Limiting MySQL Queries
Jun 30, 2007Is there any way to set max MySQL queries per hour to all MySQL users at once?
(lets say 20000 queries for each user?)
(cPanel/SuSE 10.0/MySQL 5.0.X).

Upto 150 MySQL Queries A Second
Apr 7, 2008I'm currently hosting all of my stuff with my own Wild West Reselling Account, i.e., InnoDomains.com.
Problem is I'm running multiple Wordpress Installations and a few websites that have some pretty intense MySQL work going on in the background, and I use about 250GB per month in bandwidth.
My Account gets the 503 downtime errors because according to Customer Service I cannot run more than 50 MySQL queries in one second. Well, that's not much of a challenge because a lengthy wordpress page runs about 90 queries and loads in 2-3 seconds. Time this by three including the other websites and a couple of shopping stores, and I'm easily doing more than 100-150 queries a second more than several times a day, thereby seeing that nasty, irritating error.
My other option is to split up all the websites over basic $ 3.95 per month accounts. I don't want to switch to a dedicated server yet because I'm not really making a whole lot of money (about $ 30 per month). Another thing I could do is move my MySQL testing to a local machine, and that may actually reduce the load on the damn server.
Are there any hosts out there that will allow me to do more than 100 MySQL queries per second? If so, are there any that are any good?
Mysql Slow Queries
Feb 25, 2007I added the following to my.cnf and restarted mysql
log_slow_queries=/var/log/mysql/mysql_slow-queries.log
I saw at leat 53 slow queries, however, there is no such file in that folder.
[MySQL] Too Many Connections: Locked Queries
Dec 17, 2008This has happened twice now. I have my wait_timeout variable set to 60 seconds, but occasionally my database gets overloaded with "locked" queries. Here's an example of my processlist:
Code:
| 14773848 | db_name | localhost | db_name | Query | 35483 | statistics | SELECT COUNT... |
| 14776290 | db_name | localhost | db_name | Query | 35144 | statistics | SELECT COUNT... |
| 14778877 | db_name | localhost | db_name | Query | 34841 | statistics | SELECT COUNT... |
| 14790744 | db_name | localhost | db_name | Query | 33056 | Locked | UPDATE... |
| 14791275 | db_name | localhost | db_name | Query | 32977 | Locked | SELECT... |
| 14791395 | db_name | localhost | db_name | Query | 32960 | Locked | SELECT... |
| 14791556 | db_name | localhost | db_name | Query | 32929 | Locked | SELECT... |
| 14791603 | db_name | localhost | db_name | Query | 32924 | Locked | SELECT... |
| 14791757 | db_name | localhost | db_name | Query | 32900 | Locked | SELECT... |
| 14792209 | db_name | localhost | db_name | Query | 32815 | Locked | SELECT... |
| 14792355 | db_name | localhost | db_name | Query | 32786 | Locked | SELECT... |
This continues on with locked queries all the way up to my limit of 450 connections, then the whole server goes down. Note the time spent processing these queries, 35483 seconds and counting! Surely the wait_timeout is supposed to prevent this from happening?!
Also, this appears to start with queries in the State "statistics". Then the State for the following queries becomes "locked". Does anyone know what these mean? Can I get them to timeout normally? Queries which never timeout are guaranteed to bring your server down eventually, surely this is not the desired behaviour.
No Clue: Automatic MySQL Queries
Apr 9, 2008I've been pondering something for a long time here, but never really knew the right question to ask, or how to word it... so I never even know what to search for. So I honestly have no idea what I'm asking or if this is even under the right topic. What I'm looking for is answers, links, tutorials, or just some words I can search for to help me do the following:
I have a MySQL database filled with accounts. People have to pay to get these accounts. All the accounts are set to expire on different days. I need to send an e-mail out to accounts, for example, to let them know they're expiring, say, a month before this will occur. Right now the only way I know to do this is to have MySQL queries on a PHP page that, every time the page is loaded, runs through all the accounts, checks their expirations, and sends emails to those that need it. I know there has to be a way to have this happen automatically without having to load a PHP page every day, for example.
MySQL Anyway To Log Queries Of Specific User
Jun 5, 2007I know about the general log but want to just log queries of a specific user. Our database does 400 queries/s on a slow day, so I think it would be a pain to grep though a huge log like that. And, im not sure if it would cause any preformance issues.

