Nginx installation guide for Debian Wheezy

techworld

Hi all,

I’m currently using Clonezilla, and would like to try out FOG.
However, I can’t find a installation guide for Nginx.
My server is currently running on Nginx, therefore, Apache 2 causing conflict for me.

Thanks in advance.

Wayne Workman

I’m told that FOG can run on Nginx but takes some doing to get it to work. I wouldn’t know what those doings are.

Can you not create a VM on this server and install FOG with it’s standard installer and use Apache, or simply provision another server?

I don’t know that it’s specific to debian or not, but I do run nginx on my dev box simply because my box isn’t all that powerful and I need faster response for testing purposes.

My methods required a bit of configuration first.

My example layout:

Install nginx. This can be found anywhere, but most likely you can just run sudo apt-get install nginx

Ensure you have php-fpm module installed. sudo apt-get install php5-fpm

Configure FPM so nginx can access it: You will need to find the www.conf file for fpm.

For me it’s found under: /etc/php-fpm.d/www.conf I don’t know what it relates to in debian.

In this www.conf file look for the listen = line. It will likely be set to a socket, but I prefer to use tcp on port 9000. My config for this line reads: listen = 127.0.0.1:9000

Save the file and start php-fpm service. (sudo service php5-fpm restart).

Next comes nginx config. My config location is at /etc/nginx/conf.d

In this folder I created a file called fog.conf.

Contents of this file are:

server {
    #Normal web port
    listen 80;
    #SSL Web port
    listen 443 ssl;
    #Where to get the cert -- I have secure setup on my side
    ssl_certificate /path/to/ssl/file.crt;
    #Where to get the key
    ssl_certificate_key /path/to/ssl/file.key;
    #This is important will post copy after this
    include conf.d/*.loc;
    server_name somenameifneeded.com;
    #This sets the web root path for me I don't need /fog trailing.
    root /path/to/web/fog;
    #This enables auto loading of index.php if requested to the root file instead of index.php
    index index.php index.html index.htm;
    #Self explanatory
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    #Turn on my ciphers
    ssl_prefer_server_ciphers on;
    #How to diffie helman information
    ssl_dhparam /path/to/ssl/dhparams.pem;
    #My cipher list (pretty strong I think)
    ssl_cipher 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA';
    #SSL Session times out in one day
    ssl_session_timeout 1d;
    #SSL Cache getter.
    ssl_session_cache shared:SSL:50m;
    #More header to ensure security
    add_header Strict-Transport-Security max-age=15768000;
}

The *.loc from earlier:
You might have other .locs so adjust as needed. For me I only have a file called php.loc
This is the important bit as it is how it handles php.
It contains:

location ~ \.php$ {
    # Zero-day exploit defense.
    try_files $url =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    include fastcgi_params;
    fastcgi_index index.php
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_pass 127.0.0.1:9000;
}

That’s about it I think. Of course you will need to find your stuff. But this should help you along the way.

Also, please restart the nginx service so all these things can take affect.

When this is running, errors are not written to /var/log/httpd or /var/log/apache2. Some errors will be in /var/log/nginx but most relevant bits is found in /var/log/php-fpm/www-error.log

sudo service nginx restart

Hi,

I’d set up a few webserver, if you guys can point in me the direction, I think I can set it up.
If I successfully set it up, I would post my result here.

In the mean time, we’re getting somewhere here.
I don’t have /etc/php-fpm.d/www.conf in my server.
It has these: /etc/php5/fpm$ ls -la total 84 drwxr-xr-x 3 root root 4096 Jun 29 18:19 . drwxr-xr-x 8 root root 4096 Jun 30 19:05 .. lrwxrwxrwx 1 root root 9 Mar 11 19:23 conf.d -> ../conf.d -rw-r--r-- 1 root root 4555 May 22 2015 php-fpm.conf -rw-r--r-- 1 root root 64378 Jun 16 18:12 php.ini drwxr-xr-x 2 root root 4096 Aug 19 13:35 pool.d

My question is when I follow the instruction, Apache2 is install automatically.
How do I avoid that?

After FOG is installed, open /opt/fog/.fogsettings and remove apache2 from the packages list, save and close. It will then - on next update/reinstall - not install apache.

However, there are other problems too. The fog installer tries to configure and restart apache. You’ll probably need to just comment those lines out.

I think I found the php-fpm setting for Nginx:

upstream php-handler {
    server 127.0.0.1:9000;
    #server unix:/var/run/php5-fpm.sock;

So there is no other way to avoid Apache2 install prior to the installion?
I don’t want Apache2 mess it up with my Nginx.
I tried earlier today, and it screw me up.

Another thing I notice that since we save (upload) images to the server, we need to define the client max size too, right?
Maybe like this ?

client_max_body_size 20m;
client_body_buffer_size 128k;```

@techworld I also run my dev servers on nginx. Here is my upgrade-fog.sh script for CentOS:

#!/bin/bash
echo
echo ===========================================================
echo Stopping nginx
echo ===========================================================
echo

systemctl stop nginx

echo
echo ===========================================================
echo Upgrading FOG
echo ==========================================================
echo

cd /opt/fogproject
git pull
cd /opt/fogproject/bin
./installfog.sh -y

echo
echo ===========================================================
echo Reconfiguring Web Server
echo ===========================================================
echo

systemctl stop httpd
systemctl disable httpd
systemctl start nginx

echo

As you can see I leave apache (httpd) installed, but I just disable the service. As for uploading images, that is done through NFS, and not http(s) (nginx).

And the nginx configuration Tom posted is exactly what you should be using. We (and some google fu) made it together when porting our servers to nginx and it works flawlessly for us.

@Joe-Schmitt
Hi,
I’m not concern about the upgrade process right now.
Do I follow Wayne’s guide to remove Apache2 after the installation in order for Nginx to work?

Joe Schmitt

Just follow the end of my upgrade script (obviously you will need to alter it for Debian). Simply stop and disable Apache, there is no need to uninstall it.

techworld

I installed FOG again, and same issue happened.

/opt/fog/.fogsettings is nowhere to be found.
Can’t find the proper file to stop apache2.
