Issue sh: gs: command not found exporting files as pdf

[rhand]

Was trying to export files as a pdf and had time outs after 3 minutes. Checked all PHP settings for max_execution time which is 300 seconds, max_input_time 300 seconds, post_max_size 60MB and upload_max_filesize 60MB. Started checking Nginx logs, Httpd logs, Proxy logs and so on. When I did check PHP logs I found this error

[08-Oct-2023 13:48:53] WARNING: [pool site.nl] child 699893 said into stderr: "sh: gs: command not found"

realized Ghost script was missing on my Alma Linux server so installed it

But still nothing. Export still fails in Wordpress using Fancy Product Designer. Also saw for PHP that Imagick was installed but when I did

convert --version
bash: convert: command not found

nothing was added. Then read I needed GraphicsMagick for Rhel though PHP had it already so installed it

How can I get the Plesk installed PHP FPM 8.0.3 to find Ghost and work with it well so the plugin can generate the pdf files?

 

[rhand]

By the way Imagick is working for PHP FPM already . Its ini is loaded and 3.7.0 shows in PHP Info

cat /opt/plesk/php/8.0/etc/php.d/imagick.ini
; Enable imagick extension module
extension=imagick.so

 

[rhand]

I could do

export GS_LIB=/usr/share/ghostscript/lib

or add it to the main web users's .bashrc perhaps, but sounds like an odd way to do this. On shared hosts this was never necessary. Hope someone on this forum has a better idea to have PHP Imagick play nice with Ghostscript I just installed today to allow for PDF exports using a WordPress plugin.

 

[Peter Debik]

Software installed on your server cannot be accessed when you are using the chrooted shell setting in a subscription, because there, the subscription user is limited to its own webspace. Changing that to a regular shell with "all access" pass poses huge security risks. If you want to add a program to your subscription shell, please follow this guide: https://support.plesk.com/hc/en-us/...chrooted-shell-environment-template-in-Plesk- . As an alternative, you could consider to install this PECL extension https://pecl.php.net/package/ps to create PostScript files. You can do that with the PECL install button from the admin's PHP control page in Tools & Settings.

 

[rhand]

Did not realize or think about the fact that each subscription is chrooted. That certainly causes the Ghostscript binary to not be available even after I installed it on the server as root. Also explains why I did not locate Imagick. Thanks @Peter Debik for telling me about it. Will not want to break out of the chroot env. Will check out adding a program in shell environment at a later stage. I tried to install the PECL package but it failed

I check version pkg-config:

pkg-config --version
1.4.2

so version is fine.. not sure why libps is not there or not located.

 

[rhand]

Not sure why it cannot find libps as we tried installing it and it downloaded things

Last extension list was not PECL though.. was PHP.. so is different. Issue with not finding libps installing PS PECL package still remains.

 

[rhand]

Still errors

may open an official support ticket soon. Just to export pdfs is getting rather tedious.

 

[Peter Debik]

Not all PECL extensions can be installed through the PECL installer, because some just don't behave as expected by such an extension. Maybe this is one of them. You could install the extension manually. You could also open a support ticket with Plesk support to get better individual assistance as you can let them access your server if you prefer.

When I tried it from the command line using the chrooted user for the domain name I got this

pecl install ps
WARNING: configuration download directory "/tmp/pear/download" is not writeable. Change download_dir config variable to a writeable dir to avoid this warning
Cannot install, php_dir for channel "pecl.php.net" is not writeable by the current user

so that explains something. Not sure why Plesk said it up this way, but will see how we can remedy that the best way.

 

[rhand]

-rw-r--r--. 1 root root 637247 Oct 9 12:35 ps-1.4.4.tgz

perhaps I need to use sudo... no.. I can only change to root using su as user is chrooted. So not sure how pecl install ps and have it work for the chrooted user and its chosen PHP FPM 8.0 . Also.. so earlier trial to add PS today did work.. and that was from Plesk.. so not sure why it stated

before..

 

[rhand]

So why

checking for libps... configure: error: cannot find libps using pkg-config (0.4.0 or later recommended)

I mean we do have on the installation installation through Plesk:

ll /tmp/pear/download
total 628
-rw-r--r--. 1 root root 648 Oct 9 09:16 channel.xml
-rw-r--r--. 1 root root 637247 Oct 9 12:35 ps-1.4.4.tgz

must be a path issue. But perhaps I need to run installation command as root? But how to make sure it is for chrooted subscriber and its PHP FPM 8.0.30?

 

[rhand]

Working on opening a ticket with Plesk Support while I try to work it out on my own.

 

[rhand]

Get to hear that license works but is via provider and that I cannot ask questions directly

We identified that the Plesk license was purchased not directly from Plesk but through one of the Plesk Resellers.

• Please contact your license provider for support service.
• Alternatively you can receive support directly from Plesk by purchasing monthly support subscription for your license key.
• Also you can refer to Plesk complementary support resources such as "Knowledgebase", "Facebook Community" or tweet to @PleskHelps

 

[Peter Debik]

If you bought your license from a reseller, your reseller should provide support for you. If the reseller does not provide support, here is an alternative:

[rhand]

Thanks @Peter Debik hoster TransIP.nl has opened ticket with Plesk support now so will wait for feedback,

Hi, I just installed Imagemagick to a newly formatted server and tried running the following convert command with Imagemagick.

PHP Code:

/usr/local/bin/convert -pointsize 18 -gravity "Center" -draw 'text 0,0 "634669"' /home/public_html/images/canvas.png /home/public_html/images/botcode/25d0623b4c3136dc8cc4b9f28deb2292.png
sh: gs: command not found
sh: gs: command not found
convert: no decode delegate for this image format `/tmp/magick-XXLEhTir'.
sh: gs: command not found
sh: gs: command not found
convert: no decode delegate for this image format `/tmp/magick-XXBR5ph8'.

I've googled for this error (sh: gs: command not found) and I think is something related to Ghostscript not being install on my server. How do I get around this issue? I can't find any step by step guide on how to install Ghostscript

 

[rhand]

It seems to be very difficult to get PDF export to work on a chrooted Plesk environment and it Ghostscript or Postscript PS PECL package is not installed any default and installing fails with default setup. Plesk has responded and I was told to update Chrooted env and add the program with mention that it will still not work for all programs . Hear their reaction. Do notice as we only have one user they recommended to allow /bin/bash access to all chrooted envs:

to me it appears its the only customer on the server, if the issue is caused by not being able to properly install it on chrooted environment why not provide /bin/bash access for the domains?

Alternatively please reset the chrooted environment as described here:
https://support.plesk.com/hc/en-us/...build-chroot-template-on-a-server-with-Plesk-

Then you can install PECL for PHP8 which is currently set for the domain by following the instructions here:
Go to **Tools & Settings > PHP Settings >** _**click_on_the_PHP version**_ **> Manage PECL packages**;
Choose the required package from the list and install it. Or if the package is not present in the list click **Install package** and proceed with installation.

And add whatever is required to the chrooted environment:
https://support.plesk.com/hc/en-us/...chrooted-shell-environment-template-in-Plesk-

Please note that the software thats being tried to be installed is not supported by plesk hence we have no knowledge about the installation process itself. You can make sure that its not about the software by adding another software to chroot i.e.:
https://support.plesk.com/hc/en-us/...-Composer-to-a-chrooted-environment-in-Plesk-

Step by step explanation how to have PHP PECL package Imagick work with pdf export using Ghostscript or PS PECL package has not been given.