Jun 14, 2008What I did here was create /var/log/mysqld.slow.log for queries that are taking one second or longer. After around 36 hours, here is what I came up with. Since the file size of /var/log/mysqld.slow.log was 219KB, posting it in its entirety it not practical. Therefore, I used a program, the perl script known as mysql_slow_log_parser found on www.retards.org, to parse the mysqld.slow.log to make it easier to interpret and read. The result was that the original filesize of 219KB was converted to the smaller size of 14KB....
View 7 Replies View RelatedMySQL Replication Setup With 150 Queries/sec -> Major Lag
Jun 8, 2008I have fairly a large web site that has a forum and a torrent tracker.
Currently MySQL server is handling about 150 queries an avarage per second.
Here is the server spec:
Core2Duo 2.66Ghz
4Gb RAM
320GB SATA 7200RPM (Server provider does not have 1.5K RPM nor 1.0k RPM)
100Mbit Connection (servers on the same switch and the switch does not have 1Gbit port)
MySQL Version: 5.0.51a
I had Master-Master Replication setup with forum running on one and the tracker running on the other.
Although this has been working for about few days, we started seeing lags in the replication process.
After a week, there is a major lag and the changes made on one of the servers takes about 5 hours to appear on the another.
So, this doesn't work.
What would be the other ways of splitting MySQL queries concerning the same database?
While I was researching, I read about MySQL Cluster with database storage engine being NDB.
But, let's say that there is a power failure on both the nodes at the same time, then I would lose the whole database as the database is stored on the memory correct?
I would not like to take that chance either, but if this is faster then replication method then maybe I will concider.
I thought about editing the forum coding to make all queries that concerns the tracker to go in to, say server B (with forum's primary MySQL server being Server A), and make the tracker use server B as MySQL backend, but it seemed like a heavy work so that will be the last choice.
Limiting MySQL Memory Access
Sep 15, 2007I have a VPS with 256MB ram. i want to limit mysql memory access. suppose i want that mysql should not use more than 128MB ram.
is this possible? if yes how?
is this possible for all other services too?
VPS Incredibly Slow, Huge Numbers Of Slow MySQL Queries For Plesk/Watchdog
Nov 11, 2008I've got 25 domains on a Virtuozzo/Plesk8.6/CentOS5 VPS. Each domain has one up-to-date install of WordPress, most have very little traffic (average 200mb per month), maybe 2 domains get 5-7gb traffic per month.
I monitor port 80 connections and rarely see more than 10 at a time.
That should in my opinion be no problem at all for a VPS with 768mb guaranteed ram and 2.4ghz cpu. I've got 30gb hard drive spare too.
But.... about 8 or 10 times a day it grinds to a complete halt: server load at 500-1000%, sites timing out, plesk takes 3mins to load, often I can't even connect with SSH, and the plesk web server, apache
INSERT INTO module_watchdog_sys_stat (time, type, value, service_id) VALUES(FROM_UNIXTIME(1226404705), 'MAINMEM_USAGE', 17472, 11);
80 seconds sounds like a huge amount of time for a MySQL insert to me! Does anyone know if this is likely to be the cause of my trouble? Some problem with Plesk and the database? Or could it be something else?
DNS Queries From Our Server
May 10, 2007We host our DNS with DNSmadeeasy.com. We noticed that the number of DNS requests is too high. So we decided to contact their support and ask them for log file, so we can determine
what's going on.
Reply we got from them is the following:
We researched your queries and we found that many of them were coming from the SoftLayer resolving name servers. We phone their admins to report the abuse and they said that the queries were infact coming from your own server with them.
We will not charge for any overage on the queries this month so you can research what on your server is causing these queries. But we will provide you with logs of about 5% of our your traffic.
here is the example of the line from log file sent by them:
May 10 17:15:48 t145 named[29945]: client 66.228.118.72#52529: query: host-196.218.57.145.tedata.net.mydomain.com IN AAAA -E
May 10 17:15:48 t145 named[29945]: client 66.228.118.72#52529: query: afontenayssb-151-1-40-153.w83-114.abo.wanadoo.fr.mydomain.com IN AAAA -E
I changed the real domain name to "mydomain.com"
I checked the apache access log and found these hosts there in exact order as they are in log file sent by dnsmadeeasy.
What is strange is that why is my server making back these requests ? Also these requests are bad because these are not valid domain names:
e.g. should be "host-196.218.57.145.tedata.net" instead of "host-196.218.57.145.tedata.net.mydomain.com"
Seems that it includes ".mydomain.com" to the end of every request.
Is there a way to discover what is making those DNS queries?

Is it possible, through some script or otherwise, to send the traffic to certain/chosen domains to a completely different set of nameservers.? Preferably without having too much server load?
I already use a domain catchall, so no NS records are actually registered on the server.
Nameservers - Recursive Queries
Jul 14, 2008I am checking DNS Report for a domain and in nameservers records I am getting following:
Recursive Queries
I could use the nameservers listed below to performe recursive queries. It may be that I am wrong but the chances of that are low. You should not have nameservers that allow recursive queries as this will allow almost anyone to use your nameservers and can cause problems. Problem record(s) are:
xxx.xxx.xxx.xxx
I am using Windows 2003 Standard and Microsoft DNS Server. Any ideas what is this all about and how to fix it?
Apache :: How To 301 Redirect Queries

Simply redirecting search.php doesn't work, so I guess I need to use a wildcard?
Vbulletin... High Amount Of Queries
Dec 1, 2007I got a dedicated server which hosted 45 sites, one of those sites contains a vbulletin forum application since january 2007 , but from two weeks i found that there is a high amount of Queries from the this database which leads the server load to be always in RED and exceeds 200 or 300! and the memory is totally consumed!
i tried alot to solve this problem as :
- reinstall the vb.
- change the vb path to another ( considering it as attack)
- installing BFD , APF , ( considering it as attack )
- upgrading to apache 2.2.6 , PHP 5.2.5 , MySQL 5.0.24 ( considering it as a bug)

Input Wanted: Optimizing SQL - For Millions Of Queries
Jul 7, 2008I am running a SQL test server here that is piping HUGE amounts of data for a test project I am running.
Approximately 30 queries a second - constantly. That's over 2.5M queries a day -- so we are talking big (I think?)
I am currently running this test on a
AMD Phenom 9300, 4GB RAM - SATA 500GB HDD and I am running MySQL 5.0.51a i386 on CentOS
I have programmed a process control for our applications purpose - basically it controls the launching of our SQL intense applications, and stops launching when the Load is greater than 2.5
I have plans to optimize the number of queries (I will build in a cache to some of the applications - and run INSERT statements all together) however I am looking for SQL tweaks that will improve performance. Would running the 64bit version work better?
Wordpress Sql Queries Performance On A Shared Hosting Account

considering this is a shared hosting server with over 800+ more domains on it, is the performance better or worse when compared to other shared hosting providers ?

Apr 15, 2007I've recently hired a new server with the aim of offering FTP backups.
I have Plesk CP but I don't want to use that to create the accounts for these users - i want to use the Plesk license for webhosting customers.
My box is running CentOS with ProFTPd.
The problem i'm having, is locking down SSH access to the Backup customers - if i add an account using "useradd", it is enabled in ProFTPd as I want, and I have set ProFTPd to only allow access to their home dir. However, the users can still log in via SSH and have full access to the box. Ideally, I want to be able to remove these users from SSH access, or if that's not easily possible, not allow them to "cd" above their home dir.
I know it's possible to add their usernames to the SSHd config file under Deny, but is there a more elegant solution (bearing in mind i'm planning to have quite a few of these users)?

Limiting PHP Emails Per Hour
Jul 29, 2009On an cPanel + RHEL 5.3 box at WHM - Tweak Settings, I activated "The maximum each domain can send out per hour (0 is unlimited)" and set that value to "300".
But, it seems that this limit is only if the user is sending using webmail or an email client, right now a joomla website is sending much more than 300 mails per hour, but it's using php to send the mails.
My question, how can I limit emails per hour on each domain while sending from php?

Hardware Based IP Limiting
Aug 28, 2007I've been searching a while for a box that I can throw in front of my servers that will basically look at inbound connections and if there are more than X amount of connections from IP:XXX it will block it for X minutes.
I thought a standard load balancer would do it, but according to Barracuda, their load balancers don't. They do DDOS prevention, but that's based on packet inspection. What I'm looking for is something that will block legitimate traffic when there's just been too much in a short amount of time. Basically I've got people using autosurfing programs and refreshers on my site and I'm getting tired of analyzing log files to find them.
