HTTP ERROR 500 after making changes in Nginx and MariaDB

Darkle

Hi! I've been making some changes in a server with several Flarum installations, after doing so one of the Flarum sites failed (the rest works). It's the first time that something like this happens to me, I don't know what logs I should send so that someone can help me, I attach the only flarum log (note that when the error occurred this log didn't exist until some time later):

[2021-03-08 21:49:39] flarum.ERROR: Symfony\Component\Console\Exception\CommandNotFoundException: Command "install" is not defined. in /var/www/flarum/vendor/symfony/consol$ Stack trace: #0 /var/www/flarum/vendor/symfony/console/Application.php(237): Symfony\Component\Console\Application->find('install') #1 /var/www/flarum/vendor/symfony/console/Application.php(149): Symfony\Component\Console\Application->doRun(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfo$ #2 /var/www/flarum/vendor/flarum/core/src/Console/Server.php(42): Symfony\Component\Console\Application->run() #3 /var/www/flarum/flarum(24): Flarum\Console\Server->listen() #4 {main}

I really don't know what could be wrong, the fact that the other sites are working makes me rule out problems with Nginx or MariaDB... 🤔

Darkle not necessarily. Can you post your nginx.conf file for the site that isn't working ? I've seen this happen before with an invalid php-fpm sock file in nginx

Do you know what was being done at the time of the log? That error should only happen if you try running the php flarum install command via SSH while Flarum is already installed.

If there's a 500 error accessing the website but nothing in the logs, it could be a PHP error and not Flarum error. In that case it will be logged to the global system log file (apache error, nginx error, php error, something like that)

If there's still nothing, try enabling debug mode in Flarum (debug to true in config.php) and check file permissions on the log folder to make sure Flarum can write to it.

Darkle

clarkwinkelmann You are absolutely right, I mistakenly ran the php flarum install command and it matches the time.
I will take a look at those logs before continuing.

This is the log I found in /var/log/nginx/error.log. The same error is reproduced over and over again when I try to access the site. There are dozens if not more of them, I would say they are exactly the same, so I have put the most recent ones.

[deleted] It took a while without looking at the conf file of this site, this is the one I had originally and with which it worked, I think it has the redirection from www to non-www:

server {
listen 80;
server_name www.brickdose.com;
return 301 $scheme://brickdose.com$request_uri;
 }

server {

 server_name brickdose.com www.brickdose.com;
 root /var/www/flarum/public;

 index index.php;

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

 location ~* \.php$ {
   fastcgi_pass unix:/run/php-fpm/www.sock;
   include fastcgi_params;
    fastcgi_index index.php;
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }


listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/brickdose.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/brickdose.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
if ($host = brickdose.com) {
    return 301 https://$host$request_uri;
} # managed by Certbot


listen [::]:80;
listen 80;

server_name brickdose.com;
return 404; # managed by Certbot

}

And this other one is the one I have put now and it doesn't work either:

server {

server_name brickdose.com www.brickdose.com;
root /var/www/flarum/public;

index index.php;

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

location ~* \.php$ {
fastcgi_pass unix:/run/php-fpm/www.sock;
include fastcgi_params;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/www.brickdose.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/www.brickdose.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
 server {
    if ($host = brickdose.com) {
    return 301 https://$host$request_uri;
  } # managed by Certbot


if ($host = www.brickdose.com) {
    return 301 https://$host$request_uri;
} # managed by Certbot

 listen [::]:80;
 listen 80;

server_name brickdose.com www.brickdose.com;
return 404; # managed by Certbot
}

askvortsov

Darkle Looks like a permission error; make sure your webserver user has recursive ownership over the entire flarum directory, and that selinux isn't messing stuff up

Darkle

askvortsov I put the log not complete by mistake, now it is complete. It seems to be a permissions problem but I put them again and again and it doesn't change anything... SELinux is deactivated for now, and it's still the same.

askvortsov

Darkle And you've chowned the files in addition to chmodding them?

Darkle

askvortsov Finally it worked, I restarted the server and executed the permissions commands:
sudo chown -R darkle:darkle /var/www/flarum sudo chmod -R 0775 /var/www/flarum

Out of curiosity, is it advisable to return ownership to nginx once everything is working?
sudo chown -R nginx:nginx /var/www/flarum

I don't know exactly what could have happened on the server, I was going crazy, I just upgraded nginx from 1.14 to 1.18, and did a clean install of MariaDB, I didn't expect permissions problems...

clarkwinkelmann

Darkle if nginx is the user that the webserver runs as, then it should be the file owner.

Problems happen if you run php flarum command via SSH as another user, as it will create/edit files as another user. Ideally the webserver user and shell user for Flarum/Composer commands should be the same.
