Following are the steps to install Visionhelpdesk’s Livechat on Linux server:

1. Install nodejs [version 12.x]

2. Install npm [vesion 6.x]

3. Install pm2 [version 3.5.x]
   

   curl -sL https://rpm.nodesource.com/setup_12.x | bash -
   yum -y install nodejs
   yum install gcc-c++ make
   npm install pm2@latest -g

4. Copy server.js, router.js and package.json on root or /

5. Go to the path where package.json is copied

6. Execute the command
   

   npm install

7. If you have cPanel hosting along with a lightspeed webserver, you will need to add rewrite rules under the path as given below:
   

   #cd /etc/apache2/conf.d/userdata
   #vi chat.conf
   
   Add the below code into the chat.config file:
   
   <IfModule litespeed>
   RewriteRule /support/chat/(.*) http://127.0.0.1:3000/$1 [P]
   #<Location /support/chat >
   #ProxyPass http://127.0.0.1:3000
   #ProxyPassReverse http://127.0.0.1:3000
   #</Location>
   </IfModule>

8. Set the SSL
9. Start the server using the below command

#pm2 start server.js

Note: If port 3000 is already in use then need to create .env file at the same location where server.js is stored and put the port as below in that file:

PORT=3001
virtualDirPath=''

Also, make the changes in reverse proxy accordingly.

10. Save the changes and restart the Lightspeed service
