High-End Linux Hosts
Aug 27, 2008
My company's done shared hosting with our web site thus far. (I've gathered that the best of the best in shared hosting include Steadfast, DowntownHost, HostGator, Lunar Pages, and WebzPro. Any to add to the list, feel free!)
We're now thinking about moving to higher end hosting, i.e. a dedicated or managed server. So my questions are:
- Who are the biggest names and best quality Linux hosts in this category? That is, if those I mentioned above are "bargain" hosts, who are the "high end" hosts?
- What is the difference between a "virtual private server," a dedicated server, and a managed server? Ideally we'd like to still have a hosting package where security is taken care of and there's a lot of customer support to fix problems, but with our own dedicated resources.

Im a webdesigner so when looking for hosting i try to find one that is simple to manage, hardware powerful, lots of ready to install scripts and a beautiful webmail like Atmail or Zimbra.
So im looking for a powerful / quality high end "shared" hosting package.
Until now i have looked at:
- Mediatemple
(as @mail, exelent support but slow in Europe)
- Mosso
(is always good to be powered by rackspace but i think that the cloud hosting concept is still unsstable. Any experience?
- SimpleHelix (realy fast magento demo store, lots of scripts, @Mail and seems to have a fast network to europe)
So any advices on premium shared hosting?
An in Europe, any company similar to mediatemple or simplehelix?
Budjet: up to 100 $

What Linux web hosts out there know their stuff when it comes to securing and optimizing Linux based servers? As someone in another thread brought up, if a host doesn't know how to secure and run a server/server software, it doesn't matter what wonderful things they have installed.

I installed a new certificate, made it default, assigned it to the shared ip address and made the plesk panel use it.
The problem is we have 200 virtual hosts using the old certificate. Is there a way to reconfigure all those domains easily.

After changing my web hosting (same system : VPS, same version of linux : CentOS 6 , but passage from Plesk 11 to 12), i am now unable to connect remotely via TCP-IP to my mysql databases (with third-party tools like Mysql Workbench, Toad...) ! I never met this problem before.
The only way to connect is to use a "Standard TCP-IP over SSH" connection method ... but i don't want (i did'nt need this method before) !
Though, remote connections are allowed from any host in the settings.

I was in the market for a new dedicated server after a couple of years with my previous provider. The previous provider did nothing wrong but they were no longer competitive when it came to CPU and memory.
I moved first to geekrack. And I left them after a week and a half as they never were able to get my rDNS records setup.
I found Universal Hosts on this forum and gave them a shot. I had asked for an operating system that they didn't offer normally (Debian 64 bit) and they said that they could do it. However, when my server was setup it was 32 bit Debian instead. They apologized and had Debian 64 bit setup less than 24 hours later.
When I asked them to get rDNS records setup it took a few hours but they were setup correctly and they worked.
Universal Hosts is also a BurstNet reseller but compared to my other attempt at using a BurstNet reseller they are fantastic. While the initial config was incorrect they worked quickly to fix it and were very professional about it.
So after two weeks - so far so good. Keep up the good work UniHosts!

I am running Apache2.2, PHP5.I have been running with virtual hosts on a Windows 7 environment fine for a couple of years successfully, but have just had to move to a Windows 8 environment.It looks like Apache and PHP have installed and are working fine, but my Virtual hosts are now not being recognised. From what I can tell, it is the Windows 8 hosts file that is having a problem, as it looks as though it is now just setup to Block websites.
If I make the host file just have the one line127.0.0.1 localhost entry, then the very first Virtual Host from my apache config file will come up, but the rest are not found.If I put the usual 127.0.0.1 mywebsite.name aliasname is appears as though my website works momentarily and then is blocked..

This is a RHEL3 box. It has a couple hundred sites, most of which are pretty quiet most of the time, lately I can't get the load below 3 most of the time. I've tried all the usual TOP PS and the rest, but I'm not seeing my problem. I've attached a text file with extended outputs. but here's what I'm seeing now from TOP and VMSTAT. I'm not sure what else I could be looking at.
I've been watching, and it seems to be Apache most of the time at the top of TOP, and I'm logging slow-queries for myslq, but there aren't many there.
top

at 6 in the morning sa-learn / spamtrain starts to learn from junk mails.This causes high load on the system und takes about 2-3 hours.Is there any way to change the time to some hours earlier to avoid high load in office hours?
nice -n 19 ionice -c2 -n7 /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1
... to solve the issue, that it didn't seem to have any effect to your CPU/IO usage. Please try as well the full path, if you experience issues, as for example:
/usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7 /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1. Please make sure, that "nice" and "ionice" are located at the given paths and don't just copy&paste the suggestion with the whole path - usage ( you could use "locate nice" / "locate ionice" to verify the paths ).
You asked as well for a different execution time, to avoid high usage during office hours. I would recommend to try several spamtrain - cronjobs, which you might setup with
For Plesk 11 you would use:
nice -n 19 ionice -c2 -n7 /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f execute-spamtrain >/dev/null 2>&1
/usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7 /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f execute-spamtrain >/dev/null 2>&1
For Plesk 12 you would use:
nice -n 19 ionice -c2 -n7 /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f ExecuteSpamtrain >/dev/null 2>&1 /usr/bin/nice -n 19 /usr/bin/ionice -c2 -n7 /usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f ExecuteSpamtrain >/dev/null 2>&1
or use the direct command with: nice -n 19 ionice -c2 -n7 /usr/local/psa/admin/sbin/spamtrain >/dev/null 2>&1/usr/bin/ nice -n 19 /usr/bin/ionice -c2 -n7 /usr/local/psa/admin/sbin/spamtrain >/dev/null 2>&1
If you still would like to exclude one of the daily DailyMaintenance - cronjobs from your "50plesk-daily" script, you have to modify the line /usr/local/ psa/ bin/ sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php >/dev/null 2>&1
to all different parts like:
/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f Plesk-COMMAND-name1
/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f Plesk-COMMAND-name2
/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -f Plesk-COMMAND-name3
where you have to leave out the commands, which should not be executed daily. ( Please see the current Plesk-commands for the DailyMaintenance - script with "/usr/local/psa/bin/sw-engine-pleskrun /usr/local/psa/admin/plib/DailyMaintainance/script.php -l" and be aware that Plesk 11 and Plesk 12 have different commands! )
From time to time, it is wise to clean up the spamassassin - database ( as you already found out with the linked forum-thread), but I would recommend a 6-month-cronjob and not a monthly one. that spamtraining with spamassassin can be very time investing and you should try out addons, filters and rules to find the most efficient configuration for each, unique server - unfortunately there is no "best-for-all" solution.

We just ordered a new Dell server and trying to decide which flavor of Linux to use. The server is going to be used exclusively for a MySQL 5 database.
The MySQL database is very large about 9 gigs, (GIS data), and will be hit quite hard.
I was looking at CentOS and Fedora.
Here is the server specs:
2 Intel Quad Core Xeon 5410 2.33GHZ
8 Gigs Ram
2 146GB 15000RPM SAS Drives In Raid 1

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE
Parallels Plesk Panel 11.5.30 MU #44 CentOS 6.5 (Final) 64bit
2 of our our servers are suddenly experiencing high Wait I/O Times, and high Load Averages during the backup process. During this period the Plesk grinds to a halt, sometimes crashing out completely (although SSh is still possible. We have been in talks with our server suppliers (assuming this would be node related) however they have done a lot of testing etc. and categorically state the node is fine , with no other users affecting it.
STEPS TO REPRODUCE : We backup the server using the scheduled backup service and Wait I/O immediately goes up.
ACTUAL RESULT: Plesk downtime / Website downtime
EXPECTED RESULT: No downtime, successful back up
Some other info :
All other processes (MYSQL, apache, Nginx etc) are all running between 1 - 10%
Partition "/usr" utilization 4.2% used (1.81 GB of 43.3 GB) (?)
Partition "/var" utilization 50.6% used (61.8 GB of 122 GB) (?)
We are struggling to identify what has changed on the server that would cause this sudden change.

I have been trying to identify why mi server has high load cpu, suddenly CPU load suddenly jumps, from 1 to 40 and until 110
If I restart mysqld and apache, the cpu gets back to normal, until this happen again
My server is
GenuineIntel, Intel(R)Core(TM) i5-2400 CPU @ 3.10GHz
VersionParallels Plesk Panel v11.0.9_build110120608.16 os_CentOS 6
CentOS 6.4 (Final)
CentOS 6 x64 Processor: Intel Core i5 - 3.10 GH
I already installed FAIL2BAN and DDOS DEFLATE without lock. I have CloudFlare Enabled.
When there is a high CPU load, I have checked netstats, and I don't identify many ips connected, so I think it could be an internet script (or virus).
I will paste the result of
ps fax
command, in a moment of high cpu load

