install_irc_server_on_centos6

// Setting up an IRC server on Cent 6

// Create a user and group for this guy
$ groupadd ircadmin && useradd -m -g ircadmin -s /bin/bash ircadmin

// Make a working directory (/var/source/)
mkdir source && cd source

// Grab the latest versions of Anope and UnrealIRCd
$ wget http://www.unrealircd.com/downloads/Unreal3.2.9.tar.gz http://downloads.sourceforge.net/project/anope/anope-stable/Anope%201.8.7/anope-1.8.7.tar.gz

// Make great extractions
$ tar zxf Unreal3.2.9.tar.gz
$ tar zxf anope-1.8.7.tar.gz

// Configure (IMPORTANT: if you get any error like: configure: error: no acceptable C compiler found in $PATH ) type: yum install gcc
$ ./Config

// Now on your screen you will see configuration like:
Do you want to enable the server anti-spoof protection?
[Yes] ->
What directory are all the server configuration files in?
[/var/Unreal3.2] ->
What is the path to the ircd binary including the name of the binary?
[/var/Unreal3.2/src/ircd] ->
What should the default permissions for your configuration files be? (Set this to 0 to disable)
It is strongly recommended that you use 0600 to prevent unwanted reading of the file
[0600] ->
Do you want to support SSL (Secure Sockets Layer) connections?
[No] ->
Do you want to enable IPv6 support?
[No] ->
Do you want to enable ziplinks support?
[No] ->
Do you want to enable remote includes?
This allows stuff like this in your configuration file:
include “http://www.somesite.org/files/opers.conf”;
[No] ->
Do you want to enable prefixes for chanadmin and chanowner?
This will give +a the & prefix and ~ for +q (just like +o is @)
Supported by the major clients (mIRC, xchat, epic, eggdrop, Klient,
PJIRC, irssi, CGI:IRC, etc.)
This feature should be enabled/disabled network-wide.
[Yes] ->
What listen() backlog value do you wish to use?  Some older servers
have problems with more than 5, others work fine with many more.
[5] ->
How far back do you want to keep the nickname history?
[2000] ->
What is the maximum sendq length you wish to have?
[3000000] ->
How many buffer pools would you like?
This number will be multiplied by MAXSENDQLENGTH.
[18] ->
How many file descriptors (or sockets) can the IRCd use?
[1024] ->
