Description:
Dear Team,

My wordpress website is very very slow and does not open at all. I have already taken below actions.

Tracked access_log and blocked the IP address of bot attack.
Touched, and further disabled pagespeed module.
Cleared, and disabled cache.
Upgraded the Lightsail instance.
Updated wordpress-fpm timeout.
Restarted all services and the instance itself.

Currently there are no visible errors in the error_log. But there is still no improvement in the performance. It would be great if you can provide a help asap.

I have already run the support tool. Following is the support bundle code for your reference.

Warm regards,
Shishir

Hi @shishir.insane,

Thanks for using Bitnami. It looks like your PHP-FPM service is running out of resources, probably for a hight traffic on your site.

[05-Nov-2019 21:06:02] WARNING: [pool wordpress] server reached pm.max_children setting (5), consider raising it

Can you try increasing the value of the pm.max_children parameter in the /opt/bitnami/php/etc/bitnami/common.conf file and restart the services?

sudo /opt/bitnami/ctlscript.sh restart

Please note this value depends on your server size and that increasing it too much for a small server may cause performance issues. We recommend you to increase the instance type so the new values are balanced with the new instance type. Our init process will take care of detecting your new instance type and will adjust the PHP-FPM parameters according to it.

You can get more information about how to resize your server in the guide below

https://docs.bitnami.com/aws/faq/administration/change-server-type/

Hope it helps,
Gonzalo

Hi @gongomgra, I have tried as you have suggested. However, I am unable to resolve this issue. I have tried more things as well but with no success. Is there a way to export the whole wordpress data (without plugins & themes) and then import it to a new instance from command line?

I am trying to setup a new fresh instance instead spending time to revive the faulty one.

I have upgraded the instance further more and run the support tool.

I have disabled the pagespeed again.

Hi @shishir.insane,

This other user has a similar issue and he said that renaming the themes folder worked for him (he could access the admin dashboard)

https://community.bitnami.com/t/website-doesnt-load-gateway-timeout-504-again/71631/3?u=jota

sudo mv /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins.bck
sudo mv /opt/bitnami/apps/wordpress/htdocs/wp-content/themes /opt/bitnami/apps/wordpress/htdocs/wp-content/themes.bck
sudo /opt/bitnami/ctlscript.sh restart

Can you check if that works for you?

Thanks

Hi @shishir.insane,

This other user provided a different solution

https://community.bitnami.com/t/error-502-bad-gateway/71614/6?u=jota

Can you confirm you have those requests to code.php in the access.log file?

sudo cat /opt/bitnami/apache2/logs/access_log | grep code.php

If that's the case, can you check if the file exists

sudo ls -la /opt/bitnami/apps/wordpress/htdocs/code.php

and create it in the WordPress' directory if it doesn't exist?

sudo mv /opt/bitnami/apps/wordpress/htdocs/code.php /opt/bitnami/apps/wordpress/htdocs/code.php.back
sudo touch /opt/bitnami/apps/wordpress/htdocs/code.php
sudo chown bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/code.php
sudo chmod g+w /opt/bitnami/apps/wordpress/htdocs/code.php

sudo /opt/bitnami/ctlscript.sh restart

Thanks

This solution with code.php looks to be working. However, I will try to do more tests before I conclude and finally relax.

Thanks for all the support.

Thank you very much. It is working now. You saved my weekend. How can I buy you a beer?

Hi @shishir.insane,

It seems that malicious code may have been included in your site via "nulled" themes and plugins in WordPress. We published a security notice in our documentation to let the users know about it.

https://docs.bitnami.com/general/security/security-2019-11-08/

I suggest you follow the WordPress' security practices to keep your site secure and up-to-date. If you have any questions, do not hesitate to ask.

Regards
