MYSQL :: Mysqld Is Not Running Properly

Mysqld Is Not Running
cannot seem to run mysql commands, although queries seem to work well as I can make databases and view tables. Hope that makes sense.

I installed mySQL 5 on Windows XP and tried to stick with the default installation options and paths. I lauch mySQL from this: ""C:Program FilesMySQLMySQL Server 5.0inmysqld", enter a password (but not a username so I'm assuming that's root user), get a mysql> prompt. So far so good.

The following commands do not seem to work though:
mysqladmin version
mysqladmin variables

Typing these commands then clicking the return key brings up the -> prompt. I've checked the processes and "mysql.exe" and "mysqld-nt.exe" are running. From a c: prompt I tried to install mysqld and was told it is already running. What am I missing here? I'm sure it is something very simple...

Ultimately I need to bring in a table from a SQL dump from another system. I've tried using variations of: mysql -h host -u user -p dbname < dumpfile.sql

I'm combing through the docs, but still don't have a clue.

Mysqld Running 100 Pct Cpu Usage
I am testing mysql 4.1 on a Windows Server 2003 with a website running on Internet Information Services. I installed mysqld as a service.

As times goes by, mysqld begins to reach 100 pct cpu usage and doesn't goes below that, Windows usage is slow, folders opens slow, navigating locally turns to be slow, and sometimes it makes the server to freeze or restart.

When this begins to happen, I executed the command "Show processlist" and I got the following result. If somebody can point me where is my mistake or where is the problem or any solutions for this, I'm still in a learning process for mysql. Code:

Mysqld Will Not Stay Running
Sbj: mysqld will not stay running more than fraction of minute

    I removed all of mysql for a fresh beginning. I reinstalled from Suse Linux 8.0 distribution cdroms the packages mysql (which has the server parts) and mysql-client (the clients parts).  At that point ps -A did not show mysqld running.  In /etc/rc.d is visable the new mysql start-up script for running it by turning on the system.
    I ran '/usr/bin/mysql-install-db' after usage of the su (super user) command.  It did not indicate failures.  'ps -A' still showed no mysqld process.
    After su command, I ran '/usr/bin/safe_mysqld &' as suggested by manual in /usr/share/docs/packages/mysql.  The message stated 'Starting mysqld daemon with databases from /var/lib/mysql ... date / time ... mysql ended' _ . ps -A showed no entry for mysqld when I issued that command in another console window.  This continued to be so after shutting down, cycling power, starting up.
    Just as a check, I issued 'mysql -u root' command.  Msg came back,  'error 2002 unable to connect to local MySQL server through socket /var/lib/mysql/mysql.soc <111>' .
    How can this problem be solved?

Mysqld Process Running High CPU
My Mysql server is running at around 60% CPU even
when there's virtually no queries going through -
I turned on logging and have been watching the
queries and looked at mysqladmin processlist but there
is nothing unusual - this just started happening.
I tried using myisamchk which didn't find any
problems with my tables.

Using Keys Properly
I have a couple questions on how to properly create keys. Basically i know nothing about them, how they work, how it speeds things up, and most importantly, where to create them to help speed up my tables.

I do have multiple tables that are used and joined together, i just dont know where to make keys. I heard that if you do it improperly, it can slow down your database too?

UPDATE Will Not Add Properly
I have an online comic engine I'm working on, and I just noticed that, as opposed to adding one view (like it should) it will always add two. Can anyone help me out with this? I've already determined it's just this line of code, and that it's not being called twice.

$query = "UPDATE `".SQL_COMICS."` SET comic_views = (comic_views + 1) WHERE comic_id = '".$comic_id."' LIMIT 1";
mysql_query($query) or die(mysql_die_message());
echo($query);

Properly Querying A Relational Db.
I've recently been working with more relational dbs and I was just wondering...am I working with them properly?

The reason I ask is because I'm wondering if there are easier/more efficient/more "proper" ways to be working with a relational db.

So here is an example: two tables, a project table and an employee table. The project table stores employee id in emp_id and is linked to the employee table by a foreign key (a one to one relation).

SELECT P.project_id, E.first_name, E.last_name, P.name, P.code, P.start_date, P.end_date, P.imdb
FROM project AS P, employee AS E
WHERE E.emp_id = P.supervisor
The thing is eventually we'll start to have tables with 4-5 foreign keys and I'm wondering if this is still "proper". Honestly it may seem a stupid question to some of you experts :-p

Getting Utf8 To Work Properly
I have made a few tables in a database, and I'm trying to get my Japanese text to display properly. I have the collation set to utf8_general_ci, and I even added the mysql_query("SET NAMES 'UTF8'"); code into the php page. But even with all of that in, it still won't display properly. The characters show up as ã‚»ã‚*ãƒã‚¯ã«ã‚“ã˜ã‚ƒãŸã„ã‘ã¤ï¼ and other junk like that.
Now this was working before until I added a second mySQL connection into the page, which inputs the second table. I'm not sure if you can make 2 connections on the same page, but I did and it pretty much messed everything up. I took the second table away, and things were still messed up.
My question is how can I get the Japanese text to display properly? It does display properly on the phpMyAdmin page, but I get garbage on the actual page.

How To Install Mydsl Properly
is there a step by step guide for installing mydsl properly and creating a databse?

Search Does Not Match Properly
i had created a search function on a web application.

the problem is, i try enter some of info to it, certain text can be found but certain text can be match although they are in database.

this my query:

$keywordu = strupper($keyword);
$keywordl = strlower($keyword);

$sql = "SELECT E.* FROM employes AS E, dvi_problem AS DV WHERE AS.empId = DV.empId AND (E.emp_name LIKE '%".$keyWordl."%' OR DV.reference LIKE '".$keywordi."''%".$keywordl."%' OR E.emp_name = '%".$keywordu."%' OR DV.reference LIKE '%".$keywordu."%')"

$query = mysql_query($sql, $db) or die('Fail to search.');

i test with direct copy the data from database, some string i copy can search it but some other string i copy direct it can work wo...

i try show out the variable $sql value, it show with not error, the keywordu n keywordl aslo show out the value when i print out the $sql variable.

Designing Databases Properly
After what seems like far too much agonizing, I think I've decided to build my own php "shopping cart" and hack my own interface to paypal IPN, because all the other solutions I've come across are massively oversized and overdeveloped for my needs.

But I could use some help in setting up the structure. I'm not sure of the best way to handle "options" with my various products.

First of course I set up a basic database with product fields like:
sku, price, name, etc. etc.

The tricky part is that some products will have special options, some dropdowns and some text fields, and I know I won't be able to predict all these in advance, like:
item color, accessory color, font, initial, initials ...

In addition, some products will call for extra product photos and others won't ...

And then I will need some way of storing all these extra options for a given customer's order when it comes through.

Extended-insert Not Working Properly
I am having a problem with using the --extended-insert option when using mysqldump. As I understand it, this option creates multiple insert statements within the .sql file for tables that contain more than 1 row of data.

According to documentation I have found, this substantially speeds up the restoration process. The main database I am concerned with uses the InnoDB engine, however I also want to backup the mysql database as well (which, to my knowledge, uses the MyISAM engine).

However, when I execute the database dump using this option, there is only 1 insert statement, and all values are seperated by commas. When trying to restore my databases, this causes my system to eventually freeze up due to the inefficiency of inserting multiple rows this way. I am using Windows XP, 1.8 Ghz, 512 MB of RAM.

The command I am issuing is as follows:

mysqldump --opt --single-transaction --u root --all-databases > "C: estbackup.sql"

I have also issued the following command, with the same result:

mysqldump --extended-insert --single-transaction --u root --all-databases > "C: estbackup.sql"

Properly Re-starting Replication Process
I've just tried to re-start a replication process and the slave's
tables came up marked as crashed. I'm doing a repair on one of them but
there are a lot of databases/tables so I can't check them all (or is
there a table entry somewhere that flags crashed tables?) Here is the
sequence I used: Code:

Storing Large Integers Properly
I am storing book isbn numbers in a table. isbn numbers are 10 digit
numbers and many start with 0. The data type of the field I am storing
this info in is a bigint(16) unsigned.

It appears that isbns that start
with 0 are going in as 9 digit numbers, the 0 is being ignored or
stripped. I have experienced this before with integer data types
ignoring leading 0s. I'm wondering how to address this? Should I
change the field to a varchar or char data type?

Two Digit Numbers Not Formatting Properly
I have a table I am using to populate drop-down menus. It is for languages.
each language has a specific code that must be saved to the field in question.They work fine except for two codes: 00 and 01.
I can't change the codes to anything else. They have to be 00 and 01. THey are saving to the spreadsheet as 0 and 1 however.

