

This is on a CentOS 7.1, Plesk 12. New.

On Plesk 10.4 I had a script that backed up my MySQL databases separately. The script doesn't work now. I get an error:

ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES)‚Äč

Do I need to do something different with this new "MariaDB" thing?

Here's the script:

DB_BACKUP="/pat/to/databackup/`date +%Y-%m-%d`"
DB_USER="admin"
DB_PASSWD="-p`cat /etc/psa/.psa.shadow`"
HN=`hostname | awk -F. '{print $1}'`

Installed MySQL In /usr/local/mysql But Error In /var/lib/mysql

Jan 21, 2007

I installed the MySQL binary packages in /usr/local/mysql/ after removing the MySQL RPM package. MySQL is functioning when I executed /usr/local/mysql/bin/safe_mysqld. I reinstalled MySQL before I installed PHP. When I used a PHP script to access a MySQL database, it outputs an error:

Code:
Warning: mysqli::mysqli() [function.mysqli-mysqli]: (HY000/2002): can't connect to local mysql server through socket /var/lib/mysql/mysql.sock in index.php on line 2
However, I installed MySQL in /usr/local/mysql, not in /var/lib/mysql. How do I fix MySQL?

How To Restore Mysql Databases From /var/lib/mysql/user_database/ Files Only

Feb 11, 2008

I recently had a harddrive failure and luckliy I can still access certain directories on this failed drive. I can still access the /var/lib/mysql/ directory which holds all the users databases and have backed all these up separately using tar.

Now what I need to know is how do you restore these database files to another server? I tried simply untar'ing one of these to the new servers /var/lib/mysql/ direcotry and it stuffed Mysql up - it went offline. I had to get a cpanel tech to bring Mysql back online.

how can I get these database files to fully work on a new server?

MySQL Monitor Shows MySQL As Offline When It's Not

Jan 15, 2007

I've been racking my brains with this problem for the last couple of months and have made zero progress. I've asked a lot of people if they know what might be wrong here, but none of them have any idea.

Basically, the problem is that any sort of service monitor I put on my server shows MySQL as being down/offline, even when I know for sure it's up and running perfectly fine. All other services report a green light.

The mysqld service is running on port 3306, which is open both inbound and outbound on my APF config, so as far as I can tell it's nothing to do with the firewall (I won't rule that out though).

The other odd thing is that MySQL shows a green light within WHM, but not anywhere else.

Does anyone know what might be wrong here? Am I missing something entirely fundamental and obvious?

Weird MySQL: User/pass Stops Working After A While

Mar 29, 2009

I am having a very strange problem with 2 different cPanel accounts on a server with 500-600 accounts. For some reason after a day or two the mysql username/password stops working. We have tried changing the MySQL user and the password with no success. The log does not indicate that the MySQL password was changed in any way. Only these 2 accounts are affected and this problem occurred at least half dozen times each.

Again: these are two different accounts with 2 different MySQL users that after a while stop working (I am unable to determine if they stop working at the same time b/c they belong to different customers). When we reset the user (with the same pass) it works for a day or two. I have checked to connect not only from PHP but also from shell when it's down: it also doesn't work so this is a pure MySQL problem.

Also on the server we have Fantastico.

Uninstall MySQL 3.23 And Install MySQL 5.0

Mar 28, 2007

I've rented a dedicated server that comes with Red Hat Enterprise Linux 4 and MySQL 3.23 but I need at least MySQL 4.1 or higher. My knowledge about GNU/Linux is very limited, so I've read some documents at mysql.com and now I think I have to follow these steps:

1. Uninstall MySQL 3.23 with this command line:
shell> rpm -e mysql-*.rpm

2. Install the server and client RPMs of MySQL 5.0:
shell> rpm -i MySQL-server-VERSION.i386.rpm
shell> rpm -i MySQL-client-VERSION.i386.rpm

How To Fix Mysql Backup

May 25, 2009

I have some NAS storage to do backups to with my dedicated hosting provider. I setup automatic daily backups with WHM to backup the databases and accounts. The server is hosting one site. When it does the backup, it does a mysql dump, and essentially takes the site down for the whole time it is doing the backup because nobody can connect to the database while the dump is happening. Is there a better way to do the backup so that this won't happen, whether it be a different method of backing up to NAS, or just not using NAS at all and using some other method.

MYSql Backup From V5 To V4

Jan 19, 2007

I am trying to backup and restore a database and seem to be running in to the following errors.

ERROR 1005 (HY000) at line 29: Can't create table './tcadmin/tc_bandwidth_type.frm' (errno: 121)

Source machine
Windows Server 2003
mysql 5.0.11

destination machine
RHEL 4.x
MYsql 4.1.20

I think it is the way I am backing up the database that is the real problem

I have checked the compatibility mode option in the administration panel for backup, run full backup, and lockled the tables and still I get the error.

I have done some research and I think there is a command line I need to run to make it compatible with mysql 4.x systems but nothing seems to be right that I am doing. Can anyone here offer some insight to what the problem might be?

