Mixed Virtualhosts and IP hosts

Server NGINX
#1

Hello,

I have 2-3 IPs.

I would like 2 IPs to be IP based hosts, and the 3rd IP to host
my virtualhosted sites.

Currently I have setup each domain with it’s own config file
that is called into nginx.conf inside the http {} section.

The IP based hosts are working fine, but I would like to check if
I am doing things right for the virtual hosts.

Each virtual host looks like this:

server {
listen xxx.xxx.xxx.xxx;
server_name sub.domain.com www.sub.domain.com;
access_log /var/log/nginx/sub.domain.com.access.log main;

    location / {
            index   index.php index.html;
            root    /home/subdomain/public_html/images;
    }

}

So each virtualhost has the same IP.

Will this work ok ? or do all virtualhosts need to be in their
own http {} section ?

Thank you

i think you only need one http {} for each specific http “instance”

you can have hundreds of server {} blocks inside of http {} - based on
the Host: header will answer. i only have one http {} block for
hundreds of sites. if nginx is listening on all interfaces it will use
the same instance.

i do have a second http {} block for a mogilefs webdav server, only
because of the separate http configuration needed.

I never tried several http {} blocks, and I’m not sure that it will
work correctly.

You need the single http {} section with many server {} sections.
Inside server you may use any combinations of IPs, ports, and names,
they
should work as one may expect. If there are duplicates names on some IP,
nginx will warn you and ignore the duplicate.

really? works fine from my perspective - here’s my config. seems to work
great.

i thought that was the whole point, is you can have multiple services
as needed (http, imap or whatever, etc) - i guess i’d take any
optimization pointers, i’m always interested in simplifying
configurations and optimization!

You may use http and main sections in one configuraiton, but several http’s
are not intended by design. Probably they sould work, I will investigate.

I have found the case that will not work: in the following configuration
all requests to 80 port will go to one server only, despite the Host
header:

http {
server {
listen 80;
server_name one;
}
}

http {
server {
listen 80;
server_name two;
}
}

So several http{} sections are not supported configuration.

I am totally fine with just making an additional server {} block
instead of http {}

This is pretty much the only configuration option I’d want to change:
client_body_temp_path /var/mogdata/.tmp;

would this work? I guess the more I think about it I don’t care where
it puts the temp files… I just know that /var/mogdata/.tmp works
nicely for the mogilefs stuff.

       server {
                  access_log off;
                  listen 7500;
                  server_name localhost;
                  client_body_temp_path /var/mogdata/.tmp;
                  charset utf-8;
                  location / {
                          root /var/mogdata/;
                          dav_methods put delete mkcol copy move;
                          dav_access user:rw group:rw all:r;
                          create_full_put_path on;
                  }
       }

That makes sense, this seemed logical because it was a different port.
It does seem to work though, but server {} allows for a different port
anyway, so I think I don’t even need it.

seems to work well - just took out that second http {} block and put
it in the first one and it seems to be functional still for mogilefs.

cool!

Yes, you may set/override client_body_temp_path on http/server/locaiton
level.

#12

That’s basically what I’ve done with the nginx config for
mogilefs, only a little different:

http {
…
server {
listen 7500;
server_name localhost;

     charset utf-8;

     location /dev1 {
         root   /var/mogdata;
         client_body_temp_path /var/mogdata/dev1;
         dav_methods put delete mkcol copy move;
         dav_access user:rw group:rw all:r;
     }

     location /dev2 {
         root   /var/mogdata;
         client_body_temp_path /var/mogdata/dev2;
         dav_methods put delete mkcol copy move;
         dav_access user:rw group:rw all:r;
     }
  }

}

  Each /dev is actually a dedicated disk with the same name.

Doing it that way lets you load up a box or add disks at will. Not to
go way off topic on mogilefs.

i only have one device on those servers.

however, i do have

    location /dev4 {
        root /var/mogdata/;
        client_body_temp_path /var/mogdata/dev4/.tmp;
        dav_methods put delete mkcol copy move;
        dav_access user:rw group:rw all:r;
        # not sure if this is needed
        create_full_put_path on;
    }
    location /dev5 {
        root /var/mogdata/;
        client_body_temp_path /var/mogdata/dev5/.tmp;
        dav_methods put delete mkcol copy move;
        dav_access user:rw group:rw all:r;
        # not sure if this is needed
        create_full_put_path on;
    }

on a server that does have two devices.

and i guess i answered a previous question - you could use a different
client_body_temp_path. funny how i already figured that out in the
last and forgot it :slight_smile: (igor already told me a second time, but
apparently i had it figured out on my own)

so according to your config you don’t have the “create_full_put_path”
and it still works like a charm? i am not using mine in production
yet, i assume you are…

#14

I did that example off the top of my head, but yes I do have
create_full_put_path enabled, it was more an example of using location
to enable the use of multiple devices in a config. The
client_body_temp_path is important if each location is at a separate
physical mount point otherwise you’ll run into nginx not writing data.

okay. cool. i’m going to remove my comment that says “might not need
this” then :slight_smile:

#16

Thanks for your replies guys. Will start transferring the domains and
see how it
goes :slight_smile:
