Web presence step by step is a series of posts that show you to how to build a web presence.

In this chapter we install and configure Live Helper Chat to add text chat support to a website.

Installing the php-curl and php-bcmath extensions, enabling the Apache headers module, and restarting the Apache web server

Live Helper Chat requires the php-curl library, the php-bcmath library, and the headers Apache module.

Use an SSH terminal program to connect to the Ubuntu Linux cloud server you created in Chapter 3: Buying an Ubuntu Linux cloud server from Digital Ocean.

Enter these commands:

apt install php-curl php-bcmath
a2enmod headers
apachectl restart

Creating the MySQL database that will store data for the Live Helper Chat software

Enter this command:

mysql -u root -P

In the MySQL console, enter these commands (where ‘xxxxxx’ is your password):

create user lhc01@localhost;
set password for lhc01@localhost = 'xxxxxx';
create database lhc01;
use lhc01;
grant all privileges on * to lhc01@localhost;
quit

Viewing the extracted folders and files

We can see the lhc_web directory:

Using FileZilla to upload the lhc_web directory to the directory containing the documents for your website

We will use the FileZilla file transfer program to upload the directory “lhc_web” to the directory containing the documents for your website.

If you need detailed instructions on how to install and use FileZilla on Windows, MacOS, or Linux

This chapter assumes that you have read Chapter 7: Configuring the SSH server on an Ubuntu Linux cloud server to limit SFTP directory visibility within chroot jail directories, or that you are familiar with the FileZilla file transfer program.

Using Filezilla, connect to the Ubuntu Linux cloud server you created in Chapter 3: Buying an Ubuntu Linux cloud server from Digital Ocean. On the right (remote) side, select the directory that contains the documents for your website. On the left (local) side, select the directory that contains the “lhc_web” directory. Right-click or command-click on the directory, select Upload:
