export.php was not found while backing up databases through phpmyadmin

  This error is mainly caused when database size is more and you are trying to backup it up using phpmyadmin.   Increase memory_limit in /usr/local/psa/admin/conf/php.ini to higher value and restart Plesk Control Panel after that. Ideally 512M of memory_limit should fix the issue. contact@webhostingsupport.info

Wine is a free software application that aims to allow computer programs written for Microsoft Windows to run on Unix-like  operating systems. Wine also provides a software library, known as Winelib, against which developers can compile  Windows applications to help port them to Unix-like systems.

SSH the server as root and refer to following steps to install wine on centos server.

1) Installing rpmforge rpm.

root@server [~]# cd /usr/local/src/

root@server [/usr/local/src]# wget http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

 

2) Install the rpmforge rpm.

root@server [/usr/local/src]# rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.i386.rpm

3)  Install wine.

root@server [/usr/local/src]#yum install wine -y enablerepo=rpmforge

4) Launch Wine from the Centos Applications menu.

 

That’s All.

error: subsystem: cannot stat /usr/libexec/sftp-server

Categories:

by

Unable to connect SFTP  via FTP client on Plesk server.

FTP logs show following:

sshd[5869]: subsystem request for sftp
error: subsystem: cannot stat /usr/libexec/sftp-server:
No such file or directory
As mentioned in the error, file /usr/libexec/sftp-server was not present.
To fix this problem you can refer to following steps:
1) 


root@office1 [~]#locate sftp-server
/usr/libexec/openssh/sftp-server


2) Edit ssh configuration file /etc/ssh/sshd_config and comment
the line containing "/usr/libexec/sftp-server"

and add new line which
will look like “Subsystem      sftp     /usr/libexec/openssh/sftp-server” 


# override default of no subsystems
#Subsystem      sftp    /usr/libexec/sftp-server
Subsystem      sftp     /usr/libexec/openssh/sftp-server


3) reload sshd service


root@server[~]#/etc/init.d/sshd reload

Now try connecting to SFTP. It will work.

boot Ubuntu into single user mode

Categories:

by

Booting UBUNTU into single user mode is slightly different then CENTOS.

1) Hold the Shift key at boot to display the Grub boot menu. If you fail to press Shift key then you will not see boot menu
2) Select the first Grub entry, it will be similar to:

Ubuntu, with Linux 2.6.32-22-generic-pae

3) Press e to edit the the Grub entry.
4) Now you can look for the line similar to following:

linux /boot/vmlinuz-2.6.32-22-generic-pae
root=UUID=xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx
ro vga=794 quiet splash

5) Go to the end of the line and change the line to so it looks like following:

linux /boot/vmlinuz-2.6.32-22-generic-pae
root=UUID=xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx
init=/bin/bash rw

6) Now Hit crtl+x to boot the server into single user mode.

Thats All :)

The MySQL® server is currently offline

Categories:

by

While going to cPanel >> Mysql database I was getting following error:

The MySQL® server is currently offline

On checking server side I found that mysql service is online and still cPanel was throwing the error.

FIX:

This issue is mainly caused when mysql root password is not set on the server.
To fix the issue Login to WHM as root and go to SQL Services >> MySQL Root Password and reset the password.

 

Now try creating Mysql database from cPanel.
