I have 2000 domains set to
NS1.anydomain.com NS2 etc
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.
I have just upgraded my website, and set 301 redirects for all old pages.
But on the old website I used a search engine, and in Google Webmaster there are loads of 404 pages with search queries. They look like this: [URL] ....
Simply redirecting search.php doesn't work, so I guess I need to use a wildcard?
We 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?
how can i run queries in dnstuff.com
for examlpe we can run following query for DNS Lookup MX record

I 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:

I am using Windows 2003 Standard and Microsoft DNS Server. Any ideas what is this all about and how to fix it?
I'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?
Is 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).
I 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.
This 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.
I'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.
I 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)
this is the sample of queries.

I 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.
View 0 Replies View RelatedI 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?
What 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 RelatedI 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.
im running a few blogs on a shared hosting account (steadfast) and i noticed the 18 sql queries being generated by a fresh install of wordpress 2.7 are taking 0.246 seconds to execute.
<!-- 18 queries. 0.246 seconds. -->
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 ?

For those who run their own DNS servers I am interested in what DNS software your running on BSD or Linux platforms and on average how many DNS queries per second it serves on what hardware specification?
View 3 Replies View RelatedI'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?

View 1 Replies View RelatedI have multiple domains on my web server. One of my domains does not display its website when using example.com in the location bar.
Eg. example.com redirects to site2.com but www.example.com displays properly.
I tried adding to the htaccess file:
Quote:
Options +FollowSymlinks

It doesn't work. The redirect does not occur.
A benchmark for my website sais this:
Search engines may think serviciionline.net and www. serviciionline.net are two different sites.
You should set up a permanent redirect (technically called a "301 redirect") between these sites. Once you do that, you will get full search engine credit for your work on these sites. For example, serviciionline.net seems to have 3,058 inbound links whereas www. serviciionline.net has 32 inbound links. By correctly configuring a permanent 301 redirect, the search rankings might improve as all inbound links are correctly counted for the website.
How can I do that redirection? I have cPanel Pro in my hosting, and as far as I can see, with or without www, I land in the same place
