Built from the Valley, MySQL 5.1.34 is available

Blogging and building live from MySQL Conf 09… If you want more details about what happens here (technical sessions, MySQL 5.4, InnoDB improvements, MySQL Cluster, Sun/Oracle fusion…) or want to enjoy a drink in the Valley, please let me know…

Back to the Dotdeb business : MySQL 5.1.34 has been published with its lot of bugfixes. It is now built and available on Dotdeb for your Lenny/Etch amd64/i386 Debian servers. No change in the packaging, just apt-get upgrade

After upgrading to 5.1.34 I ran into some trouble with stored procedures. The default config value for thread_stack is to low (128K) to do even empty procedures. Raising it to the default 196K should fix this.

See: http://forums.mysql.com/read.php?98,256564,256564#msg-256564

The message: Thread stack overrun: %ld bytes used of a %ld byte stack, and %ld bytes needed. Use ‘mysqld -O thread_stack=#’ to specify a bigger stack.

Cannot stop or start after installation on Lenny.
In logs I foudn syntax error 1064
…alter table user add column show_view_priv…

I upgraded from mysql 5.0 to mysql 5.1 on etch, and I get the same error during post-installation:

ERROR: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘ALTER T
ABLE user ADD column Show_view_priv enum(‘N’,’Y’) CHARACTER SET utf8 NOT ‘ at line 1

But mysql 5.1 appears to be running fine. I did manually ran mysql_upgrade to be on the safe side. I checked, and the user table already has this column in it. I am just trying to figure out a way to tell aptitude that the package is fully installed so it won’t keep trying. Perhaps there is something els I can do to make things better?

I think I found the issue, there is a syntax error in the mysql-server-5.1postinst file that I got when I did a apt-get install mysql-server-5.1, when I was running at the time mysql-5.0 (5.0.77). There is a missing comma:

” Show_view_priv=’Y’, Create_routine_priv=’Y’, Alter_routine_priv=’Y’ “\

You will notice the missing comma at the end. After I fixed that, it seemed to somehow tried to create the plugin table twice. I dropped the table and ran it again and it still gave me a ‘plugin’ table already exists. I just commented that part out. Then it had some sort of issue with the ‘# Automatically added by dh_installinit’ section where it would give a return code of 1. I then decided to run “update-rc.d mysql defaults 19 21 >/dev/null” manually, and then I put in a “exit 0” right before that section. This allowed it to appear to be fully installed to apt-get. And as far as I can tell, mysql is working perfectly fine.

I am not sure if there really is an issue, or just something I did wrong.

Thanks for providing these wonderful packages over the years.

Hi,

I just done with a clean install of LAMP, but when I try to stop or restart the MySQL server this is what I get:

# /etc/init.d/mysql stop
Stopping MySQL database server: mysqld failed!

# /etc/init.d/mysql restart
Stopping MySQL database server: mysqld failed!
Starting MySQL database server: mysqld already running.

Version: ‘5.1.34-0.dotdeb.1-log’ socket: ‘/var/run/mysqld/mysqld.sock’ port: 3306 (Debian)

What am I missing? thanks in advance

ok, but do I have to do this, and not able to restart the server normally?

# killall -9 mysqld_safe mysqld

After killing the services and tried to start it, here’s what I got:

#/etc/init.d/mysql start
Starting MySQL database server: mysqld.
Checking for corrupt, not cleanly closed and upgrade needing tables..
EC2-WebHost:~# ERROR 1045 (28000): Access denied for user ‘debian-sys-maint’@’localhost’ (using password: YES)

Thanks in advance

Do I still need to run mysqld_safe and not just the mysqld?

# ps aux |grep mysql

Thanks again

@Raleigh : safe_mysqld is the main binary in charge of launching the mysqld processes. For your error, you’ll have to reset the debian-sys-maint’s one and put it in /etc/mysql/debian.cnf

Sorry but how do I reset the debian-sys-maint?

here is the content of /etc/mysql/debian.cnf:

# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host = localhost
user = debian-sys-maint
password = *****************
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = debian-sys-maint
password = *****************
socket = /var/run/mysqld/mysqld.sock
basedir = /usr

thanks

@Raleigh : Just change the ********** with a good password (for – bad – example “yourpassword”) then execute this query :

SET PASSWORD FOR ‘debian-sys-maint’@’localhost’ = PASSWORD(‘yourpassword’);

should I create user first for ‘debian-sys-maint’@’localhost’? as there is only 1 user, root or should I edit the /etc/mysql/debian.cnf file and change the default password there?

@Raleigh : You shouldn’t have deleted this user, he’s needed for the Debian administrative tasks. To re-create it, execute this query :

GRANT ALL PRIVILEGES ON *.* TO ‘debian-sys-maint’@’localhost’ IDENTIFIED BY ‘yourpassword’ WITH GRANT OPTION;

I didn’t deleted it and also didn’t touched the file, I only learned those things here.

I’m somewhat a newbie with debian and mysql

Ok, I’m going to create a new user debian-sys-maint, is it ok to use the same password in the file debian.cnf or safe to change it and set to mysql?

thanks

ok done, added user debian-sys-maint on localhost and grant all options, I also changed the password in the file debian.cnf with my own password. did I got that right?

after that I stopped the mysql

# /etc/init.d/mysql stop
Stopping MySQL database server: mysqld.

then checked the status
# /etc/init.d/mysql status
MySQL is stopped..

then started it again
# /etc/init.d/mysql start
Starting MySQL database server: mysqld.
Checking for corrupt, not cleanly closed and upgrade needing tables..

does that one ok? not cleanly closed and upgrade needing tables? I have no new database yet other than mysql and information_schema.

thanks

Thank you so much! ^:)^

btw, do you have any documentation about your MySQL debian package?

thanks again

Hi Guillaume,
I just upgraded to mysql-server-5.1 (5.1.34-0.dotdeb.0-log) with Etch on one server and Innodb is not available (parameter have innodb = NO).

On another server that I updated some days ago with the same version (Etch and 5.1.34) it’s ok. Though they have exactly the same my.cnf.

On the net, they say that “have innodb = NO” means that innodb is not compiled with mysql. What can I do (if I can do something …) ?

@Jean-Michel : all my packages have InnoDB activated (disabling it is insane). Please check that the MySQL related packages are the same on the two servers and that they come from Dotdeb :

dpkg -l ‘*mysql*’ | grep ‘^ii’

Yes the packages are the same on both machines, that is :
> dpkg -l ‘*mysql*’ | grep ‘^ii’
ii libdbd-mysql-perl 3.0008-1 A Perl5 database interface to the MySQL data
ii libmysqlclient15off 5.0.81-0.dotdeb.0 MySQL database client library
ii libmysqlclient16 5.1.34-0.dotdeb.0 MySQL database client library
ii mysql-client-5.1 5.1.34-0.dotdeb.0 MySQL database client binaries
ii mysql-common 5.1.34-0.dotdeb.0 MySQL database common files (e.g. /etc/mysql
ii mysql-server-5.1 5.1.34-0.dotdeb.0 MySQL database server binaries
ii php5-mysql 5.2.9-0.dotdeb.1 MySQL module for php5

On the machine which have ‘have Innodb’ = YES, I have an additionnal package :
ii libmysqlclient15-dev 5.0.67-0.dotdeb.1 MySQL database development files

I don’t think if could have an incidence but I have to mention that on the machine with *NO Innodb*, I have got a problem at upgrade with the acpid package with the error :
Paramétrage de acpid (1.0.4-5etch1) …
Starting Advanced Configuration and Power Interface daemon: acpid: can’t open /p roc/acpi/event: No such file or directory
invoke-rc.d: initscript acpid, action “start” failed.

