Are there some simple things that we can do or perhaps request our server management to do to optimize our server? Not sure where to start or what to ask so would like to learn some more before speaking with the server management company. Often times, you need to know the right questions to ask.
View 3 RepliesI am having problems with apache going down at least once a day. In Plesk there is a watchdog that monitors the service and then restarts it, but tries 5 times and fails, so apache will still be down and monitoring released. I really don't know what is causing this problem, maybe I could get some help? (Server specs at bottom of post, hope this is all you need)

Are there any services where an ADMIN can monitor DB usage on system and make some recommendations or even find SQL that is poorly written ...
I have a DUAL harpertown, 10GB RAM, and RAID
I have a typical, gallery, busy VB forum, and video script...
THe site traffic has not increased much but my Memory keeps getting chewed up... i already did some tuning that VBULLLETIN suggested... but the memory still goes... i need a tool or someone to just monitor the server for a day and grab as much diagnostic info as possible..
I suspect that its a single query giving problems cuz i have some custom coded pages...
I don't want to split the DB and HTTP request on diff servers cuz the traffic that i get shouldn't warrant it... for now...
A friend of mine has a VPS server from godaddy, the site he is hosting on this VPS is quite slow and times out a lot.
What would be the best option? Move out of godaddy? Upgrade the plan? or hire someone to optimize the server (apache/mysql).
If you would recommend the third option, it would be great if you can let me know about companies that provide this service.
The my sql seems to take much load in my VPs, configuration file is as follows

i have a Pentium D 820, 2GB Ram at LT where i am hosting a few proxies. Using Centos and Directadmin.
It's realy fast and i am happy with it. The only problem i am facing is that load is jumping up to 60 sometimes but just for a few seconds. Especially when a lot of people are using the proxy and it slows down a bit. That affects only the proxified pages and not a few personal html sites i also host there.
At the moment i am seeing in top that the CPU usage varies from 0,2 to 8, 12, 21 etc but just for a second or two
here is the top output

is there any way to tweak or optimize the server so than it can cope better when a lot of people are using the proxy.
it's getting to the point where I need to optimize MySQL to better handle a busy server.
These days it seems MySQL is using 30% - 60% CPU almost constantly. But, the good news is that I've got 4 gigs of ram on this box and their seems to be an access of 600mb free constantly throughout the day.
Is it possible to tweak MySQL to a little more RAM dependent and take some of the load off the CPU? It seems MySQL wont go over 300mb of ram at any given time.. I'm already working on optimizing the SQL Querys on the web page itself.

I have a 512mb cPanel VPS and would like to try and save a bit more ram, I have made the below changes to the httpd.conf and have also turned spamd, entropychat, melange, mailman, the only webstats I have is AWStats
Code:
MinSpareServers 2
MaxSpareServers 5
StartServers 3
Can anyone recommend any other changes to save some more ram ?
For anyone wanting to know, the VPS is being used to serve my websites

Which company do you recommend for VPS and MySQL optimizing?
I remember seeing a website/forum where you couldn't post your server stats and httpd.conf settings and experts would give advice on settings you should use.
Does anyone know the url to this site, or site similar to it
I optimized a mysql table of 2 million records and about 500MB.. it took about 15 minutes.. However, on the same DB now i have another huge table of 88 million records, it size is 2.2 GB and it has about 30 MB to optimize... my questions..
1.- How can I speed up the optimization process so it can take the less possible time? any tweaks to my.cnf?
2.- Should I repair it using phpmyadmin or just from the shell?
3.- Should I stop http traffic during this optimization?

We'd like to use this tool from Google on our Plesk server: [URL]
is it useful getting these tools going on server, and are they worth it?
I have four servers with a quad xeon, 4gb ram, and 2x300GB SAS 15K RAID0 harddrives, pushing a total of 1.6gbits. It serves a lot of zip files with an average flesize of 180mb. My question is, how can I optimize lighttpd 1.4.19 to push its max with very low IO-wait. I've looked up some stuff and only found options that deal with lighttpd 1.5 and use Linux-AIO for the backend network. Currently I use writev with 16 workers and an read/write idle timeout of 10s. Logging is off, too.
View 14 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....

Also what are the pros and cons of going with Virtual?
to move from shared windows hosting to Dedicated windows hosting. This will be our first dedicated server and experience with dealing it too.
Someone suggested me Rackspace. But they were charging premium rates 440 USD for entry level windows server.
I am currently using a shared hosting but due to increasing traffic and server load my existing host is not able to provide reliable services and I am planning to upgrade my hosting service.
While I was searching for Dedicated Servers, I learnt about Virtual Dedicated Servers but I am not very sure about their reliability? Are Virtual Dedicated Servers useful? My website current serves over 2500-3000 visitors a day resulting in 30,000 pageviews and I am expecting the traffic to grow by atleast 2 folds in the next few months as I start some PPC campaigns and Email Marketing for my website. Can a Virtual Dedicated Server cater such needs assuming my website to be more of less dynamic website written in php?
I have Plesk 11.5 (service provider mode) on a Windows 2008 server IIS7.Most of my sites are developed in .asp and therefore i use a custom 500-100.asp error page that check s the IP of the visitor then displays either a friendly error, or if its my IP a full error of what has happened (it also emails me the error). This allows me to debug pages easily whilst developing and to keep an eye on anyone trying SQL Injection hacks on my sites (as the error and email also have session variables and IP address).I dont have root access to the server as it is a Webfusion dedicated server.I have following the Plesk documentation -
1) Switch on custom errors for the subscription
2) Look in virtual directories and navigate to error documents
3) Find the error in question (500:100) and change it to point at either a file or URL
FILE - I had the data centre add in the 500-100.asp error page in to the virtual template so that my page is available in the list of virtual files - this didn't work but that maybe because its not a static page??
URL - when i add the path it says its incorrect, if i add a fully qualified address, it accepts it but it doesn't work.give me a specific example of the URL that can be entered relative to the root as the format in the documentation isn't accepted. The last step is to restart IIS which is also an issue as i cant seem to do this from the Plesk panel..It is as if it isn't catching the 500:100 error, and only catching the general 500 error??
What is the difference between a virtual private server and a dedicated server?
View 8 Replies View RelatedI am going to be buying a dedicated server from kimsufi Most likely the 2XL Package.
My streamers will be using my server aswell, On weekends we will be running 3-4 streams at a time, weekdays 1-2 at a time.
Spreading all the streams out, at anyone time we will have 300 viewers.
I need to know your advice on this before i go spending money.
How do i convert my dedi into a flash media server, i need red5 or something, thats all i know so far. My streamers wil be streaming to server with FME, And i also want it coded so that my streams can only be embedded on my site.
Basically i dont have a clue where to start, how long would it take me to set up etc....
In addition, what kind of server do i need, windows / linux / traffic / burstable / standard etc..
I'm expected to have around 1000-1500 users at a time after my ad compaign for my site.
currently, my setup is as follows:
VPS in UK
guaranteed memory: 256 burstable : 512
disk: 20GB
traffic: 200GB per month
price : 15 dollars a month
I would like to upgrade to :
guaranteed memory: 1GB
which is better ? to go with VPS ? or dedicated server ? which provider do u recommend ? how much am I expected to pay for my required setup ? what about CPU ?
Is it possible to upgrade a kernel on a dedicated server? I have a dedicated at Server.lu.
I opened a ticket with them, it was open for about a month with no reply.
How can I tell if GRUB or LILO is on the server somewhere?
I'd like to know, how do you backup a cPanel dedicated server to a remote FTP server? WHM's backup only allows you to backup the client's accounts, but not the cPanel settings, or the stuff in /etc?
View 5 Replies View RelatedI'm a a JAVA software developer and it happens that I need to configure a dedicated server running Win 2003.
It's already up and running with static IP address, however hosting offers a "Static IP Address", which doesn't really make sense, cause I already have one?
Other thing is domain name. Current domain name is registered with a different company and we don't really want to transfer it from that company. Can I get away with importing a domain name and changing MX records in the domain control panel?
Last thing is an email server. What do I need to set up an Email Server? I have a domain name with few POP3 email addresses. I thought about using hMail server for windows. What else do I need to do, pay for?
i want to know what is the difference between dedicated server and shared server. I was relaly confused in these services. Couls any one please let me know in detail about these servers?. I will be choosing one of these service.
