I have set up a virtual server with a LAMP stack (Centos 6.3) and am now trying to install nginx to use as a proxy server. I have been told to download from sudo rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-r... and have done so prior to trying to install nginx. However, something was wrong with this because when I tried to install nginx (sudo yum install nginx), there were a number of packages that were skipped due to dependency problems. When I tried to start nginx, it could not find the files. Given that nginx is a well-used server, this has to be easier than what I am encountering. Does anyone know the correct commands to set this up so that nginx can install? Thanks. Posted at Nginx Forum: http://forum.nginx.org/read.php?2,236254,236254#msg-236254

If you're going to install nginx from a repo, why not use theirs? rpm -Uvh http://nginx.org/packages/centos/6/noarch/RPMS/ngi... then yum install nginx ( next question... why only use it as a proxy server? ) Steve

Thanks for the suggestion, Steve. I was working from that angle before based on advice from a person at my hosting company and had used the nginx repo. I am addressing three points in response. Any suggestions/thoughts from you and/or others are appreciated. (1) Reason for nginx and apache: The reason I am planning to use nginx on the front end and apache on the back end (instead of nginx for all of it) is that I've read in an article that apache’s power and nginx’s speed are well known. But apache is hard on server memory, and nginx (while great at static files) needs the help of php-fpm or similar modules for dynamic content. The article goes on to recommend that you combine the two web servers, with nginx as static web server front and apache processing the back end. My application has a lot of dynamic content including videos, and makes use of ajax and jquery. What are your and others thoughts on the nginx / apache / both question? (2) Your command to get the nginx repo: when I tried this again with your specific command, I got: [m@01 ~]$ rpm -Uvh http://nqinx.org/packages/centos/6/noarch/RPMS/ngi... Retrieving http://nqinx.org/packages/centos/6/noarch/RPMS/ngi... curl: (6) Couldn't resolve host 'nqinx.org' error: skipping http://nqinx.org/packages/centos/6/noarch/RPMS/ngi... - transfer failed (3) Past attempt at installing nginx in a similar way: I'm pasting the output from this past attempt in case anyone can see what might be missing or wrong...

Installing as root allowed the method under (3) to work. Still have a problem starting nginx, but I'll see if I can work thru that. I would appreciate comments on item (1) though from anyone's experience. Thanks. Posted at Nginx Forum: http://forum.nginx.org/read.php?2,236254,236263#msg-236263

what was the article that you read? you should probably do your own tests to work out the fastest way to do it if you really need as many dynamic requests as possible My thoughts at this point (after using nginx for 3+ years) is that I would avoid using apache - KISS!
on 2013-02-17 15:26
Here's the article: https://www.digitalocean.com/community/articles/ho... I agree that if I could do it all with one web server, it would be simpler/cleaner. I'm just not sure based on what is in this article that nginx will be fine alone - "nginx (great at static files) needs the help of php-fpm or similar modules for dynamic content".

Hi Many (MANY) people use php-fpm and it's fine If you really need extra performance you should test it yourself on your own application (not hard to do) and see if proxying to apache actually gives any benefit

It looks like PHP-FPM comes with PHP 5.3.3, so I should have it already for use with nginx. Thanks. Posted at Nginx Forum: http://forum.nginx.org/read.php?2,236254,236268#msg-236268

I use nginx and PHP-fpm without any problems.

You need to use sudo for this as well. After fixing this, you'll be installing 1.2.7, not 0.8.

Thanks for catching that type, GreenGecko. I was able to get nginx installed, but at this point it won't start (bind, that is). Is this problem familiar to anyone? >>> the end of the installation... Installed: nginx.x86_64 0:1.2.7-1.el6.ngx Complete! >>> trying to start nginx... [root@01 ~]# /etc/init.d/nginx start Starting nginx: nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use) nginx: [emerg] still could not bind() [FAILED] Posted at Nginx Forum: http://forum.nginx.org/read.php?2,236254,236273#msg-236273

You've already got something running on port 80... either your old nginx, or apache. Error messages are there to help you... Steve
