How to install WebERP on CentOS 8
webERP is a free, open source, complete web-based accounting and business management system. You only need a web browser and PDF reader to use webERP. Using webERP, you can manage many things, including purchase orders, online stores, manufacturing, sales, general ledger, and shipping. It is written in PHP and uses MariaDB as the database backend. This tutorial will show you how to install webERP on Apache and encrypt SSL on CentOS 8.
prerequisites
- Server running CentOS 8.
- A valid domain name pointing to the server IP.
- The root password is configured on the server.
Install LAMP server
First, install Apache, MariaDB, PHP and other PHP extensions using the following commands:
dnf install httpd mariadb-server php php-mysqli php-curl php-json php-cgi php-xmlrpc php-gd php-mbstring unzip -y
After installing all the packages, use the following commands to start the Apache and MariaDB services and enable them to start when the system reboots:
systemctl start httpd mariadbsystemctl enable httpd mariadb
Once completed, you can proceed to the next step.
Configure MariaDB
Next, you will need to set the MariaDB root password and ensure the security of the MariaDB installation. You can use the following commands to do so:
mysql_secure_installation
Answer all questions as follows:
Enter current password for root (enter for none):
Set root password? [Y/n] Y
New password:
Re-enter new password:
Remove anonymous users? [Y/n] Y
Disallow root login remotely? [Y/n] Y
Remove test database and access to it? [Y/n] Y
Reload privilege tables now? [Y/n] Y
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
Next, log in to the MariaDB shell using the following command:
mysql -u root -p
After connecting, use the following command to create a database and user for webERP:
MariaDB [(none)]> create database weberp;MariaDB [(none)]> create user [email protected] identified by 'password';
Next, use the following command to grant all privileges to the webERP database:
MariaDB [(none)]> grant all privileges on weberp.* to [email protected] identified by 'password';
Next, refresh the privileges and exit from MariaDB using the following command:
MariaDB [(none)]> flush privileges;MariaDB [(none)]> exit;
Once completed, you can proceed to the next step.
Install webERP
First, use the following command to download the latest version of webERP:
wget https://sourceforge.net/projects/web-erp/files/webERP_4.15.zip
After the download is complete, use the following command to extract the downloaded file to the Apache Web root directory:
unzip webERP_4.15.zip -d /var/www/html
Next, use the following commands to set the appropriate permissions and ownership:
chown -R apache:apache /var/www/html/webERPchmod -R 755 /var/www/html/webERP
Once completed, you can proceed to the next step.
Configure Apache for WebERP
Next, you will need to create a new Apache virtual host configuration file to host webERP. You can create it with the following command:
nano /etc/httpd/conf.d/weberp.conf
Add the following line:
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot /var/www/html/webERP
ServerName weberp.googlesyndication.com
<Directory /var/www/html/webERP/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/httpd/weberp.org-error_log
CustomLog /var/log/httpd/weberp.org-access_log common
</VirtualHost>
Save and close the file when you are done. Next, restart the Apache service to apply the changes:
systemctl restart httpd
Now, use the following command to verify the status of Apache:
systemctl status httpd
You should get the following output:
? httpd.service - The Apache HTTP Server

At this point, the Apache web server has been configured to host webERP. You can now proceed to the next step.
Let’s encrypt SSL to protect webERP
Next, you will need to install the Certbot client to install “Let’s Encrypt SSL” for WebERP. You can use the following command to install:
dnf install letsencrypt python3-certbot-apache
Next, use the following command to obtain and install an SSL certificate for your domain:
certbot --apache -d weberp.googlesyndication.com
