Server :: Tuning Apache To Handle PHP With NginX On The Frontend

Jun 24, 2010

My intention is to have EngineX on the frontend handling all static files, and Apache + mod_php in charge of handling PHP requests. I have optimized nginx to be as efficient as possible in handling static files, but have very little experience with Apache. Since Apache would only be processing PHP requests, would the standard Apache optimization guides suffice or would it best to configure it differently?

PS: this is a dedicated file server, the database is hosted separately.

Server :: Server Slow : Apache Mysql Fine Tuning Server For Faster And More Responsive?

Apr 21, 2011

I'm running a linux cloud server with the following config
1.2ghz Processor allocation
752MB Ram

The site loads slow and clicking a link almost freezes the page for a second. Also, the page loads could be much faster. We've been running mysqltuner and have pretty much optimized all slow queries. Is there anything we can do to fine tune the server for faster and more responsive?


Timeout 20
KeepAlive Off
MaxKeepAliveRequests 100

Server :: Apache Maxclient / Serverlimit Perf Tuning?

Mar 25, 2010

I've been trying to set-up/tweek these param's in Apache to a setting suitable to the server for the amount of memory. When i look around some people say, hey.. just look at the memory used per process and then divide that by the amount of memory available and you get the number of processes that can be handled by Apache in one go before it starts swapping.

Well, for this i'd done this calculation and for me it turned out to be 200 approx concurrent connections. Well funny thing is, out MySQL server had a slow down so the Apache servers were running at approx 450 concurrent connections and weren't swapping in memory etc (still had 600MB free not including what was available in Buffers/Cache - 'free -m')... Thus if i had have set the limits to 200 then people would have been not getting to the site, so i'm kind of pleased that i happened to not have the time to set this yet.

Server :: How To Force Nginx To Do DNS Lookups

Jun 2, 2011

way to get nginx to perform DNS lookups at regular intervals against hostnames that are defined for upstream servers? It seems nginx only performs a DNS lookup once, the first time it starts, and subsequently does not perform any other DNS lookups. This causes problems when the ip addresses of our upstream servers change.

I posted this same question in the nginx forum; however I also posted it here as it seems that not many of the posts there get answered.

- nginx will listen on port 80
- requests for => Domino HTTP server (on different server)
- if this server is not reachable, go to another Domino HTTP server

Networking :: Tuning For High Throughput Reverse-proxy Server?

Jan 18, 2011

I have an enormous quadcore machine with 16gb ram and dual gigabit NICs. It used to be for MySQL but we have upgraded the whole database infrastructure so now this server is left floating. I had the great idea of turning this into a reverse-proxy (using apache mod_proxy) and it really handles a ton of requests. But I have a feeling that we are not getting the most use out of what it can offer.

Our traffic consists of a few thousand very small (less than 10 byte) ajax calls per second, and frequently I find we are running out of kernel allocated network stack to handle all the requests. Often we get the kern.log warning "possible SYN flooding on port 80. Sending cookies." and other things like this. Obviously we are not getting SYN flooded, we just have very high demand.

So far I have found a few kernel tuning guides to tell the kernel to allocate more of the base system memory for networking but every guide I have found has been for the purpose of increasing the performance between WAN links (direct backbones between offices etc) and usually with very large file sizes being the priority. One such example (and great) write up is here:

I was hoping some people could provide further input, such as along the lines of disabling nf_conntrack (to speed up socket set up/tear down time) or anything that will speed up a high throughput proxy like mine. Any links to studies or benchmarks between different configurations or hardware gets extra points!

Server :: Config NGINX For Multiple Domains With Wordpress On Debian?

I have VPS installed with Debian, NGINX, mysql, php and wordpress. By default the template gives 1 wordpress install in the /var/www/ directory. However, now I want to add more domains with wordpress to that VPS. I created a directory called /home/public_html/ and linked it to the /var/www/ directory. then I created another directory called /home/public_html/ and uploaded wordpress there. What I did next was edit my /etc/nginx/nginx.conf file with the following code:

Server :: Nginx/php/spawn-fcgi: No Response When Script Requests Same

Apr 12, 2011

I have a perfectly working installation of nginx / PHP / fastcgi on the latest stable Debian distribution. No problems at all, apart from this one: When a PHP script (script A) is written to request a PHP script on the same web server (script B), nginx takes several minutes to respond and finally the connection times out. And it happens only when invoking script A through nginx. Calling it from command line works fine � I get a normal output of script B.

Literally, the test case is as simple as:

Script A:

PHP Code:


I suppose the root of the problem may be some obstacle occurring when php5-cgi ends up invoking itself. And this is what happens when script A is called through nginx. But I have no ideas yet how to address the problem. One of my PHP applications checks itself during installation, that's why I need to request a PHP script from a PHP script on the same server.

Server :: Nginx Virtual Hosts & Wordpress Rewrite Rules?

Sep 14, 2010

I'm trying to set up my web server (nginx) as a catchall virtual host, as per an example that can be seen here: [URL].. (It's the Wildcard Subdomains in a Parent Folder example). Now, here's my issue. I use Wordpress on the domain. I have pretty URLs enabled, that make my Wordpress articles look like this:[URL].. At the moment, nginx is reporting 500 Errors, saying that index.php is not a directory. What I want to do is make a rewrite rule that allows me to use the above URL example with nginx.

I followed this tutorial to do so: [URl].. , but I'm not sure how to apply it to my setup. Here's my configuration files from Debian Squeeze with Nginx onboard:

Server :: Tunnel Apache Virtual Host To An Internal Apache?

Jan 24, 2010

I am upgrading my server and I have a lot of sites. Since I cannot take my server down for a few days, maybe a week until I manage to migrate all the sites to the new machine, I figured I could migrate them one by one. After migrating one, I would somehow tunnel the requests of that name virtual host to my internal machine. When everything is migrated, I would then switch the machines, update ip's and stuff and everything will work just fine.

However I cannot seem to find a way to do this tunneling. is this at all possible? If not, what alternatives do I have?

Server :: Configuring Sendmail To Handle Addresses But Not The Whole Domain?

Mar 22, 2011

From my main Postfix SMTP heads, I am sending just a couple select emails (primarily support emails) off to a server that receives them and pipes them into the support software. So far this totally works perfectly and I am pretty happy with the configuration. However, in order for sendmail on the support server to receive those emails I have to place them in the virtusertable of course, but I also have to activate their domain in the local-host-names file. That then causes sendmail to consider itself as the destination server for that whole domain.Is there a way to make sendmail receive email for select addresses without making it think it's the server for the whole domain? This server is only receiving email from two specific smtp servers, so I wonder if I could just permit relaying? Wonder if that would just cause a giant loop though.
