OCSInventory allows you to collect hardware and software inventory from all active devices on the network, such as computers, switches, routers, network printers and unattended devices. It Supports for multiple operating systems, including Microsoft Windows, Linux, * BSD, Sun Solaris, IBM AIX, HP-UX, MacOS X. It has the ability to support Plugins and integrates seamlessly with GLPI.

So, let us start.

Install OCS Inventory Server on CentOS 8

Prerequisites

Before starting with the installation of the OCS Inventory, it is necessary to install and configure some applications.

So, open a terminal or SSH connection and add the EPEL and REMI repositories.

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

Install the dnf-utils package to use other dnf features.

dnf install dnf-utils

And enable the powertools repository which we will need as well:

dnf config-manager --set-enabled powertools

Now yes, install Apache, MariaDB, and PHP along with some modules that are dependencies of OCS Inventory

dnf install httpd mariadb-server php php php-curl php-zip php-gd php-soap php-xml php-mbstring php-fpm unzip curl

Next, start the httpd, php-fpm and MariaDB services

systemctl start httpd mariadb php-fpm
systemctl enable httpd mariadb php-fpm

Of course, you have to configure MariaDB with the mysql_secure_installation script to define a password for the root user.

mysql_secure_installation

Remove anonymous users? Y
Disallow root login remotely? Y
Remove test database and access to it? Y
Reload privilege tables now? Y

Then open the ports in the firewall necessary for Apache to work.

firewall-cmd --add-port=80/tcp --zone=public --permanent
success
firewall-cmd --add-port=443/tcp --zone=public --permanent
success
firewall-cmd --reload
success

Now create the database, the user, and its permissions so that it can be used by OCS Inventory

mysql -u root -p

CREATE DATABASE ocsweb;
GRANT ALL ON ocsweb.* TO 'ocs'@'localhost' IDENTIFIED BY 'ocspss';
FLUSH PRIVILEGES;
Exit;

After this, we can start the installation.

Download and install OCS Inventory

Now we will be able to perform the installation. First, install the PERL modules that the system has:

dnf install make gcc perl-Archive-Zip perl-Compress-Zlib perl-DBD-MySQL perl-DBI perl-Mojolicious perl-Net-IP perl-Plack perl-SOAP-Lite perl-Switch perl-XML-Entities perl-XML-Simple perl-Apache-DBI perl-Digest-SHA1 perl-Apache2-SOAP

Next, add the OCS Inventory repository for CentOS 8

dnf install https://rpm.ocsinventory-ng.org/ocsinventory-release-latest.el8.ocs.noarch.rpm

And finally, install it by running:

dnf install ocsinventory

Once installed, it is necessary to copy the sample database into the database we have created:

mysql -u root -p ocsweb < /usr/share/ocsinventory-reports/ocsreports/files/ocsbase.sql

Now, enable the rewrite modules in Apache by editing its configuration file:

nano /etc/httpd/conf/httpd.conf

At the end of the document, add the following:

LoadModule rewrite_module modules/mod_rewrite.so

Apply the changes, restarting the Apache service:

systemctl restart httpd

Now we can complete the installation.

Using OCS Inventory

The next step is to open your preferred web browser and access http://your-server/ocsreports/install.php.

Note: replace your-server with the IP address of the server or domain.

You should see the database configuration screen. Type the parameters.

So, You will then see a screen informing you that the database connection was successful.

Next, update the database version by clicking on the Perform the update button and you will see this message

Then the login screen

Then, Log in with the default credentials admin/admin and now you have the OCS Inventory server ready.

Conclusion

So, OCSInventory is a great application that we can take full advantage of in an organization, whether it is small or large. Well, today you have learned to install it on a computer with CentOS 8.

The post How to install OCS Inventory Server on CentOS 8? appeared first on Linux Windows and android Tutorials.

Let’s go for it.

Install OCSInventory agent on Ubuntu 18.04 / Linux Mint 19

First of all, the system needs to be upgraded.

Open a terminal session and run the following command:

:~$ sudo apt update
:~$ sudo apt upgrade

This step is vital for the agent to do the job properly. It also allows him to gather more and better information from the computer.

This client is also written in Perl language, so we have to install some libraries first:

:~$ sudo apt install libmodule-install-perl dmidecode libxml-simple-perl libcompress-zlib-perl libnet-ip-perl libwww-perl libdigest-md5-perl libdata-uuid-perl

Then, we can install the OCSInventory agent in two ways.

The first is by manually compiling the source code. This option has the advantage that we can get the latest version of it, but it is something more complex and in a business environment may not be suitable.

On the other hand, the program is available from official repositories. This method sacrifices a little bit of the novelties for the sake of stability and ease of installation.

To install it, we will use the second option, therefore, run the following command

:~$ sudo apt install ocsinventory-agent

So, we need to configure it.

Configuring the OCSInventory agent

During installation, a customer configuration screen will be displayed. This first screen asks where the server is.

If the agent is being installed in the same computer where the server is, choose the first option. If not, choose the second one.

Then, you will see another screen where you have to indicate the IP address or the hostname of the computer where the OCSInventory server is installed.

