Wierdest Thing EVER Eth0 Drop W/ Plesk Usage

Jun 1, 2007

I just got my servers up, DNS servers what not and my main plesk server for shared/reseller hosting.

Now for the weirdest thing ever!

I started working on my plesk packages a few days ago, after I got plesk installed.

Systems stats as follows

Supermicro AS1021M-T2 barebone
[url]

Has 16GB of infeon DDR2-667 memory.
2 250GB hard drives in mirrored configuration with the Acera 9500 w/ 256MB of memory

Running Cent OS 4.4

For some reason, Everytime I go into Plesk, or any of the websites that are contained in Plesk, The nic card drops out, wont allow any activity to get through, both ways.

Plesk 12.x / Windows :: Drop Unused Listed Databases

Feb 24, 2015

Plesk12 has been installed on Windows2012R2. In the Tools and Settings/Database Servers list we have

· Local MySQL server (default for MySQL)
· .MSSQLSERVER2012
· sql-db-1 (default for MS SQL)

We only expect to use the remote sql-db-1 database for user databases.

Can we delete the other 2 databases and is this recommended? Does the Local MySQL server contain the Plesk Management database/schema?

No Such Thing As The 10/10 Provider :p

Nov 17, 2007

so after 16 months using vps servers i thing i have it all cleared up. There is no such thing as the 10/10-allmighty-everything-is-so-good provider it all depends in what are you OK with.

Now t3h facts, what i care about a provider is
- Price
- Performance
- Uptime-AKA-Reliability
- Provided Resources

I've been with 4 different providers (SolarVPS, Knownhost, JarguarPC, FutureHosting)

I will not do a long review but i will tell you some facts of my experience with them.

I started with SolarVPS (Mercury Plan 256MB-384MB-10G-200G-Cpanel-unmanaged-33.75), i started having a lot of problems, black zone alerts every day most of the time, bad performance, the server felt really slow, but after many months in the vps market i think it was because 256MB with Cpanel don’t play well, specially if you have a busy forum that needs many apache childs and lots of mysql usage. After 1 months using it i jumped off the ship to Knownhost. I started blaming SolarVPS but then i realized it was because 256MB weren't enough for my need. So i can't really talk about them, only 3 weeks but i don't think ill be going back , maybe providers shouldn’t offer Cpanel with 256MB systems.

Then the Knownhost Experience (384M-768M-10G-175G-Plesk-semimanaged-42.50), Now after a bad first experience I wanted to go back to shared, but seeing a lot of good reviews about a starter company at that time, I decided to go with them, I used them for 11 months, I can tell you they are reliable, they are good priced, but the performance was my problem.

For example running WHT-UnixBench scored like 60-80 on knownhost, and I had problems with mysql, a lot of queries took too much time and I kept having visitors to the point that apache always reaches the server limit and mysql just wasn’t ready to give the results, so the server also reached the memory limits and virtuozzo killed some services and all that, to the point that just wasn’t ok with it so I started looking where to move. If you need some reliable service, looking closer to that 99.999% uptime and don’t have too much of that resource intensive sites, then imho knownhost is your choice.

I do not know that much of Microprocessors but what I hear is that at this time Intel is really better than AMD, but knownhost stays with AMD for many reasons im sure, I just think that the servers would be a lot faster if they were using Xeons instead of Opterons, but once again I’m not 100% sure

Ok now this is where JaguarPC comes into play, when I was looking for the new provider I find out that Jag was running an awesome deal, if i was moving from another provider they will give me 2 months free, and a lot of specials ->(384MB-1G-30G-450G-fully-managed-Plesk-33.50) <- , so that looked like a really really good deal, I did not hesitate and signed up quite fast.

