  • IP or hostname (if the domain name has been set up/registered)
  • Ssh username
  • SSH password
  • SSH port
2. Connect to server using ssh. If you are on a Mac, use Terminal and type in the following command. If you are on a Window, you can use CMD (if CMD does not work, google “connecting to ssh on Window” to find the program
ssh -p xxxx yy@ zz.zz.zz.zz
: xxxx: port number yy: username zz.zz.zz.zz: ip or hostname
Select “Yes” if asked to continue connecting
3. To secure your ssh and your server, set up new user and deactivate root login via SSH by following steps 2, 3, and 5 in this tutorial:
Install sudo by:
yum –y install sudo
5. Following this link to set up LAMP stack:
In step 3, replace this part:
yum –y install firewalld
systemctl start firewalld
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --permanent --zone=public --add-port=7822/tcp
firewall-cmd –reload
systemctl enable firewalld
In step 4: choose PHP7.2
Follow this tutorial from steps 1-5, make sure instruction for specific steps as indicated above
6. Install the following packages to prepare for Open enventory
yum -y install php-mysql php-gd php-mbstring php-pear zlib-devel ghostscript ImageMagick libreoffice
systemctl restart httpd
7. Create a “download” folder; download OE (get the exact link from website: ); unzip OE and copy to the right location:
mkdir download
cd download
cp -rp open_enventory_2018-02-21/. /var/www/html/oe
With xx.xx.xx.xx: is the server’s ip address
9. The OE website should load like screenshot below
  • Database: choose the desired database’s name
  • Username: root
  • Password: use the mariadb password that was set up in step 5 of this tutorial
10. If successful, this page will load:
11. Modify .htaccess file
vi /var/www/html/oe/.htaccess
Modify the content of the file as in this screenshot. Important: these setting is for the server with configuration as indicated in the top of this tutorial
Save the file (hit Esc, type “:wq” and then Enter) and restart httpd service
systemctl restart httpd
12. Modify mysqld config:
vi /etc/my.cnf.d/server.cnf
Right after [mysqld], add:
max_allowed_packet = 64M # (or higher)
innodb_buffer_pool_size = 1024M # to about 50% of the available memory
Save the file (hit Esc, type “:wq” and then Enter) and restart httpd and mariadb services
systemctl restart httpd mariadb
You are done with the initial set up here. Open enventory is ready to be used at this time.