Then the installation will be finished.

In case you make a mistake in this step, do not worry, you can always rectify it by modifying the file /etc/ocsinventory/ocsinventory-agg.

The synchronization with the server is done via crontab daily. However, we can force this synchronization with the following command:

:~$ sudo ocsinventory-agent --server [server]

You’ll see something like this:

Now, access your OCSInventory server and you’ll see that it’s been added correctly.

And that’s it. Now we invite you to explore all the new possibilities with this tool.

Conclusion

Thanks to OCSInventory for the inventory work, and it makes it much easier. And always with a fairly high degree of accuracy. So today, you have learned how to install the OCSInventory agent on Ubuntu 18.04 and Linux Mint 19. So all that remains is for you to get the most out of the tool.

It Supports for multiple operating systems, including Microsoft Windows, Linux, * BSD, Sun Solaris, IBM AIX, HP-UX, MacOS X. It has the ability to support Plugins and integrates seamlessly with GLPI.

So, let us start.

Install OCSInventory on Debian 10

1.- Install LAMP and required modules

OCSInventory requires all LAMP components to function fully. Therefore, this is what we have to do first. So read our post about it:

How to install LAMP on Debian 10?

However, you also have to install other Apache-related modules that are not in the LAMP on Debian 10 post:

:~$ sudo apt install libapache2-mod-php libapache2-mod-perl2 libapache-dbi-perl libapache-db-perl 

On the other hand, other PHP modules have to be installed as dependencies of the OCSInventory web interface.

:~$ sudo apt install php-soap php-curl php-json php-xml php-mbstring php-gd php-pclzip php-xmlrpc

Once all these modules are installed together with the LAMP stack, we can continue.

2.- Installing the development tools on Debian 10

At some point during the installation, some packages are required to compile and build other packages from the source code.

Fortunately, these packages are available from the official Debian repositories. This makes installation easy.

Just run the following commands:

:~$ sudo apt install cmake gcc make build-essential make

The installation will take some time, depending on the computer you have.

3.- Creating a new database for OCSInventory

As I mentioned earlier, OCSInventory requires a database manager. This has to be MySQL or MariaDB.

As a member of the LAMP stack, we already have it installed and configured, but it is convenient to make a database dedicated to OCSInventory. Also, it is a good idea to create a new user for the application.

First access the MariaDB shell:

:~$ sudo mysql -u root -p

And then, it creates the new database, the user and the permissions on it.

> CREATE DATABASE ocsdb;
> GRANT ALL PRIVILEGES ON ocsdb.* TO 'ocsuser'@'localhost' IDENTIFIED BY 'ocspassword';
> FLUSH PRIVILEGES;
exit;

Now we can continue.

4.- Install some Perl modules

The OCSInventory server is made with PERL. That’s why you have to install many modules of this language.

First, we will install some of them using APT.

:~$ sudo apt install perl libnet-ip-perl libxml-simple-perl libarchive-zip-perl libxml-simple-perl libcompress-zlib-perl libdbi-perl libdbd-mysql-perl libnet-ip-perl libsoap-lite-perl libio-compress-perl libapache-dbi-perl libapache2-mod-perl2 libapache2-mod-perl2-dev libdbd-mysql-perl

And then, we’ll use a tool to do it manually:

:~$ sudo cpan install XML::Entities Apache2::SOAP Net::IP Apache::DBI Mojolicious Switch Plack::Handler Archive::Zip

The installation will take a while, so be patient. When it finishes we will be able to download the application.

5.- Download and install OCSInventory on Debian 10

After installing so many dependencies and libraries, we can now download and install OCSInventory. To do this we will use the wget command. At the time of writing this post, the latest stable version is 2.6.

So, let’s go for it.

:~$ wget -c https://github.com/OCSInventory-NG/OCSInventory-ocsreports/releases/download/2.6/OCSNG_UNIX_SERVER_2.6.tar.gz -O ocs.tar.gz

Now proceed to decompress it.

:~$ tar -xvzf ocs.tar.gz

Then go to the generated folder and edit the installation script to add our database credentials.

:~$ cd OCSNG_UNIX_SERVER_2.6/
:~$ sudo nano setup.sh

And leave it the following way:

DB_SERVER_HOST="localhost"
DB_SERVER_PORT="3306"
DB_SERVER_USER="ocsuser"
DB_SERVER_PWD="ocspassword"

Remember, you have to place the data from the database you have defined. These are the ones I used as an example.

So, save the changes and close the file. Now we have to run the installation script.

:~$ sudo ./setup.sh

The screen outputs of the script are quite long. But they are easily understandable if you read it carefully. Anyway, what the script asks you to do is to set up various configurations. Many of them you just have to press the enter key and set the default configuration.

Of course, the script will look for the Perl dependencies we have in the system.

And the optional modules:

Once the whole script is finished and if everything has gone well, you will see the following message:

6.- Configuring OCSInventory on Debian 10

Even though the installation has been successfully completed there are still some extra settings to be made.

First enable the newly installed Apache settings for OCSInventory.