Recently I stumbled along a host on here with a good rep and that uses direct admin.
Because they were very nice on the live support I signed up to see what direct admin was like.
Its very diferent from cpanel. Some parts seem to be harder to use like the phpmyadmin requires the username and password to the database you created not the control panel username and password like cpanel. Although I guess that could be a good security feature just in case some one gets into the control panel they can not get into the phpmyadmin, then again if they are smart and were able to get into the control panel they could get into ftp and look what the username and password is on the config file for the script you are using.
The bandwidth meter seems to be better in direct admin although I think its acting up for me as its putting yesterdays bandwidth on todays. I was told by the host that it updates every 2 hours and at first it did but now its gone to every day. Oh and unlike cpanel this bandwidth meter includes bandwith used by the control panel.
Niether one from what I can tell counts sftp though at least for the hosts I have right now.

I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)

Our server is running; Plesk 11.0.9 and CentOS 5.7 it has a Q8200 CPU @ 2.33GHz and 2GB of RAM. Now there are just two websites on the server plus a couple of redirects/forwarding domains, although lots of domains are still on the server but turned off in Plesk. Both websites are OSCommerce sites and I just need to keep these sites going until the end of the year when we will switch to our new Joomla based website.
We have seen an increasing number of server crashes and after various checks of the logs, fitting a new BIOS battery, check of the hardware by EasySpace who host the server, installation of ClamAV, LMD and RKHunter (which did find some Trojans and Suspect software), I have traced it down to some external Http activity that is taking all of my CPU time and RAM. Here is a screen capture of the Htop listing and when I killed these processes the CPU and RAM went back to normal. The problem is that I usually have to restart the HTTPD service and sometimes things get so bad that the server crashes and I have to request a power cycle.

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.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
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.

I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.
I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.
Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed.
I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.
At this moment for example:
top - 09:00:36 up 15:43, 3 users, load average: 3.57, 4.60, 5.32
Tasks: 144 total, 2 running, 142 sleeping, 0 stopped, 0 zombie

I have a few questions about hosts.allow
1) There are 2 IPs in this file. I did not put them there. This is a dedicated machine. The IPs go to a Canadian hosting company. I am not in Canada and those are not my IPs.
2) Does my provider have the right to add IPs to this file without my consent?
3) I have already commented them out, of course, but I am concerned.

As some of you may know I have about 4 different webhosts.
the problem is thats to many and I want to maybe cut it down to 2 but not sure which 2 and thats my delema or jam.
Downtownhost is one of the 4 hosts and I have been with them for over 2 years now and its great and support it top notch. So would hate to leave them.
Everity is another one and they are great as well and very honest, which still impresses me today and I have not yet been with them a year but it will be this December. They were able to run my biggest site with out any issues and that was nice then again so was downtownhost able to well to a point until the space the site was using got to big for downtownhost which is why I got everity in the first place.
Hostsimplex is a new one I got to see what directadmin is like and wow direct admin is awesome and almost I want to move all my site to this host. They are also very nice/ friendly and support is also honest and gee a few times while opening up the live support for a question or a problem figiruing some thign out in direct admin I have gotten into long friendly convos with them. Kind of feel bad about that though as I would hate to take the support staff away from other customers. I do like also how they have free remote back up, which is nice but I still will make my own back ups locally just in case. Any way this host is still new for me so I am not sure how good or bad they are but so far its good.
The forth one is liquid webs as as of right now my main and largest site it on it. This hosting is not one I own but a friend/client. I am not even paying for it which is nice. How ever I have little to no support as I have to rely on my friend and he is not always on when I have an issue. Do to that this might be the first one I drop.
Although it it rare that I have issues and I do not have to worry about the cpu ussage, bandwitdth, diskspace because he said I could use what ever i want. He also said the server has a 500gb hard drive and not even 10% is being used.
Any way thats the issue I am having so which do you think I should drop or should I just keep them all as I do have an active site on each one.

if there's a list out there of the "trendy" web hosts; where it's cool to be hosted, etc.
For example:
Joyent
A Small Orange
Maybe these are niche hosts, etc. but it seems people talk about them in the blogosphere.

I signed up to Uni-Hosts (Universal Hosts) a couple of days ago after seeinf one of they're deals in the Deals Forum and I'm still waiting for activation.
Is there anyone here with Uni-Hosts or had experience with them?
I was initially impressed with the deal but I'm getting unimpressed very quickly with they're setup times.
