OpenMeetings is an Apache Foundation project that allows you to deploy a server for Internet conferencing. But it’s not only limited to that, but it also provides chat and file transfer.

Also, OpenMeetings is released as open-source and because it is built in Java it can be run on many different operating systems. With this, quality and security are guaranteed because we can manage everything ourselves.

So let’s go for it.

Install OpenMeetings on Ubuntu 20.04 / 18.04

One of the advantages of OpenMeetings is that it’s made in Java with all that that implies. That is, robustness, stability, and that Java is cross-platform so it works on almost any system. So the first step is to install Java.

1.- Install some required packages and Java on Ubuntu 20.04 / 18.04

Before installing Java, it is convenient to install some dependencies first. So open a terminal session or connect to your server and run the following command:

:~$ sudo apt install imagemagick ghostscript libxt6 libxrender1 ffmpeg sox

These packages increase the capabilities of OpenMeetings.

Then we can install Java. The easiest and safest option is to use OpenJDK which is in the Ubuntu repositories. This Open-source implementation of Java is the same but with a more permissive license.

To install it execute the following command:

:~$ sudo apt install openjdk-11-jre

OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1, mixed mode, sharing)

So, you can continue.

2.- Install and configure MariaDB (optional)

This step is optional because Apache OpenMeetings has an integrated database manager. However, it’s a good idea to rely on MariaDB or MySQL.

To install it, use the following command:

:~$ sudo apt install mariadb-server
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following additional packages will be installed:
  galera-3 libaio1 libcgi-fast-perl libcgi-pm-perl libconfig-inifiles-perl libdbd-mysql-perl libdbi-perl libencode-locale-perl libfcgi-perl libhtml-parser-perl

Need to get 24.1 MB of archives.
After this operation, 184 MB of additional disk space will be used.
Do you want to continue? [Y/n]

Then use the mysql_secure_installation script to assign a root password.

And finally, it creates the database and the new user dedicated to OpenMeetings.

:~$ sudo mysql -u root -p
>CREATE DATABASE openmeetingsdb;
> GRANT ALL PRIVILEGES ON openmeetingsdb.* TO 'openmeetings'@'localhost' IDENTIFIED BY 'userpss';
> FLUSH PRIVILEGES;
> exit;

3.- Download OpenMeetings on Ubuntu 20.04 / 18.04

Now we can start downloading OpenMeetings. To do this I’ll go to the /tmp/ folder and from there with the help of the wget command start the download.

:~$ cd /tmp/
:~$ wget http://www-eu.apache.org/dist/openmeetings/4.0.10/bin/apache-openmeetings-4.0.10.tar.gz

At the time of writing this post, the latest stable version is 4.0.10 so, first, check and modify the command.

Then, after downloading it, we have to create a folder where we will decompress the file. In my case, I’ve named it openmeetings.

:~$ mkdir openmeetings

Now, decompress the file and move the folder to /opt/

:~$ sudo tar xvf apache-openmeetings-4.0.10.tar.gz -C openmeetings/
:~$ sudo mv openmeetings /opt/

Now access the folder where it is installed and start the server. It will take a while depending on the computer:

:~$ cd /opt/openmeetings
:~$ sudo sh red5.sh openmeetings

Then we can complete the installation from the program’s web interface.

4.- Install OpenMeeting on Ubuntu 20.04 / 18.04

Now you have to complete the installation from the web interface. To do this, open your favorite web browser and go to the following address:

http://your-server-ip:5080/openmeetings

Of course, it replaces the corresponding value. Or the DNS.

You’ll see the following:

Next, press the “>” button.

Now, you will see the database configuration screen. Select MariaDB /MySQL and type the credentials.

Now, create the admin user and Group. Then press the “>” button.

Then, set up some settings for OpenMeetings.

Now it’s the converters’ turn. To do this, write down the routes for each of them. And then click on the > button.

Keep configuring the software. This time with red5SIP configuration.

The next step is to complete the installation.

If everything went well, you will see the following screen.

So, log in and start to use the application.

So, enjoy it.

Conclusion

Within an organization or educational environment, communication plays an important role. And thanks to OpenMeetings you can deploy a server that allows you to have meetings and chat, manage it and share files. Today you have learned how to install this tool on a Ubuntu 20.04 / 18.04 server.

InoERP is an open source web-based enterprise management system. So, it is built using open source technologies and has a wide range of features suitable for running various kind of businesses. In addition, the application is an ERP (Enterprise Resource Planning) ie a system where you can manage employees, payments, finance, inventory of a company. It is extremely efficient with the use of resources.

So, let us start to install inoERP.

