Aley's questions

I would like to set the variable $sub conditionally dependent on $request_uri and $host.

map $request_uri $sub {
    default       front;
    ~^/api/.*     api;
    ~^/rest/.*    rest;
}

map $host $sub {
    hostnames;

    #default    $sub; # Tried, no success

    ping.*     ping;
    admin.*    admin;
}

server {
    listen 80;
    server_name _;

    root /usr/share/nginx/html;

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_param HTTP_X_SUB $sub;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
    }

    location / {
        try_files $uri $uri/ /index.php;;
    }
}

I thought nginx will not overwrite $sub in map $host $sub if the hostname is not in the list, but unfortunatly it just blanks out $sub.

So basically it should be like if $host is "ping" or "admin" set $sub accordingly. If hostname did not match, check for $request_uri.

Any idea how to archive that statement?

EDIT: Extended the config.

My request looks like this

domain.com/lib/browser/detect.js

Now internally I would like to serve /lib/browser/detect.php

My Nginx conf looks like this

location = /lib/browser/detect.js {
        try_files non-existent /lib/browser/detect.php;
}

location ~ \.php$ {
        fastcgi_split_path_info ^(.+?\.php)(/.*);
        fastcgi_read_timeout 900s;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        include /etc/nginx/fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

Nginx forces my browser to download this file.

I have the following site configuration

<Location />
    AuthUserFile /path/.htpasswd
    AuthName "Restricted Area"
    AuthType Basic
    require valid-user
</Location>

which restricts access to all locations. Now I want to exclude say media/

<Location /media>
    Require all granted
</Location>

and also upload/ which is in another directory

Alias /upload/files/ /another/path/upload/files/
<Directory "/another/path/upload/files/">
    Options None
    AllowOverride None
    ForceType text/plain

    Require all granted
</Directory>

Unfortunately it still prompts me for authentication.

I'm trying to Proxy Pass /do/uploads.php?id=xxx to /do/upload?id=xxx in Nginx

Here is my try

location /do {
    rewrite /do/uploads\.php /do/uploads$1 break;
    proxy_pass          http://domain/do;
    proxy_set_header    Host $host;
    proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header    X-Forwarded-Proto $scheme;
    proxy_set_header    X-Real-IP $remote_addr;
}

I have an AngularJS app in /home/app/front and a PHP backend in /home/app/back. Now I would like to serve static files from / and PHP from /api/v1/

I tried the following config with no success. Nginx throws the following error message: FastCGI sent in stderr: "Primary script unknown"

server {
    listen 80;

    server_name localhost;

    location / {
        root /usr/share/nginx/html/wpplugins/frontend;
        try_files $uri $uri/ /index.html;
    }

    location ^~ /api/v1/ {
        root /usr/share/nginx/html/wpplugins/backend;
        try_files $uri $uri/ /index.php?_url=$request_uri;
    }

    location ~ \.php {
        fastcgi_index /index.php;
        fastcgi_pass unix:/var/run/php5-fpm.sock;

        include /etc/nginx/fastcgi_params;

        fastcgi_split_path_info       ^(.+\.php)(/.+)$;
        fastcgi_param PATH_INFO       $fastcgi_path_info;
        fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

I have the following hostname structure:

main.domain.com is the main subdomain and is static; any other subdomain is dynamic *.domain.com

The root directory is the same for all hostnames.

Now what happens: When I access fruit.domain.com its redirecting me to main.domain.com, but it should actually stay on fruit.domain.com.

My configs:

server {
    listen 80;
    listen [::]:80;

    server_name main.domain.com *.domain.com;

    return 301 https://$server_name$request_uri;
}

server {
    listen 443 default_server ssl spdy;

    server_name main.domain.com *.domain.com;

    root /home/www/app
    ...
}

I want to have phpMyAdmin running under another port and pass all requests that go to /pma/ to 127.0.0.1:8081

Thats my Nginx config

server {
   listen 80;
   ...
   location /pma/ {
       proxy_pass        http://127.0.0.1:8081/;
       proxy_redirect    off;
       proxy_set_header  Host $host;
   }

   location ~ \.php$ {
       ...
   }
}

Now when I request http://domain.com/pma/phpinfo.php location ~ \.php$ takes over the control and I get a 404. Is it possible to always pass the request to http://127.0.0.1:8081 when its to /pma/?

I have a WordPress installed in /var/www/wordpress/ and my own code in /var/www/project/

Now comes the following problem: When I try to access example.com/client/ or example.com/admin/ it should link to /var/www/project/ and execute the .htaccess + index.php from there.

I have tried to place an Alias directive in the Apache config with partial success.

Alias /admin/ /var/www/project
Alias /client/ /var/www/project

When I access example.com/client/ it works fine, but as soon as I request example.com/client/login it failes with File does not exist: /var/www/project/login error.

The .htaccess in /var/www/project looks like

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/(.*)$ index.php?module=$1&task=$2 [L,QSA]

I've installed Nginx using apt-get install nginx but now I need to add SPDY and PageSpeed extensions. This is why I need to remove the current Nginx installation and install the new one from source.

How should I proceed? Do I have to uninstall the current Nginx and then compile the new one to avoid complications between those two?

How do I register the custom Nginx as a service so I can use service nginx start and make it start on boot?

What I have tried ...

# apt-get install php5-dev
# apt-get install gearman-job-server libgearman-dev
# pecl install gearman

Result ...

...
configure: error: Please install libgearman
ERROR: `/tmp/pear/temp/gearman/configure' failed

Than I tried ...

# export GEARMAN_LIB_DIR=/usr/include/libgearman
# export GEARMAN_INC_DIR=/usr/include/libgearman
# pecl install gearman

Result ...

...
configure: error: libgearman version 0.21 or later required

Then I tried ...

# wget pecl.php.net/get/gearman-1.1.1.tgz
# tar -zxf gearman-1.1.1.tgz
# cd gearman-1.1.1
# phpize

Result ... same error as in attempt 2

Whats wrong?
