Dear everyone i'm first timer here

I used to installing older moodle with nginx (maybe version 3.6 or something)

today i need to install new moodle 3.10 instance with nginx and i get error 404 with something likes

"http://ipaddress/admin/<a></a>" in address bar

First part of installation was fine with php extension check up all green, upgrading plugin all succeed until 404 jumping at me.

How exactly did you install? Have you checked folder permissions on the new code? Deleted cache and localcache folders from your moodleDATA folder (NOT the code folder).?

1. This is new installation without old code base.
2. I might try looking at code folder permission. What's correct permission for code folder?
3. i already cleared cache from data folder.

I normally set mine at 755 but you also need to make sure www-data or apache is the owner...depending on your os

I must say it still not working 悲しい after doing chmod, chown.
I just wonder how can "<a></a>"  get in url redirect likes "http://ip/admin/<a></a>"?

Can you load the site with developer tools open (Chrome or Firefox, F12), and screenshot the network tab when you load the site.

Further, immediately after you encounter the issue, take a look at the nginx error logs using the below commands and copy/paste anything that looks unusual here.

sudo tail /var/log/nginx/error.log
sudo tail /var/log/nginx/access.log

Ensure you have index.php listed within the 'index' directive in your nginx configuration, reload nginx (sudo service nginx reload), and then issue sudo chmod -R 755 /var/www/moodle

Are you trying to install Moodle alongside other non-core plugins at the same time? I am a bit confused as to why you need to upgrade plugins.

Download the latest release (Moodle 3.10.1+) and do not add any other plugins. There should be no need to install other plugins when you first install Moodle - you can add them later - ideally individually. The best way to accomplish this is through git.

sudo apt install git
sudo chown -R $USER:$USER /var/www
sudo chmod -R 755 /var/www
cd /var/www
git clone git://git.moodle.org/moodle.git
cd moodle
git branch --track MOODLE_310_STABLE origin/MOODLE_310_STABLE
git checkout MOODLE_310_STABLE

Alternatively, get from here: https://download.moodle.org/releases/latest/

You can also run the installer on the command line. I must confess I am a bit unfamiliar with the web installer because I don't use it. 

sudo chown -R $USER:$USER /var/www
sudo chmod -R 755 /var/www
sudo mkdir -p /var/moodledata
sudo chown -R $USER:$USER /var/moodledata
sudo chmod -R 777 /var/moodledata
rm -rf /var/moodledata/*
php /var/www/moodle/admin/cli/install.php

If you do elect to use the web installer again, you will instead want:

sudo chown -R www-data:www-data /var/www
sudo chmod -R 755 /var/www

I must say I am quite confused.

Can you please try clearing your browser cache and visiting admin/index.php directly. Also try incognito mode with no browser extensions. Disable any antivirus web filtering too.

That PHP version is fine.

By nginx guy - do you mean to say someone else manages nginx for you? Or are you paying nginx for support?

There's a chance other nginx configuration is interfering with Moodle.

I'm at a dead end diagnosing this. The only thing I can offer you is that you can zip your full nginx configuration and code directory (including config.php) and send it to me using the email address on my profile here. I will try installing it on a fresh Ubuntu 20.04 VM.

Do not include any confidential information if you do this.

I have received your nginx configuration and wwwroot by email.

I'm still looking at it, but one obvious issue that jumps out at me is that you haven't defined an index page in your nginx server block. Add a line as follows and reload nginx.

I installed Moodle with your nginx configuration, and wwwdata, following your configuration almost exactly.

I noticed that you did add an index directive within the http block in nginx.conf, so that is not the issue. The install ran fine. I did not encounter is a redirect to <a></a>. I have absolutely no idea what is causing that.

I suggest using a different PC to install Moodle and starting with a fresh Ubuntu 20.04 server install.

This thread appears to be mostly about config of nginx.   If you do a curl -I https://yoursite/ the response shows you are running:

Server: Apache/2.4.46 () OpenSSL/1.0.2k-fips
X-Powered-By: PHP/7.4.15

OpenSSL/1.0.2k-fips usually indicates a RedHat Family OS ... CentOS?

The last step in install is to set up admin user.   Did you get that far?

Also ... .htaccess???!!!  what for?   trying a redirect to get to the admin user setup?

This issue can be caused by an invalid character being present in the site URL. Can you check your site URL in config.php and make sure it is properly encoded, and does not contain, for example, a space or an invisible character.

Try deleting the entire $CFG->wwwroot line in config.php, and add a new line, and type it into the text editor rather than copying and pasting it.