I found some web pages related to this issue but nothing worked for me. But since Mysql is working at least for MyISAM, I don’t think the problems are correlated, are they ?

I’m still stuck with my “have innodb NO” problem. Removing and reinstalling mysql-server-5.1 brought nothing new. 🙁

With the same config as yours :

And yes, I have

@Jean-Michel : Where does your mysql-server-5.1 package come from? Please show me your sources.list. It seems that it’s a package built “à la Dotdeb”, but not coming from one of the official mirror.

Thanks Guillaume, you saved me (with some exchanges of emails).

Finally adding some lines to my.cnf solved this issue :

innodb_data_file_path = ibdata1:1G:autoextend
innodb_autoextend_increment=128M
innodb_log_group_home_dir = /home/mysql

innodb_buffer_pool_size = 2G
innodb_additional_mem_pool_size = 20M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 500M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
# origin : innodb_lock_wait_timeout = 50 (changed by JMA on 2009-03-06)
innodb_lock_wait_timeout = 100

(take care : my server has 8GB of RAM – the above figures are not for a server with 1GB RAM)

Jean-Michel’s problem came from his need to change the InnoDB files’ default location. To do this, you have to set BOTH the innodb_data_home_dir and innodb_data_file_path variables.

About the memory settings, these apply only on a 64bits machine too. A 32bits server will never address more than 3GB of RAM (depending on your kernel configuration, even with HIGHMEM) by process. Then, running MySQL on Linux on a amd64 or equivalent machine is a good idea if you have more than 2GB of RAM. The performance boost is noticeable (>=40%).

hi Guillaume,

we have a problem with mysql crashes, is there a way to get support for that ?

we are willing to pay if someone solve our problem …

On Debian edit /etc/mysql/debian.cnf:
# Replaces automatically generated for Debian scripts
[client]
host = localhost
user = root
password =
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = root
password =
socket = /var/run/mysqld/mysqld.sock
basedir = /usr

@”name” : Feel free to submit decent bug reports and to give a real name/email address. Please note that replacing “debian-sys-maint” by root in /etc/mysql/debian.cnf (especially with an empty password) is a very bad idea. Don’t be surprised if something goes wrong 🙂

@Daniel Anliker : I’ll email you very soon. Waiting this, please gather some information about your system :
– kernel
– debian release
– sources.list
– installed packages and their versions
– suspicious log messages in /var/log/syslog
– a way to reproduce the crash (application, storage engine, connection type…)

Hi, i am getting this error on debian lenny

This is what i have don

btw in this case i have install mysql-cleint and mysql server after putting dotdeb in the /etc/apt/sourcefile.list

* Configuring MySQL

In order to run Postfix and Dovecot chrooted, we need to make some changes to the configuration of MySQL

We are going to store the MySQL socket file inside Dovecot chroot :

#*
mkdir -p /usr/lib/dovecot/var/run/mysqld
cd /usr/lib/dovecot/var/run
chown mysql:root mysqld
#*

We are now symlinking the directory back into /var/run, DSPAM will use mysql socket file and expect it to be located under /var/run/mysqld/mysqld.sock

#*
invoke-rc.d mysql stop
rm -fr /var/run/mysqld
cd /var/run/
ln -s /usr/lib/dovecot/var/run/mysqld/
#*

You should change /etc/mysql/my.cnf and fix the paths :

#*
nano /etc/mysql/my.cnf
#*

[client]
port = 3306
socket = /usr/lib/dovecot/var/run/mysqld/mysqld.sock

[mysqld_safe]
socket = /usr/lib/dovecot/var/run/mysqld/mysqld.sock
nice = 0

[mysqld]
user = mysql
pid-file = /usr/lib/dovecot/var/run/mysqld/mysqld.pid
socket = /usr/lib/dovecot/var/run/mysqld/mysqld.sock

And finally also edit /etc/mysql/debian.cnf and fix the paths :

#*
nano /etc/mysql/debian.cnf
#*

[client]
host = localhost
user = debian-sys-maint
password = xxx
socket = /usr/lib/dovecot/var/run/mysqld/mysqld.sock
[mysql_upgrade]
user = debian-sys-maint
password = xxx
socket = /usr/lib/dovecot/var/run/mysqld/mysqld.sock
basedir = /usr

Restart MySQL :

#*
invoke-rc.d mysql restart
#*

If i install mysql first and change the sourcefie.list whit dotdeb and make de change as above. i get the same error but when i then mark #skip-bdb in the /etc/mysql/my.cnf which is default unmarkt i get is working again

Hi, I’ve installed the dotdeb packages, on xen vm Lenny-amd64 with 4 cpus, 8G Ram, for a lamp server(apache2, php5, mysql and ezpublish). All seems to be ok, until connexions starts. I’ve tested with ab and siege, the innodb thread crash and start automatic recovery. The debian1.err look like this:

090612 9:00:46 [Note] /usr/sbin/mysqld: ready for connections.

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.

key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=9
max_threads=75
threads_connected=9
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 641148 K
bytes of memory
Hope that’s ok; if not, decrease some variables in the equation.

This issue will be hard to fix, there’s no useful information in the backtrace and your config looks ok.
Are you using something special, like Google Perftools?
Anyway, a 5.1.35 release is on its way. Maybe it will fix this issue.

Hello,

My name is Doru. Yes, I have activated Google Perftools.
Well, i have to go back to lenny’s default mysql version now, but this one use all memory (8Go) and sometimes crashes the server. The dotdeb version correct the memory leaks (with the same config uses only 4G of 8) but when the number of connexions increases I have the bug.

Thanks for your answer

Hi,
Indeed, without Google Perftools, it’s working, but I can see the difference. Busy Ram is now ~6G when it was ~4G with the Perftools.
Thank you,
Doru

Hi Guillaume,
I’ve updated with this new google-perftools, but now mysqld don’t start (i’ve inserted the LD_PRELOAD line in /etc/init.d/mysql). The logged error is:

Hi, 5.1.34-0.dotdeb.1 just crashed on my amd64 server. http://dev.mysql.com/doc/refman/5.1/en/news-5-1-35.html shows it fixes a number of crashes. When can we expect a 5.1.35 dotdeb package? Thanks!

Hello,

After having upgraded Mysql, service began and crash… Sometimes, Mysql just does not live more than few seconds.

I went to 5.1.35 provided by Mysql (binary package), deleted everything, and recreate everything. I don’t have any crash yet. We’ll see wether they come backup or not.

I don’t use libgoogle…

For information, this is a big mysql server

@Sebastian Harnau : I don’t know why the official Debian maintainer does not update the mysql-dfsg-5.1 packages (my packages are just backports from experimental to stable) : http://packages.qa.debian.org/m/mysql-dfsg-5.1.html
I’ll backport a newer release as soon as it’s available on Debian experimental

@David Yan : No problem. If you have a “faster” repository than Debian experimental with clean Debian packages, let me know.

@Guillaume Plessis : Thanks for information, now it is clear, why it takes some time to provide these packages. And of course: Thanks for your work!!!

Hi,

after apt-get installation i get a error in phpMyAdmin: “Your PHP MySQL library version 5.0.51a differs from your MySQL server version 5.1.34. This may cause unpredictable behavior.”.

php5-mysql and libapache2-mod-php5 are allready “up to date”.

What should i do?

Tanks. 🙂

@Qwertz : as said in many comments on this site, that’s just a warning and there’s no incompatibility between 5.0 libraries and a 5.1 server in the PHPMyAdmin case. It should be fixed in PHP 5.3 with the inclusion of the MySQL native driver.

Try to comment this warning in PHPMyAdmin (main.php).
