En este post veremos como instalar OCS Inventory en CentOS 8 para luego inventariar los equipos y dispositivos automáticamente. Para ello debemos cumplir con unos pre requisitos:
- Tener las ultimas actualizaciones del SO
- Tener instalado Apache con PHP y de base de datos MariaDB o MySQL
- Tener instalados los paquetes utilizados (nano, tar, wget)
- Tener conexión a internet en el servidor
Para iniciar instalamos el siguiente paquete:
yum install mod_ssl openssl
Luego creamos una carpeta llamada ssl en la ruta del apachemkdir /etc/httpd/ssl
Para luego crear un certificado en la carpeta que creamosopenssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout /etc/httpd/ssl/apache.key -out /etc/httpd/ssl/apache.crt
Creamos una fuerte clave, para luego agregarla al certificado
openssl dhparam -out /etc/httpd/ssl/dhparam.pem 2048
cat /etc/httpd/ssl/dhparam.pem | tee -a /etc/httpd/ssl/apache.crt
Luego editamos el archivo ssl.conf para configurar la ruta de los certificado que creamos y la ruta de la aplicación con el puerto 443
nano /etc/httpd/conf.d/ssl.conf
Luego configuramos la ruta en los siguientes parametros SSLCertificateFile y SSLCertificateKeyFile para asignarle la ruta al nuevo certificado y la ruta a la nueva llave
Validamos que los puertos http y https estén abiertos en el firewall. en caso que no debemos abrirlos, en mi caso ya están abiertos.
Luego instalamos los siguientes paquetes en el siguiente orden.
dnf install php php-domxml php-gd php-imap php-ldap php-mbstring php-mysqlnd php-opcache php-pdo php-pear php-pecl-apcu php-pecl-zip php-soap php-xmlrpc php-gd php-xml php-zip php-fpm php-bcmath php-intl -y
dnf -y install @httpd mod_perl
dnf -y install https://rpm.ocsinventory-ng.org/ocsinventory-release-latest.el8.ocs.noarch.rpm
dnf config-manager --set-enabled PowerTools
dnf install -y 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
Luego de haber instalado los paquetes anteriores, procedemos a descargar OCS Inventory
Lo descomprimimos y acedemos a la carpeta, para finalmente correr el setup.
tar xzf OCSNG_UNIX_SERVER_2.7.tar.gz
cd OCSNG_UNIX_SERVER_2.7/sh setup.sh
Cuando ejecutemos el setup nos saldra unas opciones las cuales les muestro a continuación que seleccionar.

If you encounter error while running OCS Inventory NG Management server,
we can ask you to show us its content !
DON'T FORGET TO RESTART APACHE DAEMON !
Enjoy OCS Inventory NG ;-)
Luego de la instalación configuraremos los siguientes parámetros en el archivo php.ini
sudo nano /etc/php.ini
upload_max_filesize = 10M
post_max_size = 10M
max_execution_time = 300
max_input_time = 300
memory_limit = 512M
Y reiniciamos los servicios de Apache y PHP
systemctl restart httpd php-fpm
Luego de reiniciar los servicios pasamos a modificar los siguientes archivos, a los cuales le vamos a indicar el nombre de la bd, user y password.
nano /etc/httpd/conf.d/z-ocsinventory-server.conf
nano /etc/httpd/conf.d/zz-ocsinventory-restapi.conf
nano /usr/share/ocsinventory-reports/ocsreports/dbconfig.inc.php
Luego procedemos asignarle permisos a la carpeta de OCS Inventory
chmod -R 766 /usr/share/ocsinventory-reports
chown -R apache:apache /usr/share/ocsinventory-reports
chown -R apache:apache /var/lib/ocsinventory-reportschcon -R -t httpd_sys_rw_content_t /usr/share/ocsinventory-repo
Y reiniciamos los servicio de Apache, PHP y MySQL
systemctl restart httpd mysqld php-fpm
Luego debemos acceder con la siguiente ruta para continuar con la instalación, en la cual indicaremos los datos de conexion (bd, user, password, y host) y le damos enviar.
http://server-hostname-or-IP/ocsreports
Si por algún motivo les sale error en la conexión la BD como el siguiente.
"ERROR: Problema de conexión MySql 1231 Variable 'sql_mode' can ' t se establezca en el valor de 'NO_AUTO_CREATE_USER' ".
Lo podremos corregir eliminando la variable sql_mode configurada como "NO_AUTO_CREATE_USER" en 5 archivos diferentes de .php dentro de la carpeta OCS. Les dejo la ruta para que les sea mas facil encontrarlos
./install.php
./backend/require/connexion.php
./plugins/main_sections/ms_server_infos/ms_server_infos.php
./require/function_commun.php
./require/html_header.php
Ya luego les aparecerá esta pantalla, solo seleccionamos OCS-NG Inventory Installation
Damos clic al boton Perform the update
Y clic aquí para ingresar a la GUI de OCS-NG
Para ingresar las credenciales iniciales son user:admin y password:admin
Ya por ultimo nos indicar eliminar el archivo install.php en mi caso lo voy a renombrar
mv /usr/share/ocsinventory-reports/ocsreports/install.php /usr/share/ocsinventory-reports/ocsreports/install.php.bk
Muy importante por seguridad restablecer la contraseña: engranaje de configuración> Mi cuenta> Contraseña.
Ya con todos estos pasos podemos estar satisfecho que realizamos la instalación de OCS Invetory, y podremos inventariar los dispositivos automáticamente, claro que debemos instalar el agente en cada dispositivo.