MySQL Backup - How Do You Do It Right

Jun 28, 2007

today when the indata1 file got corrupted and I found out that rsync was NOT backing it up. I had thought the rsyncing the life files was good enough and that if I had to restore I could just run mysqlrepair and get everything back.

what is the RIGHT way to backup MySQL databases and do I want to somehow get rid of the inoddb stuff?

Incremental MySql Backup

Apr 14, 2009

Does anyone have experience in backing up mysql incrementally? From what I've read in the docs it's possible using the binary logs but I haven't been able to find a good resource on how to make this work.

I have a database that is over 5GB. There are a few Myisam tables that are insert/select only and one innodb table that receives updates/deletes/selects/inserts.

Ideally I wouldn't have to backup the 5GB every night, I'd prefer to only get the items that have changed. If I could make this work, then I could also get backups more often rather than once a night.

Backup MySQL Intensive VPS

Jun 12, 2009

I have two VPS's which run a single MySQL intensive site. The first VPS runs cPanel and has about 50 databases, 200mb each. Second has another 30 databases, of the same size.

What would be the best method to backup this website daily?

At Current;
I use automysqlbackup to backup all the databases at midnight (this crashes the VPS's for about 10 minutes each night). This dumps each one into a zipped file.

Then the rsync copies the changed files (forum attachmenets, cpanel changes etc(whole server)) to an off site location.

Are there any easier ways to do this? The databases are most important!

Backup In CPanel/WHM Without Mysql

Mysql Backup, 2 Different Sizes Why

Jan 18, 2008

Using Cpanel:

-I went to backup option and downloaded the database backup. 951kb

-I went into phpadmin and checked addrop table. 1.5m

Using SSH:
command mysqldump -u myusername_usernam -pmypassword myusername_name > /home/name/backupz/name.sql = 949k

3 different sizes, I would figure maybe adding droptables would amount to higher size but the first way and third way i use, how come there is a size difference of 2kb?

Which is the right way to backup mysql database safely?

Backup MySQL Databases On PC

Jul 20, 2007

I host with hostgator and I was wondering if there are any software programs or services, or even something in my cpanel that can automatically grab my MySQL databases and everything on my server and make a backup on my personal PC?

I know I can manually do this, but I would like something that automatically does it once a week or something to insure my clients data is always backed up.

Host That Allows MySQL Backup/restore Via FTP

Sep 24, 2009

I need to get the h3ll away from Godaddy, fast!

However, my site has a large MySQL database (200 megabytes) and it's impossible to backup or restore via phpMyadmin. Godaddy has a feature on their control panel, where you can restore/backup your MySQL database to a special diretory on your web http file space, which you can upload/download vis FTP. I use this alot.

Is there any other web hosting company that offers such a feature? I haven't seen this anywhere except on Godaddy.

As to why I need to get away from Godaddy:

Basically what they did was, my site was getting too much traffic (even though it's still well under Godaddy's advertised limits for that plan)... so they sent me an email that says:

"Your site is using too much server resources. We have moved you to a new server to protect our other customers. Please identify steps to reduce your site traffic and contact us."

They moved my site to what is, apparently, a punishment area (Godaddy Hell) where all the high volume sites go. It is so extremely slow, my site might as well not exist... it is inaccessible to my visitors for all intents and purposes.

Secure MySQL Backup Script

Jul 29, 2008

Is there a method of running a back-up script,as root, using MySQL, without passing or storing the root password in the clear?

I have tried OpenSSH with a nologin option using certificates, but I still have problems. I need to run it as a cron job every so often, (without specifics) securely.

I understand I can use another user, other than root, with read-only, but I need to back up the whole db at once, not specific users db's.

Backup And Restore Mysql Databases

May 10, 2008

I have a corrupted VPS, and have some mysql databases on it.

I want to backup databases and restore them on the new server.

Cpanel service is down on the vps and I cannot transfer accts.

Is it possible to do so ?

1- Zip or Tar the username folder in /home dir.

2- zip or tar the database name in /var/lib/mysql folder

Either by SSH or File manager trough HyperVM

Then transfer files some where safe...

When vps is rebuilt, restore the archives and databases to
the folders I have backed up before rebuilt.

There are also some accounts on a terminated vps that there is only an image of the vps available so, I only can tar files using a jailed shell account, move to the new vps and untar them.

how to do it and avoid database problems.

MySQL Backup Multiple Databases

Feb 8, 2008

My site is databases driven and runs on around 15 mySQL databases. Im wanting to download a local copy of these databases daily, however, if i try and back them up via cPanel (on a WHM VPS) they give me blank files. Each databases is around 55mb and growing. I can back them up one by one via phpmyadmin, it just takes around 5 minutes per database. Meaning around 40 minutes per night..

Is there any solution for having a script downloading them automatically so i can download them via ftp? I've tried [url].htm but it gives me blank files.
