Could not open archive dir for / Could not open archive mbox dir

/usr/local/cpanel/scripts/update_mailman_cache

How to fix the errors

Could not open archive mbox dir for somelist: No such file or directory at /usr/local/cpanel/Cpanel/Mailman/DiskUsage.pm
Could not open archive dir for somelist: No such file or directory at /usr/local/cpanel/Cpanel/Mailman/DiskUsage.pm

Solution

If we have a list named list1_webinformat.com the error is

Could not open archive mbox dir for list1_webinformat.com: No such file or directory at /usr/local/cpanel/Cpanel/Mailman/DiskUsage.pm

and we have to create 2 dirs

mkdir /usr/local/cpanel/3rdparty/mailman/archives/private/list1_webinformat.com.mbox
mkdir /usr/local/cpanel/3rdparty/mailman/archives/private/list1_webinformat.com

After we create the needed directories we run 2 commands

/usr/local/cpanel/scripts/fixmailman

/scripts/update_mailman_cache

Ubuntu server no login console

After boot there was no console prompt to login.

The issue was related to the VGA resolution.

To fix Ubuntu server no login console

modify in /etc/default/grub

# Grub Resolution
GRUB_GFXMODE=1024x768x24

# Kernel param to set a port to resolution and vertical refresh.
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset video=VGA:[email protected]"

Of course, you can set resolution to suit your needs by replacing 1024x768x24 to whatever you need.

Make phpMyAdmin work with Varnish Cache.

How to make phpMyAdmin work on Nginx server with Varnish Cache?

Assuming you have configured Varnish Cache to drop cookies here is what you have to change to make phpMyAdmin work properly on your Nginx server.

  1. after you install phpMyAdmin make a symbolic link
    sudo ln -s /usr/share/phpmyadmin/ /usr/share/nginx/www
  2. edit /etc/varnish/default.vcl – add in  sub vcl_recv
    if (req.url ~ "^/phpmyadmin") {
    return (pass);
    }

    – add in sub vcl_fetch

    if (req.url ~ "^/phpmyadmin") {
    return (hit_for_pass);
    }
  3. edit /etc/phpmyadmin/config.inc.php and set
     $cfg['PmaAbsoluteUri']="http://yourdomain.com/phpmyadmin/";

You can see that it’s not that complicated to make phpMyAdmin work with Varnish Cache.
