Install OCS Inventory-NG 2.0 on CentOS 6

This guide is based on a fresh install of CentOS 6.2 from the Minimal ISO. It assumes you have already performed basic system configuration steps such as setting up networking, time synchronisation, etc.

  1. Install the EPEL repo for some pre-requisites 
    rpm -ivH http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
  2. Edit '/etc/yum.repos.d/epel.repo' and inside the [epel] stanza, set enabled=0 Screenshot
  3. Update the base system 
    yum update -y
  4. Install pre-requisite packages 
    yum install -y make wget httpd mysql mysql-server php php-gd php-mysql php-mbstring mod_perl perl-XML-Simple perl-Net-IP perl-SOAP-Lite perl-DBI perl-DBD-MySQL
yum install -y --enablerepo=epel perl-Apache-DBI perl-Apache2-SOAP perl-XML-Entities
  5. Perform the initial MySQL setup 
    mysql_install_db
chkconfig --level 345 mysqld on
service mysqld start
mysql_secure_installation
    • Press Enter for current password
    • Type a password for the 'root' user
    • Re-enter your new 'root' password
    • Y to remove anonymous user
    • Y to disallow remote logon
    • Y to remove the test database
    • Y to reload the privilege tables
  6. Create the database for OCS. Replace <somepassword> with your own password (Hint: Don't use 'ocs') 
    mysql -u root -p
    CREATE DATABASE ocs;
GRANT ALL PRIVILEGES ON ocs.* to ocs@localhost IDENTIFIED BY '<somepassword>';
FLUSH PRIVILEGES;
QUIT
  7. Install OCS (Based on OCS 2.0.4) 
    cd ~
wget http://launchpad.net/ocsinventory-server/stable-2.0/2.0.4/+download/OCSNG_UNIX_SERVER-2.0.4.tar.gz
tar -xvzf OCSNG_UNIX_SERVER*.tar.gz
cd OCSNG_UNIX_SERVER*
sh ./setup.sh
    • Y to continue
    • Enter to accept 'localhost' as MySQL server
    • Enter to accept '3306' as MySQL port
    • Enter to accept '/usr/sbin/httpd' as Apache binary
    • Enter to accept '/etc/httpd/conf/httpd.conf' as Apache config file
    • Enter to accept 'apache' as Apache user
    • Enter to accept 'apache' as Apache group
    • Enter to accept '/etc/httpd/conf.d/' as Apache include directory
    • Enter to accept '/usr/bin/perl' as Perl interpreter
    • Y to install Communication server

    • Y to installation Administration server
    • Y to continue
    • Enter '/var/www' as location for Administration Server static files location
    • Enter '/var/www' as location for Download location
  8. Update database settings for OCS Server Screenshot
    • Edit '/etc/httpd/conf.d/z-ocsinventory-server.conf'
      • Change line 26 (OCS_DB_NAME) from 'ocsweb' to 'ocs'
      • Change line 27 (OCS_DB_LOCAL) from 'ocsweb' to 'ocs'
      • Change line 31 (OCS_DB_PWD) from 'ocs' to whatever you chose for your MySQL 'ocs' user password
  9. Update IPTables config to allow HTTP on port 80 Screenshot
    • Edit '/etc/sysconfig/iptables'
      • At line 11 (or just before the final 3 lines) insert 
        -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
    • Save the file and exit then run 
      service iptables restart
  10. Start Apache 
    chkconfig --level 345 httpd on
service httpd start
  11. Perform initial OCS config
    • Visit http://yourserver/ocsreports
    • You will be shown the database configuration page
      • Database: ocs
      • Username: ocs
      • Password: <somepassword>
      • Hostname: localhost
    • Click submit and wait a few seconds while the database is setup by the installation script
    • You will get a page which should show that everything was successful. You will be prompted to enter a string to show an agent the first time it contacts the OCS server. I leave it blank and click submit.
    • You will get a page informing you that installation is complete.
    • Delete the installation script 
      rm -f /var/www/ocsreports/install.php
    • Visit http://yourserver/ocsreports to login
      • Username: admin
      • Password: admin
    • You should change your 'admin' password after logging in.
    • OCS Server installation is complete. You can now begin deploying your agents.

Try "setenforce 0". Sounds like an SELinux issue which is disabled by that command. If that fixes it run:

sed -i 's/SELINUX=enforcing/SELINUX=permissive/' /etc/sysconfig/selinux

That will disable it permanently. Could also be that Apache is looking in the wrong spot for the OCS web data. From those steps you'll also want to enable the Apache and MariaDB services permanently with:

systemctl enable httpd
systemctl enable mariadb.service

Still pretty accurate.. I'm stuck with the problem that I get a 403 - forbidden on the http://yourserver/ocsreports.

For centos 7:

cd /tmp
wget https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm
yum install epel-release-7-2.noarch.rpm
yum install mariadb-server mariadb
systemctl start mariadb
mysql_secure_installation
systemctl enable mariadb.service

firewall-cmd --permanent --zone=public --add-port=3306/tcp
firewall-cmd --reload

mysql -u root -p
CREATE DATABASE ocs;
GRANT ALL PRIVILEGES ON ocs.* to ocs@localhost IDENTIFIED BY 'Your-Password';
FLUSH PRIVILEGES;
QUIT

yum install httpd php php-gd php-mysql php-mbstring mod_perl perl-XML-Simple perl-Net-IP perl-SOAP-Lite perl-DBI perl-DBD-MySQL

cd ~
wget https://launchpad.net/ocsinventory-server/stable-2.1/2.1.2/+download/OCSNG_UNIX_SERVER-2.1.2.tar.gz
tar -xvzf OCSNG_UNIX_SERVER-2.1.2.tar.gz
cd OCSNG_UNIX_SERVER-2.1.2
sh ./setup.sh

firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --reload
systemctl start httpd

Go to website: http://yourserver/ocsreports

When I get a chance I'll have a look into that error. OCS is now up to 2.1.2 and CentOS is up to 7.0 so I'm expecting some changes are required to the instructions since this guide was written over 2yrs ago.

Hi,

I change permission of dbconfig.inc.php and disabled selinux too and not work, the message keeps coming:

ERROR: can't write in directory (on dbconfig.inc.php), please set the required rights in order to install ocsinventory (you should remove the write mode after the installation is successfull)

See my previous comment about setting the correct permissions on the dbconfig.inc.php file so that the setup script can modify it.

Once you have completed setup, you also need to change the permissions back so that the file can not be modified again.

It sounds like the user your web server runs under is not the same as the owner of your website files.

Based on my example, you would run "chmod 0777 /var/www/ocsreports/dbconfig.inc.php" then go through the setup.

Once you have completed the setup, you should run "chmod 0755 /var/www/ocsreports/dbconfig.inc.php".
