Summary of the issue:
Can you please help me with the permission error I am facing when I try to configure ClamAV for my Nextcloud server? Thank you for your time.
I installed ClamAV following this documentation
I want to proceeed with configuration of ClamAV from Nextcloud side.
When i want to save ClamAV Daemon (Socket) configuration (in Administration settings - Security), i get error:
“Cannot connect to “/var/run/clamd.scan/clamd.ctl”: Permission denied (code 13)”
I tried to verify which user runs the apache webserver (commands used with AI help):
sudo grep -E ‘^(User|Group)’ /etc/httpd/conf/httpd.conf
User apache
Group apache
# parent and worker processes
ps -eo user,comm | grep httpd
root httpd #only once
apache httpd
apache httpd
…
in /etc/clamd.d/scan.conf - I have these options:
LogFile /var/log/clamscan/clamd.scan.log
LocalSocket /var/run/clamd.scan/clamd.ctl
LocalSocketMode 660 (#also tried 766, no success)
LocalSocketGroup virusgroup
User clamscan
#groups membership
cat /etc/group
clamupdate:x:981:
virusgroup:x:980:clamupdate,clamscan,apache
clamscan:x:979:
#folders and logs ownership
chown clamupdate:virusgroup /var/log/clamav
chown clamupdate:virusgroup /var/log/clamav/freshclam.log
chown clamscan:virusgroup /var/log/clamscan
chown clamscan:virusgroup /var/log/clamscan/clamd.scan.log
chown clamscan:virusgroup /var/run/clamd.scan
chmod 750 /var/log/clamav
chmod 640 /var/log/clamav/freshclam.log
chmod 750 /var/log/clamscan
chmod 640 /var/log/clamscan/clamd.scan.log
chmod 755 /run/clamd.scan
SELinux (commands by AI)
semanage fcontext -a -t antivirus_log_t “/var/log/clamav(/.)?"
semanage fcontext -a -t antivirus_log_t "/var/log/clamscan(/.)?”
semanage fcontext -a -t antivirus_var_run_t “/var/run/clamd.scan(/.*)?”
restorecon -Rv /var/log/clamav
restorecon -Rv /var/log/clamscan
restorecon -Rv /var/run/clamd.scan
NOTHING OF THE ABOVE HELPS, ERROR STILL PRESENT.
Steps to replicate it (hint: details matter!)
-
Install ClamAV
-
Configure Daemon (Socket) in Nextcloud

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
