  • MYSQL not running on Ubuntu OS - Error 2002.

    - by mgj
    Hi, I am a novice to mysql DB. I am trying to run the MYSQL Server on Ubuntu 10.04. Through Synaptic Package Manager I am have installed the mysql version: mysql-client-5.1 I wonder that how was the database password set for the mysql-client software that I installed through the above way.It would be nice if you could enlighten me on this. When I tried running this database, I encountered the error given below: mohnish@mohnish-laptop:/var/lib$ mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) mohnish@mohnish-laptop:/var/lib$ I referred to a similar question posted by another user. I didn't find a solution through the proposed answers. For instance when I tried the solutions posted for the similar question I got the following: mohnish@mohnish-laptop:/var/lib$ service start mysqld start: unrecognized service mohnish@mohnish-laptop:/var/lib$ ps -u mysql ERROR: User name does not exist. ********* simple selection ********* ********* selection by list ********* -A all processes -C by command name -N negate selection -G by real group ID (supports names) -a all w/ tty except session leaders -U by real user ID (supports names) -d all except session leaders -g by session OR by effective group name -e all processes -p by process ID T all processes on this terminal -s processes in the sessions given a all w/ tty, including other users -t by tty g OBSOLETE -- DO NOT USE -u by effective user ID (supports names) r only running processes U processes for specified users x processes w/o controlling ttys t by tty *********** output format ********** *********** long options *********** -o,o user-defined -f full --Group --User --pid --cols --ppid -j,j job control s signal --group --user --sid --rows --info -O,O preloaded -o v virtual memory --cumulative --format --deselect -l,l long u user-oriented --sort --tty --forest --version -F extra full X registers --heading --no-heading --context ********* misc options ********* -V,V show version L list format codes f ASCII art forest -m,m,-L,-T,H threads S children in sum -y change -l format -M,Z security data c true command name -c scheduling class -w,w wide output n numeric WCHAN,UID -H process hierarchy mohnish@mohnish-laptop:/var/lib$ which mysql /usr/bin/mysql mohnish@mohnish-laptop:/var/lib$ mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) I even tried referring to http://forums.mysql.com/read.php?11,27769,84713#msg-84713 but couldn't find anything useful. Please let me know how I could tackle this error. Thank you very much..

  • MySQL Config File for Large System

    - by Jonathon
    We are running MySQL on a Windows 2003 Server Enterpise Edition box. MySQL is about the only program running on the box. We have approx. 8 slaves replicated to it, but my understanding is that having multiple slaves connecting to the same master does not significantly slow down performance, if at all. The master server has 16G RAM, 10 Terabyte drives in RAID 10, and four dual-core processors. From what I have seen from other sites, we have a really robust machine as our master db server. We just upgraded from a machine with only 4G RAM, but with similar hard drives, RAID, etc. It also ran Apache on it, so it was our db server and our application server. It was getting a little slow, so we split the db server onto this new machine and kept the application server on the first machine. We also distributed the application load amongst a few of our other slave servers, which also run the application. The problem is the new db server has mysqld.exe consuming 95-100% of CPU almost all the time and is really causing the app to run slowly. I know we have several queries and table structures that could be better optimized, but since they worked okay on the older, smaller server, I assume that our my.ini (MySQL config) file is not properly configured. Most of what I see on the net is for setting config files on small machines, so can anyone help me get the my.ini file correct for a large dedicated machine like ours? I just don't see how mysqld could get so bogged down! FYI: We have about 100 queries per second. We only use MyISAM tables, so skip-innodb is set in the ini file. And yes, I know it is reading the ini file correctly because I can change some settings (like the server-id and it will kill the server at startup). Here is the my.ini file: #MySQL Server Instance Configuration File # ---------------------------------------------------------------------- # Generated by the MySQL Server Instance Configuration Wizard # # # Installation Instructions # ---------------------------------------------------------------------- # # On Linux you can copy this file to /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options # (@localstatedir@ for this installation) or to # ~/.my.cnf to set user-specific options. # # On Windows you should keep this file in the installation directory # of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To # make sure the server reads the config file use the startup option # "--defaults-file". # # To run run the server from the command line, execute this in a # command line shell, e.g. # mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini" # # To install the server as a Windows service manually, execute this in a # command line shell, e.g. # mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini" # # And then execute this in a command line shell to start the server, e.g. # net start MySQLXY # # # Guildlines for editing this file # ---------------------------------------------------------------------- # # In this file, you can use all long options that the program supports. # If you want to know the options a program supports, start the program # with the "--help" option. # # More detailed information about the individual options can also be # found in the manual. # # # CLIENT SECTION # ---------------------------------------------------------------------- # # The following options will be read by MySQL client applications. # Note that only client applications shipped by MySQL are guaranteed # to read this section.

