  1. Login into A2 account, service to find the following info:

  • 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 [email protected] zz.zz.zz.zz

: xxxx: port number yy: username zz.zz.zz.zz: ip or hostname

Select “Yes” if asked to continue connecting

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: https://sourceforge.net/projects/enventory/files/?source=navbar ); unzip OE and copy to the right location:

mkdir download
cd download
wget https://sourceforge.net/projects/enventory/files/open_enventory_2018-02-21.zip
unzip open_enventory_2018-02-21.zip
cp -rp open_enventory_2018-02-21/. /var/www/html/oe

8. Go to http://xx.xx.xx.xx/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.