1. Install Apache web server and PHP

inoERP is a web application that runs on a web server, so the first step is to install Apache and PHP.

:~$ sudo apt install apache2 php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-gd php7.2-bcmath php7.2-xml php7.2-cli php7.2-zip

Next, enable Apache to start at the boot system.

:~$ sudo systemctl enable apache2

Now, you have to configure PHP to work with inoERP. Open the PHP configuration file:

:~$ sudo nano /etc/php/7.2/apache2/php.ini

And change the following options:

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = YOUR_TIMEZONE

After that, it is time to test PHP and Apache. To do it, create a file called test.php on the /var/www/html/ folder.

:~$ sudo nano /var/www/html/test.php

So, add the following:

<?php
phpinfo();
?>

Now, open the web browser and go to http://SERVER_IP/test.php and you will see this.

So, Apache and PHP are installed.

2. Install MariaDB

inoERP supports several database handlers, from MariaDB to PostgreSQL through Oracle Database. In this case, I will choose MariaDB.

:~$ sudo apt install mariadb-server

Now, set the root password using the mysql_secure_installation script.

:~$ sudo mysql_secure_installation

Using this script you will not only be able to configure the root password, but also other server configurations. For this example, I will answer Y, N, Y, Y.

Now, create a database and user for inoERP.

:~$ sudo mysql -u root -p
CREATE DATABASE inoerpdb;
GRANT ALL PRIVILEGES ON inoerpdb.* TO 'inoerpuser'@'localhost' IDENTIFIED BY 'inoerppss';
FLUSH PRIVILEGES;
exit;

So, MariaDB is ready.

3. Install inoERP on Ubuntu 18.04

Now we will be able to install it, for it we will use git and thus clone its repository on the Apache web folder.

:~$ sudo apt install git

:~$ cd /var/www/html/
:~$ sudo git clone https://github.com/inoerp/inoERP.git

After that, assign the correct permissions.

:~$ sudo chown -R www-data:www-data /var/www/html/inoERP/
:~$ sudo chmod -R 755 /var/www/html/inoERP/

Then, create a new virtual host for using inoERP.

:~$ sudo nano /etc/apache2/sites-available/inoERP.conf

And add the following:

<VirtualHost *:80>
     ServerAdmin admin@your_domain.com
     DocumentRoot /var/www/html/inoERP/inoerp/www
     ServerName inoerp.osradar.lan
     ServerAlias inoerp.osradar.lan

     <Directory /var/www/html/inoERP/inoerp/www/>
          Options FollowSymlinks
          AllowOverride All
          Require all granted
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined
    
     <Directory /var/www/html/inoERP/inoerp/www/>
            RewriteEngine on
            RewriteBase /
            RewriteCond %{REQUEST_FILENAME} !-f
            RewriteRule ^(.*) index.php [PT,L]
    </Directory>
</VirtualHost>

Then, enable the new virtual host and the rewrite module.

:~$ sudo a2ensite inoERP.conf
:~$ sudo a2enmod rewrite
:~$ sudo systemctl restart apache2

So, complete the installation.

4. Complete the installation

Open your web browser and complete the installation by going to your virtual host. And you will see this.

Now, you have to set the databases credentials.

After that, you can start the installation.

At the end of the installation, go to the login page. User: inoerp and password: inoerp.

And you will see the dashboard.

So, that’s it.

Conclusion

Installing and managing these applications will make your business more orderly and better managed. Therefore, it is good to install inoERP to be more efficient in business processes.

OrangeScrum is a fantastic open source project management software. It is ideal for small and medium-sized companies or work teams that are looking for orders and systematize the steps to carry out the project in question.

With this program, you will be able to plan, start, scale and launch your project in a very orderly way. You can Create and assign tasks with utmost clarity and timelines. Track task progress, contribute to the discussion threads, provide timely updates and track time spent on tasks effortlessly.

So, let’s install OrangeScrum on Ubuntu 18.04 LTS.

1. Upgrade the system

First of all, it is convenient to update the system. This ensures that all security updates are installed.

:~$ sudo apt update && sudo apt upgrade

The consequence of doing this step is that you will have the safety patches installed and your system will be more reliable and safer.

2. Install Apache web server

To install OrangeScrum on Ubuntu 18.04 you need an HTTP web server. There are many options, but the most recommended for this program is Apache web server.

:~$ sudo apt install apache2

Next, enable and start the apache service:

:~$ sudo systemctl enable apache2
:~$ sudo systemctl start apache2

Next, you can check the apache service.

:~$ sudo systemctl status apache2

Now, open your web browser and go to HTTP://IP_SERVER. If you this something like this, then, apache is correctly installed.

Now is PHP’s turn.

3. Install PHP

OrangeScrum is developed in PHP. Specifically in CakePHP. Therefore, it is necessary to install this language and its modules. Here I will also install other packages necessary for OrangeScrum to run smoothly.

:~$ sudo apt install unzip wget php7.2 php7.2-bcmath php7.2-cgi php7.2-cli php7.2-common php-curl php7.2-dba php7.2-enchant php7.2-fpm php7.2-gd php7.2-imap php7.2-intl php7.2-ldap php7.2-mbstring php7.2-mysql php7.2-opcache php-imagick php-memcache php7.2-soap php7.2-tidy php7.2-xml php7.2-zip libapache2-mod-php7.2 xvfb libfontconfig wkhtmltopdf

Then, you have to edit the PHP configuration file.

:~$ sudo nano /etc/php/7.2/apache2/php.ini

In this file, you have to set this options.

post_max_size = 200M
upload_max_filesize = 200M
max_execution_time = 300
memory_limit = 512M
max_input_vars = 5000

Note: To make the process easier, you can press CTRL + W to find exactly the parameter to edit.

Finally, restart apache2.

:~$ sudo systemctl apache2

Now, you can proceed with MariaDB.

4. Install MariaDB

MariaDB is a relational database manager derived from MySQL. To use OrangeScrum correctly you need to install it.

:~$ sudo apt install mariadb-server

Next, you can set a root password with mysql_secure_installation script. You can also configure other things.

:~$ sudo mysql_secure_installation

After defining the root password, you will be asked other questions. I answered N, N, Y, Y.

Next, you have to create the Database and user for OrangeScrum.

:~$ sudo mysql -u root -p
CREATE DATABASE orangescrum;
GRANT ALL PRIVILEGES ON orangescrum.* TO 'orangescrumuser'@'localhost' IDENTIFIED BY 'orangescrumbpss';
FLUSH PRIVILEGES;
exit;

Next, create a file to disable strict mode for MariaDB.

:~$ sudo nano /etc/mysql/conf.d/disable_strict_mode.cnf

And add the following:

[mysqld]
sql_mode="IGNORE_SPACE,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Finally, restart MariaDB.

:~$ sudo systemctl restart mariadb

And that’s all for MariaDB.

5. Install OrangeScrum

Now, you can install OrangeScrum. However, first download it.

:~$ cd /tmp
:~$ wget https://www.orangescrum.org/free-download/418ae4d8ef1309695804a7837cd4fc65/ubuntu18-php7 -O orangescrum-ubuntu18-php7.zip

Once the installation is complete, decompress the file.

:~$ unzip orangescrum-ubuntu18-php7.zip

Next, copy the folder to the Apache document root on /var/www/html/

:~$ sudo cp -r orangescrum-orangescrum-ubuntu18-php7 /var/www/html/orangescrum-master

Change the directory to orangescrum-master.

:~$ cd /var/www/html/orangescrum-master

Now, copy the orangeScrum database to the local instance. This is necessary to initialize the database.

:~$ sudo mysql -u orangescrumuser -p orangescrumdb < database.sql

Then, it is necessary to place the MariaDB credentials in the database.php file of OrangeScrum.

:~$ sudo nano app/Config/database.php

And put your credentials.

class DATABASE_CONFIG {

public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'login' => 'orangescrumuser',
'password' => 'password',
'database' => 'orangescrumdb',
'prefix' => '',
'encoding' => 'utf8',
);
}

Obviously, replace whatever you have to replace. For example, the password.

Next, it is necessary to set the credentials to the SMTP email server.

:~$ sudo nano app/Config/config.ini.php

And put your information.

Change the owner of the folder. Next, change the permissions.

:~$ sudo chown -R www-data:www-data /var/www/html/orangescrum-master/
:~$ sudo chmod -R 775 /var/www/html/orangescrum-master/

And enable the PHP and Apache modules. Finally, restart apache.

:~$ sudo phpenmod mbstring
:~$ sudo a2enmod rewrite
:~$ sudo a2enmod headers
:~$ sudo systemctl restart apache2

Now, you have the complete the installation on the web browser.

6. Accessing to the Web Interface

The last step is to access the web interface through the web browser. To perform the Login process.

Go to HTTP://IP_SERVER/orangescrum-master/

Create the user and then log in.

Then, you will see this.

And that’s it.

Conclusion

In any organization it is necessary to have a planning before starting a large project or a more basic one. So, OrangeScrum emerges as a very appealing alternative for small and medium enterprises.
