Parallels Plesk Panel Server backup repository

Server backup repository location.

As of Parallels Plesk Panel version 9.0, the structure and location of the server backup repository have both changed.
The root backup directory is now stored in the file /etc/psa/psa.conf, while it is still set by the variable DUMP_D as before:

Backups directory

DUMP_D /var/lib/psa/dumps

Server backups, backups of resellers, clients, domains, and daily MySQL dumps are now stored in this directory.

How to verify Apache web server status - Parallels Plesk Panel for Linux/Unix.

The name of Apache 2 binary on Debian and SuSE OSes is “apache2,” not “httpd” as it is on Red Hat-based Linux distributions or FreeBSD.

# ps ax | grep httpd | grep -v grep

If not, try to start Apache from Plesk CP or via command line. If you get an error, check /var/log/httpd/error_log (/var/log/apache2/error_log on SuSE and Debian, /usr/local/psa/apache/logs/error_log on FreeBSD)

Make sure that Apache is listening on the both HTTP and HTTPS ports (80/443) on all needed IP addresses:

# netstat -l | grep http
tcp 0 0 *:http *:* LISTEN
tcp 0 0 *:https *:* LISTEN

How to enable Apache graceful restart in Plesk

APPLIES TO:

Parallels Plesk Panel 11.0 for Linux
Parallels Plesk Panel 10.4 for Linux/Unix
Parallels Plesk Panel 10.3 for Linux/Unix

By default, Parallels Plesk Panel does not use Apache graceful restart for applying new settings.

Solution:

To enable graceful restart, you should add the parameter “restart_apache_gracefully” with a “true” value to the “misc” table of the “psa” database. It can be done by the following SQL query:

mysql> INSERT INTO misc VALUES (’restart_apache_gracefully’, ‘true’);

The resize2fs program

# resize2fs -h
resize2fs 1.42 (29-Nov-2011)
Usage: resize2fs [-d debug_flags] [-f] [-F] [-M] [-P] [-p] device [new_size]

DESCRIPTION

The resize2fs program will resize ext2, ext3, or ext4 file systems. It can be used to enlarge or shrink an unmounted file system located on device. If the filesystem is mounted, it can be used to expand the size of the mounted filesystem, assuming the kernel supports on-line resizing. (As of this writing, the Linux 2.6 kernel supports on-line resize for filesystems mounted using ext3 and ext4.).

The resize2fs program does not manipulate the size of partitions. If you wish to enlarge a filesystem, you must make sure you can expand the size of the underlying partition first. This can be done using fdisk(8) by deleting the partition and recreating it with a larger size or using lvextend(8), if you’re using the logical volume manager lvm(8).

When recreating the partition, make sure you create it with the same starting disk cylinder as before! Otherwise, the resize operation will certainly not work, and you may lose your entire filesystem. After running fdisk(8), run resize2fs to resize the ext2 filesystem to use all of the space in the newly enlarged partition.

If you wish to shrink an ext2 partition, first use resize2fs to shrink the size of filesystem. Then you may use fdisk(8) to shrink the size of the partition. When shrinking the size of the partition, make sure you do not make it smaller than the new size of the ext2 filesystem!

Adding RPM Fusion Repository

Adding RPM Fusion Repository

Command Line Setup using rpm

To enable access to both the free and the nonfree repository use the following command:

Fedora 15, 16 and 17:

su -c ‘yum localinstall –nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm’

RHEL 6 or compatible like CentOS:

su -c ‘yum localinstall –nogpgcheck http://download1.rpmfusion.org/free/el/updates/6/i386/rpmfusion-free-release-6-1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/6/i386/rpmfusion-nonfree-release-6-1.noarch.rpm’
