if I could get some input on this. Currently I'm running an Opteron 246, 2GB RAM with 2TB bandwidth/mo. I run a single site which is currently 99% HTML, along with an invision forum which is fairly popular. I get about 300-400k pageviews per day.
Right now the server is able to handle this stuff without much of a problem, and the average CPU load is between .5 and 3 (after a TON of tweaking!) - the only exception is when the forum db is being backed up/optimized, which isn't a huge problem since it happens during the off hours.
The problem is that I'm running out of bandwidth quickly, and need to come up with some kind of solution soon. My current provider offers bandwidth at $1/GB, which to me seems crazy compared to other providers, so that's not really an option.
I was thinking about switching to a more affordable provider and upgrading hardware, but I'm not sure what the best approach would be. I'm in the process of moving my HTML content over to a PHP-powered CMS, so I need to make sure whatever I do can handle that... What might be a decent setup for a site like mine which consumes a lot of bandwidth and will probably need more CPU power in the near future for PHP/MySQL stuff?
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
today i got a message from a client asking about hosting his video himself, catch is, he has a shitload of viewers, im looking at servers in the range of quad core (maybe dual quad), 8gig, 4 hdd raid10, gige uplink, however the kicker, depending on how out of whack my estimates are, 100 to 400mbit SUSTAINED upstream (spiking all the way to max'n that 'little' gige pipe)
Has anyone got suggestions on who i should even consider for this? I'm a bit dumbfounded myself as i'v never even thought about a server on this much sustained bandwidth before today.
Like if you try to make your own server, it would cost a few thousand right? Or bought one from IBM or something. If you rent a server, it could cost you like double that I notice or even more in a period of a year.
I was looking at the prices of Xeon 5420 and they are like only 400 or something. Motherboard, ram, hdd's shouldn't amount to too much right?
And companies are charging like 50 bucks a month for a 2 gigs of ram.
Or am I actually looking at this wrong and actually am looking at desktop components? So is bandwidth the cost for these prices? In the long run aren't people being ripped off?
For the past few days, one of the server is causing a bandwidth utilization surge for the entire rack on almost daily basis. It happen for a few minutes and it went off then it will be the same thing again the next day. When the surge is happening, most of the servers on the same segment will be inaccessible for the few minutes.
The bandwidth utilization graph for my rack is recording an abnormal surge from (6mbps --> 90mbps) for the few minutes. My MRTG is showing 2 of the Plesk servers giving the problem but the NOC guys said it the Cpanel that causing the problem.
I tried logging in to both servers but could not find what's the cause for this.
I have a site that uses extreme amounts of bandwidth, I checked some of the popular companies like serverbeach and softlayer. Right now I'm leaning more towards serverbeach because they are cheaper, Are they a good company to go with? Let me know if you have any other recommendations.
Whenever I run the "top" command, I see that some of the user "mysql" records always have very high CPU usage, anywhere from 20-80% on average (I've seen 100%). There are multiple records that show this, which means that the CPU is always above 100%. My cacti monitoring account also shows messed up CPU statistics.
I am not too knowledgeable with servers, but I believe that this is a problem. How much CPU usage is a mysqld command supposed to use on average? Here is a copy of the top part of a sample top command:

I told my system manager about the cpu problem, and he said that he installed the cpulimit function on my server. I'm not sure if this is a good solution.
MySQL the last few days seems to be constantly the most demanding process in top, which it never was before. As far as I can tell, nothing has substantially changed with regards to traffic to MySQL driven sites on the server. Is there anything that might be wrong with the databases, etc., that might throw MySQL into a tizzy?
So the site got featured on [url]and now the server is drowning...
The Coppermine Gallery usually hovers around 30~50 users daily and now, 1800, and im at a lost as how I should configure mysql to take on such a load. right now it takes about 10 secs or more to load a page and sometimes it would time out. Because it si coppermine, all pages are dynamic and can't be cached -_-"
Here's the my.cnf right now after i played around with the numbers

I have a fairly high end server in which I have installed SIM. SIM is restarting Apache up to 10 times a day, presumably due to high load causing un-availability.
On restart, Apache / MYSQL is stable until the load / mem usage begins to climb then it is restarted again. Here are my 'load' stats for today:
Load for today High (2:18am): 4.63 Low (3:30am): 1.20 Mean: 1.84 Latest: 1.61
Mem usage for today High (1:36am): 9,192.9 MB Low (1:48am): 7,995.7 MB Mean: 8,683.1 MB Latest: 8,781.7 MB
I have seen it using 20GB RAM before.
I have tried to follow various optimisation guides but these seem tailored to less powerful servers.
The web application I run on this server is almost entirely MYSQL based, with thousands of DB calls a day. Across the entire system I probably get 200,000 bot hits per day or even more. At peak times search engine bots are literally hammering the server.
Anyone know a good script that I can run with cron or something? Mysql seems to be the #1 problem with a lot of my web sites, a restart usually fixes it right away for me, but I can't keep restarting my servers everyday manually.
My video sharing site has high traffic, alexa rate:3,000
My site has 2 servers to split the load. 2 servers share a mysql server. Using rrdns to load the balance.
Server A running mysql 5.0,lighttpd Server B running lighttpd. Server B connect to A's mysql database.
During peak time. B can not connect to A's mysql server. It says server not responding. But A still running fine. When I check mysql log file. /usr/libexec/mysqld: Forcing close of thread .....
And when run top, the load average is 20.
The spec of Server A Intel(R) Xeon(TM) CPU 3.06GHz dual core. 2G Ram.
Here is the my.cnf
Quote:
[mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock # Default to using old password format for compatibility with mysql 3.x # clients (those using the mysqlclient10 compatibility package). old_passwords=1 max_connections = 1000 wait_timeout=60 connect_timeout=10 interactive_timeout=120 join_buffer_size=1M query_cache_size=128M query_cache_limit=2M max_allowed_packet=16M table_cache=1024 sort_buffer_size=2M read_buffer_size=2M
My question, do I need another maching C to run lighttpd, and just keep mysql on A. Or I can do some mysql optimization on A.
Also, if my site keeps going, can I have 1 mysql server and 5 http servers?

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.

