nginx sub location with php-fpm config failed - php

Question

I have an nginx config for my server as follow, I want
when I request service/dev/sync/sync
it will route to /home/work/app-web/src/api/dev/sync.php/sync
match the php rule with $fastcgi_script_name is /dev/sync.php and $fastcgi_path_info is sync
this rule only need for ~ /service/([a-zA-Z]*/[a-zA-Z]*)(/[a-zA-Z]*)$.
But when I request /service/dev/sync/sync, it will return 404 with error
*173 open() "/home/work/nginx/html/dev/sync.php/sync" failed (2: No such file or directory), client: 172.18.17.90, server: localhost, request: "POST /service/dev/sync/sync HTTP/1.1"
/home/work/nginx/html is the default root for my nginx server. the root config is not
work at all.
what's the problem with this config?
server {
set $work_dir /home/work/app-web;
listen 80;
server_name localhost;
location ~ /service/([a-zA-Z]*/[a-zA-Z]*)(/[a-zA-Z]*)$ {
root $work_dir/src/api;
set $file $1;
set $action $2;
try_files $uri $uri/ /$file.php$action$is_args$query_string;
location ~ \.php {
fastcgi_split_path_info ^(.+\.php)/(.*)$;
fastcgi_pass unix:/home/work/app-web/php/var/run/app-web.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $work_dir/src/api$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param UNIQUE_ID $request_id;
include fastcgi_params;
}
}
}

Root config works fine.
Your problem is that there is an internal redirection to /dev/sync.php/sync?, and the new inner-url does not match the regexp-location
You can activate the debug with
error_log /var/log/nginx/debug.log debug;
The logs look like this :
*1 trying to use file: "/dev/sync.php/sync" "/home/work/app-web/src/api/dev/sync.php/sync"
*1 internal redirect: "/dev/sync.php/sync?"
*1 rewrite phase: 1
*1 http script value: "/home/work/app-web"
*1 http script set $work_dir
*1 test location: ~ "/service/([a-zA-Z]*/[a-zA-Z]*)(/[a-zA-Z]*)$"
*1 using configuration ""
The new URL is /dev/sync.php/sync?, and this url matches with no location, because the regexp /service/([a-zA-Z]/[a-zA-Z])(/[a-zA-Z]*)$ is not intended for the inner-URL.
I suggest you another configuration :
server {
set $work_dir /home/work/app-web;
listen 80;
server_name localhost;
location ~ /service/([a-zA-Z]*/[a-zA-Z]*)(/[a-zA-Z]*)$ {
root $work_dir/src/api/;
set $file $1;
set $action $2;
rewrite .* /src/api/$file.php$action last;
}
location ~ \.php {
internal;
root $work_dir;
fastcgi_split_path_info ^(.+\.php)/(.*)$;
fastcgi_pass unix:/home/work/app-web/php/var/run/app-web.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param UNIQUE_ID $request_id;
include fastcgi_params;
}
error_log /var/log/nginx/test-error.log debug;
}
Note the internal; directive
