I am using /usr/bin/mysqlcheck --all-databases --check --auto-repair to check all MySQL DBs every day via cron. But sometimes when the DB crash and is being repaired the tmpdir = in /etc/my.cnf is getting full 100%. Is it any smart way to use some other tmp folder when repairing the DB tables like that?
View 6 Repliesim planning on designing a webservice, it will have a lot of data, spread in many tables.
The problem is that there will be tables created constantly (around 5 each day..)
All tables/data will be accessed equally, so I dont know how to set up the system, to create multiple databases, and balance the number of tables equally on each database, or create less databases and have a lot of tables on each one.
Which one has more efficiency?
This is the error that i get when i run test_setup.php:
Not all tables are ok!
Sorry, but there are error(s) found in the following table(s): 'records' 'domains'.
Please fix these errors and run the script again.
---
whereas rest of the tables (users, users_seq and zones)have been created.
Did i forget some step where these tables were to be created?
How can i create these tables now?
This is something i was wondering about and never found any answers.
Based on your experience, what are the most common reasons mysql tables crash?
I apoligize in advance if this is the wrong place to post this thread.
I am trying to create a CNAME entry in my DNS tables and have no clue where to begin.
I have did a search but didnt find anything that gives reference on how to do it just how to fix errors.
Can anyone point me in the right direction to learning how to accomplish this task.
I have a database which is growing to have about 100 tables. These tables will grow in size and sometime I will need to use RAID 5, I am told by my server provider.
My questions are:-
1. if these other servers are mirrors, should I have the database stored on each server?
2. when one server gets too busy, does the RAID query a lesser-used server so as not to bog down the first one?
3. Or, do I need to have different content in each db on each server so a query gets what it needs form each?
how exactly it helps?
mysqlcheck -o -u...
Like what it does to "optimize" them? Does it really help?
I am considering on implementing a new firewall in our colo which would have about 10 servers behind it which generates on averages 2.314 megabits/sec for everything.
I am looking at the new Watchguard x750e running version 10 of Fireware which seem like a good fit without breaking the bank but I have also thought of simply implementing a Poweredge server running CentOS and running an IPtables config to provide firewall services.
Anybody have any Feedback on the Watchguard unit or use a Watchguard product in their setup and can comment?
I have a vbulletin (3.7.2) board with many mods installed (nearly 70) without a problem.
However, upon installing one new mod I got a database error stating:
MySQL Error : Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (latin1_general_ci,IMPLICIT) for operation '='
How do I change ALL tables in one shot (or sql query via phpmyadmin) from the two different collations to utf8?
Also, is utf8 suggested or better than latin1?
In phpMyAdmin I see this:
Created_tmp_disk_tables 2,118 The number of temporary tables on disk created automatically by the server while executing statements. If Created_tmp_disk_tables is big, you may want to increase the tmp_table_size value to cause temporary tables to be memory-based instead of disk-based.
Created_tmp_files 0 How many temporary files mysqld has created.
Created_tmp_tables 5,637 The number of in-memory temporary tables created automatically by the server while executing statements.
I have tried upping tmp_table_size but it's no use. My my.cnf file:

# To configure this host as a replication slave, you can choose between

#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required

Is there a way to automatically check and repair mysql databases and tables, that can be scheduled as cron job?
we have mysql 5 setup and this morning at around 10:07 tables started disappearing as they were being accessed by different clients.
Databases that had 40 tables now had 30, etc. Only the tables that were attempted to be accessed were gone. This is the first time something like this has happened.
The following output was given:
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=8388600
read_buffer_size=131072
max_used_connections=208
max_connections=500
threads_connected=156
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 1096188 K

Hope that's ok; if not, decrease some variables in the equation.

Window server 2012 r2: I installed wordpress on a domain using plesk. Seemed to work correctly. But when I went to the site www.example.com/wp-admin, the native or default wordpress install started up. I could find no way to bypass this, so I just re-entered all the same settings.
The result was that I ended up with 2 sets of database tables, one set named with my chosen prefix wp_blahblah_ and one set prefixed with wp_blahblah_wp_.
Not good, so I deleted the later set. Wordpress seems to be working, despite one error on the tables I can't reproduce.
On my VPS I would like to set the /tmp folder to 777 and point to it with session.save_path.

But when i do this, php.ini in my custom account doesnt work any more... How can i custom php for one account and it not effect to main setting to prevent local attack?
