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.

Code:
find /usr/local/lib -name 'php.ini' | xargs perl -pi -e 's/extension="eaccelerator.so"/;extension="eaccelerator.so"/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="eaccelerator.so"/extension="eaccelerator.so"/g'

Windows 2003 Eaccelerator Cache Cleared Randomly
I have successfully installed eaccelerator on my win2k3 box and it is working great. The problem I am having is that every so often the cache files are mysteriously cleared. I know that the cache is cleared when apache is restarted but I have not restarted it and the files still go missing after a period of time. I have the ttl values for ea set to 0 to disable them.

Here is the ea ini in php.ini:

extension="eaccelerator.dll"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="C:Cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="0"
eaccelerator.compress_level="9"
eaccelerator.allowed_admin_path = "D:WebsitesThe Family Garrisoncontrol.php"

I am running php as php-cgi.exe with MS fastcgi enabled on a 32bit system.

Eaccelerator Eaccelerator.shm_ttl
Does anyone have a recommendation for the eaccelerator eaccelerator.shm_ttl setting? If it was left at the default of "0", this means no newer scripts would ever be cached once the memory is full. Or would it do additional caching on disk as well and not show up in the phpino.php file?

We have alloted 32 Megs of Ram for eA. Maybe something like this would help move some old scripts out of the cache?

eaccelerator.shm_ttl="86400"
eaccelerator.shm_prune_period="0"

Eaccelerator
When eAccelerator doesn't have enough free shared memory to cache a new script it will remove all scripts from shared memory cache that haven't been accessed in at least shm_ttl seconds. By default this value is set to "0" which means that eAccelerator won't try to remove any old scripts from shared memory.

Does that mean that once the shared memory is full, that even if a script that is in shared memory hasn't been accessed in 5 months, any new scripts will have to be ran off of the compiled versions on disk instead of being read out of the much-faster RAM?

SuPHP Or EAccelerator
I have a Linux server for shared hosting in which I am using Cpanel/WHM. I have PHP running as suPHP which I believe is for security. The problem I am facing is a lot of PHP based websites create load on the server and consume as much as 10% of the CPU and sometimes some script even consumes 50% CPU. I think I can reduce the load caused by the PHP scripts by installing eAccelerator. However, it does not work with PHP running as suPHP. Can anybody tell me which one should I choose of the both? Is there any other way to reduce the load on the server?

Installing EAccelerator
I successfully installed eAccelerator and its already working fine then I decided to update my PHP version which is 5.1.6 to 5.2.6 after the upgrade eAccelerator is no longer loaded I tried recompiling eAccelerator but to no avail it doesnt load anymore I double checked eaccelerator.ini and it was already set. Someone said that the phpize that was installed in my server is not compatible to PHP5.2.6 and it needs to be updated also but I cant seem to update it since it always says that it is already updated.

I am using CentOS5.3.

Install EAccelerator
I've got a CentOS 5.0 machine running PHP 4 & 5 in FastCGI mode with suPHP.

I've read the instructions to install eAccelerator at: InstallFromSource - eAccelerator - Trac

However there is a line at the beginning that says it is safe to follow those directions if you have ONE php install.

I have php5 as default and php4 optional. Does this count as 1 or 2 installs?

EAccelerator Error
Everything was working fine until I upgraded from PHP 5.2.0 to PHP 5.2.1. I compiled from source to upgrade, and I installed PHP 5.2.0 from source. Once I upgraded, eAccelerator complained that I had to recompile it again for it to work on 5.2.1. I did and it gave me the same error. I recompiled maybe 10 times and it has still complained about it. How do I fix this error?

EAccelerator And Zend Optimizer
I am using PHP 5.2.1 (recently upgraded), Apache 2.2.4.

Before the upgrade, I had Zend Optimer and eAccelerator installed.

However, after upgrade of Apache and PHP + I had to reboot the server, I went on to reinstall eAccelerator.

Here is what php -v gave me :

=================
eAccelerator requires Zend Engine API version 220051024.
The zend Engine API version 220060519 which is installed, is newer.

contact eAccelerator at http://eaccelerator.net for a later version of eAccelerator.

Php4 Extension (eaccelerator) Not Loading Anymore
Server :
pentium IV 3.0 Ghz
debian 3.1
kernel 2.6
apache2
php4.3.10

Some months ago I installed php4 on this server , and added eaccelerator.net , mostly with this site as guide. Everything worked fine.

Few days ago I realize I hadn't updated this server for a while. I run 'apt-get update' and 'apt-get dist-upgrade' . A whole lot of things get updated, and after that I perform a reboot, as adviced by the update script.

The next day I experiment a bit with the profiler of xdebug . I manage to install it , play around with the results, but decide to uncomment it from php.ini again as it is not that helpfull to me and it makes quiet big log files too.

Today I notice this server is getting very big loads. Normally on peak evenings it would float around 2-4 , with sometime jumps to 10-12 but always quickly recovering and working well. But on this evening it kept rising, stayed around 30-60 for most of the time, and even hit up to 85 . It only lowers when the busy hours are really over. So I look around everywhere , and then after a few hours I notice that eaccelerator is not visible in phpinfo(); anymore. This is the only weird thing I could find, and I assume this caused a big difference on the performance.

I dont know why exactly it went away. Maybe it was the server update, wich touched a lot of files. But I thought it was not supposed to update any configuration files, not without warning at least. I could also have been the xdebug script, wich also uses 'phpize' to install and also required editing in php.ini . I really wish I noticed the lack of eaccelerator after the update but before trying xdebug.

So I try to install eaccelerator again. Unpack from source, phpize, make, etc etc, just as last time. I edit php.ini to make sure the load command and settings of eaccelerator are still there and reload apache. I check phpinfo(); , but nothing changes. I try it all again to be sure, but still nothing. I check the location of the .so files, yes they are still there and the rights of the files look ok.

I edit php.ini again and uncomment 'extension=mysql.so', and reload apache. I notice a mysql error on my site as expected. So that means I'm really editing the right php.ini file and that I can influence the extensions that are loaded. I add the mysql extension again and reload apache.

I load an old php.ini backup file, from right after first installation of this server. The eaccelerator settings are there too already, but if I try it and reload apache : no difference.

I reboot my server again, because .. well sometimes it helps. But not with this. phpinfo(); still says no eaccelerator.

I check another server, exact same specs, same php+eaccelerator installation on the same day as the first one. I compare versions of apache/php/php extensions/zend extensions and all numbers I can find. Everything still looks the same, except server 1 does not have eaccelerator and server 2 still has.

I'm shomehow out of things to check now. I'm pretty sure eaccelerator has a big influence on the performance of my heavy php site, and I want it back. Everything looks ok, the files are there, the settings in php.ini are there, it should work ... but it doesnt. No errors or warnings anywhere, just phpinfo(); saying that eaccelerator has not been loaded and the high loads are confirming this.

It will either be a very complicated solution, or a very simple one, but I'm just looking over it. Does anyone has any tips on where to look or what to try ? Thanks.

Enable Zlib Compression If EAccelerator Is Already Installed
Does it make sense to enable zlib compression if eAccelerator is already installed? I'm running PHP 5.2.1 (FastCGI) with lighttpd 1.4.13 and eAccelerator 0.9.5. Also, here's a more general question.

Opcode Caches And Segfaults (XCache, EAccelerator)

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.

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
[url]

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%';

outputs

+-------------------+---------+
| Variable_name | Value |
+-------------------+---------+
| have_query_cache | YES |

which indicates that cache is set, but...

find . -name "my.cnf"

./usr/local/cpanel/whostmgr/my.cnf
./etc/my.cnf

shows only these

set-variable = max_connections=500
safe-show-database

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?

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?

DNS/Proxy Cache
I made changes in httpd.conf to redirect website to another website; after 15min I removed redirect but until now when client request website they are redirecting.
I'm sure I remove redirect.

we are locating in UAE, UAE has transparent proxy for all Internet connections so I think the problem in proxy cache, How i can confirm it? then can I avoid it ?

also when I put dot "." at the end of link site working without redirect otherwise it's not working.

How To Troubleshoot Mmap Cache Problems
Could someone please help me with some information on how I can troubleshoot this issue?

[warn-phpd] mmap cache can't open /home/sitedir/)

It's happening on all the directories ie: sites on the server. Switching from phpsuexe back to running php dso fixes the issue, but how can I run phpsuexec and fix this problem? Any tips would be very much appreciated.

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?

Media Serving And Cache Daemon
what I want to do, have a "node" somewhere serve media (static) files from a central server, but cache the static files the first time they are hit, so subsequent requests to the "node" don't require getting the file from the central server.

Is there readily available solution to this?

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?

Server:

Quote:

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
6 GB DDR PC3200, ECC, CL3
2 X AMD opteron dual cores (4 X 2.0 ghz)

Cache The Dynamic Url (images)
I've got an application (java web ) tha dynamically creats images ( with dynamic url - ...tab&vi=nia&h=24&ds=bottom&fn...) - 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.

PHP Accelerators (cache) CONS
I am currently wanting to add a cache engine that eases the apache server for my php scripts. I just wanted to make sure there weren't cons; bugs with certain pages that need to be reloaded very quickly? Has any of you already experienced such bugs with these progs? Which cache-accelerator would you suggest for php-mysql apache?
