wordpress subdirectory multisite setup can't get it to work

[yosefy]

i just can't managed to get it working
examples i have are here: https://www.nginx.com/resources/wiki/start/topics/recipes/wordpress/#rewrite-rules-for-multisite-using-subdirectories

but it just won't work for unit in no way and that is sad because we can't move half of our sites

something with rewrite rules on paths like /aaa/ , /bbb/ (permalinks type)

single site wordpress works great

may be you can help with working config?
i can do the testing

i think many people still use wordpress

thanks

Hi @yosefy thanks for reporting this to us. We are just released a very basic implementation of URI-Rewrite to Units Router with the last release.
See the documentation.
https://unit.nginx.org/configuration/#uri-rewrite

Please share the Unit Configuration you are using so far.

So basically what you are trying to do is running multiple WPs sites on a single Domain (foo.com) seperated by different directories like /a/ and /b/. The Hostname configured in WP will be https://foo.com/a/ or https://foo.com/b/? Am I getting this correct? I haven't tried that but will work on it over the weekend and let you know.

[yosefy]

Yes I am aware of uri rewrite still couldn't manage to make it work

waiting for you answer. it is kind of deal breaker as for now for all the multisite i have to install nginx. which removes the whole idea of one tool doing it all. thanks

btw problem not only with multisite, but also with site that has siteurl as mainsite/blog

and wordpress is installed at /blog

now rewrites for nginx work as expected but for unit i couldn't find working config

i guess it is part of same problem

thanks

more info:
request to /he/wp-admin/

so you can see that apache only overwrites SCRIPT_NAME and SCRIPT_FILENAME
while uri stays the same

but when we do rewrite in unit it rewrites URI and there is no option to only change script name (we can't use variables in this field).

because in wordpress there is no real file in /he/wp-admin/ but it needs to keep uri as it redirects by it to next stage
for example to /he/wp-login.php. otherwise we are redirected to /wp-login.php without site dir prefix

when proxy with apache i see next headers:

Hi, @yosefy
Sorry for the late reply, but could you share what you expect based on the above configuration?

1. What's the request URL?
2. What's the expected value for the specific option compared to the current value? For example:

$_SERVER["SCRIPT_FILENAME"]:
current: ?
expected: ?

And btw, nginx works well, right? What's the nginx's configuration?
Thanks.

[yosefy]

@hongzhidao

for nginx is like this https://www.nginx.com/resources/wiki/start/topics/recipes/wordpress/

current is is whatever you put in application config hardcoded

what we need is like this:

in fastcgi_params they use vars
so in default nginx install you get fastcgi_params:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REQUEST_SCHEME     $scheme;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

and in nginx config

        location ~ \.php$ {
                #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
                include fastcgi_params;
                fastcgi_intercept_errors on;
                fastcgi_pass php;
                #The following parameter can be also included in fastcgi_params file
                fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }

[yosefy]

please pay attention to nginx rewrite rules for multisite
https://www.nginx.com/resources/wiki/start/topics/recipes/wordpress/#rewrite-rules-for-multisite-using-subdirectories

thanks

BTW for now we moving all back to php-fpm because we have lots of multisites and we will have to wait for this to be implemented

[hongzhidao]

I still can't understand the question totally.
Which params in PHP are different between Unit and nginx after rewritten?
It would be great if you can show the current value that might be wrong and the expected value that is correct for you.

[yosefy]

i have multisite with subdirectory sites
lets say first wp-admin is in /test1/wp-admin/ and second at /test2/wp-admin/
and may be there are more and i don't know what prefix they will be

so as you see in apache in my example
$_SERVER["REQUEST_URI"] == /he/wp-admin/
$_SERVER["REDIRECT_URL"] == /he/wp-admin/
but
$_SERVER["SCRIPT_NAME"] == /wp-admin/index.php
$_SERVER["SCRIPT_FILENAME"] == /sites/sitename.com/public/wp-admin/index.php

so this: RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
doesn't change request_uri really but changes the SCRIPT_NAME

while in unit rewrite rewrites the uri

i have spent lots of hours trying to config it to work

if you can we can have short session so i will show you the problem

thanks

apache with multisite site .htaccess is :

# BEGIN WordPress Multisite
# Using subfolder network type: https://wordpress.org/documentation/article/htaccess/#multisite

RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

# END WordPress Multisite

while apache with single site config is :

# BEGIN WordPress

RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

in http conf there is only

    <FilesMatch \.php$>
         SetHandler "proxy:fcgi://127.0.0.1:9026"
    </FilesMatch>

[hongzhidao]

Here's my example to minimize the question.

conf.json

{
    "listeners": {
        "*:8080": {
            "pass": "routes"
        }
    },
    "routes": [
        {
            "action": {
                "rewrite": "/wp-admin/",
                "pass": "applications/app"
            }
        }
    ],
    "applications": {
        "app": {
            "type": "php",
            "root": "/tmp/scripts/"
        }
    }
}

/tmp/scripts/wp-admin/index.php

<?php
print($_SERVER['SCRIPT_FILENAME']);

test

> curl http://127.1:8080/he/wp-admin

/tmp/scripts/wp-admin/index.php

Is it the same as you expected? If it's not, what's your expected value?
Sorry I can't find the problem from nginx and apache configuration, It's better to discuss it based on Unit configuration.

[yosefy]

Can you please share the whole SERVER array? I need to see if it rewrites uri That was the problem for me