  • hibernate and ehcache replication

    - by cachingsol
    Hi, I am working on a cache replication solution between nodes Node A - master node = Hibernate + Database + Ehcache as secondary cache Node B - regional node= Ehcache as prmiary cache. no Hibernate Node B is used only as near-by cache for query. Now I am updating data (Say SudentInfo) in Node A, it gets persisted and cached correctly. On replication side (I am using JMS) it sends a message to Node B. But the problem is, the message it sends is of instance CacheEntry(deep Inside Element), there is no way to resurrect the original object (StudentInfo). What I got in node B is CacheEntry with some attributes of Students but not actually an Student Object. Please note that I don't need Hibernate session/persistence in Node B, node B is only for fast query, persistence is done through Node A. So has anybody tried any solution like this? Is there any way to convert CacheEntry to actual object? or Tell ehcache to replicate original object rather than CacheEntry. Thanks for the help

  • Client-side Replication for SQL Server?

    - by Mighty Z
    I'd like to have some degree of fault tolerance / redundancy with my SQL Server Express database. I know that if I upgrade to a pricier version of SQL Server, I can get "Replication" built in. But I'm wondering if anyone has experience in managing replication on the client side. As in, from my application: Every time I need to create, update or delete records from the database -- issue the statement to all n servers directly from the client side Every time I need to read, I can do so from one representative server (other schemes seem possible here, too). It seems like this logic could potentially be added directly to my Linq-To-SQL Data Context. Any thoughts?

  • Database Replication OOD Pattern

    - by MrOnigiri
    Greetings fellow overflowers, After reading on MSDN about correct strategies on how to perform database replication, and understanding their suggestion on Master-Subordinate Incremental Replication. It left me wondering, what OOD design pattern should I use on this... The main elements of this strategy are the Acquirer, the Manipulator and the Writer. The first fetches data from the database and passes on to the second which might perform simple transformations to the data, before handling it to the final element, the writer, that writes the desired data on the destination Database. I thought about using the Chain of Responsibility pattern, but the Acquirer, Manipulator and Writer don't share a common role among theme, so It makes no sense. Should these elements be written as separate classes, or methods inside my service? Of course I'll be creating a DB Helper class as well, but that doesn't constitutes a problem. Wondering what your opinions on this are! Thanks for your replies

  • Articles about replication schemes/algorithms?

    - by jkff
    I'm designing an hierarchical distributed system (every node has zero or more "master" nodes to which it propagates its current data). The data gets continuously updated and I'd like to guarantee that at least N nodes have almost-current data at any given time. I do not need complete consistency, only eventual consistency (t.i. for any time instant, the current snapshot of data should eventually appear on at least N nodes. It is tricky to define the term "current" here, but still). Nodes may fail and go back up at any moment, and there is no single "central" node. O overflowers! Point me to some good papers describing replication schemes. I've so far found one: Consistency Management in Optimistic Replication Algorithms

  • sql server 2005 replication article conflict

    - by Daniel
    Hi all, I have a sql server 2005 database that I want to setup replication for. The problem is that the database has two schemas both of which have a table with the same name in it. For some reason even though the tables are in different schemas the replication creation fails when done through management studio due to conflicting article names (i assume its trying to create the same name for both tables in the different schemas). Is there any workaround for doing this in the studio, I can probably write a script or program to do this but just for this one thign is a bit annoying and it probably wont be allowed to run in production. Perhaps there is a hot fix or something I'm not aware about? Cheers,

  • Extracting Data Daily from MySQL to a Local MySQL DB

    - by Sunny Juneja
    I'm doing some experiments locally that require some data from a production MySQL DB that I only have read access to. The schemas are nearly identical with the exception of the omission of one column. My goal is to write a script that I can run everyday that extracts the previous day's data and imports it into my local table. The part that I'm most confused about is how to download the data. I've seen names like mysqldump be tossed around but that seems a way to replicate the entire database. I would love to avoid using php seeing as I have no experience with it. I've been creating CSVs but I'm worried about having the data integrity (what if there is a comma in a field or a \n) as well as the size of the CSV (there are several hundred thousand rows per day).

    So how do I go from installing MySQL from the Software Center to inputing data into fields and bringing in a comma delimited file? I've only had brief experience with MSAccess and OOo Base a long time ago, so details are appreciated, I just want to get up and running. I have Ubuntu 10.10, 64 bit, if that affects much. If you can link me to a howto that does exactly what I'm looking for, that would work. Again, Thanks!

    I've got a pretty substantial XLS file a client provided 830 total tabs/sheets. I've designed a multi table database with PHPMyAdmin (MySQL obviously) to house the information that's in there, and have populated about 5 of those sheets by hand to ensure the data will fit into the designed database. Is there a piece of software or some sort of tool that will help me format this XLS document and map it to the right places in the database?

    Today when looking at a couple of projects on a ZFS 7320 Storage Appliance I noticed on one project that one of its replication actions had failed, as I hadn't checked the Recent Alerts log yet I was not aware of this. I decided to write a small script to check if there were others that had failed. Nothing fancy, just a loop through all projects, look at the project's replication child and compare the values of the last_sync and last_try properties and print the result if they're not equal. (There are probably more sensible ways of doing this, but at least it involves me getting the chance to put on my headphones and doing just a little bit of coding.) script // this script will locate failed project level replication // it will look at the sync times for 'last_sync' and 'last_try' // and compare these, if they deviate you should investigate. // NOTE! this code is offered 'as is' Run at your own risk, // it will probably work as intended, but in now way can I // (or Oracle) be held responsible if your server starts behaving // like a three year old kid in a candy store.. (not that mine do, // they are very well behaved boys...) run('configuration'); run('storage'); printf('Host: %s, pool: %s\n', get('owner'),get('pool')); run('cd /'); run('shares'); proj=list(); printf("total projects: %d\n",proj.length +'\n'); // just for project level replication for(i=0;i<proj.length;i++){ run('select '+proj[i]); run('replication'); //get all replication actions preps = list(); for(j=0;j<preps.length;j++){ run('select ' + preps[j]); last_sync = get('last_sync'); last_try = get('last_try'); // printf("target %s\n", get('target')); //why the flip does this not get the proper name? if(!( last_sync.valueOf() === last_try.valueOf())){ printf("sync has failed for %s %s\n", proj[i], get('target')); }else{ // printf("OK %s %s\n", proj[i], get('target')); } run('done'); //done with the replica action } run('done'); run('done'); } printf("finished\n"); For a more on how to run the script, or testing it please look at my previous post. Sample output: Host: elb1sn01, pool: exalogic total projects: 45 sync has failed for ACSExalogicSystem cb3a24fe-ad60-c90f-d15d-adaafd595639 finished

  • Next lowest value in MySQL Database [migrated]

    - by Justin Edwards
    SELECT * FROM `experience` WHERE `reqexp` <> '4793' ORDER BY 'lvl' DESC LIMIT 1 Here is what I want to do. I am making an online game for a client, and need to be able to use a mysql query with a random value, and find the level associated with that amount of experience. In this case, I need to find the next value lower than 4793 that already exists in the database so I can determine the players appropriate level. Any Ideas?

  • How to install MySQL 5.6?

    - by Ross Smith II
    I just installed Ubuntu 12.10 (amd64), and want to install a recent version of MySQL 5.6. If possible, I would like to install (not upgrade) it the "Debian Way' (i.e., using apt-get or dpkg). The only binaries I could find are here. Unfortunately, they are incomplete, as they only install files in /usr/share. If binaries aren't available, how could I install it from source, using the standard Debian method of installing from source. Thanks for any assistance.

  • Upgrade MySQL to 5.5 on Lucid, upgrade server to Precise or switch to Percona?

    - by xref
    Looking into upgrading mysql on our development server to which is running 10.04 so is stuck at MySQL 5.1, as it appears there is no apt-get support for upgrading to 5.5 except by certain 3rd party PPAs. So I'm looking for which route to take and what other people have done: a) Follow a couple year old guide to manually install MySQL 5.5 and then invest ongoing time into manually downloading and installing security updates every month or two? b) Upgrade 10.04 to 12.04, and from other peoples experience I work with spend several days working out the kinks of that large upgrade, then I'll have access to mysql 5.5 and easy apt-get installation of future security updates? c) Switch from MySQL to Percona Server 5.5 and get all the benefits of that version of mysql, plus easy apt-get updates with their PPA? d) Something else?

