I have one doubt, is copying /var/lib/mysql is a good alterntive to mysqldump?.
Because i use rsync to copy /var/lib/mysql for back up without dumping the database. I use rsync to do differential backup up so that it copies /var/lib/mysql to /var/tmp every one minute.
we had a CENTOS 5.5 x86_64 machine with 8ered with MySQL 5.0.91-community.Currently we had a very high number of Created_tmp_disk_tables (31k in 4,5 hours!!!).I've read suggestion that we need to increase tmp_table_size, and we've set tmp_table_size to 64M, but this drupal modul's query still cause mysql create tmp table on disk
Code:
SELECT DISTINCT node.nid AS nid,
comments.subject AS comments_subject,

We are running an adserver with mysql as the database. We backup the database every hour and lately noticed that ads doesn't get delivered at the time of backup. The database size is 1.2 GB in which a single table ifself is 1.1 GB. Googling around the problem says this may be due to lock table feature in mysqldump and disabling it might solve the issue but i'm afraid whether this would be a problem. Can anyone please explain what lock table means and will it be a problem if i disable it or may be any other alternative solutions/assitance (other than master/slave or replication since we cannot afford it at this time) would be really helpful.
View 1 Replies View RelatedI have some tables that contain special characters from different languages like German, Italian, Russian, Spanish etc. They are stored and displayed correctly.
When want to backup my DB like "mysqldump -h localhost-u root -p dbname > dbname.sql" the special characters are lost, they are not correctly stored nor displayed in the sql file. This means there is no possible restoration.
I think this goes here, but I'm not sure. I decided that XAMPP had been troublesome enough. MySQL never worked. So I decided to instal the LAMP stack offered by YaST. I went about installing it thinking that it would all work. But it seems that I was wrong. So I try to start mysql, and here's what I get:
Code:
the-matrix:~ # mysql start
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) or
Code:
the-matrix:~ # rcmysql start

I noticed in phpmyadmin that we can export a database in type update. Indeed we have update... in place of insert.... is there anyone know if it possible by a command line or by a simple PHP code ?

I have installed Mysql in Ubuntu 9, for the use of roundcube database.After installing iam getting the error like this
* Stopping MySQL database server mysqld [ OK ]
* Starting MySQL database server mysqld [ OK ]
* Checking for corrupt, not cleanly closed and upgrade needing tables.
So because of this in the roundcube configuration its giving the error message that MYSQL is not installed. So Kindly give me a idea how to solve this.
I'm having problems connecting to the mysql database on my system. I first noticed this when I was trying to set up the program anymeal. I subsequently tried using MySQL Administrator (mysql-admin), but had no luck. It gives my the following feedback:

Click the 'Ping' button to see if there is a networking problem. I press the ping button, and it seems to connect.

I've been attempting to set up a LAMP for local web development, which meant installing mysql-server. But now have a problem when trying to run mysql, I get:-

When trying to downgrade mysql-server I saw that there are dependency problems between the various modules (but can't recall which). But whichever route I truied the results are always the same.
Thought about trying XAMPP but I note that even has it's problems, is there any way I can get a lamp set up on FC14, or must I give it up as a bad job.
Howver, just been trying to again to fix the problems with downgrading mysql and get:-
Error: Package: mysql-server-5.1.55-1.fc14.i686 (@updates)
Requires: mysql(x86-32) = 5.1.55-1.fc14

I was having issues with MySQL Server and uninstalled it. I still have my databases at /lib/var/mysql.
My question: if I install MySQL Server (same version, 5.1) again, will it delete my databases, or will they still work?
How can I really, really remove everything related to mysql / mysql-server. I read and tried all kinds of things, but on every reinstall there is still old mysql stuff there, for example an existing password. Even resetting the password does not help.
Reason of removal: it looks like the mysql setup is really corrupt, so I want to remove, and then do a fresh install. Running Ubuntu 11.04 64-bit
sander@R540:~$ sudo apt-get purge mysql-server

I installed mediawiki the other day and went with the default innodb option. However a week later something went wrong. And since I have scripts that nightly backup /var/ I just copied the backup of /var/lib/mysql/wikidb/ (as I've done with MyISAM). Then when I connect the wikidb database. I can see the tables (via "show tables"), but when I do any query with them (check table X, select * from X) I get:
Code:
Table 'wikidb.X' doesn't exist I've since read that can can't just copy the database directory like MyISAM, and there appears to be no way that I can find to restore or fix Innodb, without a dump of the data. And I never got a chance to do a mysqldump of the data. So has anybody got any idea how I can at least view the "page" table from the files I've backed up in /var/lib/mysql/wikidb/ ?
I just configured a complete Cent OS 5.2 system for use as a web server. I can configure Apache and PHP but MySQl seems to be causing some issues -

user=mysql
# Default to using old password format for compatibility with mysql 3.x

I am using CentOS5 and installed the MySQL for server during the installation. I can set up and use MySQL databases. But I cannot make it startup everytime the server restarts. And quite a lot of methods need this folder "support-files/mysql.server", while my set up cannot find this. I am wondering if my installation of the MySQL for server is complete or not.
View 4 Replies View RelatedI have a LAMP website with mysql backend with InnoDb engine for tables.I would like to be able to use mysqldump to take periodic dumps of the database - WITHOUT having to stop the mysql server (i.e. shutting down the website) for the duration of the backup. not even in the mySQL documentation. A lot of mention is made about mysqlhotcopy, but that only works for IMSAM tables - and is therefore of no interest/use to me.Does anyone know if (how?) I can use mysqldump to take a copy/dump of a database that is still being used?.A link to the official documentation would be very useful, since I want to make sure that I get this absolutely right.I am running on Ubuntu 10.0.4 LTS
View 4 Replies View RelatedI know little if anything about svn, so need your assistance. I have a linux server running svn. I have a Windows server running svn. First, I'm looking for a way to copy an svn repository from the linux server to a new Windows server repository. I've looked for how to do this on the Internet and within the Apache.org website(which is now the maintainer of SVN).
I haven't found anything on a very granuler way to copy a repository from one O/S to another other than folks say it can be done. Not how.
Second, is there a way to automatically do this on a regular basis? I see the manual process of svnadmin dump and svnload. Also there is a manual process of svnadmin hotcopy.

View 3 Replies View RelatedI would like to have my backup script that I am writing to create a sql dump of my database and go directly into a tar file. Does anyone know how I could do this with one command?
To be more clear I would like to go from
mysqldump -u xxxx -pXXXXX tablename> currentbackup.sql
tar -czvf backup-XXXXXXXX.tgz currentbackup.sql
rm currentbackup.sql
To a single command somehow. Does anyone know how I could accomplish something like this?
Is it possible to compress the mysqldump output into say db_backup.sql.tgz. Then add that to an existing archive e.g. backup.tgz in one command or on the fly to save space and deleting it?