Inserting Dates Properly Formatted
I have a dataset that has all it's date formatted as MM/DD/YYYY. I want to be able to insert this into a table that is using a field set as 'date'.
How would I go about properly formatting the MM/DD/YYYY to insert into the table?
Right now when I insert I end up with all the dates storing wrong. IE: 9/6/2005 stores as 2009-06-20.

Mysqlcheck: Clients Are Using Or Haven't Closed The Table Properly
I'm using the command mysqlcheck --all-databases --auto-repair --silent
and I see these warnings (listed below) on a daily occurrence. Is mysqlcheck
causing these warnings? I can't see how a table can close inappropriately.
How can I prevent this.

Hoping to here from MySQL users who have came across this. I'm using MySQL
4.1.11 on RHEL. Code:

Getting Text Retrieved From Mysql To Fit Tables Properly
I have been working on a really simple mysql/php set of pages.

Page 1: Input 3 peices of data (Title, Date and Text)

Page 2: Display all news that has been inputted

I have it working, except for one problem. My website is built with html, and tables. I want it so that when the text gets to the edge of the table, it drops down a line and starts again on the next line - so it doesn't carry on and on.

Theres no problem with title and date - they're just a few words, but the text part of the news is usually 5 or 6 lines long. This means that it wont all fit on one line without ruining the entire website display. Code:

How To ORDER BY DESC Properly. It Makes 150 Before 50 If ASC Order!?
I have this list:
50
150
200
250
300
350
400
450
500

If I order it by ASC order then mysql results this:
150
200
250
300
350
400
450
50
500

What the hell ?? How do I order it properly?

Mysqld-nt
What is mysqld-nt?

My.cnf And Mysqld
I just finished installing mysql on my box. but i don't have my.cnf file or mysqld anywhere. but i'm sure mysql is running already. Code:

Mysqld Max
I am trying to make mysqld max so i can create innodb tables but I am
getting the following error when i run mysqld

No Variable Match for: -0 'innodb_buffer_pool_size = 40M'
../mysqld version 3.23.56 for pc-linux on i686

I am unable to figure out what to do. This shows that it reads the my.cnf file
but how can I get rid off this error??. My computer have just 64MB ram. Do u
think that less ram is causing this error.

DBI With Mysqld
Can I use DBI to interface Perl with mysqld running locally rather than
with a 'true' MySQL server?

Mysqld Don't Log
In /etc/my.cnf I put an entry under [mysqld] section for mysqld.log as
following:

log = /var/log/mysqld.log

However, mysqld actually does not log anything. Can any one out here
help me to make it working.

Mysqld-nt
I am trying to eliminate the password that is associated with the 'root'.
When in start with mysqld-nt --skip-grant-tables, the cursor goes down to
the next line, but never gets to a new prompt.
When I do alt-cntl-del and look at the processes, it shows mysqld-nt is
running, it just sits there and flashes.

Mysqld
This could be a silly question, but I have a web-based MySQL/PHP application that contains sensative data. Now, I realize that MySQL is most secure (over network transfer) using SSL, but would there be a reasonable tradeoff to consider not using SSL if the only host that is allowed to connect to it is the localhost?

I.E> there would be no out/in network traffic, so wouldn't adding SSL only slow things down without gaining much (if anything at all)?

So, basically the only thing that can connect is PHP on the same server?

Mysqld-nt.exe
I run a phpbb2 forum on a winxp pro pc (up to date) with msyql 5.0.18, apache 2.2.0 and php 5.1.2. Every once in a while (maybe once a month or so), mysql unexpectedly and spontaneously terminates. This usually happens when no one is at the server (i.e. when the server is doing nothing other than running phpbb2, apache, msyql and php). The apache logs reveal nothing suspicious.
Anyone know why this might happen? And maybe more to the point, anyone have a suggestion about how I could rig my server to monitor whether mysql is running and automatically restart it if it's not (so that I don't run into the problem where my forum goes down because mysql terminates and I can't do anything about it till I get home to restart mysql)?

Mysqld-max
I have a mysql server with a couple hundred-thousand entires that constantly maxes out our server at peak times to the point where the database locks up. It uses up 99.9% cpu and over a gig of memory on our Dual Core 64 Athlon 2 Gig DDR machine.

Removing Mysqld-net.exe
Recently I removed MySQL 4.0.15 from my pc, but have noticed that a process called 'mysqld-nt.exe' is still running in the task manager. I have tried shutting down and uninstalling the service via the command line, but since the mysql directory no longer exists the system reports there is nothing to remove!