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

I've a remote download site that uses tons of BW (about 900GB daily), and it uses sql connection quite alot - I've set it to max connection for my current server.
For now, I've the intention of separating main site with download server. where The main site will contains the sql DB. But my concern is, I want to buy a cheap VPS for the main site, but no idea if I need high BW and ram.
I host a podcast that's rapidly gaining popularity. At the moment, we push about 100gb/day of transfer for the episodes, but could easily double that in the next few months. I need a host that does at least 2tb a month with the ability to later upgrade to more. My operating budget is about 110$/month, but could go a little higher if needed.
Most of our activity is composed of sending files, so usage is pretty low. I'd probably only need a few gb to store the actual content (30mb mp3 files). It's also important that Adult material is allowed (the content of the audio podcast is explicit).
I'm aware of FDC and AT&T, but would like any other recommendations you guys could give.
I'm looking to get several dedicated servers, I don't require alot of processing speed or storage. And I'm not really picky about uptime, if the system is down for a few hours in a month its not a problem. What I need is alot of bandwidth. It needs to be quick and unlimited! What provider is going to give me the best deal?
The server is a media server, used to host heavy media files such as videos, flash and so forth. (there is no website on the server, just media files)
Everything works fine, all the media loads without a problem. Downloads are fast.
However, I have big trouble uploading stuffs. The FTP is either extremely slow or disconnects me.
I talked to my host, and they say the server is hitting 100Mbps bandwidth limit, and I should upgrade to 200Mbps. However, all my videos and media load fine, there are no problems except for the FTP.
Are there any solutions to this? I don't want to spend money on another 100Mbps just for FTP, especially when everything else is working without a glitch.
I have a client who has came to me for advice on his web site. I own a dedicated server and manage it using PLESK. I do pretty well managing it but I'm definitely not an expert on hosting by any means. So I need your help.
He is starting a new web site and he is going to do radio advertising on a lot of stations and expects to get a lot of hits. The web site seems to be pretty small with only a few pages of text and minimal pictures, so I don't think it will use that much just by the site being so small.
But anyway, I want him and me to feel comfortable that the site is not going to go down no matter how many hits he gets. How do I guesstimate this?
What are some good hosting companies that offer high bandwidth and protect you from overage charges -- or at least charge little for overages. I'm looking to spend less than $80/month. Also, do you have any idea: How many users will 10GB bandwidth cover if it's only a 5 page site with one picture on each page and 5 paragraphs of text just to get an idea.
I know someone is using the wget -r command on my server to recursively grab all files in a directory, I know their IP but I do not want to ban it completely, instead I was wondering is there a way to kill a connection if the bandwidth used by that connection gets too high?
I'm at leaseweb atm - according to their graphs, I am doing around 17mbps 95th and paying $33/m USD for a C2D+1GB+160G HD. Overages are rather expensive though.
I have a dedicated server currently hosted over by Aplus.NET
I have a 3000 GB Monthly Transfer limit and we have been going over this limit for the past few months. This has resulted in a large sum of overage fees.
I am looking to go to another hosting company that is just as good as Aplus.NET, if not better... with a better traffic rate. A friend told me about Choopa.com and I wanted to know how good of a company they were. What are some other top reliable hosting companies with premium servers and that specialize in unmetered bandwidth?
I'm picking up a client who is a video production company and hosts a lot of their work for their clients on the web. They have two sites right now for two different branches of what they do, but they are beginning to scale up a bit and want to switch from a local ISP hosting package to something more commercial. I like the idea of a VPS, but their current budget is rather low. Because of that, I am a bit attracted to hosting packages from site5 and dreamhost (both of which I've heard good and bad things about).
Ideally, I would be looking for a VPS along the lines of:
50-75GB disk space 256-512MB RAM 750GB-1TB Bandwidth Linux OS with Shell Access cPanel or Plesk Control panel
It'd be nice to keep their budget around $50/mo, but I know that might be asking a lot. They have two websites currently for their production needs. What would be the advantages of a VPS over multiple hosting accounts at Site5 ($7.50/mo) or Dreamhost ($6/mo)?
I'm looking at a project that would need to be located in Panama for server co-location.
It will be very bandwidth intensive, requiring 100 megabits to start and moving up from there. Going with a slightly more "value" oriented provider provided there's a backup (even lower bandwidth) available would be an option, as this application would tolerate limited periods of reduced bandwidth.
Can anybody point me in the direction of some data centers that might be worth looking at? Are there any bandwidth providers down there with a real value focus?
Right now, the best I've seen is $99/megabit from [url] I'm expecting bandwidth to cost more down in Panama, but I'd really like to push this number lower.
I know you get what you pay for with hosting, but with the ridiculous overselling going on I am finding it hard to work out how much bandwidth I can genuinely expect to get with about 500MB space and 99%+ (preferably more like 99.5%) uptime for $5/month.
I will be using all this bandwidth for hosting legal mp3s (sanctioned for promotional use by labels and artists), and would prefer the host to be based in the US or UK.
I'm new to linux and handling my dedicated server. I wanted to know how to setup a bandwidth cap/throttle for the users from my site. I wanted to limit the speeds to 300-400kb/s per user/IP. I've looked around but I haven't found anything really that solves my problem just scripts that protect CPU.
creating a setup that will host a site which is expected to receive 50-60K visitors in the first few hours after its launch. The site is membership based and the backend (member system) runs on PHP5-MySQL5.
Here is what I have thought of until now.
Site's sales page (which also happens to be the first page that visitors hit) hosted with Amazon S3 service. All public media files are off loaded to amazon S3 service to keep the number of requests on the hosted setup to minimum.
At the front we can have a high performance firewall like Cisco ASA 5520 followed by two dedicated load balancers in Active/Active state.
Behind the load balancers we have 3 front end servers acting as web-servers. These have SAS disks, 4GB RAM, RAID 1 setup, Dual Xeon Quad core processors each.
Behind the front end servers - we have a dedicated load balancer for the database cluster.
The database cluster consists of 3 Storage/API nodes and one of the front end servers acts as the management node. Each storage node has 8GB RAM, Dual Xeon Quad core processors, 4x RAID 10, SAS setup.
The private network is on a GigaLan.
Do you see any possible/obvious flaw in this design or anything that should be added/subtracted from the setup?
