How to Install Nginx on CentOS with Yum

Nginx is a popular lightweight alternative to Apache. Installing it with the yum package manager is simple:

# yum update

# rpm -Uvh http://download.fedora.redhat.com/pub/epel/5Server/x86_64/epel-release-5-4.noarch.rpm

# yum install nginx

Start Nginx:

# /etc/init.d/nginx start

Check if Nginx is running at: http://xx.xx.xx.xx – You should see a default Nginx page.

Set Nginx to start automatically in case of reboot:

# /sbin/chkconfig nginx on

How to Install Deluge Seedbox VPS on Ubuntu

Though it is one of the newest seedbox Web UIs, Deluge has proven to be a tested favorite among seeders. Deluge offers one of the most polished and efficient graphical front-ends, and is often called the fastest seedbox VPS UI. This guide will walk you through the setup of a Deluge/deluge-web VPS based on Ubuntu (recommended for 10.04 or above).

Access your VPS as the root user via SSH, and run the following commands:

# adduser –disabled-password –system –home /var/lib/deluge –gecos “Deluge server” –group deluge

# touch /var/log/deluged.log

# touch /var/log/deluge-web.log

# chown deluge:deluge /var/log/deluge*

Install Deluge:

# apt-get update && apt-get upgrade

# apt-get install deluge-common deluged deluge-web

Open the deluge-daemon file:

# vi /etc/default/deluge-daemon

Press “A” to enter edit mode, and copy in the following:

# Configuration for /etc/init.d/deluge-daemon

# The init.d script will only run if this variable non-empty.

DELUGED_USER=”deluge”

# Should we run at startup?

RUN_AT_STARTUP=”YES”

Press ESC, then type :wq and press enter to save and exit the file. Now we will create an init script for the Deluge daemon:

# vi /etc/init.d/deluge-daemon

Copy the following into the file:

#!/bin/sh

### BEGIN INIT INFO

# update-rc.d deluge-daemon defaults

You can now reboot your VPS; if everything worked, you will be able to access Deluge at http://xx.xx.xx.xx:8112 with the default password “deluge”. Enjoy!

How to Install VNC w/ Ubuntu Desktop on VPS

Similar to RDP for Windows servers, Ubuntu desktop and TightVNCServer will allow you to connect to a remote desktop running on your Linux VPS. This tutorial will guide you through the setup of a basic desktop and VNC server.

Before anything, update your system:

# apt-get update

# apt-get upgrade

Install Ubuntu Desktop:

# apt-get install ubuntu-desktop

Setup gdm:

# apt-get install gdm

# /etc/init.d/gdm start

Install and configure TightVNCServer:

# apt-get install tightvncserver

# vncserver :1 -geometry 1024×768 

# vncserver -kill :1

Open the VNC configuration file with vi:

# vi  ~/.vnc/xstartup

Press “a” to enter edit mode, then add the following to the bottom of the file:

gnome-session &

Log in to SolusVM and reboot the VPS. Then, access the VPS via SSH again, and start the VNC server:

# vncserver :1 -geometry 1024×768 

You should now be able to use a desktop VNC client to access the remote desktop at:

• IP Address: [your server's main IP]
• Port: 1 (or 5901, 5902 for desktop :2, etc)
• Password: [password you set earlier]

Note that some VNC clients will not have a Port setting; instead, you will need to enter IP Address: xx.xx.xx.xx:1

In case you forget your password, or want to reset it later:

# vncpasswd

How to Setup Ruby on Rails for CentOS or Fedora

This tutorial will guide you through setting up a basic Ruby on Rails environment, installing:

• Ruby 1.8.7
• RubyGems 1.8.15
• Rails 3.1.3
• Sqlite3

# yum update

# yum install ruby ruby-devel ruby-irb ruby-rdoc ruby-ri

# ruby -v

# mkdir ~/sources

# cd ~/sources

# wget http://rubyforge.org/frs/download.php/45905/rubygems-1.3.1.tgz

# tar xzvf rubygems-1.3.1.tgz

# cd  rubygems-1.3.1

# yum install sqlite-devel

# gem install sqlite3-ruby

# yum install postfix subversion -y

How to Update Your VPS Timezone

You may find that your virtual server’s default timezone is not the timezone you (or your users) reside in. Updating your timezone is simple:

First, log in to your VPS as the root user via SSH, then run the following command to list all available timezones (there will be many):

# find /usr/share/zoneinfo/

You can use grep to refine the search:

# find /usr/share/zoneinfo/ | grep -i turkey

Once you have selected a timezone, create a symbolic link to /etc/localtime:

# ln -f -s /usr/share/zoneinfo/CST6CDT /etc/localtime

To verify the timezone change, use date:

# date

That’s it! Your new timezone should be set.

How to Install VNC w/ GNOME on Debian VPS

VNC is a desktop sharing system that will allow you to connect to a Linux desktop from your home PC, for easy remote management of your VPS. This walkthrough will guide you through the installation of a VNC server on Debian.

Before starting, log in to your VPS as the root user, and run the following:

# apt-get update

# apt-get upgrade

1. Install GNOME:

#apt-get install gnome-desktop-environment

2. Install some required fonts:

# apt-get install xfonts-100dpi

# apt-get install xfonts-100dpi-transcoded

# apt-get install xfonts-75dpi

# apt-get install xfonts-75dpi-transcoded

# apt-get install xfonts-base

3. Install the VNC server:

# apt-get install tightvncserver

4. Start TightVNCServer for the first time, it will copy config files and prompt you for a password:

# tightvncserver :1

5. Stop the VNC server, for additional configuration:

# tightvncserver -kill :1

6. Edit the xstartup file:

# vi ~/.vnc/xstartup

Press “A” to enter edit mode. Replace the contents of the file with the following (or edit to match):

#!/bin/shxrdb $HOME/.Xresources
xsetroot -solid grey
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
# x-window-manager &
gnome-session &

Press ESC, type :wq, then press enter to save and close the file.

7. Start the VNC server with your desired resolution:

# tightvncserver -geometry 1024×768 :1

You can now use a desktop VNC client to access your server’s GNOME desktop. In your VNC client (TightVNC, for example), enter your server’s main IP address, Port 1 (or 5901, alternately), and the password you set earlier to connect to the desktop.

How to Check VPS Memory/RAM Usage

In the course of monitoring your VPS, one of the first things you will want to check is RAM (memory usage). Linux includes a few easy-to-use tools, including free and ps, described here:

The simplest memory reporting tool is free. To use it, simply run:

# free -m

You will see an output like this:

total       used       free     shared    buffers     cached

Mem:           512        462         49          0         46        127

-/+ buffers/cache:        287        224

Swap:         2047          0       2047

How to Import/Export MySQL Databases with SSH

# mysqldump -u username -p database_name > dumpfile.sql

# mysql -u username -p database_name < dumpfile.sql

How to Update MySQL Root/User Password

If MySQL is installed, but you have never set a root password, you can do so by running this command via SSH:

# mysqladmin -u root password NEWPASSWORD

To update the root password for MySQL from an existing password, use the following instead:

# mysqladmin -u root -p’oldpassword’ password newpass

To update the password of a MySQL user besides root:

# mysqladmin -u vivek -p oldpassword password newpass
