Nginx 502 error on Wordpresss

aaP_metin2tugaz

I installed aapanel because i'm tired of cyberpanel.
Well, I'm liking it, but i'm facing some issues.

I have a wordpress job portal and i need to accept various job offers. With aapanel nginx php7.3 when I accept multiple offers it shows "502 bad gateway" - it never happen before. I never used nginx so I don't know what to do.

Someone can give some tips?
My server: 6 cores, 16gb ram, 100gb nvme

Error log:
[error] 29226#0: *3605 recv() failed (104: Connection reset by peer) while reading response header from upstream

Hi Jose,
Thank you for the fast answer, I really appreciate it.
I already have the 16 GB configuration selected, what more should I do?

Regards.

aaP_metin2tugaz yahooo, another one
"CentOS 7.1+ (Ubuntu20, Debian10), to ensure that it is a clean operating system, there is no other environment with Apache/Nginx/PHP/MySQL installed (the existing environment can not be installed)"
Install apc.
Use redis or apcu (I prefer apcu)
did you forget about URL rewrite?
php parameters above are too small. I use:

on 8 GB vps.
and for Maria DB 10.5

but on a Centos 7 VPS

Thanks for your help.
I tried your configurations, but seems the same thing. I'm using MYSQL 8, Redis and I don't forget URL Rewrite, btw. 🙂

idflorin

aaP_metin2tugaz you could try to switch to apache?

aaP_metin2tugaz

idflorin Well, I migrated to openlitespeed with php7.4 and happens the same ._,

idflorin

aaP_metin2tugaz btw, my opcache settings
opcache.enable = 1 opcache.memory_consumption=256 opcache.interned_strings_buffer=32 opcache.max_accelerated_files=80000 opcache.revalidate_freq=7200 opcache.fast_shutdown=1 opcache.enable_cli=1 opcache.jit_buffer_size=256m opcache.jit=1205

aaP_metin2tugaz

idflorin Still not working. I don't know what to do more, maybe I migrate again to cyberpanel :/

idflorin

aaP_metin2tugaz the only thing that remains is to switch to PHP8.0. When I switched my sites I saw a 10-15 improvement. Btw, my sites are non-WordPress 😁 .

aaP_metin2tugaz

idflorin It would be an option, but I have one plugin isn't yet compatibly with php8... But yeah, thanks a lot for your help! 🙂

aaP_metin2tugaz

idflorin Btw, I try to restart php-pm but it gives me follow error: php-fpm.service not found, this is normal?

idflorin

aaP_metin2tugaz no its not. on Centos 7 you could run
sudo yum check-update uname -mrs sudo yum update
This is the first thing I do before installing aapanel

idflorin

aaP_metin2tugaz on your VPS is advisable to make a snapshot before making major changes, like system update

I found php-fpm it wasn't working. I needed to remove the /tmp/ socket file from php-fpm to be able to active php-fpm. Now, although it's slowly to accept offers, now it doesn't give 502 bad gateway.

Thx everyone for helping me!
