Virtuozzo Centos 64-bit Vps Not Using Any Ram For Buffers Or Cache
I have a virtuozzo vps account 64-bit centos running whm/cpanel.

I've been having an issue with high load average at times while very little cpu is being used and there is plenty of ram free, and in looking into this, I've run into another thing that seems very odd to me:

total used free shared buffers cached
Mem: 786432 179944 606488 0 0 0
-/+ buffers/cache: 179944 606488

top - 22:29:52 up 15:30, 1 user, load average: 1.23, 1.55, 1.12
Tasks: 74 total, 1 running, 72 sleeping, 0 stopped, 1 zombie
Cpu(s): 0.0%us, 0.1%sy, 0.0%ni, 88.8%id, 11.0%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 786432k total, 174784k used, 611648k free, 0k buffers
Swap: 0k total, 0k used, 0k free, 0k cached

uname -r
No memory being used for buffers or cache.

why no ram is being used to buffer/cache slower disk io?

I Have To Flush Iptables On Every Reboot
I'm running CentOS 4.4 32 bit.

At the moment every time I reboot my server I have to execute:
# iptables --flush
# iptables --zero

just to be able to access the server. (Though it does allow SSH to access before executing those).

And I figured out that I must do something to /etc/sysconfig/iptables to permanently be able to access the server without those commands after reboot. Right?

Below is the file's contents:

# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT

-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

What do I need to do?

After Flush+zero Iptables, Will A New Iptables Ban Work
I execute the following commands, in the following order:

If not, what needs to be done? I can't access my site if I don't flush + zero iptables first but I need to be able to ban with iptables.

PHP And Cache-Control
I seem to have the opposite problem of what most people complain about... I'm using some custom-built PHP scripts, the output of which is not getting cached. I want the output cached, because it doesn't change often.

If it's relevant, I'm using ob_start() to serve up a GZIP-compressed page.

I start off with a header("Cache-Control: maxage=3600, must-revalidate"). Yes, it's first, and yes, it's showing up properly in the browser.

However, requesting the page again returns an HTTP 200, not the 304 I'm expecting. It's pulling down the whole page again. It's not changing in between requests, and I'm simply visiting the URL again, not hitting Refresh. (Although it really shouldn't matter.)

Mysql Cache On A Vps

has an article on mysql query cache.
It notes that in the mysql config file, having

query-cache-type = 1

sets the mysql query cache.

In mysql I note that

SHOW VARIABLES LIKE '%query_cache%';


| Variable_name | Value |
| have_query_cache | YES |

which indicates that cache is set, but...

find . -name "my.cnf"


shows only these

set-variable = max_connections=500

So where has query cache been set?

At the server level?

If so, am I able to set the query_cache_size and if so, which path?

Anyone have any comments on their mysql optimization on a VPS?

Getting Around A Corporate Proxy Cache
I'm assuming a corporate proxy cache is what they have set up. I have a client and every time I send them changes to a temporary page I'm hosting for review they can't see it.

They can hit refresh over and over but never see the new updates unless I change the name of the folder its in.

This is very annoying and it only happens with them and one other corporate client i have. They check on multiple computers and it will never refresh and load the new changes. I think this is their network cache that their IT dept. set up.

How can I get around this? I tried an htaccess trick I looked up for expiring files but it didnt work.

These files are on a shared hosting of mine on an Apache server.

Sda: For Cache Data Failed
We just upgraded our server with 8 brand new seagate cheetah 15k.5's, a battery backup unit, and a 256mb dimm for the raid controller. In the boot process, i noticed an error about caching or something.

After analyzing the dmesg log, i found the error:
sda: asking for cache data failed
sda: assuming drive cache: write through

It seems like the kernel can't get to the raid controllers cache, so it switches to the write through setting.

I've benchmarked the harddisks with the write through, and write back setting. The odd thing is that both settings deliver the same performance.

Normally, write back increases the performance with like 100%... That's why we bought the battery backup unit.

So something is going wrong, but where lays the problem?



8 X seagate cheetah 15k.5, U320, 16mb cache, SCA, 73GB
1 X chenbro backplane, U320, SCA, 2 channels, 8 ports
1 X LSI megaraid 320-2x raid controller, U320, 2 channels, battery pack and 256 upgraded dimm

Dispatch.fcgi Kept In Cache
I have Django (python framework) on a server, and I have a little problem. The application is kept in cache by FastCGI

When you make changes to your application you have to restart it. Touching the file doesn't solve my problem. The only solution I have is renaming the .fcgi file always, and if you use an orifinal file name, it actually works like before, prooving it's kept in cache.

What would you do? A cron job to remove these files maybe?

Cache The Dynamic Url (images)
I've got an application (java web ) tha dynamically creats images ( with dynamic url - - like thumbnails,icons ect.

The think I'm trying to deal with is to force caching theese images by a browser.

When the application starts the server gets images and shows code 200 ( and this images apppers in web browser cache), but after reloding or simply viewing the images from the cache url the server shows again code 200. I'd like to have code 304 - not modified - like when browser gets an image from cache.

The dynamic url for image is being created only once - when the appication starts, and after that it stays unchanged, but I still can't force use the cached images - like when it is a static url - .../image.jpg.

When To Add More Ram. Swap/Cache/Buffer
When is a good time to add more ram?

Since I got my server its ran with 1gb ram and has kept a free of at least 400mb since that time.

Now withing a few hours all of it is being kept in buffer/cache as the past week an showing about 15mb free (not counting buffer/cache) and has started in on the disk swap of about 400Kb.

So should I upgrade to 2gb now or wait till it goes deeper into the swap, and if so how far into the swap before you'd upgrade?

Eaccelerator Cache Emptying Cron
I'm sure all of you who use eaccelerator know how big the cache can get and that it needs emptied manually. Well at least to my knowledge it does, the only thing I have seen that you can configure is the shm pruning. If anyone does know such a feature with eaccelerator please share. But I also notice a performance decrease and a few php errors mostly related to memory allocations here and there.

Anyway I was piddling around and came up with a command to disable eaccelerator from php.ini, delete the cache folder and then enable it back. I figured this would be good as a daily cron. I would like some input if anyone knows any better ways.

So I wanted to share this in case someone else here has the same problems with eaccelerator cache folder getting huge. If anyone knows a way to make this better or shorter please reply with solution.

Of course this will vary depending on where your php.ini is and where your eaccelerator cache is. Just replace those values with yours. I'm sure there is also a way to use similar commands to find and input these values, again if anyone knows please share.

find /usr/local/lib -name 'php.ini' | xargs perl -pi -e 's/extension=""/;extension=""/g' ; rm -rf /usr/lib/php/eacc ; mkdir /usr/lib/php/eacc ; chmod 4777 /usr/lib/php/eacc ; find /usr/local/lib -name 'php.ini' | xargs perl -pi -e 's/;extension=""/extension=""/g'

Cache Systems For Apache In Windows
I have a fair ammount of load on the server, and I want to cache as much as possible to reduce disk IO. The harddrive is a major bottleneck for performance. The server serve a lot of files larger than 10MB, so I want to cache as much of the files below 10mb as possible.

First off I want to cache around 200k thumbnail files, where around 1000 new gets added every day.

Secondly it would be preferred to cache dynamic files in a way that the file timestamp is checked at a regular interval, and then read again if timestamp has changed.

Is there any free solutions on windows with apache for this?

HTTP Headers & Cache-control
I was running into a problem where PHP was automatically sending the following HTTP headers:

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache
This caused a problem in that my browser (Camino) would not let me view source without reloading the page. For state-based pages, that was a nightmare and meant I couldn't use my main browser for development!

Now that I have identified the problem, I am wondering what the point of those headers are, and whether I need them. I can definitely overwrite them but am not sure if I should.

My web app does set cookies (uses PHP sessions). I believe that it is the setting of the cookie that triggers PHP to send those headers. If I don't set a cookie on a PHP script, those headers are not sent.

how I can manage cache-control properly so that I can view source in Camino? Is no-cache etc. really important if you're setting cookies?

Raid Card - Write Caché - SAS 5/iR
I have bought 4 servers with DELL SAS 5/iR.

All is fine but the writes are very slow; I supose it's because write cache not enabled.

I have enable it and make some test and there is a lot of difference:


I'm worried about enabling it because if the server goes down I think it can cause disk corruption and loose data and maybe the OS. What do you think about that? Data is a priority!

Disks have this technology: Seagate-exclusive IRAW (Idle Read After Write) enhances data
protection by verifying—during drive idle time—that data in thedrive buffer was properly written.

The servers are on a datacenter and have RAID 1 with Cheetah® 15K.5 SAS 3Gb/s 146.8-GB Hard Drive - ST3146855SS

I'm also VERY worried about the coments about this card:


Is it true that the raid don't get rebuilded? If it is like this I don't know why I'm running raid.

