{excerpt:hidden=true} How to install and configure the frontend VCL web code. It also describes how to add local accounts to the VCL database, configure LDAP authentication, and set the timezone correctly.{excerpt}

Install & Configure the Web Components

Prerequisites

The following instructions assume these tasks have previously been completed: Apache VCL 2.3 has been downloaded VCL database has been installed and configured

Web Server:

{info}The VCL web frontend may run under other web server platforms capable of running PHP code, but has only been tested to work with Apache HTTP Server.{info}

Required Linux Packages:

Required PHP Modules:

For RHEL / CentOS 5 {tip} yum install httpd mod_ssl php php-gd php-mysql php-xml php-xmlrpc php-ldap -y {tip} For RHEL / CentOS 6 {tip} yum install httpd mod_ssl php php-gd php-mysql php-xml php-xmlrpc php-ldap php-process -y {tip} {info} You may need the optional server rpm repository for the php-process package to add this run the following command: rhn-channel --add --channel=rhel-x86_64-server-optional-6 {info} 1. # Configure the web server daemon (httpd) to start automatically: {tip} /sbin/chkconfig --level 345 httpd on {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

  1. h2. Install the VCL Frontend Web Code

  2. 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

  3. Copy the web directory to a location under the web root of your web

    server and navigate to the destination .ht-inc subdirectory: {tip} cp -r apache-VCL-2.3/web/ /var/www/html/vcl cd /var/www/html/vcl/.ht-inc

  4. Copy secrets-default.php to secrets.php:

    {tip} cp secrets-default.php secrets.php

  5. Edit the secrets.php file:

    {tip} vi secrets.php

  6. * Set the following variables to match your database configuration:

  7. $vclhost

  8. $vcldb

  9. $vclusername

  10. $vclpassword

  11. * Create random passwords for the following variables:

  12. $cryptkey

  13. $pemkey

  14. * Save the secrets.php file

  15. Run the genkeys.sh

    {tip} ./genkeys.sh

  16. Copy conf-default.php to conf.php:

    {tip} cp conf-default.php conf.php

  17. 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}

  18. * 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

  19. Set the owner of the .ht-inc/maintenance directory to the web server

    user (normally 'apache'): {tip}chown apache maintenance{tip}

  20. Open the testsetup.php page in a web browser:

  21. * If you set up your site to be https://my.server.org/vcl/

    open [https://my.server.org/vcl/testsetup.php]

  22. * Debug any issues reported by testsetup.php

  23. h2. Log In to the VCL Website

  24. Open the index.php page in your browser (https://my.server.org/vcl/index.php

    )

  25. * Select Local Account

  26. * Username: admin

  27. * Password: adminVc1passw0rd

  28. Set the admin user password (optional):

  29. Click User Preferences

  30. Enter the current password: adminVc1passw0rd

  31. Enter a new password

  32. Click Submit Changes

  33. h2. Add a Management Node to the Database

  34. Click the Management Nodes link

  35. Click Add

  36. Fill in these required fields:

  37. * 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 , 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}

  38. * IP address - the public IP address of the management node

  39. * SysAdmin Email Address - error emails will be sent to this address

  40. * 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

  41. * End Node SSH Identity Key Files - enter /etc/vcl/vcl.key unless you

    know you are using a different SSH identity key file

  42. Optionally, fill in these fields:

  43. * 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.

  44. * 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

  45. Click Confirm Management Node

  46. Click Submit

  47. Click the Management Nodes link

  48. Select Edit Management Node Grouping

  49. Click Submit
