  • Backing up a 22 GB MySQL database daily

    - by unknown (yahoo)
    Right now I am able to do the backup using mysqldump. But I have to take down the web server AND it takes around 5 minutes to do the backup. If I don't take down the web server, it takes forever and never finishes + the website becomes inaccessible during the backup. Is there a quicker/better way to backup my 22 GB and growing database? All the tables are MyISAM.

  • innodb memory usage mysql

    - by Tiddo
    I have a small vps, with only 256mb of ram, with maximum burst up to 512mb. When I configure my vps without innodb, it only uses 130 mb of ram, so that is no problem for me. But when I turn on innodb, The memory usage grows to about 300-400 mb. Is it possible to run innodb such that I won't exceed the 256mb? preferably I don't want to use more than 100mb for innodb. I already came across some sites which said I could limit the memory usage, but if I limit it to only 100mb will the db run well enough? (compared to for example the MyISAM storage engine) If 100mb is to little memory for innodb, can you recommend me any other storage engine which supports transactions?

  • MySQL Non Index Queries Analysis

    - by Markii
    I'm using the log queries not using index but it logs all that use indexes but just more advanced or using IFs. Is there a parser or a program out there that can analyze the log and give me a literal output of saying "table.column should be a index" Thanks

  • CentOS not allowing remote MySQL connections

    - by nd8ad
    When assigning a user from a remote IP to connect to a database it is saying that it's failing to connect. It is also failing to connect with root so something is wrong. Bind IP is off and I have also tried disabling iptables, still no dice. Port 3306 is forwarded. I'm running on Centos 5.6, using phpmyadmin, but I have also tried to assign the user via the commandline and create a new database, still not working. Been googling and troubleshooting for hours now, no dice.

  • Auto-restart mysql when it dies

    - by Los Frijoles
    I have a rackspace server that I have been renting to run my personal projects upon. Since I am cheap, it has 256Mb of RAM and honestly can't handle alot. Every once in a while, when there is a sharp uptick in traffic, the server decides to start killing processes and it seems that mysqld is a popular one for it to kill. I try to visit my site and am greeted with the message that there was an error establishing the database connection. Inspection of the logs reveals that mysqld was killed due to lack of memory. Since I am still as poor as I was yesterday and don't want to upgrade my rackspace VM's RAM, is there a way I can tell it to automagically restart mysqld when it dies? I have a thought to use something like crontab, but alas, I don't know exactly what to do there either. I guess I am product of the "Linux on your desktop" generation since I can do most things on my desktop and laptop (which run Linux almost exclusively), but still lack a lot of server administration skills for Linux. The server runs CentOS 6.3

  • Move MySQL master

    - by Noodles
    I currently have a master db server (lets call it db1) and 6 slaves (slave1-6). I've setup a new server (db2) as a slave of db1 and it's in sync. I want to change all the slaves to use db2 instead of db1, but with minimal downtime/data loss. At the moment the only way I can think of doing it is shutting down our website (so data stops being written to db1), waiting until all the slaves are up to date, flush logs on db1, shut it down. Reset master on db2, change all slaves to point to db2 with log position = 0. Is this the right way to do it or is there a way to do it without taking the site offline?

  • How do I mirror a MySQL database?

    - by user45745
    I'm running two load balanced servers for one website, and I'd like the databases to be synchronized. Queries may be run on either of the two servers because they are both production sites, so the replication can't just work one way. It doesn't have to be in real-time, just fairly accurate so people don't notice a difference when they get switched to a different server.

  • Realtime website slowness (PHP/MYSQL)

    - by 3s2ng
    We got a website with realtime transactions. The past few days we experienced some slowness during a period of time. Usually the slowness last for 5 minutes. And also during the slowness we noticed that sometimes we can not connect to SSH and FTP or sometimes very slow to connect to those services. Currently we are trying to identify the issue. We already setup database monitoring tool. Now are about to signup with pingdom.com My question is. If the website is too slow due to the database (table or row lock) will it affect the other services like SSH and FTP? Does the ping correlates the page load and the connection between my PC and server? Thanks, Mark

  • How to filter a mysql database with user input on a website and then spit the filtered table back to the website? [migrated]

    - by Luke
    I've been researching this on google for literally 3 weeks, racking my brain and still not quite finding anything. I can't believe this is so elusive. (I'm a complete beginner so if my terminology sounds stupid then that's why.) I have a database in mysql/phpmyadmin on my web host. I'm trying to create a front end that will allow a user to specify criteria for querying the database in a way that they don't have to know sql, basically just combo boxes and checkboxes on a form. Then have this form 'submit' a query to the database, and show the filtered tables. This is how the SQL looks in Microsoft Access: PARAMETERS TEXTINPUT1 Text ( 255 ), NUMBERINPUT1 IEEEDouble; // pops up a list of parameters for the user to input SELECT DISTINCT Table1.Column1, Table1.Column2, Table1.Column3,* // selects only the unique rows in these three columns FROM Table1 // the table where this query is happening WHERE (((Table1.Column1) Like TEXTINPUT1] AND ((Table1.Column2)<=[NUMBERINPUT1] AND ((Table1.Column3)>=[NUMBERINPUT1])); // the criteria for the filter, it's comparing the user input parameters to the data in the rows and only selecting matches according to the equal sign, or greater than + equal sign, or less than + equal sign What I don't get: WHAT IN THE WORLD AM I SUPPOSED TO USE (that isn't totally hard)!? I've tried google fusion tables - doesn't filter right with numerical data or empty cells in rows, can't relate tables I've tried DataTables.net, can't filter right with numerical data and can't use SQL without a bunch of indepth knowledge, not even sure it can if you have that.. I've looked into using jQuery with google spreadsheets, doesn't work at all either I have no idea how I'm supposed to build a front end with my database. Every place that looks promising (like zohocreator) is asking for money, and is far too simplified to be able to do the LIKE criteria or SELECT DISTINCT stuff.

  • How do you setup Postfix/Dovecot/MySQL to not look for local accounts?

    - by thiesdiggity
    I am having an issue with one of my Postfix/Dovecot mail servers and I'm unsure how to fix the problem. I will try to explain it in detail, here it goes: I have an Ubuntu server setup using Virtual hosting with Postfix, Dovecot and MySQL. We have one domain setup as a virtual domain, for this example I am going to use mail.example.com. Under that domain we have one email address. I have another server (MS Exchange) setup using another one of my sub-domains, ex.example.com. The problem is that when I SMTP into the account on mail.example.com and try to send an email to an account on ex.example.com, I get the email returned back to us with an "unknown host" error. Now, I know that the mail.example.com server can resolve the ex.example.com domain because I can ping/dig while SSH'd into it. I can also log into Postfix via Telnet and send an email to an ex.example.com mailbox. I'm guessing that it has something to do with Postfix/Dovecot looking locally for the domain in the virtual domain list because of the tld domain (example.com)? If that's the case, how do I get Postfix/Dovecot to only look locally for the entire URL (mail.example.com) and if it doesn't find it, send it to the correct server by looking up the MX/A records (which I know exist and are setup correctly)? I have been working on this all day and any guidance would be GREATLY appreciated! Thanks for your time!

  • PHP Code (modules) included via MySQL database, good idea?

    - by ionFish
    The main script includes "modules" which add functionality to it. Each module is set up like this: <?php //data collection stuff //(...) approx 80 lines of code //end data collection $var1 = 'some data'; $var2 = 'more data'; $var3 = 'other data'; ?> Each module has the same exact variables, just the data collection is different. I was wondering if it's a reasonable idea to store the module data in MySQL like this: [database] |_modules |_name |_function (the raw PHP data from above) |_description |_author |_update-url |_version |_enabled ...and then include the PHP-data from the database and execute it? Something like, a tab-navigation system at the top of the page for each module name, then inside each of those tabs the page content would function by parsing the database-stored code of the module from the function section. The purpose would be to save code space (fewer lines), allow for easy updates, and include/exclude modules based on the enabled option. This is how many other web-apps work, some of my own too. But never had I thought about this so deeply. Are there any drawbacks or security risks to this?

  • Zend Server with xampp MySQL

    - by Vincent
    I am running Zend Server,Zend Studio (Trial versions) on Ubuntu 9.10. I am also using xampp to do most of my development. I plan to use Zend Server only to do URL profiling to know function level performance of my code. Is it possible to configure Zend Server to use XAMPP's MySQL database instead of installing a new mysql instance for Zend Server? Thanks