:~$ sudo ln -s /etc/apache2/conf-available/ocsinventory-reports.conf /etc/apache2/conf-enabled/ocsinventory-reports.conf

:~$ sudo ln -s /etc/apache2/conf-available/z-ocsinventory-server.conf /etc/apache2/conf-enabled/z-ocsinventory-server.conf

These settings are for the OCSInventory web interface to be properly processed by Apache2.

Then, change the execution permissions of the OCSInventory folder so that there are no problems with the graphical interface.

:~$ sudo chown -R www-data:www-data /var/lib/ocsinventory-reports/

After that, you have to write the database parameters to another configuration file:

:~$ sudo nano /etc/apache2/conf-available/z-ocsinventory-server.conf

As in the previous configuration file, you have to write the name of the database, the MariaDB user and the password.

Save the changes and close the file.

After that, restart Apache.

:~$ sudo systemctl restart apache2

Now all you have to do is complete the installation through the web interface.

To do this open your favorite web browser and go to http://your-server/ocsreports/ and you will see a screen where you have to place your MariaDB credentials.

Then, the installation will begin and if everything has gone well, you will see the following image:

There you will see the default credentials which are user:admin and password:admin.

Now you will see the Login screen:

Once you have logged in you will see the following:

There you go. OCSInventory is ready for use. Now we need to install the agents on the computers.

Conclusion

OCSInventory is a great application that we can take full advantage of in an organization, whether it is small or large. Well, today you have learned to install it on a computer with Debian 10.

Inventories are tangible goods held for sale in the ordinary course of business or to be consumed in the production of goods or services for subsequent marketing.

It’s usually a tedious process carried out manually, but thanks to the efforts of some developers, it’s possible to do it automatically and efficiently with OCSInventory.

OCSInventory allows you to collect hardware and software inventory from all active devices on the network, such as computers, switches, routers, network printers and unattended devices. It Supports for multiple operating systems, including Microsoft Windows, Linux, * BSD, Sun Solaris, IBM AIX, HP-UX, MacOS X. It has the ability to support Plugins and integrates seamlessly with GLPI.

Let’s install it!!

First of all we must be root users. We open a terminal and write:

sudo -i

After entering the password we will be root users. Then we installed LAMP Stack.

apt install apache2 php7.2 libapache2-mod-php7.2 php7.2-cli php7.2-common php7.2-cgi mariadb-server mariadb-client php7.2-mysql mariadb-common

Once the installation of the packages is finished we will have a basic web server. Now we proceed to install basic compilation packages.

 apt install linux-headers-$(uname -r) build-essential

Next we must install some perl modules needed.

apt install libxml-simple-perl libcompress-raw-zlib-perl libdbi-perl libdbd-mysql-perl libapache-dbi-perl libnet-ip-perl libsoap-lite-perl

Now we write:

cpan -i XML::Entities

We install other necessary php modules.

apt install php7.2-gd php-pclzip

We now proceed to download the OSCInventory.

wget https://github.com/OCSInventory-NG/OCSInventory-ocsreports/releases/download/2.4.1/OCSNG_UNIX_SERVER_2.4.1.tar.gz

Now we unzip the archive.

tar -xvzf OCSNG_UNIX_SERVER_2.4.1.tar.gz

Now we rename the folder, and move it to our apache root directory:

mv OCSNG_UNIX_SERVER_2.4.1 /var/www/html/OCS

Before starting the installation, we installed other necessary php modules.

apt install php7.2-soap php7.2-curl php7.2-xml php7.2-xmlrpc

Now we enter the directory and run the setup.sh script

cd /var/www/html/OCS

and:

sh setup.sh

Running it will ask us many questions about configuration file locations, executable files and check the installed PERL modules. In the end, if everything went well, we should get the message that the installation was successful.

Before running its web interface, we must copy the apache configuration that the installer creates as a new apache site.

a2enconf ocsinventory-reports

a2enconf z-ocsinventory-server

Finally, we make sure we have permissions on the /var/lib/ocsinventory-reports/ folder and we restart apache.

<strong>chown -R www-data:www-data /var/lib/ocsinventory-reports/
chmod 755 -R /var/www/html/OCS/*
systemctl restart apache2
</strong>

Accessing the web interface

Now we can access the web interface from our browser:

http://localhost/OCS/ocsreports

Note: Remember that the path might be different, so it is important to be careful about assigning folder names.

As we can notice, we skip the warning that we can’t build larger 2mb packages, so we must modify that value in the PHP configuration file.

nano /etc/php/7.2/apache2/php.ini

We will modify the parameters: upload_max_filesize and post_max_size

And we restart Apache:

systemctl restart apache2

When accessing again, we notice that the warning continues but 250mb is a suitable value that should not cause problems.

When you click on send, it will take a while to complete the installation and then inform us that we can access with user admin and password admin

By clicking on the link below, we can then log in.

Then when you log in, and check that everything is OK, we must remove the installer. As a recommendation you should change the password for mariadb.

Now we would have to install the agent in each of the computers that we want to inventory.

As a conclusion we can say that OCSInventory is an interesting application in the world of organizations that allows us to have an updated and reliable inventory of all our computer equipment.
