## *Prerequisites*

The following instructions assume these tasks have previously been
completed:

* *libmcrypt* \- Encryption algorithms library (this requirement can be
removed with a [patch](vcl:patch-to-remove-mcrypt-dependency.html)
)

<a name="VCL2.3WebCodeInstallation-RequiredPHPModules:"></a>

{tip}
1. # Start the web server daemon:
{tip}
/sbin/service httpd start
{tip}
1. # If SELinux is enabled, run the following command to allow the web server
to connect to the database:
{tip}
/usr/sbin/setsebool \-P httpd_can_network_connect=1
{tip}
1. # If the iptables firewall is being used, port 80 and 443 should be opened
up:
{tip}vi /etc/sysconfig/iptables{tip}

    -A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT
    -A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 443 -j ACCEPT

{tip}
service iptables restart
{tip}
  
  
1. h2. Install the&nbsp;VCL Frontend Web Code
1. # If you have not already done so, download and extract the source files
on the web server:
{tip}
wget --trust-server-names
'{nolink:http://vcl.apache.org/downloads/download.cgi?action=download&filename=%2Fvcl%2Fapache-VCL-2.3.tar.bz2}'
tar \-jxvf apache-VCL-2.3.tar.bz2
{tip}
1. # Copy the *web* directory to a location under the web root of your web
server and navigate to the&nbsp;destination&nbsp;*.ht-inc* subdirectory:
{tip}
cp \-r apache-VCL-2.3/web/ /var/www/html/vcl
cd /var/www/html/vcl/.ht-inc
{tip}
1. # Copy *secrets-default.php* to *secrets.php*:
{tip}
cp secrets-default.php secrets.php
{tip}
1. # Edit the *secrets.php* file:
{tip}
vi secrets.php
{tip}
1. #* Set the following variables to match your database configuration:
1. #** *$vclhost*
1. #** *$vcldb*
1. #** *$vclusername*
1. #** *$vclpassword*
1. #* Create random passwords for the following variables:
1. #** *$cryptkey*
1. #** *$pemkey*
1. #* Save the secrets.php file
1. # Run the *genkeys.sh*
{tip}
./genkeys.sh
{tip}
1. # Copy *conf-default.php* to *conf.php*:
{tip}
cp conf-default.php conf.php
{tip}
1. # Modify *conf.php* to match your site
{tip}vi conf.php{tip}
{info}Modify every entry under *"Things in this section must be modified"*.
Descriptions and pointers for each value are included within
conf.php.{info}
1. #* *COOKIEDOMAIN* \- set this to the domain name your web server is using
or leave it blank if you are only accessing the web server by its IP
address
1. # Set the owner of the *.ht-inc/maintenance* directory to the web server
user (normally 'apache'):
{tip}chown apache maintenance{tip}
1. # Open the *testsetup.php* page in a web browser:
1. #* If you set up your site to be [https://my.server.org/vcl/](https://my.server.org/vcl/)
 open [https://my.server.org/vcl/testsetup.php]
1. #* Debug any issues reported by testsetup.php
1. h2. Log In to the VCL Website
1. # Open the index.php page in your browser ([https://my.server.org/vcl/index.php](https://my.server.org/vcl/index.php)
)
1. #* Select *Local Account*
1. #* Username: *admin*
1. #* Password: *adminVc1passw0rd*

1. ## Click *User Preferences*
1. ## Enter the current password: *adminVc1passw0rd*
1. ## Enter a new password
1. ## Click *Submit Changes*
1. h2. Add a Management Node to the Database
1. # Click the *Management Nodes* link
1. ## Click *Add*
1. ## Fill in these required fields:
1. ##* *Hostname -* The name of the management node server. This value
doesn't necessarily need to be a name registered in DNS nor does it need to
be the value displayed by the Linux _hostname_ command. For example, if you
are installing all of the VCL components on the same machine you can set
this value to _localhost_.
{info}Take note of the value you enter for Hostname. In a later step
performed during the [management node installation](vcl:vcl-2.3-management-node-installation.html)
, the value enter for Hostname must match the value you enter for FQDN in
the /etc/vcl/vcld.conf file on the management node.{info}
1. ##* *IP address* \- the public IP address of the management node
1. ##* *SysAdmin Email Address* \- error emails will be sent to this address
1. ##* *Install Path* \- this is parent directory under which image files
will be stored - only required if doing bare metal installs or using VMWare
with local disks
1. ##* *End Node SSH Identity Key Files* \- enter /etc/vcl/vcl.key unless you
know you are using a different SSH identity key file
1. ## Optionally, fill in these fields:
1. ##* *Address for Shadow Emails* \- End users are sent various emails about
the status of their reservations. If this field is configured, copies of
all of those emails will be sent to this address.
1. ##* *Public NIC configuration method* \- this defaults to Dynamic DHCP -
if DHCP is not available for the public interface of your nodes, you can
set this to Static. Then, the IP configuration on the nodes will be
manually set using Public Netmask, Public Gateway, Public DNS Server, and
the IP address set for the computer under Manage Computers
1. # Click *Confirm Management Node*
1. # Click *Submit*
1. # Click the *Management Nodes* link
1. ## Select *Edit Management Node Grouping*
1. ## Click *Submit*
1. ## Select the checkbox for your management node
1. ## Click *Submit Changes*
1. h2. Install & Configure phpMyAdmin (Optional):