Should I re-install mysql 4.0.15 and try un-installing it again, or does anyone know a quicker way to fix this problem?

Mysqld Logs
I have a DATABASE server running MySQLD 3.23.58.Users vist and sign up
their interest in my website.Now the problem is arising that when a
user signs up first , they get emails of confirmation from my
server.In addition to these emails , the customer also gets some
annoyed e-mails from someone residing/depending totllay on @yahoo.com
email-address maintaining the anonymity.

I did try by sending only e-mails to some my own email address,
whether someone is sniffering through my traffic, but I got no e-mail
except the ones I had sent myself.

After this I added some other email addresses in my DB server but I
sent no email to them at all.This time all email addresses got those
*annoying* e-mails also.

Number Of Mysqld
i want to limit the number of mysqld daemons running on my linux system. despite my best efforts to search/find the configuration option for this i haven't been able to find a single bit of info on this topic, including searching the configuration options for the my.cnf file. right now my server is running twelve copies of mysqld, and i only need 3 at the most. i'm sure this is possible, i just don't know how. can anyone help me?

/var/log/mysqld.log Not Written To
for some reason, the mysql error log is not being written to. If I stop mysqld, rm the mysqld.log, start mysqld, the mysqld.log get's created. However, it doesn't contain anything. It should at least have 'started...' and a few other lines indicating that mysqld was started sucesfully, no?

Here is my my.cnf as it pertains to the logs:

--log-error=/var/log/mysqld.log
--log-slow-queries=/var/log/mysql.slow.log

/var/log/mysql.log is chown mysql.mysql and chmod -rw-r-

Has anyone else experienced this? Any suggestions?

Mysqld Got Signal 11
I run 2 servers in a master-slave configuration (both Solaris 5.8 [64 Bit]
and mysql4.0.14). Mysql (only on master) crashes exactly every 15 Minutes
with the following message:

-----schnipp---------------
mysqld got signal 11;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, something is definitely
wrong and this may fail. Code:

Mysqld Startup
I'm using ssh to administer a mysql server, version 3.23.49, which I
just installed.

The problem when starting mysqld: I type "mysqld" at the shell prompt
and hit return, then I get the message "mysqld: ready for
connections". But then it doesn't give me back the shell prompt. I can
type stuff on the screen, but it doesn't do anything. I've tried
Ctrl-C and Ctrl-Z, but that does nothing. Any ideas?

MySQLD Binary Log
We've been using MySQLD for a few years now quite happily. It's amazing
how well it performs. However, I have a minor issue, and I'm not sure how
to deal with it. I've scoured the manual, searched list archives, the
web, etc., and am coming up empty.

Somehow, the server is recording the Binary log in the data directory.
Each of these log files takes up a gigabyte. This would be all well and
good if we were using the server in as a master in a replication setup,
but we are not. It WAS formerly acting as a master in a replication
environment, but we've long since made it the only SQL server on our
network. We've removed (commented) all the lines in my.cnf that deal with
replication, and the log-bin is one of these lines. To clarify: the
log-bin line in the my.cnf file IS commented with a hash-mark (#). The
server has been restarted since this change, and "SHOW MASTER STATUS"
returns an empty set of data (only showing the field names.)

the SQL command RESET MASTER does nothing. It does not delete the
hostname-bin.### files.

the mysqld commandline parameters follow:
/usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql
--pid-file=/var/lib/mysql/inferno.pid --skip-locking

We're running version 3.23.41 for pc-linux-gnu on i686, running on SuSE
Linux 7.1, kernel 2.4.18 #2 SMP on a Dual-Processor Pentium II 450MHz
server

So, if any of you can shed some light as to why it would be saving the
binary log against our will, or as to how to stop it, it would be greatly
appreciated.

Handle Use By Mysqld.exe
When I run MySQL, I notice that mysqld.exe uses > 40,000 handles (according to Windows Task Manager).Is this normal? what all these handles are used for?

CAn't Connect Through Mysqld-nt
Here is a summary;
am working on win2k os, downloaded phptriad, mysql4.xx, php5.xxx and installed them all, now when i start apache i can connect to my server (i.e 127.0.0.1) now for mysql.

i noticed in task manager that there is mysql-opt is working, now from phptriad i run mysqlnt -d but i still can't connect to mysql using mysql FrontEnd, reading around, i tried mysqld-nt --console it says that there is another mysqld running on 3306, so changed the port for the mysqld section in my.cnf to 1234, but still can't connect.

Mysqld Stalls
I have two tables, a table of properties, and a table of locations (i.e., zipcodes). The following query takes so long I gave up waiting for it to complete:

SELECT * FROM properties LEFT JOIN locations USING (locationcode, locationtype) WHERE acres < 500 ORDER BY (price / acres) ASC, 'price' ASC LIMIT 100

I'm running debian linux, and:

mysql Ver 14.12 Distrib 5.0.13-rc, for pc-linux-gnu (i486) using readline 5.0

An EXAMINE of the above SELECT reveals:

id select_type table type possible_keys key key_len ref rows Extra
1 SIMPLE properties ALL NULL NULL NULL NULL 16424 Using where; Using temporary; Using filesort
1 SIMPLE locations ALL NULL NULL NULL NULL 31294

During the query, the mysqld process is using 99% of the cpu. Mysqld continues to use %99 of cpu even when client is killed. I finally gave up waiting and kill -15 mysqld. After a few seconds it gracefully died, and I restarted it.

The problem is 100% reproducible.

Does anyone have any clues? Is my SELECT above got a major flaw that makes the server go swap happy? I have 512mb memory, I'd think that'd be'nuff.

Mysqld Without LinuxThreads
does anyone know if it's possible to compile MySQL under Linux so that
mysqld doesn't rely upon LinuxThreads, but makes direct call to fork()
or clone() system calls instead?

I'm looking for a way to avoid the exploitation of pthreads under
Linux.

Can't Shutdown Mysqld
I installed mysql-4.1.7 on solaris 8. I can start it using
mysqld_safe. But when I tried to shutdown using 'mysqladmin -p
shutdown' and type in the root password, it gave:

mysqladmin -p shutdown
Enter password:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'oracle'@'localhost' (using password:
YES)'

I started mysqld_safe under Unix account "mysql", why it complains
about 'oracle'?

Mysqld Restarts Itself
One of my servers uptime is about 12 days... Last night I went to bed with everything running and ok. The next day around lunch time, I checked phpmyadmin and it seemed the database said "Uptime 10 hours" ?? And my memory (HEAP) rows were gone...

Does mysqld restart itself after days of uptime? If so, how can i stop it ?

Mysqld.sock (11)
I get the following error:
PHP Warning: mysql_connect() Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (11)

The server setup is: Ubuntu, PHP 5.0, MySQL 4.0.24, and lighttpd
This error seems to be appears when the load on the server increases. I've looked online and searched the devshed forums but still didn’t find a solution.

Normal Mysqld
I'm on a dedicated server that isn't live and I'm the only person that's on it.
I haven't done much on the box, yet when I check my processes with top, I see 11 mysqld processes lying there each taken up about 12 megs of memory.

Env: /etc/init.d/mysqld
when i start/stop my mysql this was the result..

[root@SM70192 /]# service mysqld start
env: /etc/init.d/mysqld: No such file or directory

Set Mysqld.log Size
I'm experiencing some problems due to big '/var/log/mysqld.log' size
(199 Mbytes), and I'd like to know if there's any method to set this
file's maximum size.

Mysqld.exe Using 33,638 Handles For 3 Databases
Running MySQL 5.0.37-community-nt on Server 2003 x64 SP2. We have 230 databases created, only 4 of which are in use according to MySQL Administrator. Currently mysqld.exe is using 33,638 handles the moment the service starts. In other deployments we generally only see about 4k handles for many more active databases. Can anyone shed some light as to why there are so many handles in use?

Mysqld Error On Startup
I should probably have left well alone, but I wanted to move
the installed location of mySQL. This all seemed to go OK, but when I moved
from something like:

/home/rob/mySQL/mysql-max-3.23.55-pc-linux-i686/bin

to /mysql

The when I try to startup the daemon I get an error

Can't find message file /usr/local/mysql/share/english/errmsg.sys

Now as far as I know I've never had this directory, or this problem. I can
start using ./bin/safe_mysqld & and everything seems to work OK. To further
complicate matters I also downloaded and installed 4.1 and the same happens
(it wan't an attempt to fix the problem, just something I needed to do)

When I try to find the settings file, (since I'd also like to change the
data directory location) which I thought was called my.cnf, then I can't
find one. Any idea what's happening
