Chapter 11. Cloning open source virtual servers
The secret to creativity is knowing how to hide your sources.
--Albert Einstein
This chapter describes how to clone and customize the following Linux virtual servers:
► “Creating a virtual Web server” on page 169
► “Creating a virtual LDAP server” on page 173
► “Creating a virtual file and print server” on page 178
► “Creating a virtual application development server” on page 182
The sections that follow don’t go into the theory nor detail on the four types of servers. Rather,
they are just a reference to get the servers quickly installed and configured. There are many
other resources that go into depth on these types of servers.
11.1 Creating a virtual Web server
The example in this section uses the LINUX01 user ID to create a virtual Web server. You
should have a vanilla virtual server cloned to the user ID LINUX01 as described in Chapter 9,
“Configuring RHEL 6 for cloning” on page 145.
11.1.1 Installing Apache RPMs
To accomplish this task, perform the following steps:
► SSH into the IP address of the new LINUX01 server. Install the following Apache RPMs
with the yum -y install command. The -y flag prevents the “Is this OK” question:
# yum -y install httpd httpd-manual
...
Installed:
httpd.s390x 0:2.2.15-5.el6 httpd-manual.noarch 0:2.2.15-5.el6
Dependency Installed:
apr.s390x 0:1.3.9-3.el6 apr-util.s390x 0:1.3.9-3.el6
