Issues with Apache+Nginx

[Oldiesmann]

After reading up on how using Nginx to serve static content can improve memory usage, site load times, etc., I decided to set it up on my VPS, and used the tutorial at http://www.whmsecurity.com/unixlinux-security/how-to-install-nginx-with-cpanel-apache-in-proxy-mode/ (only I used more recent versions of Nginx and PCRE). For the most part, it worked well - sites seemed to load faster and I was able to set things up within 30 minutes with very little downtime.

However, after generating the vhost.conf file and uncommenting things as per that tutorial, I ran into some weird issues:
It couldn't find the images and CSS files for the Citiez theme at http://cincymoves.oldiesmann.us (trying to access those files resulted in a 404 Not Found error)
The Curve theme on that site worked pretty well, but there was a weird gap at the top and it generated a 404 error for the facebook.png image in that theme as well

Thumbnails for the gallery on my Archie site stopped working (though this might be due to the fact that the images themselves are outside of public_html, but I didn't try experimenting to see if changing the root from /home/archie/public_html to /home/archie would fix that)

I also had some theme issues with my SMF test board.

Due to the problems, I've commented out the parts to make it server static images for now, but I would like to get this working. Does anyone have any suggestions?

Try having a go at my primer: http://blog.martinfjordvald.com/2010/07/nginx-primer/

If that doesn't help you out then please provide your the relevant vhost config and relevant error_log entries.

I think I have it figured out now actually. It was setting the root directories for the subdomains to /home/user/public_html instead of /home/user/public_html/subdomain. If I fix the roots for those, it works fine.

However, I do have one other issue I need to work out before I can enable this.

For ages, I've had the gallery set to rewrite URLs to download images:

Code Select Expand

    RewriteCond %{THE_REQUEST} /d/([0-9]+)-([0-9]+)/([^/?]+)(\?.|\ .)
    RewriteCond %{REQUEST_URI} !/index\.php$
    RewriteRule .   /gallery/main.php?g2_view=core.DownloadItem&g2_itemId=%1&g2_serialNumber=%2&g2_fileName=%3   [QSA,L]

If it weren't for the fact that it would cause problems with images previously posted on the forum, I'd just disable that particular rule from the Gallery2 admin area, but I don't want to do that.

How do I get Nginx to handle that rule?

I can also run a MySQL query to replace all the old URLs with the longer ones, but that's a bit of a pain and I'm not good with regex so I'd rather not do that if I don't have to.

[Something like that]

In the location block (or server block if none), add:

Code Select Expand


rewrite ^/d/([0-9]+)-([0-9]+)/([^/?]+)(\?.|\ .) /gallery/main.php?g2_view=core.DownloadItem&g2_itemId=$1&g2_serialNumber=$2&g2_fileName=$3 last;


Ought to do it.

[Oldiesmann]

Thanks for the help Mark! I'll try it out and let you know if it works.

[Oldiesmann]

Seems to be working fine. Thanks again!

Seems to be working fine. Thanks again!

Isn't that easier than Apache, too?

I Nginx.

Oldiesmann, your archieboy20.jpg example worked fine for me.

Make sure to control-refresh the broken images to see if your browser has cached the 404 response (I know Chrome will do this).

[Oldiesmann]

Yeah, it's all working again now. I don't really know what happened with that. That's why I ended up deleting that post and marking this solved again.

[Oldiesmann]

Hate to bump an old topic, but I have a quick question relating to this. I see that PHP 5.3.6 was just released, and I'd like to upgrade to that version. Can I just update it through WHM like usual, or are there extra steps I need to take first?

[Something like that]

I can't guarantee it, but if you don't let the upgrade replace the config file, you should be fine.

[Oldiesmann]

Thanks for the info Mark. I'll see if there's a script I can run to upgrade PHP without touching Apache.

[Oldiesmann]

Hate to bump this again, but I'm having problems here. I just set this up on a new server, and can't get the rewrite rule to work at all.

I have tried putting it inside the server block, inside the "location /" block and inside the other location block, and no matter what I do, it won't work.

I've commented out the lines for the servers in question right now as I don't want to leave them with a broken gallery.

I also checked the vhost.conf file from the old server and it looks like I had given up on getting it to work there as well, as the location lines are commented out for the sites that have galleries.

[Something like that]

Can you give me example URL that aren't working, what they're supposed to be change to, and a copy of your entire server block?

[Oldiesmann]

I have the location blocks in these server blocks commented out at the moment, but here you go.

URL not working: http://www.archiefans.com/gallery/d/18285-2/untitled.JPG
What it should be changed to:  http://www.archiefans.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=18285&g2_serialNumber=2&g2_fileName=untitled.JPG

I think that's right anyway - I'm not entirely sure what the g2_serialNumber item is used for.

The original rewrite rules from .htaccess for this URL:

Code Select Expand

    RewriteCond %{THE_REQUEST} /d/([0-9]+)-([0-9]+)/([^/?]+)(\?.|\ .)
    RewriteCond %{REQUEST_URI} !/index\.php$
    RewriteRule .   /gallery/main.php?g2_view=core.DownloadItem&g2_itemId=%1&g2_serialNumber=%2&g2_fileName=%3   [QSA,L]

It doesn't work with the rule you gave me above, or with the rule from http://gallery.menalto.com/node/80981

Server block:
