If you check out [url], you can see that its not running super fast. The load is nothing, iostat, vmstat, etc don't show anything out of the ordinary. Is there anything else I can do to see what might be causing it? Am I just in need of some good mysql optimization?
View 6 RepliesMy sites have been receiving a little more traffic these days (but not too much) and it seems my vps is slowing and at times vbulletin/wordpress page doesn't loads or loads a bit sluggishly (refreshing the page gets rids of not loading issue but not sluggishness).

My Cpanel VPS has around 384MB of dedicated ram and around 896Mb of burst Ram. At any given time, there is at least 150Mb of free dedicated RAM. So based on this, are these values correct or they need to be changed or do I need to look for something else which might be causing this problem?

I have a new DS with Plesk 12. I needed to change the default /var/www/vhosts location to a different physical drive, with more capacity.The larger disk is mounted as /disk1, so I created a folder here called vhosts, moved everything from the existing /var/www/vhosts directory, then I mounted /disk1/vhosts as /var/www/vhosts. See my fstab output below.
I then edited /etc/psa/psa.conf to update the VHOSTS location as per [URL] ...., and restarted Apache, MySQL and reconfigured domains.I thought all was OK, and that Plesk would just see /var/www/vhosts as normal, but I proceeded to migrate domains from another server to this box, and found that whilst some sites were working OK, many were not.
I was finding that existing config directives that used <Directory> were being ignored or seemed to disappear.All sites with .htaccess files stopped workingWe would get Apache / PHP errors saying that files could not be accessed as they were not in the allowed path for the domain. Plesk seems to be logging, reporting, and handling files as if they were in /disk1/vhosts, not the usual location. I have got sites working by adding /var/www/vhosts/ domain and /disk1/vhosts/domain to the PHP Settings page as allowed paths.
I have checked in the httpd.conf for each domain, and they all list the site document root as /disk1/vhosts/domain, not /var/www/vhosts/domain.It's as if Plesk is ignoring the change in /etc/psa/psa.conf.
All I want is for Plesk to think that /var/www/vhosts is the document root for all domains, and not do anything with /disk1/vhosts. I have many sites with hard coded links to included files in /var/www/vhosts/domain, and I dont want to have to rewrite them all to use /disk1/vhosts.
I have had to stick HTTP configuration directives on nearly every site, and add these entries to the allowed paths box, which obviously I should not have to do. Can any Plesk / Linux gurus tell me what I need to do to fix my problem, get sites working in /var/www/vhosts, and have Plesk allow .htaccess files to work without me having to add "AllowOverride All" to every domains??

I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?
I'm currently on a VPS 2.0 Pro package from WebFusion. Ubuntu.
I've been with them for years, first on shared, now VPS. I generally run Invision discussion forums on them, as well as a few static websites.
Ok for disk space, memory etc. but recently it has been sooooooo slow, lag is getting unacceptable. It is intermittently ok, then slow as treacle. My customers are starting to complain.
I've spoken to tech support, and all they say is it's fine, but will look into it and then contact data centre.
To be honest, over the last few years I've seen a decline in tech support and customer service, but wondering what to do now. I pay annually and my budget is about £400 pa.
Renewal is due about March, but thinking about leaving early. Just getting too much hassle.
I just wonder who to go with? Do the smaller companies offer the same performance? Do they all have the same connnections to the backbone?
Or maybe it's a weird apache thing?
I have a website that I recently moved to a dedicated server. Before hand I had the website hosted with 2 other hosting companies (not dedicated).
I decided to go to a dedicated server because the website ran extremely slow or even went down due to traffic.
With the dedicated server I am having the same problem with the same amount of visitors online. This usually occurs with aprox 250 members online.
I know nothing about servers and have no idea how to cure this problem or if possibly it could be a setting in the server. However this is killing my website because new people are unable to register because of site coming down from traffic.
One of my sites gets around 10k+ visitors a day which has caused my httpd to be really slow.
My MaxClients is set to 250.
What should I do to get it back to normal?
I am migrating my sites from a Xen based Centos 5.3 + cPanel/WHM instante to another Xen based cPanel/WHM solution with Centos 5.3 64-bit. I am having issues with easyApache now after it was successfully ran for the first time.
It does not time out however even the profile selection screen takes well over 10 minutes to get to once easyApache is initiated. Once the profile selection is made it is still slow moving to the customization screen.
The server is neither overloaded, nor out of memory. I have actually executed /scripts/checkperlscripts in hopes that it would identify something. I am planning to remove /home/cpeasyapache folder however I am not confident whether this is the right approach or not.
there is no one didnot hear about the Price increased @ LT
so i may need to know and ask evry body..
where did you moved ?
or
where are you think to be moved to?
i'll be more than happey if you help us and tell us with why did you moved to this one
Today, without any change on the server side my single running website on my server started running low. After checking the running processes I realised I have these 8 processes running with high cpu load something that didn't had before.

apache error log doesn't show any warnings, errors.
I'm currently getting DDoSed. I'm on a VPS and my host has asked me to get the troubled domain off the server asap.
Question is, should I move to a dedicated to avoid affecting other users? Or should I find some shared/VPS hosting which has ddos protection?
one of my servers currently died (it was a 1u System) Dual Xeon, 3GB RAM. I need the DATA off my SCSI harddrives.. i have a 2U system only, but when i try and put the SCSI harddrive into the Machine, windows crashes on the "Windows 2003 " starting screen. Windows, ugh, horrible. I need to get into windows to get my MSSQL database's backed up and then moved to a new server.
View 11 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?
Since I moved to vps emails are some how being blocked by hotmail.
I have a forum which needs email activation but those registering with hotmail do not receive emails
Now cpanel is having some issues. Certain places acknowledge the new IP, others don't. IE all of my nameservers are still set to the old IP's and I can't seem to change them because they are already asigned to the old ones, etc. What can I do to try to fix all of this? Is there an easy tool? Is there a file I can just change?
View 1 Replies View RelatedQuestion for people who have moved to InnoDB: I wonder if it is worthwhile?
I don't care about ACID compliance, my only interest is in the row level locking which I do not get with large MYISAM tables which do table locking and clog up everything. I have a huge database that needs frequent updates, like 50,000 per hour. I also don't care about InnoDB's large size of indexes and such, I have lots of hard disk to throw at it.
My fear is with the backup of InnoDB tables, and the fact that it is not as simple to "fire up" the tables when I restart the database. MySQL manual suggests something like a query to "Warm up" the tables.
Any thoughts would be great, and if possible, any help with what settings you use. FYI, I am on a 4GB RAM machine with dual Core2Duo procs. When I tried the following in my.cnf for the InnoDB stuff ---
Code:
#skip-innodb
innodb_buffer_pool_size=1G
# Set the log file size to about 25% of the buffer pool size
innodb_log_file_size=250M
innodb_log_buffer_size=8M
innodb_data_file_path=/idbdata1:200M:autoextend
innodb_additional_mem_pool_size=20M
innodb_log_group_home_dir = /iblogs
innodb_log_files_in_group = 2
innodb_flush_log_at_trx_commit=1
innodb_lock_wait_timeout=10
--- the MySQLD wouldn't start! Question about the stuff in red: what're those paths for?
Do I need to create those paths?
I been reading this forum for a while now and now i have a VPS for my blog. The reason i moved from shared to VPS was due to my old webhost told me i was usuing to many CPU power and it was causing the server to crash.
Now with the VPS same thing is still happening. My apache keeps hanging due to too many connections and only way to bring my site up is rebooting the VPS. i contacted the webhosting and they have me setup a cronjob to restar httpd every hour but that still doesnt do it.
This is killing me. I get around 1 million hits a month on my blog. I tried optimizing my apache and sql with the instructions i found here but it didnt help.
this is the plan i have:
Disk Space 30,000 MB (30 GB)
CPU Limit Equal Share
Guranteed Memory 256 MB
Burstable Memory 1024 MB
Monthly Bandwidth 2,000 GB
Control Panel cPanel / WHM
I recently moved my website from a shared hosting plan at Siteground to a VPS at WiredTree. All went well but I have this problem : When I try to access my website I can't. I get :
Forbidden
You don't have permission to access / on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
This happens only for my home computer. If I try to access the website from anywhere else (even via my mobile phone) it works like a charm.
I am thinking this might be a DNS cache problem. Anyone can help me better understand the problem and solve it?
I recently moved a site from one hosting company to another. I went to the registrar and pointed the DNS at the new nameservers, and set up a new ftp account to upload the site. The DNS seemed to resolve ok after a few hours, (in my browser I was seeing the new host's default home page) so I uploaded the site to the new host.
Today sometimes I see the new site and sometimes the old!
I'll be editing pages and uploading them by ftp, then suddenly I'll see a different directory structure on the remote server. Similarly I'll refresh my browser while looking at the new site and... Hey! I'm seeing the page on the old site!
I've cleared the browser cache on my machine btw.
My guess is that either a server somewhere in the path (at my local service provider?) is throwing out old cached versions of the page, perhaps when it is busy, or that not all the nameserver/dns records have updated.
I am trying to push my server to return Moved Permanently code and redirect these URLs to the main URL, but cant find the right code.
domain.com
w.domain.com
ww.domain.com
wwww.domain.com
to
www.domain.com

I finally got my site moved over to Cartika's server. They were a big help with several issues I had, even fixing things that didn't have anything to do with their server.
I had to get a new template since the other one was only available at .wordpress but I like the new one much better anyway. I still have to go through each page to make sure I didn't forget to change some link or something. I also had to edit the php to work how I have it so I may have missed something (I haven't even seen php since 2003).
I'm writing a post about my initial impressions of Cartika and why I eventually chose them. I'll post the info at WHT when I finish it.
I just moved my site to point to a new server (changed nameservers) and everything is working fine but a subdomain.
My subdomain links.example.com still points to old site when example.com points to the new site.....
Should I delete that subdomain at the old host?
Should I just be patient?
Should I change nameservers for subdomain at old host?
The subdomain is configured at the new host already.....
I just moved my site to dedicated server due to shared hosting capacity problem. Again I am facing Too many connection problem, when i contacted go daddt they replied as follow
Quote:
Thank you for contacting Server Support. There are a couple of things you might want to check. First is how you have your httpd service configured. Make sure you have sufficient MaxClients defined in /etc/httpd/conf/httpd.conf. Additionally you will want to refer to your /etc/my.cnf file to make sure you have it configured to allow as many max_connections and max_user_connections as are needed.
I am using Redhat Fedora with Plesk as control Panel. Any help how i can change this Max_user_connections?
I recently moved a site from a hosting company to a VPS. I updated the name servers with the domain name registrar and the transfer went smoothly.
However one thing does have me puzzled. As I understand it (and correct me if I am wrong) my new hosting company are now the authority for my zone and should have a zone file which points my domain name at one of their IP addresses? However my previous host has a webbased email panel - if I log in to it I can still send email (but not recieve). This has confused me as I would have thought that my new ISP would have a zone file with an MX record for my email? How is this possible?
this is my server and i host only one site as upload image but it is too slow and usully apache down
how i can optimize this server please
