Server :: Turns Out The Drive That Stores The Mysql Databases Has Gone Missing?
Aug 2, 2011
Rebooted my server after some funky stuff started happening with mysql. Turns out the drive that stores the mysql databases has gone missing. I did an fdisk, and the partition table is gone. I used gpart to see if there were any partitions available & there were -- two + one swap. Can you help me put this back together I know very little about reconstructing a table to use... Here is the output of what I've talked about...
I need to move mysql databases from my hard drive which is currently in external box. I can't boot the drive since the laptop is down. Nothing of the distribution on the drive is missing. I just need to know which files/folders copy to my new computer to have all databases running. Old computer ran on Dreamlinux (Debian-based). I'm currently running Ubuntu 9.10.
After changing the administrator password only information_schema and test databases are shown in GUI tools (webmin or mysql administrator GUI tool). After the error I restored the password to the old used
if I use mysql in terminal, and use show databases; I can see the 7 databases that I have.
I aslo cannot access to any field using GUI tools (cannot acces to database permissions, or MySQL Server Configuration, host permissions or MySQL system variables). The error is:
DBI connect failed : Access denied for user ''@'localhost' to database 'mysql'
Do you know how to restore the view/access to databases?
I have installed mysql ,php ,apache,phpmyadmin i have create a forum on mysite check it on[URL]..Now i have create a database with name login and then i create a table with name loginn ..After that in loginn table i create colums with name username (data type=varchar),and password(data type=int);i want when someone entered username and password in my sql ,it goes to database and userconnect to next page as we generally do in orkut or other social sites;I dont know how to connect with php with mysql and how to do it whole
Quick searches did not bring forth any standard solution.
I have installed Ubuntu Server 10 (x64) using LVM with two disks (this is a Virtual Machine on VMWare ESXi4)
During install I selected only disk 1, and LVM guided Installation Added LAMP and SSH
Server gives only a text mode configuration, great if you are a linux guru, but I am not so it took a bit to find a stripped down GUI. None could be found but I did the following:
I have a laptop and a desktop PC, both running Ubuntu 10.04 and both are configured the same way. I am using Unison-gtk to sync the data between both computers... This works for everything... except for my mysql databases. Any way to simply sync my mysql databases on both computers. Right now I need to do this table-per-table... and it is quite long to proceed like this. What I need is a script or a program (open and preferably free) that would just compare both databases (all the tables) and sync them either by updating existing tables or by creating them. This should work both ways... obviously. I could write a script for this, but I am sure there already is something for this out there.
How do I restore MySQL Databases from an old hdd with Ubuntu on it which won't boot? Information below is not necessary just explaining how I ended up in this situation. Today the harddrive crashed on one of my development servers and I have no recent backup of the MySQL databases on the server.
The stuff on the server weren't horrible important but it would still be nice if I were able to recover some of the files. This is the thing, I don't think the harddrive is entirely dead because it comes to a screen saying harddrive error something enter to continue then it says GRUB in the upper left corner before the computer crashes/reboots.
So I installed Ubuntu server on a new HDD and now I want to attempt to recover the databases from the old HDD by mounting it in Ubuntu but before trying I would like to know who one does that. As I've understood it's a bit more complicated then one might thing because MySQL uses binaries and not plain-files.
I know very little about MySQL, but I've got some users that need it for testing on a Linux server.So I had set it up a while back, but now I'm running into some small problems.Right now, each user has his own database that I created and can do whatever with it. Each user only sees their own database.I didn't want them to be able to create new databases at all, but they can and when they do anyone can see them.
EDIT(Apparently they can only create databases beginning with the word "test" in the name)
I need to either:
1) Stop them from creating new databases (without affecting their ability to interact with the existing database)
OR
2) Make it so that when they create a database, only they have privileges on it and only they can see it (except mysql root of course).
Anybody know the statement to set these kinds privileges up?
EDIT: pfft... I've a read a bit more and realize that this is an intended part of the installation.
EDIT2
I'd still like to remove the ability to make test databases.
