I am leaning towards people who made the switch from reseller to vps. I dont know much about servers and getting managed servers become pricy so i just want to know how you learned.

So far I had only dealt with shared hosting. Now I think it is high time to move to a VPS server. But before I migrate, I want learn how to manage a VPS server. Can anyone plz tell me how I can setup a VPS on my system, so that I can learn how to work with it.
View 12 Replies View RelatedI was wondering if anybody had a suggestion of what to look for in a VPS that I could use to learn and grow on. I generated a decent-sized web application (PHP5/MySQL) and I'm looking to grow in userbase and features.
I started it on Lunarpages shared hosting (which was a nightmare) before realizing I needed something a little better. I ended up switching over to WestHost and I've been very happy with them for a few years now. Though some may argue it's not a "true" VPS, it's done everything I wanted it to do so far and been quite reliable. It was a great stepping stone.
My site has been growing, as have my service plans, budget, and aspirations. I like to learn by getting my hands dirty, and I wanted to learn some of the more advanced aspects of running a webserver, so I'm in the market for a VPS with more freedom.
What VPS features or aspects should I keep an eye out for if I'm looking to both learn about the server and expand (aka do development work) at the same time? Benchmarks, RAM and CPU? Upgradability, managed and good support? CPanel, DA, Plesk? Snazzy logos and plan names?

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.

Each server have to host 20 VPS and each server will be 4 cores with 32GB of ram. So CPU and ram should be just fine, my interrogatioon now is hard drives. The company owns the machines, but not the drives yet.
I searched a lot on your forums but found nothing relating on VPS. I'm basicly a DBA IRL, so I have experience in hardrives when it comes to databases, but it's completely different for VPS.
According to my boss, each VPS will run a LAMP solution (having a separeted DB cluster is out of question for some reason).
First, raid1 is indeed a must. There is room for 2x 3.5 drives. I might be able to change the backplane for 4x2.5, but i'm not sure...
I've came to several solutions:
2x SATA 7.2k => comes to about 140$
2x SATA 10k (velociraptor) => comes to about 500$
2x SAS 10k with PCIe controller => comes to about 850$
2x SAS 15k with PCIe controller=> comes to about 1000$
They need at least 300GB storage.
But my problem is that the servers do not have SAS onboard so I need a controller and in my case the cheapest solution is best.
But I'm not sure that SATA 7.2k will hold the charge of 20 complete VPS.
Does it worth it to go with SAS anyway or SATA should be just fine? With SATA better use plain old sata 7.2k or 10k drives?
That's a lot of text for not much: What is best for VPS: SATA 7.2k, SATA 10k or SAS 10k?
how they sell those usb hard drives that connect to the computer that can hold like 100 gb's.....
well if i hook up one of those external hard drives to my server can i use it as webspace for users?
I have read about all of the things you have to do with an unmanaged server, and how beginners shouldn't even try. I am pretty smart though I have a lot of experience with cpanel, and I am not worried about getting my feet wet.
This is the system I want:
Celeron 1.7 GHz
1 GB RAM
80 GB HD
1500 GB Bandwidth
cPanel / WHm
Full root access
How much time would it take to keep the thing running? How do you monitor the server? How do you know when software updates, and patches are available? Can all of the software needed be found for free? What kind of problems would I encounter, and would this be way over my head?

Now basicaly i dont want the hard raid i wana see both 750gig drives.
Now ive bin told u can only do this through the raid bios?
So if any1 has a guide or any helpful comments i would be very gratful.
Its running windows web.
I can install any os i want,Im not very friendly with linux but if thats the only option then id give it a shot.
Now iam useing 320Gig SATA harddrive as my primary hard drive,i dont use 2rd harddrive,iam haveing pure download site,in TOP command 4.5%wa is this bit high? or can i add 2rd harddisk and move some data to there to reduce wa,but my load of the server is fine or any way to reduce wa?
View 1 Replies View RelatedI am running a Fedora box with cPanel...
The hard drive has a capacity of 36 gigs and there's currently 18 GIGs of data on it.
When I do "df -h", it indicates that / has 85% of it's capacity in use. When I run "df -hi" it shows that / has 58% of it's inodes in use.
Is there anything I can do to increase /'s capacity? Can I free up some inodes? All that / contains are folders.

Hard drive arrangement
I have a terminal server with a bunch of applications on it, among which is a database driven app. There have been complaints that access to the db is sluggish. right now the server is on just one 7.2k drive.
I am guessing its a hard drive bottleneck because memory and cpu usage seems okay. I have a few ideas. Please tell me which of these you would recommend.
1. Upgrade entire server to raid 10 system.
2. Upgrade the entire server to a 5-disk RAID 5 system.
3. Create two raid 1 setups. One for the OS and regular apps, the second one to host the DB.
4. Create a raid 1 setup for the OS and regular apps, and a RAID 5 setup for the DB.
Ideally I would like to see improved read/write speeds on both regular files/apps and on the database. The RAID 10 system was what I was leaning towards at first because the stripping increases throughput, but then I realized I may see better performance by keeping the regular files and the DB on independent setups so that OS and file read/writes won't affect the DB read/writes.
On my centos webserver I currently am using a 250gb ide drive.
I just bought 2 Western Digital Raptor WD1500ADFD 150GB 10,000 RPM 16MB hard drives.
And now I am wondering what kind of setup I should have?
Should I have the 250gb hd as a backup drive now and have the two raptors in a raid 0 array.
What would be the best configuration?
I have never had a hard drive fail on me, i dont think the I/O on my servers would ever warrant it but im looking to ask people that have had a hard drive die one them the following:
1. Were you ever cautious before your hard drive failure or did you lose data and if you did lose data, did it make you buck up your ideas (i.e do you now have a solid backup plan or do you still play maverick)
2. If you have had a hard drive failure, has it made you, do you think, overly-cautious?
3. Has a hard-drive failure ever swayed you towards the more expensive raptor drives? and if so, why?
Any advice on setup of remote hard reboot/reset on colocated server.

This site has always been prone for attacks on it's servers. At the moment theres been a new owner and so things are not settled back down yet, How ever people are still atacking the site.
The hosting as far as i am aware has no software/hardware firewall i have tould the onwer but has not taken my advice.
This morning i woke up to find it was being attacked, so i went stright to SSH and started blocking them etc.

The server is a dedicated VPS, and the owner has two sites on which both are forums.
What can i do to protect the sites? What can i do to prevent them? What can i do to stop them.
Week ago I decided to rent another dedicated box , install CentOS 5 64Bit and use LiteSpeed as a web server. What seemed to be trivial at start became nightmare later.
I was unable to compile PHP 5 with --with-litespeed and --with-curl directives. If I removed one of them it was ok but together it didn't work.
Tried to search forums but nothing helped, so I decided to go back to Centos 5 32bit and try there. It compiled OK.
So I'm in trouble now. I wanted to have server with 64bit OS + LiteSpeed because of its speed, system resources consumption and good DOS protection.
I asked several questions about advantages of 64bit over 32bit OS and the most important thing was how much issues can I expect on 64bit OS (libraries availability). Almost every reply said that it's without issues to go with 64bit OS. My experiences say it's not as easy as I expected.
I didn't find any good protection against DOS for Apache so far, mod_evasive doesn't work as I expected. What do you recommend ? Should I stay with apache on Centos 64bit + apache with everything installed via yum (should work OK) or go with CentOS 5 32bit + LiteSpeed there ? LiteSpeed I'm talking about is Enterprise edition.

I just purchased a 500GB ATA hard drive (meant to get SATA but must have misordered, but I don't think it makes that much difference) to replace a 80GB SATA hard drive on a Windows Server 2003 server. There are two partitions on the 80GB drive, and rather than add the new HD as a third partition, I would like to clone the data on the 80GB drive to the 500GB drive, then increase the partition sizes and remove the 80GB completely. Is there a specific method or software I can use to accomplish this?