Started up really bad, when they servers were badly configured so they had to restart the entire node to fix settings many times, virtuozzo was going crazy killing processes and all that, but they fixed it and after 5 months with them everything is really good, then only problem is the reliability-uptime, I can’t get above 99.89%, they have many downtimes, call it “fixing settings”, call it “patching kernel”, call it “getting better”, still it is a downtime, it is a client calling you cause they cant access the mail, or something like that. (BTW im monitoring the server with host tracker).

So why am I staying with them? , because I get a better Prices $$$ , I get more resources, and at this moment my business does not require 99.999% , im ok with 99.9% uptime, and also my sites works really faster, mysql handles the load like a champ. But if they could increase the uptime they will be the closer to 10/10.

If you noticed I didn’t mention futurehosting its because I use them for small experiments, like lighttpd, server administration, as backup server, and other administration learning related tasks. But the servers works really good, im using the Chicago DC and getting better latency than Texas

I hope some day I will use futurehosting more and give a proper review, right now im using the 384MB_SLM-10G-200GB-NoPanel-20$ , everything looks quite good but running unixbench scored less than jaguarpc.

Its just a matter of what you need, and what are you OK, im a student and give hosting to friends and family, I have my own forum that gets many visitors and it is really database intensive, so at this moment im staying with jaguarpc and hope to continue that way

Dec 23, 2007

If i have 2 NIC on my server 1 for private and 1 for public

if the public is eth1 than in the config of APF

IFACE_IN="eth1"
IFACE_OUT="eth1"

I should set it to eth1 instead of eth0

is that correct?

Is There Such A Thing As Backup Internet

Aug 8, 2009

I have built a few servers at my home office.

I wanted to ask if there is a data center that might provide additional band wish or backup internet.

By backup internet i mean.

If my internet goes down. It will still be running on a second network.

Not sure how that would truly work however.

My server does connect wireless and the speed is excellent.

However like every provider at times it can go down. Weather, Maintenance etc.

[Mods if this is in the wrong forum just move it to the correct one i think this is the place to put it however]

Trafic -in- On Eth0, Normal Or Not ?

Jul 1, 2009

I'm not sure if the trafic showed by munin graphics is normal or not because it seems it jumps to 2mbps in the morning and after few hours drops down to .5mbps

I don't host any storage websites, which should have lots of uploads, just normal websites, maybe a total of 10000 unique visitors/day on all accounts (I estimate this as I don't know how to find out exactly the number of visitors on all websites hosted on this server - 182 accounts)

My question is how can I see what exactly is making that trafic, maybe using a netstat command to see what processes are using the bandwidth.

Jul 31, 2007

say you run a script like DIGG and then it just became huge and huge and one day u find out that a server cannot run it alone, that is u need to get multi servers to cope with the traffic and database requests. How would people go about doing that? Is it the script implementation side of change or just server side of change?

Firewall Blocks Server (or Eth0) Itself

Jun 1, 2007

I just uninstall apf and install csf firewall on 4 servers

There is a problem after that. 2 of the server actually was OFFLINE by 12 midnight sharp yesterday night. This is the second time (second day) it happens.
I went into the datacenter and

#ping yahoo.com
*Host not found*

#service csf stop
#ping yahoo.com
*Responding*

So how is this related to eth0 making my server offline by itself? Was it Iptable problem or Csf problem? or Kernel problem?

Is There Such A Thing As A Content Cache, Like SimpleCDN But Not So Sophisticated?

Apr 9, 2009

I have a site where our budget is very constrained, and we're maxing out our unmetered pipe. The majority of the bandwidth is taken up by an active forum.

I offloaded most of the static content (images, .js, .css files) to a CDN (SimpleCDN) which I've been pretty happy with, the costs are very reasonable and fit within our limited budget.

They offered a service where if the content was not found on their network, it would check on our server for the file, retrieve it, and then serve it up from then on. Which was perfect for us as it allows us to use the CDN to serve image files uploaded by users in such a way that it's transparent to the end user.

However they're discontinuing this service, and though they're offering a similar service (based on rsync), they're charging $150 setup fee! So basically I have to pay $150 to keep using the service I've been using for a while. Which I can't really do.

So I'm trying to think of alternatives. I don't think I really need a full bore CDN, while we do have users from around the world, it's not a business site so a few ms isn't going to be the end of the world.

I just need a file hosting solution that has decent performance and fairly inexpensive bandwidth.

It's only 100-200GB / month maybe. At SimpleCDN that was only costing $8 / month.

I looked at Amazon, but they charge 1 cent for 10,000 requests which for us adds up very fast.

I'd almost think of just signing up for a Dreamhost account, but I would think using them to host just our images probably goes against their ToS.

How Does Server Notice Period Thing Work

Jun 2, 2008

I have a dedicated server with a provider. They have a notice period of 30 days, to cancel the server. The billing date of the server is 13th of every month.

I sent them the cancellation form on 30th of last month, asking them to terminate the server by 1st of next month (thereby 30 days notice). But they say that they will bill me on this 13th for another full month, and they'll cancel the server only on 13th of next month! WTF? So, the notice period becomes 43 days!

I have never experienced something like this with other providers I'm using but just wanted to know..

Munin Stopped Reporting Eth0 After Reboot

Apr 30, 2008

I rebooted my server and now munin is not showing any eth0 traffic. All other graphs are fine. I can see there is a ton of apache accesses so there is definitely eth0 traffic. Munin logs report no errors. I restarted munin and munin-node. I even did 'yum remove munin munin-node' and reinstalled again but it still doesn't work for eth0.

/etc/sysconfig/network-scripts/ifcfg-eth0 Of One Of Your Nodes

Dec 3, 2008

I am having network issues, local servers in the /24 are unable to connect to VPS's.

If I make the /etc/sysconfig/network-scripts/ifcfg-eth0 too especific by adding a netmask then Nodes with assigned IPs on a different /28 will stop working/ping.

Right now it works, but it doesn't allow local servers to connect to VPS's (a problem) as one of those nodes is a VPS backup center.

Restarting Mysql/named If They Drop

Dec 22, 2007

way to restart mysql and named if they drop. I'm on cpanel.

I've searched and found the following:

For mysql:

Code:
NUMBER=`ps --no-heading --user mysql | wc -l`;
[ $NUMBER -eq 0 ] && service mysql restart;
For named:

Code:
NUMBER=`ps --no-heading --user named | wc -l`;
[ $NUMBER -eq 0 ] && service named restart;
I have these set to run every 5 minutes, just to check if mysql/named are running. I found out that it doesn't work: I woke up to a whole bunch of sql errors and realized that mysql dropped while I was asleep... I type in "service mysql restart" manually and it restarts as usual, so I know that the command to restart sql works fine, but the restarts aren't triggering in the first place.

100 Day Review Of LiteSpeed (Apache Drop-in Replacement)

Aug 14, 2007

(This is the first review I've ever written for practically anything so please bear with me. I feel the need to share my experience to try to help others after all the great advice and info I've received around here.)

If you've done everything you think you can do to improve the responsiveness of your websites like add a mysql cache, PHP opcode cache and various other tweaks, I discovered there is still one more easy thing you can do for a big improvement: replace Apache with LiteSpeed. It's way too easy not to try it and you can leave Apache completely intact to go back to at a moment's notice if you so desire.

I call LiteSpeed a "drop-in" replacement because it uses all my httpd.conf and .htaccess settings without modification. This was critical for me as my sites have some very complex rewrite rules. Other solutions like LightHttpd require extensive work to make changes if you use fancy mod-rewrite rules. LiteSpeed does not need any fiddling. LiteSpeed just adds it's own clean little web interface so you can tweak if you want to, but I didn't really have to change anything. Last but not least, LiteSpeed gets along with Cpanel and DirectAdmin without any conflicts. LiteSpeed's so compatible I can literally do this on my server and the visitors don't even notice the difference (except speed of course!)

service httpd stop
service lsws start
(and visa versa)

I discovered LiteSpeed after reading that the main WordPress.com site had switched to it and had great success (they have a quarter million registered bloggers and of course many millions more daily readers).

The main reason I tried LiteSpeed is because it's roughly twice as efficient in memory use and performance than Apache 1.3 & 2. It runs PHP up to 50% faster than Apache and static files get served several times faster (faster than thttpd & lighthttpd). So this means you can either double the number of active connections you currently max out at now, or make a regular website respond nearly twice as fast, or under heavy loads still respond within a reasonable amount of time when Apache would be completely unresponsive.

The last situation was exactly what I was hoping for and LiteSpeed helped me keep my sanity on a bad VPS node.

Basically a couple months into owning my first VPS (after many years of shared-hosting experience) I started to realise many of the industry promises about VPS are an outright lie. You are far from isolated from your neighbours. Any disk load created by bad neighbours, mysql abuse or otherwise, will directly affect you and you are powerless to stop it. It's the most poorly regulated resource on any VPS node and it can be made worse by slack, ignorant or inexperienced hosts who do things like move accounts during busy periods onto and off a node at the root level which ties up the entire node for an hour or more. Under Apache, I was getting timeouts during peak visitor times and that was very upsetting.

On top of my VPS neighbour troubles, no matter how I fiddled with Apache's settings (with all the helpful guides around here) I could not make it comfortably fit within the guaranteed memory limit of my VPS with Cpanel, which I really wanted to keep as it's much easier for my end-users. Switching to LiteSpeed caused a radical drop in memory use. I've seen nearly 1000 people online within a one minute period on one of my sites and it still fit comfortably within my memory limits and stayed extremely responsive.

I've discovered another plus to LiteSpeed along the way that no-one else seems to mention. It's the only server software that "out of the box" seems to serve web compressed (gzipped) pages properly as chunked output. This means a visitor will start to see the page immediately as soon as the first part is sent vs. on Apache, mod_gzip actually de-chunks all the output, waits for it to finish, then compresses, then sends.

Mod_deflate on Apache 2.0 was supposed to fix this but it usually doesn't work properly and I've never gotten 2.0 to do compressed+chunked output on my sites without alot of fiddling and help from PHP. It also doesn't seem as smooth as LiteSpeed's output which gives you that "silky" watch-the-webpage render effect that's mentally rewarding to visitors.

On the downside, there is one reason you wouldn't use LiteSpeed - if you use highly customised Apache mods. LiteSpeed cannot support custom mod's and their directives. It does have a lot built in however that Apache does not, so you may way to examine if you can accomplish what you are trying to do another way.

I started with LiteSpeed 3.1 and when I found an incompatibility with an obscure Apache feature (ie. ErrorDocument's as plain text output: ErrorDocument 404 "Not Found" was not supported) they fixed it for me in a day or so after I reported it on their forum. The same for PHP support of "Apache_Response_Headers". Note I am not even a commercial customer! They are now up to 3.2 which has a few other fixes.

The free version of LiteSpeed has a limit of 150 simultaneous connections (plus the linux stack of 200 more which will backlog). I've never seen that limit hit. It's so intelligent about closing connections as needed that it's not an issue for me. Perhaps on a dedicated server with many virtual hosts this will be a problem. Up to version 3.1.1 that was the only limitation, however unfortunately in 3.2 they have decided to also limit virtual hosts to "5", so that's something else you'll have to consider if you want the free version, otherwise the commercial version has a free trial and money back guarantee.

Some people were upset with me that I wouldn't name my VPS host when I was constantly complaining of troubles but that's just my style when I have nothing nice to say still have to do business with them, so don't name names. But when I have something nice to say about a company, I like to speak up. So I heartily recommend LiteSpeed and hope other people give it a try - especially if you are on my VPS node ;-)

Plesk Vs. CPanel RAM Usage
