# Installation

## Installation Problems

1. You can re-run the installer / updater from the command line to check for any errors:

AlmaLinux / CloudLinux / RHEL / Rocky Linux

```
/usr/local/psa/admin/bin/modules/warden/install.sh
```

Debian / Ubuntu

```
/opt/psa/admin/bin/modules/warden/install.sh
```

2. Try restarting the Amavis daemon and ClamAV daemon and check for any errors:

AlmaLinux / CloudLinux / RHEL / Rocky Linux

```
// amavis restart 
systemctl restart amavisd

// amavis log file
tail -f /var/log/maillog 

// amavisd-milter restart 
systemctl restart amavisd-milter

// amavisd-milter log file
tail -f /var/log/maillog 

// clamav restart 
systemctl restart clamd@scan

// clamav log file
tail -f /var/log/clamd.scan 

// freshclam restart
systemctl restart clamav-freshclam

// freshclam log file
tail -f /var/log/freshclam.log

// dovecot restart
systemctl restart dovecot

// dovecot log file
tail -f /var/log/maillog
```

Debian / Ubuntu

```
// amavis restart 
systemctl restart amavis

// amavis log file
tail -f /var/log/maillog 

// amavisd-milter restart 
systemctl restart amavisd-milter

// amavisd-milter log file
tail -f /var/log/maillog 

// clamav restart 
systemctl restart clamav-daemon

// clamav log file
tail -f /var/log/clamav/clamav.log 

// freshclam restart 
systemctl restart clamav-freshclam

// freshclam log file
tail -f /var/log/clamav/freshclam.log

// dovecot restart
systemctl restart dovecot

// dovecot log file
tail -f /var/log/maillog
```

## Common Problems

**Wrong time on the server**
Make sure that the date and time on the server is correct. The wrong date and time will cause the SSL certificate connections that the installer uses to fail. You can sync your server time using the command:

```
// sync the time
/usr/sbin/ntpdate -b -s time.nist.gov

// re-run the installer and check for errors
/usr/local/psa/admin/bin/modules/warden/install.sh
```

**Not enough memory to start the ClamAV daemon:**
If you see `Cannot allocate memory` in your ClamAV daemon logs this means that you do not have enough free memory in order to start the ClamAV daemon. Free up some memory on your server or upgrade your system memory then restart the Anti-virus service.

```
// AlmaLinux / CloudLinux / RHEL / Rocky Linux
# grep 'Cannot allocate memory' /var/log/clamd.scan 

// Debian / Ubuntu
# grep 'Cannot allocate memory' /var/log/clamav/clamav.log 

Sun Feb 10 03:15:52 2019 -> ERROR: daemonize() failed: Cannot allocate memory
Sun Feb 10 03:25:51 2019 -> ERROR: daemonize() failed: Cannot allocate memory
Sun Feb 10 03:32:12 2019 -> ERROR: daemonize() failed: Cannot allocate memory
```

**Incorrect permissions your /var/tmp or /tmp directories used by the ClamAV:**
If you see `Failed to create temporary file` in your ClamAV daemon this means that your `/var/tmp` or `/tmp` permissions are not writable by the ClamAV daemon.

```
// AlmaLinux / CloudLinux / RHEL / Rocky Linux
# grep 'Failed to create temporary file'  /var/log/clamd.scan 

// Debian / Ubuntu
# grep 'Failed to create temporary file' /var/log/clamav/clamav.log 

Thu Apr 18 22:31:55 2019 -> ERROR: Failed to create temporary file
Thu Apr 18 22:31:55 2019 -> ERROR: Failed to create temporary file
```

To fix the tmp permissions change the permissions then restart the ClamAV daemon service:

```
chmod 777 /var/tmp /tmp
```

## Un-installing

You can run the uninstaller from the command line to completely remove the extension:

```
/usr/local/psa/bin/extension --uninstall warden
```

If you still have problems just open a support ticket in our client area to have an experienced technician diagnose and fix the problem for you.