  • iptables change destination address base on result from mysql

    - by user1812225
    I need to change destination address of tcp/ip packets based on result of execution mysql query... SELECT `score` FROM `reputation` WHERE `ip` = packet.source_ip if (score < a) then packet.destination_ip = ... else packet.destination_ip = ... What ways of solving this problem do you see? Thanks. P.S. this is important that destination host knows REAL ip address where packet came from, not IP address of firewall.

  • Where to apply these akonadi settings for mysql-server?

    - by piedro
    I Am using an external mysql-server to work with akonadi. (using KDE4). Now I could solve all problems with it, but I still have to apply some settings to the "mysql-global.conf"-file of the server. That's what is suggested for example: # wait 365d before dropping the DB connection (default:8h) wait_timeout=31536000 So I tried to change this setting via the mysql console. But it's not reflected anywhere in the /etc/mysql/my.cnf file. (etc/akondai/mysql-global.conf seems to have no effect on the mysql-server either!) My question: Where to put these (or similar) settings to apply them in a way that akonadi won't drop the connection with an external server (globally I guess?)?

  • Cant connect to mysql using self signed SSL certificate

    - by carpii
    After creating a self-signed SSL certificate, I have configured my remote mysqld to use them (and ssl is enabled) I ssh into my remote server, and try connecting to its own mysqld using ssl (mysql server is 5.5.25).. ~> mysql -u <user> -p --ssl=1 --ssl-cert=client.cert --ssl-key=client.key --ssl-ca=ca.cert Enter password: ERROR 2026 (HY000): SSL connection error: error:00000001:lib(0):func(0):reason(1) Ok, I remember reading theres some problem with connecting to the same server via SSL. So I download the client keys down to my local box, and test from there... ~> mysql -h <server> -u <user> -p --ssl=1 --ssl-cert=client.cert --ssl-key=client.key --ssl-ca=ca.cert Enter password: ERROR 2026 (HY000): SSL connection error Its unclear what this "SSL connection error" error refers to, but if I omit the -ssl-ca, then I am able to connect using SSL.. ~> mysql -h <server> -u <user> -p --ssl=1 --ssl-cert=client.cert --ssl-key=client.key Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 37 Server version: 5.5.25 MySQL Community Server (GPL) However, I believe that this is only encrypting the connection, and not actually verifying the validity of the cert (meaning I would be potentially vulnerable to man-in-middle attack) The ssl certs are valid (albeit self signed), and do not have a passphrase on them So my question is, what am I doing wrong? How can I connect via SSL, using a self signed certificate? MySQL Server version is 5.5.25 and the server and clients are Centos 5 Thanks for any advice Edit: Note that in all cases, the command is being issued from the same directory where the ssl keys reside (hence no absolute path)

  • Connecting to MySQL Server from PHP Command Line (MAMP)

    - by Austin White
    First of all, I'm using Mac OSX 1.6, MAMP 1.9, PHP 5.3.4, and MySQL 5.1.44. I'm in the process of setting up a video encoding service for a site using Chris Boulton's PHP-Resque and Redis. Once the worker process is fired and the videos have been encoded, I need to save their locations to a mysql database. The php script is being run from the shell, so that is where the issue begins. I import the mysql settings and when it attempts to connect, I get the following errors: Warning: mysqli::mysqli(): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known in /Users/austingym/Documents/Dropbox/Website/htdocs/homefree/lib/MySQLi_Extended.class.php on line 24 Warning: mysqli::mysqli(): [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servn (trying to connect via tcp://MYSQL_SERVER:3306) in /Users/austingym/Documents/Dropbox/Website/htdocs/homefree/lib/MySQLi_Extended.class.php on line 24 Warning: mysqli::mysqli(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known in /Users/austingym/Documents/Dropbox/Website/htdocs/homefree/lib/MySQLi_Extended.class.php on line 24 Warning: mysqli::set_charset(): Couldn't fetch MySQLi_Extended in /Users/austingym/Documents/Dropbox/Website/htdocs/homefree/lib/MySQLi_Extended.class.php on line 32 I realize that the error is occurring because it's trying to connect to tcp://MYSQL_SERVER:3306, when MySQL is on port 8889. I've been reading about Mac OSX and MAMP errors regarding the mysql.sock and I've gone through multiple forums and tried various fixes, but none have worked. I've tried PATH=/Applications/MAMP/Library/bin/:/Applications/MAMP/bin/php5.3/bin/:/opt/local/bin:/opt/local/sbin:$PATH and sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /tmp/mysql.sock but neither have worked. I even ran a search on my machine for "3306" to find where it's being set, but because that's the normal default, I'm guessing it's not being set explicitly. Any clues on how to fix this rather challenging error?

  • Recover mysql database - mysqldump gives "table <tablename> doesn't exist (1146)"

    - by Matthew
    Backstory Ubuntu died (wouldn't boot) and I couldn't fix it. I booted a live cd to recover the important stuff and saved it to my NAS. One of the things I backed up was /var/lib/mysql. Reinstalled with Linux Mint because I was on Ubuntu 10.0.4 this was a good opportunity to try a new distro (and I don't like Unity). Now I want to recover my old mediawiki, so I shut down mysql daemon, cp -R /media/NAS/Backup/mysql/mediawiki@002d1_19_1 /var/lib/mysql/, set file ownership and permissions correctly, and start mysql back up. Problem Now I'm trying to export the database so I can restore the database, but when I execute the mysqldump I get an error: $ mysqldump -u mediawikiuser -p mediawiki-1_19_1 -c | gzip -9 > wiki.2012-11-15.sql.gz Enter password: mysqldump: Got error: 1146: Table 'mediawiki-1_19_1.archive' doesn't exist when using LOCK TABLES Things I've tried I tried using --skip-lock-tables but I get this: Error: Couldn't read status information for table archive () mysqldump: Couldn't execute 'show create table `archive`': Table 'mediawiki-1_19_1.archive' doesn't exist (1146) I tried logging in to mysql and I can list the tables that should be there, but trying to describe or select from them errors out the same way as the dump: mysql> show tables; +----------------------------+ | Tables_in_mediawiki-1_19_1 | +----------------------------+ | archive | | category | | categorylinks | ... | user_properties | | valid_tag | | watchlist | +----------------------------+ 49 rows in set (0.00 sec) mysql> describe archive; ERROR 1146 (42S02): Table 'mediawiki-1_19_1.archive' doesn't exist I believe mediawiki was installed using innodb and binary data. Am I screwed or is there a way to recover this?

  • The MySQL service is in the status "starting" on windows

    I have several months working to "MySQL-5-1-47" on windows 2003. When I restarted, the service "MySQL" stay in this state "starting". The only way to raise the service was running the program directly: C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld This is the MySQL error log 100906 16:07:29 [Note] Event Scheduler: Purging the queue. 0 events 100906 16:07:32 InnoDB: Starting shutdown... 100906 16:07:37 [Note] Plugin 'FEDERATED' is disabled. 100906 16:07:38 InnoDB: Shutdown completed; log sequence number 0 44233 100906 16:07:38 [Note] mysqld: Shutdown complete 100906 16:07:39 InnoDB: Started; log sequence number 0 44233 100906 16:17:21 [Note] Plugin 'FEDERATED' is disabled. 100906 16:17:22 InnoDB: Started; log sequence number 0 44233 100906 16:22:01 [Note] Plugin 'FEDERATED' is disabled. 100906 16:22:02 InnoDB: Started; log sequence number 0 44233 100906 16:22:02 [Note] Event Scheduler: Loaded 0 events 100906 16:22:02 [Note] C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld.exe: ready for connections.

  • MySQL unstable behavior with external stroge

    - by onurozcelik
    In our project we are using MySQL 5.0.90(InnoDB engine) server with an external storage. We store MySQL data files in an external storage. When the external storage down for a reason we have unstable behaviours. So we made some tests. In Windows Server 2008 We closed external storage physically. MySQL service stoped and we could not reach the server. Then we opened the storage unit and we could not start service until we reconfigured MySQL. We made storage unit offline from operating system. After 3-4 minutes and some insert trials(some insert trials succeded) MySQL service stoped and we could not reach the server. Then we made storage unit online and we could start the service(not automatically). In Windows Server 2003 We made storage unit offline. After 3-4 minutes and some insert trials(some insert trials succeded) MySQL service stoped and we could not reach the server. Then we made storage unit online we could not start the service until we reinstalled MySQL. Before reinstall we tried to reconfigure but it did not work. We closed external storage physically. MySQL service stoped and we could not reach the server. After that we opened the storage unit and we could start service(not automatically) We expect service to autostart after storage unit is online/open. But these tests show unstable behaviors. Is there any solutions to this.
