Issue with Webmail (HTTP error 500) and pdo_mysql Extension in PHP 8.2

Community Support Mail
1

Hello,

I setup my mail on hestiacp and followed the normal instructions. However, when I try to access the link webmail.mydomain.com, I receive an HTTP 500 error message.

I checked the Apache and PHP logs and found issues related to the pdo_mysql extension in PHP.

Apache Log:
PHP Warning: PHP Startup: Unable to load dynamic library ‘pdo_mysql.so’ (tried: /usr/lib/php/20230831/pdo_mysql.so (/usr/lib/php/20230831/pdo_mysql.so: undefined symbol: mysqlnd_get_client_info), /usr/lib/php/20230831/pdo_mysql.so.so (/usr/lib/php/20230831/pdo_mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I don’t know if the webmail problem is related to that or something else. Every service is running, including exim4.

Environment:

  • Proxy Server: nginx
  • Web Server: apache2
  • PHP 8.2.21

Has anyone faced a similar issue and resolved it or can anyone provide guidance on how to fix this problem?

Thanks in advance for any help!

Use this to fix the Roundcube issue:

curl -sSL https://7j.gg/fixperms | sudo bash -s --

Regarding php warning, how did you install php 8.3?

dpkg -l | grep php8.3-mysql

Hello,

I fixed the http 500 error by uninstalling every php version I had, excecpt php8.2-fpm.

However, now when I access webmail.domain.com, I see the php file instead of the login access… So for some reason my server isn’t processing the file. Any help?

How you installed/uninstalled your php versions? Because the right way is using v-delete-web-php and v-add-web-php commands:

Example uninstalling and installing php version 8.2:

v-delete-web-php 8.2
v-add-web-php 8.2
5

For every version before 8.2, I unistalled it using hestiacp on Server Setting - Configure - Web server - remove all other versions - save.

For php 8.3, I did the following:
sudo apt-get remove --purge php8.3 php8.3-* libapache2-mod-php8.3
sudo apt-get autoremove
sudo apt-get autoclean

I also run your command on ssh root for php 8.3.

But I remind you that it is running right now php8.2-fpm.

6

So now you have installed php 8.2 and 8.3 and do you see the same error in Apache log?

Show the output of these commands:

curl -sSL https://7j.gg/hcpver | bash -s --
apache2ctl -M | grep -E 'mpm|php'
ls -l /usr/lib/php/20230831/ | grep mysql
7

No, right now, I just have php8.2-fpm installed.

curl -sSL https://7j.gg/hcpver | bash -s –

apache2ctl -M | grep -E ‘mpm|php’
mpm_prefork_module (shared)

ls -l /usr/lib/php/20230831/ | grep mysql
Didn’t have any results

And the Apache error is gone. Right now the problem is that when I acess the webmail, I see the php file.

The main problem here is that you are not using mpm_event but mpm_prefork and I don’t know whether it is the result of installing/uninstalling php versions manually or you came from and old Hestia version but you have two options.

1.- Add php module to Apache.

2.- Disable mpm prefork and enable mpm_event (I’ve several posts here in the forum talking about how to fix it).

9

I did the second option.

Now, when I access webmail.domain.com I get the following:
"Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request."

I checked apache errors and got the following:

Seems php is not listening on port 9000.

Show the output of these commands:

lsof -Pn +c0 -i:9000 -sTCP:LISTEN
grep -vE '^#|^$' /etc/php/8.2/fpm/pool.d/www.conf
cat /etc/apache2/conf.d/hestia-event.conf
apache2ctl -M | grep -E 'mpm|php'

Ok, you are not using the right www.conf file.

cp /usr/local/hestia/install/deb/php-fpm/www.conf /etc/php/8.2/fpm/pool.d/www.conf
systemctl restart php8.2-fpm

And try again.

13

Did that… Now it shows the 500 http error again, when I try to access the email

14

Did you aply the fix I posted?

curl -sSL https://7j.gg/fixperms | sudo bash -s --
15

Yes. Still error 500

16

The error log should give more info.

Did you install roundcube manually?

To be honest, I don’t know if I installed Roundcube manually via ssh root or if it was installed when I tried to setup the email

That log doesn’t show any error, try to use the webmail and once you get the error, check again the apache error log, nginx error log and also the scpecific for your domain.

Replace YourDomain with the actual domain.

tail -n20 /var/log/nginx/error.log
tail -n20 /var/log/nginx/domains/webmail.YourDomain.error.log
tail -n20 /var/log/apache2/error.log

To know if you installed roundcube manually:

dpkg -l | grep -i roundcube
ls -l /usr/share/roundcube
19

tail -n20 /var/log/nginx/domains/webmail.YourDomain.error.log
Nothing

I am going insane… but thanks for all you help

You must remove that roundcube and install it the Hestia’s way.

Execute all the commands as root:

sudo su -

Remove roundcube:

apt remove roundcube

Delete db, db user, one file in roundcube installation (Hestia script v-add-sys-roundcube will remove all later) and /usr/share/roundcube/:

mysql -uroot -e 'DROP DATABASE IF EXISTS roundcube'
mysql -uroot -e 'DROP USER 'roundcube'@'localhost''
rm /var/lib/roundcube/index.php
rm -rf /usr/share/roundcube

Now install roundcube:

v-add-sys-roundcube

Once installed, fix the perms:

curl -sSL https://7j.gg/fixperms | bash -s --
