Centos 6 Webserver

In this article we will install some software that is useful on a webserver based on Centos 6.
For the beginning let us install some packages that will be useful later:

yum install nano wget fetchmail zip unzip bzip2 nmap openssl lynx fileutils ncftp gcc gcc-c++ gd-devel
yum update

Apache

yum install httpd

Set Apache to start at boot:

chkconfig httpd on

You can print installed httpd modules with the command httpd -l:

[root@webserver]# httpd -l
Compiled in modules:
  core.c
  prefork.c
  http_core.c
  mod_so.c

Conf file /etc/httpd/conf/httpd.conf

MySQL + php

yum install mysql-server php php-mysql

Postfix, POP3/IMAP server

Note that default MTA in Centos is sendmail, so if you want to use postfix you should remove sendmail first:

yum remove sendmail
yum install postfix dovecot

Conf file /etc/postfix/main.cf

Ftp

yum install vsftpd

Conf file /etc/vsftpd/vsftpd.conf

Webalizer

yum install webalizer

Conf file is /etc/httpd/conf.d/webalizer.conf
