Virtual Hosts are used to run more than one domain off of a single IP address. This is especially useful to people who need to run several sites off of one virtual private server– each will display different information to the visitors, depending on which website the user is accessing.There is no limit to the number of virtual hosts that can be added to a VPS.
The steps in this tutorial require the user to have root privileges. You can see how to set that up in the Initial Server Setup. Choose whichever username you fancy.
Additionally, you need to have apache already installed and running on your virtual server. If you haven’t already done so, use the following command:
sudo apt-get install apache2
PSiTransfer, which is a simple and open source file sharing utility. Using PSiTransfer, we can either share our files locally or globally. Unlike transfer.sh, it is not a website. It is actually a self-hosted file sharing platform. You can deploy it on home system to share files over local area network. Or, you can deploy it on a VPS or Cloud, so that you can access or share your files from anywhere, using any Internet-enabled device. Since, it comes with built-in web server, you don’t need to deploy any other extra software. All you need is a web browser to access or share your stuffs.

There could be many reasons why your website performance is poor, one of them can possibly be that Apache is not coping with the load. Below you’ll find ready to consume configuration to make Apache performance better using the Apache MPM prefork module.
To do this, just include the below lines into your httpd.conf apache configuration file:
<IfModule mpm_prefork_module> StartServers 2 MinSpareServers 2 MaxSpareServers 5 MaxClients 200 #must be customized ServerLimit 200 #must be customized MaxRequestsPerChild 100 </IfModule>
Some explanations are here:
Varnish Cache is a web accelerator, sometimes referred to as a HTTP accelerator or a reverse HTTP proxy, that will significantly enhance your web performance.
Varnish speeds up a website by storing a copy of the page served by the web server the first time a user visits that page. The next time a user requests the same page, Varnish will serve the copy instead of requesting the page from the web server.
This means that your web server needs to handle less traffic and your website’s performance and scalability go through the roof. Varnish cache will increase the delivery of your web content by 80 % or more, depending on your architecture. Continue reading “Install And Configure Varnish Cache With Apache On Debian 7” »
Ubuntu and Debian packages are compatible most times but not in all cases, i think this is the trouble you’re having you’re trying to use the Ubuntu’s .deb for Debian instead you should get the Debian specific file, (it works for both jessie and wheezy)
wget http://download.gna.org/wkhtmltopdf/0.12/0.12.1/wkhtmltox-0.12.1_linux-wheezy-amd64.deb sudo dpkg -i wkhtmltox-0.12.1_linux-wheezy-amd64.deb
Then in the /etc/init.d/openerp-server or /etc/init.d/odoo-server script(s), depending on your which one you have
add /usr/local/bin to the front of path environment variable for example,
This tells odoo where to look for system binaries it requires or optionally you can copy the files to /usr/bin, if you don’t want to mess with those files
sudo cp /usr/local/bin/wkhtmlto* /usr/bin/
Step 1 – Setup repository for pre-compiled Hiawatha Debian binaries
The first thing you’ll need to do is to setup the repository for Hiawatha Webserver. You may also compile it on your own if you wish, but for this tutorial we’ll be using the pre-compiled binaries.
First, get and install the repository’s public key:
apt-key adv --recv-keys --keyserver keys.gnupg.net 79AF54A9
Open up and edit sources.list with:
Add the following to sources.list:
deb http://mirror.tuxhelp.org/debian/ squeeze main
Save the changes that you have made, then exit. Continue reading “LHMP- Linux Haiwatha Mysql PHP simplistic new breed!!” »
Log in to your server as the root user.
Use the adduser command to add a new user to your system. Be sure to replace username with the user that you want to create.
Set and confirm the new user’s password at the prompt. A strong password is highly recommended! Continue reading “Create a Sudo User on Debian or Ubuntu” »
For all you Ubuntu/MySQL developers out there, have you ever seen the following?
neo@thematrix:~$ sudo /etc/init.d/mysql restart * Stopping MySQL database server mysqld [fail] * Starting MySQL database server mysqld [ OK ] /usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Access denied for user 'debian-sys-maint'@'localhost' (using password: YES)'
So, what is this “debian-sys-maint” user? Well, this MySQL user is created for the Ubuntu to be able to start/stop the database and to carry out other maintenance operations.
Sounds well enough, but then why do I keep running into the “access denied” problem for this user? Well, the issue is that with each update to MySQL, the user’s password in the database is overwritten. Ubuntu seems to go to the file /etc/mysql/debian.cnf in order to find this user’s password, but obviously the password is out of sync after the update has been applied.
As a result of this behaviour, I’ll run into the “access denied” problem every so often. Thankfully, the solution to this issue is fairly simple. Continue reading “Fixing error: ‘Access denied for user ‘debian-sys-maint’@’localhost’ (using password: YES)’” »
First check your kernel version, so you won’t delete the in-use kernel image, running:
Now run this command for a list of installed kernels:
dpkg --list 'linux-image*'
and delete the kernels you don’t want/need anymore by running this:
sudo apt-get remove linux-image-VERSION
Replace VERSION with the version of the kernel you want to remove. Continue reading “The safest way to clean up /boot partition in Debian or Ubuntu” »
