recently I had problems with backing up my ~150mb database through PHP. And I know some people are backing their databases to a dump file through terminal.
My database contains UTF-8 and other characters. I have tried simply dumping with mysqldump but I doesn't seem to work, when restoring all the characters are messed up.
Is there any command to tell that the database is UTF-8?

to change a mysql database and all its tables to a utf8 charset and collation, however I'm not sure specifically which one I should use. We are currently using latin1_general_ci.
On a forum I've noticed that in a couple of posts I made, sometimes characters such as the euro sign €, and the German ß get converted to question marks.
Being an English forum we don't often have members use these characters but we'd like them displayed correctly when they are.
I don't really know much about character sets and such, but I understand that they contain different characters and treat them differently in comparisons and sorts etc. So which of the following should I be using?
utf8_bin
utf8_general_ci
utf8_unicode_ci
I was leaning towards unicode, but I don't know what the differences between them are. Can anyone advise us on what to use?
This is for MySQL 4.1.22 btw.
I'm certain the problem is not with my browser, and the characters are typed from the keyboard, not copied and pasted from word docs. A charset is specified by a meta tag in the header too.
I have a vbulletin (3.7.2) board with many mods installed (nearly 70) without a problem.
However, upon installing one new mod I got a database error stating:
MySQL Error : Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (latin1_general_ci,IMPLICIT) for operation '='
How do I change ALL tables in one shot (or sql query via phpmyadmin) from the two different collations to utf8?
Also, is utf8 suggested or better than latin1?
I have enabled the backup rotation of some websites to my "Personal FTP Repository", the problem is that Plesk is unable to do it due this error:
Code:
Unable to rotate dump: The dump rotation is failed with code '121' at /usr/local/psa/admin/bin/plesk_agent_manager line 1041.
I read here [URL] .... that it should be solved but I have the version 12.0.18 Update #33, why does it persist?
i been trying to move my server.. But mysql database is quite big and restoring takes ages 10 12 hours.. is there anyway i can make it quick because database dump takes 10 15mins but restore takes 12hours and it should be a way to make that quick

I'm using a cpanel based server, but I can't get this to work.
It requires I be in a directory I figure (this step isnt included)
so I type cd /home/username/public_html/
And then i follow the commands. but it doesnt work.
Basically i need to take a mysql database that I uploaded to my directory, and load it back into a database. :@
I have a problem getting mysql to start, so I am planning to setup a new server and move all the mysql databases to a new server.
The problem is I normally get mysql databases when mysql is running by using mysql command lines. Now that I cannot start mysql, I cannot use that method.
Is there a mysql directory that contains all the mysql databases for me to tar it up and untar it on a different? If there is a directory that contains all the mysql databases, do I need to exclude some files/folders so it doesnt conflict with the files/folders on my new mysql server?
we have whm in my server

what steps procedures need to be done to keep your database as safe as possible from the hackers. Anyway to be alert when someone got into your db and try to dump, alter your database?
View 4 Replies View RelatedI got this weird problem with my VPS which has MySQL 4.1.22 running on it. Everything works fine for sometime and then out of a sudden, it stop recognizing the mysql users and refused to allow my PHP scripts to access the database.
It seems that I needed to restart mySQL server to resolve the issue. Then out of the blues, the same problem occurs.
I am running Cpanel on a VPS and there isn't any overloading as the database access is pretty light on my 512mb VPS.
I contacted my web host about the issue and it seems like all they do is to restart the mySQL. This cannot be a solution as it happens at least once or twice a day depending on how soon I could catch the problem.
All the time this problem occurs, the MYSQL Server is still active and working. I can even access it through PHPMyAdmin but not through the scripts.
I just added an hourly crontab so as to restart the MySQL server as a stop gap.
What is the recommended method of backing up big MySQL database of size 2 GB ?

I checked the table, it is fine, but can't do the backup.

ways to improve the database performance in the situation when I have to modify a large table (several million rows), by e.g. adding a column. Currently this would take several hours which is too slow. The bottleneck is disk I/O. I am considering either partitioning the table over several innodb files on several disks, or going to a RAID-5 or RAID-10, it this will give me better write performance.
The database is 130GB large, and the problem table (which I make period changes to) is the largest table on the server. I cannot have downtime of 3 hours each time I make a change and adding blank fields (to be used later, when a new field is needed) is not an option.
Each time I add a column, the cpu goes into high (80%) io wait state for about 3 hours.
I have a hack which would allow me to split the large table into multiple smaller tables based on some criteria (for example, forumID or such). Here are a couple of things but would like to know which is best, and am open to new ideas. The ideas so far:
1. Split the table into 3 or 5 smaller tables each on it's own disk. The disk IO would then not be so bad, and it might only take 1 hour to perform the table change. But this might not work because the changes to the database (as in adding a column) might be serial, meaning only 1 disk is being written to at a time. (Then again, maybe it will work if I launch 3 different scripts, one to update each table at once).
2. Do RAID 5 or 10, and have 3 or 5 disks. This again might not help at all because of the above issue with MySQL writing serially.
I am using latest MySQL 5.0.45 with InnoDB engine on Debian etch Linux