EDIT3:Ok, for reference this is how you prevent users from making and using test databases:
shell> mysql -u root -p Enter password: (enter root password here) mysql> DELETE FROM mysql.db WHERE Db LIKE 'test%'; mysql> FLUSH PRIVILEGES;
Relational databases usually have their data over in /var/lib/something. Users are in /home (with data in /var/www). How can I apply a single total disk space quota across all of these independent software systems (file systems, RDBMS, etc.)?
P.S. There's a bet going on around me as to just how awesome SU is. Let's see what you've got.
I just installed a MySQL server but for unknown reason im not able to set a root password. CentOS 5.4 - 2.6.18-164.9.1.el5PAE MySQL Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1 # yum install -y mysql mysql-server php-mysql # service mysqld start # mysql -u root ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
I am having no luck configuring ProFTPd on a Debian Lenny production server we use to host our MySQL databases and a few websites. I had originally set it up so I could login and manage our internal sites, but I have the need to allow a few clients in to access their sites that we host. I am trying to root the users in their site directory, which would be "/sites/www.whatever.com/".
It just hit me while typing this. Is it possible to create a user without a shell to prevent login via SSH and set the home folder to /sites/whatever instead of /home/username? That would allow me to continue operating with my current configuration and root them in their site while preventing SSH logins.
I transfered some mysql databases from an 8.04 partition to a 10.04 partition. They wouldn't open because the ownership & group was root:root since I transfered them as root. I looked at the original ownership of the files on 8.04 & found they were all "sane:124 ". I changed everything to mysql:mysql on the 10.04 partition & everything works O.K. now but I have no idea where that owner & group came from.
Two things I don't understand:
1 -Why I had to change ownership from root:root when I was logged in as root in mysql & the databases didn't show up? 2 - Where did the original "sane:124" ownership come from?
As we have planned to implement jboss web server. i am curious gather some information about it.My question is where jboss stores the deployed file. Because jboss server starts with no error.but i cant able to access my application.Its showing 404 error.I just want to know the path where jboss stores the deployed file or the any log files that tells the story.
suspend has always worked fine with 11.04 and now it stopped working a few days ago. How can I figure out what is going on? The display turns off but the computer never turns off and the only way to bring it back is to hold the power button down and then start it back up.
I've got several servers running RedHat4 ES, alongside several Windows 2003 servers with MS SQL on them.
Is there a MS SQL Client for Linux so I can connect to the SQL Server databases?
I'ev got Oracle running as well, and I can back these up from my linux boxes easily as there is a Linux ORacle client. I'd like to do the same with MS SQL, so I have one central location doing my database backups .
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 Starting service MySQL warning: /var/mysql/mysql.sock didn't appear within 30 seconds chmod: cannot access `/var/run/mysql/mysqld.pid': No such file or directory
I just found that PMON and SMON are running (i.e., showing in the output of ps -ef | grep -i [o]ra)but when I check MMAN (used for internal database tasks), nothing comes up:
Code: ps -ef | grep -i [m]man Is that okay or could there be some problem?
So, what are the essential processes of an Oracle Databse that we must check for their status to make sure that the Oracle Databse is up and running fine? What steps do you usually take to validate an Oracle Databse on a Unix / Linux (Production) Server (specifically immediately after a CR has been worked upon)?
i am using liferay5.2(mysql included in the download pack) on fedora. while liferay is working fine but i cannot connect to mysql.i am getting the error
[ [root@localhost ~]# ln -s /var/lib/mysql/mysql.sock /tmp [root@localhost ~]# /etc/init.d/mysqld start Timeout error occurred trying to start MySQL Daemon.
[code]....
i didnt find the mysql.sock file in the location /var/lib/mysql/mysql.sock. i cannot find the portal-ext.properties file also to make intial settings.
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:
Code:
Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
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:-
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
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:-
I've mysql server running ,and i have one single database. everything is working fine but I cant find .MYD and .MYI of one of my tables .and now when i tried to make a backup mysqldump fails because .MYI et .MYI are not found. I tried locate my_table.MYD my_table.MYI BUT no chance
I'm trying to setup wordpress on my server, which of course I need mysql for. I setup a database the other day, which worked perfectly, but I had to start again as I put some information in wrong. Now, I can create a database fine, but when I run
Code: GRANT ALL ON wordpress.* TO wordpress@localhost IDENTIFIED BY "password"; I get the output:
