Apache :: After Enable APC Pages Throwing Lots Of PHP Notices
Nov 24, 2013
I have installed APC on our Windows server. After I enable APC and restart apache our pages throwing Lots of PHP Notices.
Code :

I run a large service on 2 machines (we're talking 8x2.66Ghz processing power, 4-6GB ram, etc), however we are thinking about creating a node/clustered setup to help spread the load, bandwidth, mysql (having one server for hundreds of thousands of databases is not wise it seems :p), diskspace etc. Lots of machines just seems to be a cheaper and more powerful option.
Would you advise going with lots of lower end machines, or just a few mid-range machines.
Here is what I propose:
3 of these Dual Xeon 3GHZ Dual-Core (4x3GHz) 3GB RAM 500GB Sata Drive 4000 GB Bandwidth 100mbit
or
4 of these XEON X3220 QUAD CORE 2.4GHZ 1066FSB 2GB DDR2 RAM (Upgradeable) 250GB HDD 2000GB Bandwidth 100mbit
or
7 of these Dual Xeon 3.06 Ghz 2GB DDR2 RAM 250GB SATA 2000GB BW/MONTH 100mbit
All of the above are roughly similar prices in total.
I am having this issue with a new box where Apache at random serves blank pages and won't serve anything but until it's restarted. I see no errors in /var/log/messages either to show why this is happening.
It's not all pages either just several various ones. I know it's not a programming issue either because the only thing the server is running is one instance of vBulletin.
I look at top during this and CPU and RAM usage are very low.
The only fix to get Apache to serve the pages is to restart it.
Anyone have any clues on what it could be?
I set my php.ini memory limit to a gig (I have 16 gigs in the sever)
I am delivering my php scripts from a new Apache server on CentOS delivering them only at the end of the loading. What is a pain, especially for pages being used by iOS apps just needing the xml section even if the script goes further, or when presenting information while they are generated.
Looking trough my logs I found something that bothers me, there are bots who keep doing requests on my website with pages like /admin or /secure to find vulnerabilities. It's making about 5-6 requests for unexisting pages every second until it comes to the end of it's dictionary (the pages are even sorted in alphabetical order,
Is there some way to let my Apache server block access to these bots when they make X attemps to see a page who does not exists in a short amount of time? A bit like iptables reject connection if someone tries to log in but fails to do so too many times.
I work for a company with a highly trafficked site (about 100,000 unique daily visitors). We have our "MANAGED" hosting through Rackspace for quite the pretty penny per month. It includes a dedicated back end / DB server and cloud servers for the front end.
The setup has been functioning perfect for 10 months now; but this past Monday the speed of the site immediately dropped. Page load times fell from 1-2 seconds to between 10-20 seconds, and sometimes not at all. As far as we know (and as far as Rackspace says), no server setting were modified. No new code was introduced on our end. It's a mainly static site, with minimal user interaction with the backend at all.
We've monitored the traffic, checked IPs, etc. We've even tunes down several site features in the interest of reducing server load. Upon a server reboot, the active threads/processes running on it IMMEDIATELY jump back up to maxed out levels. It seems like once our daily traffic reaches 10MB/s, a type of queue forms and the delays begin. Rackspace assures us that we're not limited to that.
Versions: OS: cent OS on cloud OS: Redhat on Dedicated Server Apache: 2.2 PHP: 5.3 / MySQL: 5.1.69
Some more background info: The site is typically busiest from 7am until 3pm EST. For the past few days, we've noticed that between 7am and 9-10pm the server has just lagged incredibly. However, at around that 9-10pm mark, something changes and the pages go back to loading almost instantly. (There is still decent traffic though.) Then at around 7am again it slows to a crawl.
Rackspace has offered solutions such as spinning up another server and incorporating their load balancing - they are in the process of this BUT they do NOT think the traffic is the issue. At one point they actually said there was potential packet loss somewhere in the network, but no progress has been made.
I've updated to Apache 2.4.10 from 2.4.9 and all of a sudden my pages don't load anymore.Previously I had this issue rarely and closing the PHP-cgi.exe processes fixed it.But since the update the issue happens almost constantly.
Running Apache 2.2.2 and PHP 5.2.5, and my error_logs are filling up with PHP notices. I'd like to turn this feature off, but I must be missing something here. I've edited the php.ini and set error_reporting = E_ALL & ~E_NOTICE, and reloaded apache, but I still get the same php notices over and over again in the httpd error log.
I'm using Oracle's VirtualBox.My network on the virtual box is set to Bridged Adapter
apache/2.4.7 php 5.5.9 Linux/Ubuntu 14.04.1 LTS No errors in my apache2 error.log file.
First time creating a server on a virtual box. I am not confident i understand how my computer browser access the virtual box server i created. Once i understand that i could fix my issue. Which is, I can't finding my enabled site or localhost via my browser on my computer. All i get is a white page for both. I don't even see the it works page.
I am following this book and got stuck on chapter 1: Understanding and Setting Up Our Development Environment. link to book -- URL...
I have installed Oracle's VirtualBox, mounted Ubuntu, installed apache2 with $ sudo apt-get install apache2 -y. At this point everyone says, now go to your ip and you will see "It Works". Which i do not see. I see a white page with nothing on it. I then looked to see if the localhost /var/www/html/ index. html even exists. Which is does, i opened the file and i can see the line "It Works!".
