This guide assumes that you have the following:
- You have already installed your CentOS 7 or Ubuntu 14 Operating system
- You have 10GB of free space (a 24GB hard disk should hold everything)
- You have forwarded the network port to the server

Notes:
- Unless otherwise specified, all steps apply to CentOS 7 and Ubuntu 14
- Things that start with the # sign are comments, bash wont execute them
- This guide will not work for CentOS 6 because of GLIBC issues

## Please run this as a user other than root.

## Packge Install CentOS 7:
yum -y install wget
yum -y install glibc.i686
yum -y install libgcc_s.so.1

## Package Install Ubuntu 14
sudo apt-get install wget
sudo apt-get install lib32gcc1

## Install SteamCMD Ubuntu 14 and Centos 7
wget -O ~/steamcmd_linux.tar.gz https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz
tar -xvzf /root/steamcmd_linux.tar.gz
mkdir /insurgency
~/steamcmd.sh +login anonymous +force_install_dir "/insurgency" +app_update 237410 +quit

## CentOS 7
firewall-cmd --zone=public --add-port=27015/tcp --permanent
firewall-cmd --zone=public --add-port=27015/udp --permanent
firewall-cmd --reload


## Ubuntu 14
## (not neccesary)

cp /insurgency/insurgency/cfg/server.cfg.example /insurgency/insurgency/cfg/server.cfg
vi /insurgency/insurgency/cfg/server.cfg
# Please edit this file to change your RCON Password

echo export LD_LIBRARY_PATH=/insurgency:/insurgency/bin > /insurgency/insurgency_start.sh
echo /insurgency/srcds_linux -console -port 27015 +map market_coop +maxplayers 8 >> /insurgency/insurgency_start.sh
sh /insurgency/insurgency_start.sh

A good generic guide on how install Insurgency Server, which includes a good server.cfg example: https://developer.valvesoftware.com/wiki/Insurgency_2014_Dedicated_Server

If you have a windows server, Arc has an excellent guide: http://steamproxy.net/sharedfiles/filedetails/?id=345661185

I welcome any feedback on this guide. I hope this is helpful.

For you techies out there. This can be used to automaticly install your server with no user input (just fill in ip addresses, passwords, etc below wherever I have ##). KVM is a very usefuly and free hypervisor and can allow you spin up virtual servers at home with ease. My main KVM server has httpd installed on is, hosting the kickstart files. This allows me to re-create my insurgency server from scratch with a single command.
