Bitnami on AWS Lightsail, WordPress: permission issues via sFTP

Keywords: WordPress - Amazon Web Services - Technical issue - Permissions
Description:
We installed a WordPress site using a Bitnami installer on AWS Lightsail and successfully imported some media files from a source server, via a WordPress migration plugin. I needed to clean up some of the excess file imports and attempted to delete them via sFTP, but was denied. The operation worked when I did the deletion from the WordPress admin media editor. Do you know why permissions are not full? I am logging via sFTP using the master account provided at app install.

Thanks!

Hi @pro100,

Could you access the instance through SSH, run the following commands and check if that solves the issue?

sudo chown -R bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/wp-content/cache
sudo find /opt/bitnami/apps/wordpress/htdocs/wp-content/cache -type f -exec chmod 664 {} \;
sudo find /opt/bitnami/apps/wordpress/htdocs/wp-content/cache -type d -exec chmod 775 {} \;
sudo chown bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/wp-config.php
sudo chmod g+w /opt/bitnami/apps/wordpress/htdocs/wp-config.php

Hi Michiel,

I logged in as Bitnami via Putty and entered each command:
bitnami@ip-XXX:~$ sudo chown -R bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/wp-content/cache
bitnami@ip-XXX:~$ sudo find /opt/bitnami/apps/wordpress/htdocs/wp-content/cache -type f -exec chmod 664 {} \;
bitnami@ip-XXX:~$ sudo find /opt/bitnami/apps/wordpress/htdocs/wp-content/cache -type d -exec chmod 775 {} \;
bitnami@ip-XXX:~$ sudo chown bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/wp-config.php
bitnami@ip-XXX:~$ sudo chmod g+w /opt/bitnami/apps/wordpress/htdocs/wp-config.php
bitnami@ip-XXX:~$

The command line editor just returned without a message back on each step, so i assume it executed them without error. However I am still unable to selectively delete files or folders in the Uploads directory, from sFTP.

Hi @pro100,

We have a Support Tool that will gather relevant information for us to debug the issue. Could you please download and execute it on the machine where the stack is running by following the steps described in the guide below? You must click on the platform or cloud that you are using to find the correct instructions.

How to Run the Bitnami Support Tool

Please note that you need to paste the code outputted by the tool in your reply.

Thanks Michiel. I updated the Support Tool and it is running me through a series of questions. I am stuck when it asks for the SMTP server credentials (hostname, then port, user, password). I connected WordPress to a AWS SES account via a plugin, this is done at the app level. Not sure what I need to use for server level SMTP?

Hi @pro100,

As this issue is unrelated to SMTP could you skip running the health check tools? The bnsupport tool collects log and permission info by default.

Thanks Michiel. I thought the health check was necessary to collect the information. I declined and it ran to completion.

Hi @pro100,

I just checked that the files you are trying to remove were created by Apache (using the WordPress Dashboard) so in order to give the bitnami user permissions to remove them, please run the following commands

sudo chown -R bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/wp-content
sudo chmod -R g+w /opt/bitnami/apps/wordpress/htdocs/wp-content

This way, both the bitnami user and the daemon group (Apache and WordPress) can write in all the directories under wp-content

Thanks

Jota, now this works! Thanks to you both for the guidance.

These commands seem like the key thing to run for users importing content from the All in One migration plugin, which owns exclusive rights to the files by default.

Hi @pro100,

Great to hear it works.