My hosts file on my computer has ../driver/etc/hosts
I've got a VPS with XenSmart, and I'm running CentOS. Recently, I have been needing to redirect my users to 'www.', since if they don't put the 'www.' in front of the domain the vB forum doesn't run properly. Though, to do this, I edited the .htaccess file and was using the 'mod_rewrite' command, but this requires Apache.
So, on my VPS I've installed Apache, and set LXAdmin to use 'httpd' instead of 'lighttpd', though now my web pages wont show up and all I've got is the default Apache web page:
[url]
How am I able to use Apache (HTTPD) and have it load my current forum? My current forums hosted in:
On 11/29/07, I posted the following question, but have received no replies to date:
Quote:
TITLE: Are frequent failure notices common with VPS hosting?
We have a VPS1 account at Liquid Web ($60/month). Below I have copied just the most recent series of failure notices (clamd, cpsrvd, exim, ftpd, mysql, pop, spamd). We tend to receive these by e-mail on a fairly regular basis, accompanied by the usual message "A restart was attempted automagicly."
Since March 2006, when we first switched our web host to LW, there have been well over a hundred of them.
My question is: Are such frequent failures commonplace (i.e.: benign) on a VPS, or should I be concerned about them?
I usually check our web site after receiving each notice, and it is always up by the time I get there. Nevertheless, it would be nice to know if all these occurrences are considered normal. For example, 19 exim failures over a 6.5-hour span on 9/29/07 do seem a bit extreme.
If anyone reading this thread is technically inclined, I'd like to know what process or hardware state is usually responsible for causing such failures.
FYI, I use cPanel in my web browser to administer the site from a Macintosh computer running OS 9.2.2. I have never used SSH, and have also never read any raw logs. If I did, I'm not sure what they would tell me about this, anyway.
I should also say that our site uses nowhere near the capacity provided by our VPS1 account. We are well below the maximum HD space and monthly allowable bandwidth. The site uses only standard HTML, text include files, and GIF/JPG graphics files; no streaming. There is only limited use of a CGI script for routine form submissions, and currently there are no PHP scripts running for BBs, calendars, blogs, chat rooms, or any MySQL databases being used. In short, I would think that the site places little load on the server or its processes.
I would greatly appreciate any feedback.

(Note that our real host name has been replaced above with "xxxxxx" to prevent possible spamming.)
I would appreciate any comments from experienced VPS customers or technicians, as to whether these incidences are considered normal with all VPS accounts, or if they might be indicative of a more severe problem with our web host's (Liquid Web) server.
As I mentioned on 11/29/07, "I use cPanel in my web browser to administer the site from a Macintosh computer running OS 9.2.2. I have never used SSH, and have also never read any raw logs. If I did, I'm not sure what they would tell me about this, anyway."
In the course of reading a number of posts in another WHT thread, there seems to be little agreement on the possible causes. Some have suggested that (1.) there may be "no space left on the device"; (2.) we may be "out of Semaphores" (I have no idea what those are!); (3.) we may be "out of RAM"; (4.) "/tmp is full"; or that (5.) "something is wrong with /tmp permission."
When I inquired in 2006 to Liquid Web's technical support about these recurrent failures, I was told that they are normal with this sort of hosting account. We pay them a hosting fee with the expectation of receiving an accurate diagnosis, but it would be very helpful to receive some impartial, third-party input.
I'm not sure if this is the right forum, or if anyone can suggest a message board where I might get support on this.
This is what I have. I have Apache and IIS both running on Windows 2k3.
Apache is running in reverse Proxy mode sending multiple domains/virtual hosts to IIS.
Code:
ProxyRequests Off <VirtualHost *:80> ProxyPreserveHost On ProxyPass / http://localhost:8080 ProxyPassReverse / [url] ServerName mydomain.com
</VirtualHost> Now, if I type in [url]everything works great and IIS (listening on 127.0.0.1:8080) serves the page. However, I am doing custom error trapping, so when I type in [url](and /mydirectory doesn't exist on IIS) I need to fire ASP code (via custom error messages/handling) on the IIS server and then present a data driven page.
However, Apache is returning A 502 error:
Code: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /mydirectory.
Reason: DNS lookup failure for: localhost:8080mydirectory Is there a way for me to setup Apache to pass all error checking to IIS while using it as a reverse proxy?
So I have a script running on my apache that catalogs pictures and clips. All the actual video files are located on a separate drive which is mounted in to a folder in my site. I've set apache as the owner and have the correct permissions on the mounted folder but I'm getting Forbidden errors accessing files even when on html file in the mounted folder.
I know it's a permissions issue at the disk or mounting level. The way I mount is by using this command:
i have made my all pages with .html extension and hence my SEO is based on accordingly. Now i made some changes to htaccess that causes to not inclusion of header and footer pages (both are made with .php extension ). so i decided to change the extension of pages (.html to .php) and it wokrs. due to SEO and large number of pages i want all my pages .php (made later). to get converted automatically with .html in browser. so is it possible using .htaccess rewrite.
how i can enable apache status like cPanel ! in directadmin
before im enabled
Location /httpd-status> SetHandler server-status </Location> but seems its not like cPanel ( dont show IP and where file now downloaded ... and more information)
