Installing WebSpellChecker v5.14+ on Linux with Apache HTTP Server

This step-by-step guide is intended to outline the main steps for the WebSpellChecker application installation on a Linux-based server with Apache HTTP Server. In this guide we will run you through the whole installation process from downloading installation packages to embedding spell/grammar checking functionality to your web-based system.

Before you begin:

Check if your environment configuration meets Installation requirements.
Acknowledge with Architecture diagram.
Make sure that you have a valid license:
First of all you need to get a valid License Ticket ID to proceed with the license activation. Depending on the server license type, it may be a commercial (e.g. 1 year) or a 30-day trial license. Except the validity period, there is no difference between ticket types from the technical perspective.
Good to know:
If you do not have a license yet, you can obtain it using one of the following ways:
request a 30-day trial license for evaluation and testing purposes;
acquire a commercial license by contacting our sales department.
Starting from v5.8.1 released on December 30, 2020, the license is no longer validated by or tied to the hardware characteristics of a machine or server. License for older versions of the packages is hardware-dependent.
If you are migrating WebSpellChecker from one server to another, you will need to deactivate (detach) a license on the current server and then reactivate it on a new one. Check carefully the Migrating License to New Server guide under the Licensing section.
If you have problems with your license, contact us.

1. Download installation package

Download WebSpellChecker Server installation package for the corresponding version of your operating system (OS). By default, it is provided on a license purchase or renewal. You can also request it by contacting us.

2. Install WebSpellChecker

2.1. Unpack the WebSpellChecker Server installation package (e.g. wsc_app_x64_5.x.x.x_xx.tar.gz).

tar  -xvzf wsc_app_x64_5.x.x.x_xx.tar.gz

2.2. Switch to the directory with the unpacked installation package using cd ./WSC_5.x.x.x/ and execute automated_install.pl script.

sudo perl automated_install.pl

If you are running the installation without root privileges, make sure all necessary directories have write permissions for the correct installation process.

2.3. Before proceeding with installation, read and confirm the terms and conditions of WebSpellChecker Software License Agreement.

Welcome to the WebSpellChecker (WSC) application installation wizard!

Before you go ahead with the installation, make sure that your environment configuration meets the WSC application system requirements.
If you are all set, please follow carefully the wizard instructions.

Prerequisite

Apache HTTP Server is already installed before installing WebSpellChecker. Thus, during the installation, the already existing Apache HTTP Server is auto-detected and becomes available for further configuration.

If you want to use Apache HTTP Server as a web server, perform the following steps:

Activate a new configuration.
Enable the required modules automatically.
Optionally install FastCGI module for Apache HTTP Server.
Restart Apache HTTP Server.

Step 1. Installation script tries to auto-detect the current version of Apache HTTP Server, its root directory, and path to its configuration file (httpd.conf). To accept the auto-detected Apache HTTP Server parameters, press Enter. Otherwise, specify the required version number, directory, and path to configuration file manually:

Auto-detecting the Apache HTTP Server parameters...
Press Enter to accept the auto-detected (if any) or enter your custom values.
Apache HTTP Server version is [2.4.18]: 
Apache HTTP Server root directory is /etc/apache2
Apache HTTP Server configuration directory is [/etc/apache2/conf-available]:

Step 2. Restart Apache HTTP Server to activate the configuration:

service apache2 reload

Step 3. Press Enter to enable additional and required mod_mime, mod_headers, mod_proxy and mod_proxy_http Apache HTTP Server modules. Otherwise, type n.

Modules:
headers
mime
proxy
proxy_http

Do you want to enable the required modules automatically? Enter 'y' or 'n' [y]:

Step 4. Install the FastCGI module for Apache HTTP Server if you have selected WSC Dialog Plugin for CKEditor (Option 4) or All products (Option 5) on step 2.5 before. Press Enter to install a generic mod_fastcgi module shipped with the installation package. It is recommended to use a certain external mod_fastcgi module which is specifically tailored for your system. However, you may decide to stick with a generic one shipped with the package.

Please note that it is recommended to use a certain external mod_fastcgi module which is specifically tailored for your system. However, you may decide to stick with a generic one shipped with the package.
Do you want to proceed with the mod_fastcgi installation from the WSC package? Enter 'y' or 'n' [y]:

Step 5. Press Enter to restart Apache HTTP Server for the changes to take effect.

Do you want to restart Apache HTTP Server? Enter 'y' or 'n' [y]:

2.13. Define the settings of the selected web server or Java application server.

Specify a domain name. The default value is locahost. Either enter your domain name or confirm the default value by pressing Enter.

Step 9: Specify Web Server or Application Server Settings.

Specify a domain name, the service virtual directory and a port number that will be used by a web server or application server.

Domain name [localhost]:

Specify the port number of a web server. The installer will suggest the port number based on the specified protocol and selected web server.

Web or application server port [443]:

Provide the name of the virtual directory for WebSpellChecker service. The default value is wscservice.

Service virtual directory [wscservice]:

On this step the installer summarizes the information that you have entered on the previous steps.

* PROTOCOL = https
* DOMAIN NAME = localhost
* INTERNAL APPLICATION SERVER = 2880
* WEB / JAVA APPLICATION SERVER PORT = 443
* VIRTUAL DIRECTORY = wscservice
* SERVICE URL = https://localhost:443/wscservice

3. Activate license

On this step you need to choose whether to run the license activation process. If you want to go ahead with the license activation, press Enter, then specify the License Ticket ID, and press Enter to activate the license automatically.

Step 9: Activate License.

Do you want to proceed with the license activation? Enter 'y' or 'n' [y]: 
Specify your License Ticket ID: Your_License_Ticket_ID

Do you want the installer to attempt to activate your license automatically? 
The automatic activation requires the Internet connection available on this machine.
Otherwise, please proceed with the manual activation instead. Enter 'y' or 'n'. [y]:

If you already have a license activated or you prefer to proceed with the license activation step later, you can skip this step.

Visit the License activation on Linux guide for more details on how to activate a license on a Linux server.

4. Finalize installation

If no errors happened during the setup, and everything is configured properly, you will receive a confirmation that the application has been installed.

Congratulations! The WSC application has been successfully installed to /opt/WSC directory.

5. Configure grammar engine

If the path to Java Virtual Machine (JVM) which is required for the Grammar engine is not auto-detected, the script will ask you to specify the correct path to JVM again.

Step 11: Specify Path to Java Virtual Machine.

At least Java 8 is required to use the Grammar engine. Please specify the path to Java Virtual Machine 
(JVM). You can skip this step and add the path to JVM manually in the '/opt/WSC/AppServer/AppServerX.xml' 
file (the PathToJavaVirtualMachine tag).

Do you want to specify a path to JVM? Enter 'y' or 'n' [y]:

You have an option to skip this step during the setup process and set a path to JVM manually. Refer to Enabling grammar engine guide to find out more.

6. Verify operability

Now you are ready to check if the installation process of the application went well, and all the components are functioning properly.

Step 12: Verify the WSC Application Operability.
