Install and configure a corporate Open Source Booking System on Centos 7

In today's business, it is increasingly necessary to share workspaces, labs, tools, and any other type of resources. Making the most of the available resources has become a competitive advantage for modern businesses.

Every company has finite resources, so there is a dispute over the use of these resources by all members, this is the point, the dispute of these resources can cause problems among employees, wear and tear on relationships and unproductivity in the organization.
This discussion seems to be far from the technology, however, to solve these types of problem, many free Softwares are available and in this article, I write about a corporate tool able to help organize the use of resources in a fair and effective way.

Software Overview

Booked is open source software written in PHP and MySQL that helps organizations and groups efficiently manage, record and track resources of any kind. It allows you to create schedules so users can find schedules available for resource use.

Booked allows resources to be distributed fairly through the use of quotas. It also lets you control the use of resources through reserve approvals. An automatic range between the reservations of a resource can also be configured.

Booked includes great enterprise features like support for a lot of languages, web based, mobile first, reporting system, reminders, LDAP, Active Directory, ical files to integrate with e-mail clients, and more.

The Environment

This article covers the Booked installation and basic configuration. This article was written based on the following environment: A Virtual Box VM with CENTOS 7 Minimal, 2GB RAM, 8GB HD and 2 network interfaces (host-only and NAT).

Security

This article does not cover completely this subject who is complex and extensive. It put the focus on the simple S.O. configuration and Booked system configuration.

Preparation

Assuming that you use a fresh installation of Centos 7 Minimal, before to install Booked, run the following command to update the system and install additional packages: 

yum update
Transaction Summary ================================================================================ Install 1 Package Upgrade 39 Packages Total download size: 91 M Is this ok [y/d/N]: y

Install your favorite text editor or use VI. In this article I use VIM, to install it, run the following command:

yum install vim

Install WGET package, run the following command:

yum install wget

Install UNZIP package, run the following command:

yum install unzip

To configure network, run the following command to open the NMTUI (Network Manager Text User Interface) tool and edit the network interfaces and hostname how you wish:

nmtui

After setup of network settings and hostname on CentOS 7, run the following command to apply the changes:

service networks restart

To verify the network information, run the following command:

ip addr

The output look like this:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Disable SELINUX (Security Enhanced Linux) on Centos 7, edit the following config file:

vim /etc/selinux/config
"/etc/selinux/config" 14L, 547C# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are prootected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

Change the value enforcing of directive SELINUX to disabled, save the file and reboot the server.

To check the status of SELinux on Centos 7, run the following command:

getenforce

The output must be:

Disabled

To disable FirewallD on Centos 7, run the following commands:

systemctl disable firewalld
systemctl stop firewalld

To check firewall status on Centos 7, run the following command:

systemctl status firewalld

Install MariaDB, Apache, and PHP on Centos 7

To install MariaDB on Centos 7, run the following command:

yum -y install mariadb-server

To start MariaDB, run the following command:

systemctl start mariadb

To increase the security of MariaDB, run the following command:

/usr/bin/mysql_secure_installation

Setup the options according to the following output or use your own preferences:

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):<Press Enter>

OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] <Press Y>

Setup root password:

New password: *******
Re-enter new password: ******* 
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] <Press Y>

... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] <Choose acording your needs>

... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] <Press Y>


- Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] <Press Y>

... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Setup MariaDB to start up automatically with the Centos 7:

systemctl enable mariadb.service

To install Apache, run the following command:

yum install httpd

To start Apache, run the following command:

systemctl start httpd.service

Setup Apache to start up automatically with the Centos 7:

systemctl enable httpd.service

To test Apache, in your web browser, type the IP addres of your server. If every thing is all rigth you can see a test page:

To install PHP, run the following command:

yum install php php-mysql

Restart Apache, run the following command:

systemctl restart httpd.service

To test PHP create a file phpinfo.php inside of /var/www/html directory with the following content:

<?php phpinfo(); ?>

Now you can access the phpinfo.php through the browser with the following URL: http://[your-ip-addres]/phpinfo.php. If everything is ok, you can see the following page:

Setup database through the terminal

Access the MariaDB through the terminal and create the database bookedscheduler and the user booked_user with rights enough to manage this database. Run the following commands to do through terminal: 

 mysql -u root -p

Create bookedscheduler database:

MariaDB [(none)]> create database bookedscheduler;

Create booked_user on MariaDb:

CREATE USER 'booked_user'@'localhost' IDENTIFIED BY 'your_password';

Grant permissions to user  booked_user to bookedscheduler database:

GRANT ALL PRIVILEGES ON database.bookedscheduler TO 'booked_user'@'localhost';

Import Booked database schema and data, from the /var/www/html/booked/database_schema/ directory, the following sql files must be imported, create_schema.sql and create-data.sql: 

 mysql -u root -p bookedscheduler < create-schema.sql
 mysql -u root -p bookedscheduler < create-data.sql

Setup database through the PHPMyAdmin

Install PHPMyAdmin on Centos 7 (opitional)

PHPMyAdmin is a tool to manage mysql (mariaDB) databases in a friendly way through a browser. To install phpmyadmin automatically, you need to install the Epel repository, run the following command:

yum install epel-release

Now you can run the following command:

yum install phpmyadmin

After the PHPMyAdmin installation, we need to configure it. First of all, make a copy of config file and edit the phpMyAdmin.conf file in /etc/httpd/conf.d/:

cp /etc/httpd/conf.d/phpMyAdmin.conf /etc/httpd/conf.d/phpMyAdmin.conf.old
vim /etc/httpd/conf.d/phpMyAdmin.conf

Change the values according to your network environment, in my case, I changed following lines (17, 25, 34, 42). My config file looks like this:

# phpMyAdmin - Web based MySQL browser written in php
#
# Allows only localhost by default
#
# But allowing phpMyAdmin to anyone other than localhost should be considered
# dangerous unless properly secured by SSL
Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin

<IfModule mod_authz_core.c>
# Apache 2.4

</IfModule>
 <IfModule !mod_authz_core.c>
 # Apache 2.2

</Directory>
<Directory /usr/share/phpMyAdmin/setup/lib/>
 Order Deny,Allow

</Directory>
<Directory /usr/share/phpMyAdmin/setup/frames/>
 Order Deny,Allow

</Directory>
# This configuration prevents mod_security at phpMyAdmin directories from
# filtering SQL etc. This may break your mod_security implementation.
#
#<IfModule mod_security.c>
# <Directory /usr/share/phpMyAdmin/>
# SecRuleInheritance Off
# </Directory>
#</IfModule>

Restart Apache, run the following command:

systemctl restart httpd.service

Now you can access the PHPMyAdmin through the browser with the following URL: http://[your-ip-addres]/phpMyAdmin/

Use your root account and the password previously defined on the MariaDB installation to create the database and user. At the dashboard, select Databases option to create a new database:

Fill the form with the database name and select create.

To import the database data, on the left menu, select the bookedscheduler database, and the Import from PHPMyAdmin dashboard, choose the following files, create-schema.sql (1) and create-data.sql (2), from installation files and import it.

Create the user booked_user with the permissions to manage bookedscheduler database. On the PHPMyAdmin dashboard, select Users and Add:

On the user creation screen, fill the fields with the user database (booked_user), set up a password and select GO at the end of the page:

 

To set up privileges to booked_user on bookedscheduler database, select bookedscheduler from a database list and select Go:

On the privileges screen, select the option Check All and Go:

Installing Booked Scheduler Centos 7

We have two ways to install Booked Scheduler, manual or automatically. This article cover only the manual installation. To install Booked Scheduler on Centos 7, go to /tmp directory and download the source code:

wget https://ufpr.dl.sourceforge.net/project/phpscheduleit/Booked/2.6/booked-2.6.5.zip 

Unzip the file on the /var/www/html directory, run the following command:

unzip booked-2.6.5.zip -d /var/www/html/

Change the permissions of the unzipped file. 

cd /var/www/html/
chown -R apache:apache /booked

Setup the configuration file in /var/www/html/booked/config. Make a copy of the config.dist.php file to config.php and edit the blocks of the configuration file (It is my config file):

cp config.dist.php config.php

Change the values according to our environment, here I present the main settings to change, and be informed, the email address will be the system admin after the first sign up:
