nginx try_files with $host - web-services

Question

In my configuration i use the host-name($host) as directory so i don't need to make a entry for each domain in the config (only for development purpose)
one issue is that try_files failed i tried different ways but all of them without success.
try_files html\$host$uri =404;
try_files $document_root\$host$uri =404;
try_files $uri =404;
try_files $document_root\$host$fastcgi_script_name =404;
server {
listen 80;
server_name default;
charset UTF-8;
#access_log logs/host.access.log main;
# redirect server error pages to the static pages
error_page 500 502 503 504 /error/50x.html;
error_page 404 = /error/404.html;
error_page 403 = /error/403.html;
location ^~ /error/ {
internal;
root html/default;
}
location / {
root html/$host;
index index.php index.html index.htm;
}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
#try_files html\$host$uri =404;
#try_files $document_root\$host$uri =404;
#try_files $uri =404;
#try_files $document_root\$host$fastcgi_script_name =404;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root\$host$fastcgi_script_name;
include fastcgi_params;
}

Answer 1

The concept it self is correct, but you are applying it in the wrong place, you should place this as a root for the server, not in the try_files
Also I believe you should use $http_host not $host, refer to this answer to know the difference
I don't know why your paths are not absolute, they should start with /
I'll add changes to your current posted config
server {
#since you will match multiple domains I removed the server_name
listen 80 default_server;
charset UTF-8; # don't really need this but it won't hurt.
root /usr/share/nginx/html/$http_host; #assuming this path
index index.php index.html index.htm;
# redirect server error pages to the static pages
error_page 500 502 503 504 /error/50x.html;
error_page 404 = /error/404.html;
error_page 403 = /error/403.html;
location ^~ /error/ {
internal;
root /usr/share/nginx/html/default;
}
location / {
try_files $uri $uri/ /index.php$is_args$query_string;
}
location ~ \.php$ {
# these are the minimal required parameters.
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
}
}
