LNMP Server on CentOS

Step 1. install yum repo

• //32 bit
  rpm -ivh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

  rpm -ivh *.rpm
• //change MySQL root password：
  service mysql start
mysqladmin -u root password 'yourpasswd'
service mysql stop

Step 3. Add www account

• groupadd www
useradd -g www -d /home/www www
  // We add www as user of nginx and php-fpm

Step 4. install php

• yum install php53u-cli php53u-common php53u php53u-devel php53u-mysql php53u-xmlrpc php53u-xml php53u-gd php53u-pdo php53u-tidy php53u-mcrypt php53u-mbstring php53u-pear php53u-pecl php53u-pecl-memcache php53u-pecl-apc php53u-fpm
  //The current PHP version is 5.3.5-3, IUS' package's name is php53u
  //You can run command blew to find out lastest version
  yum list | grep -w \.ius\.

Step 5. configure php-fpm

• //setup php-fpm
  vim /etc/php-fpm.d/www.conf
  //Find Unix user/group of processes
  //change user & group to www

Step 6. Install Nginx

• //visit http://nginx.org/en/download.html to get lastest Nginx
  //for example, we use http://nginx.org/download/nginx-0.9.5.tar.gz

  yum install pcre pcre-devel # these are depend by nginx
cd /tmp
wget http://nginx.org/download/nginx-0.9.5.tar.gz
tar -zxvf nginx-*.tar.gz
cd nginx-*
./configure --user=www --group=www --conf-path=/etc/nginx/nginx.conf --with-http_stub_status_module --with-http_ssl_module
make
make install
  //register nginx as a service
  vim /etc/init.d/nginx
  //paste the script blew then run: chmod 755 /etc/init.d/nginx

  #!/bin/sh
#
# nginx - this script starts and stops the nginx daemin

By the way, there is an easy solution which help you do the same, try LNMP Installer for RHEL & CentOS

Set up a Minecraft Server on CentOS

Setting up a Minecraft server can be pretty difficult if you don't know what you're doing. This tutorial is to simplify running it on CentOS 5.

We'll need to following:

- Dedicated Server / Xen based VPS
- CentOS 5.x 32bit/64bit
- 1GB of RAM or more
- Latest Java JDK
- Minecraft Server

Let's start with getting a Xen VPS, grab one from PhotonVPS. You'll need a Xen one, so I'll recommend a WARP2 or higher.

Now, let's get started by installing Java-JDK:

yum install java-1.6.0-openjdk

Now, let's check if Java was installed:

which java

It should display the following if it was properly installed:

/usr/bin/java

We're done with that now, let's create a directory for Minecraft then install it:

1. Make sure we're in the root directory still:

cd

2. Now let's create the directory:

mkdir Minecraft

3. Enter the directory:

cd Minecraft

4. Time to get Minecraft:

wget http://minecraft.net/download/minecraft_server.jar

5. We'll need to make sure Minecraft as all the correct permissions:

chmod +x minecraft_server.jar

Minecraft is now installed!

From here we'll need to install "screen" to keep the Minecraft server running after we close the SSH session.

Install screen:

yum install screen

Now, we'll use the screen and run Minecraft from there.

screen

Starting up Minecraft now:

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

(*1024 value can be changed depending on how much RAM your VPS has)
Ex. 512MB VPS - java -Xmx512M -Xms512M -jar minecraft_server.jar nogui
Ex. 2048MB VPS - java -Xmx2048M -Xms2048M -jar minecraft_server.jar nogui

To get back to the normal screen now you'll have to do the following:

Control + a + d

To get back to the screen where Minecraft is running:

screen -r

That's it for getting Minecraft up and running on CentOS!

CentOS – Installing Nginx via yum

Nginx (pronounced “Engine X”) is a lightweight web server that offers speed and flexibility without all of the extra features that larger web servers like Apache offer. Although it is a free and open source application, CentOS does not offer the latest version in its default YUM repository. To install it, you need to add the EPEL (Extra Packages for Enterprise Linux) repository, which is part of the Fedora Project.

1. Install the EPEL repository:

# rpm -Uvh http://download.fedora.redhat.com/pub/epel/5Server/x86_64/epel-release-5-3.noarch.rpm

2. Install nginx

# yum install nginx

3. You will be asked to install the gpg-key for EPEL. Answer yes

4. Start Nginx

# /etc/init.d/nginx start

5. Check the installation by going to your web server’s default site, either using your ip address or domain name.

Install Kloxo/LxAdmin on CentOS 5.x 32bit

Kloxo installation is fairly easy, however keep in mind this only works on CentOS 32bit.  There is a few bugs in 64bit and I would not recommend it's use.

Let's check what version of CentOS you're on first:

# uname -m
i686 <-- This means it's 32bit.
x86_64 <-- This means it's 64bit

Next let's get the Kloxo installer by running this command:

# wget http://download.lxlabs.com/download/kloxo/production/kloxo-install-master.sh

Now we can install Kloxo:

# ./kloxo-install-master.sh

This will take some time now, after it's completed the below message will appear:

Congratuations. Kloxo has been installed succesfully on your server as master
You can connect to the server at https://<ip-address>:7777 or http://<ip-address>:7778
Please note that first is secure ssl connection, while the second is normal one.
The login and password are 'admin' 'admin'. After Logging in, you will have to change your password to something more secure
We hope you will find managing your hosting with Kloxo refreshingly pleasurable, and also we wish you all the success on your hosting venture
Thanks for choosing Kloxo to manage your hosting, and allowing us to be of service

Now open your Browser and type http://(ip-address):7778 and login with

Username : admin
Password : admin

Follow the instructions to change your password