Mod_cache Does Not Cache The Homepage But The Rest Is Cached
As many of you may know mod_cache does not cache directory index
files, this can be fixed with mod_rewrite but the index page of the domain (the homepage) seems to be impossible to cache it. The following rules cache the folders but not the homedir (this means that is cached but is not):
DirectorySlash Off
RewriteEngine On
RewriteCond %{REQUEST_URI} ([^.*])
RewriteCond "%{DOCUMENT_ROOT}%{REQUEST_URI}/index.htm" -f
RewriteRule "^(.*)$" "$1/index.htm" [NC,L]
RewriteCond %{REQUEST_URI} ^([^.*])$
RewriteCond "%{DOCUMENT_ROOT}%{REQUEST_URI}/index.html" -f
RewriteRule "^(.*)$" "$1/index.html" [NC,L]
RewriteCond %{REQUEST_URI} ^([^.*])$
RewriteCond "%{DOCUMENT_ROOT}%{REQUEST_URI}/index.php" -f
RewriteRule "^(.*)$" "$1/index.php" [NC,L]

Note that DirectorySlash should be off (or mod_dir not loaded) in
order to work also with URL that end with no slash

As I said before this will work for any folder but it does not work for public homedir
directory. So when a user visit [url] it does not
work (unless you type the name of the index file: [url]

For me it is critical to make this work in someway, the index homepage
is the main page that needs to be cached in my case (and in many

Do you know any solution for this? I found the first message about
this in the Internet in 2002 but I'm using last version of apache
httpd and still does not work.

If you have no idea about how to fix it, maybe you know some other easy alternative. Lighttpd + mod_cache + mod_deflate are not compatible: "mod_cache can be used in conjunction with other lighttpd plugins (except mod_deflate and mod_secdownload)"

Is There Such A Thing As A Content Cache, Like SimpleCDN But Not So Sophisticated?
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 To Cache/proxy Streaming Content - More Details Inside
I've got a dedicated server running my portal. Now we plan to soon launch broadcasting, where we via a webcam + microphone will broadcast (streaming WMV media) to all our members. Our members will then be able to interact with the speakers via chatting.

Now we are currently undergoing loadtesting, with our current setup, which is:

1. dedicated server+ultrafast connection=>chatting

2. home PC with static IP and 1 MBit upload=>Video+Audio Streaming

So the member requests a page from the dedicated server, which has a chat window and a windows media player. The player will retrieve the video/audio content from the home PC. This is done by the client.

Now is pretty logical to see that there will be limitations in how many connections the home pc will be able to handle.

The question is: How do i make the dedicated server get the content from the home pc (so it only serves one connection) and then get all the clients to get their video content from the dedicated server ?

I've looked into the proxy modules for the apache server, however they (forward/reverse proxy) both passes the connection on to the remote machine and thereby not doing what I want to do.

does mod_cache use real disk space or real memory to locate "cache"? I mean if i use mod_cache, does my vps/server will use more disk space/memory?

Domain Name Server (DNS) Cache Problem? Or Server Problem?
I just migrate my server into IWeb, the server working great and in reasonable price but the problem is this server give me some funny problem. Anyone can help?

Basically I am in Singapore. My Website which suppose to show english content somehow become mass question mark as below. I am Sure that its not coding problem or Encoding problem since last time it can working fine (it happen only after I migrate the server from layeredtech into here)

But the content will show correctly if you open from US IP or other proxy server. I try in many computer here , some computer show error as I have. So its not computer problem as well since many computer see same error.

It will working fine again after I download and reupload the file but it will back again after 2 weeks.

Is it anything wrong with my server? or dns server setting? why only shown the problem from singapore-malaysia and indonesia side?

Some people say it because error on my DNS ISP , but I dont think so since many people in those country see the same thing. Any idea what should I do?

Getting GUI On New CentOS VPS
linux and after several days testing different distributions and a bunch of different ways (e.g. freenx,vnc XFCE ...) I've decided to setup a vnc-server on CentOS-5-i386-minimal and use KDE as a desktop environment.

After reloading my vps with centos-5-i386-minimal, I logged in as root and executed:


yum update

yum -y groupinstall "KDE (K Desktop Environment)"

yum -y install vnc vnc-server firefox X11 xorg

I then added a user "abt" and set the password. Then I logged in as abt and execute : vncserver, it asked for the password and created the appropriate .vnc directory and files.

I then edited xstartup file and replaced "twm &" with "startkde &" and executed vncserver once again, this created desktop number 2 for me.

The problem is that after running TightVNC(on vista) and entering IPNUMBER:2, It successfully connects to vnc-server but what i get is a black screen with X cursor!
