\"install-lets-chat-on-an-ubuntu-vps\"In this blog post we will show you how to install Let’s Chat on an Ubuntu 14.04 VPS with the latest version of Nginx as a reverse proxy. Let’s Chat is a self-hosted chat for small teams which runs on Node.js and MongoDB. This guide should work on other Linux VPS<\/a> systems as well but was tested and written for Ubuntu 14.04 VPS<\/a>.<\/p>\n

<\/p>\n

Login to your VPS via SSH<\/h4>\n
ssh user@vps<\/pre>\n
Update the system and install necessary packages.<\/h4>\n
[user]$ sudo apt-get update && sudo apt-get -y upgrade\r\n[user]$ sudo apt-get install software-properties-common git build-essential<\/pre>\n
Install Node.js<\/h4>\n
We will install the latest nodejs package from Chris Lea’s repo.<\/p>\n
[user]$ sudo add-apt-repository ppa:chris-lea\/node.js\r\n[user]$ sudo apt-get update\r\n[user]$ sudo apt-get install nodejs<\/pre>\n
Install MongoDB<\/h4>\n
We will install the latest nodejs package from the official MongoDB repository.<\/p>\n
[user]$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10\r\n[user]$ echo 'deb http:\/\/downloads-distro.mongodb.org\/repo\/ubuntu-upstart dist 10gen' | sudo tee \/etc\/apt\/sources.list.d\/mongodb.list\r\n[user]$ sudo apt-get update\r\n[user]$ sudo apt-get install -y mongodb-org<\/pre>\n
Install Let’s Chat<\/h4>\n
Create a root directory for your Let’s Chat instance and clone the git repository from github using the following commands:<\/p>\n
[user]$ git clone https:\/\/github.com\/sdelements\/lets-chat.git ~\/lets_chat\r\n[user]$ cd ~\/lets_chat\r\n[user]$ npm install \r\n<\/pre>\n
When the installation is finished, run the following to start the Let’s Chat:<\/p>\n
[user]$ node start<\/pre>\n
If you see the below message, it means you’ve successfully installed Let’s Chat.<\/p>\n

Stop the process with Control-C<\/code> and continue with the Forever installation.<\/p>\n
In case you never heard of Forever, it is a tool which ensures that a given script runs forever.<\/p>\n
[user]$ sudo npm install forever -g<\/pre>\n
Now you can use forever to start your Let’s Chat instance.<\/p>\n
[user]$ cd ~\/lets_chat\r\n[user]$ forever start app.js<\/pre>\n
Install and Configure Nginx<\/h4>\n
The latest version of Nginx 1.8 is not available via the default Ubuntu repositories, so we will add the “nginx\/stable” PPA, update the system and install the nginx package.<\/p>\n
[user]$ sudo add-apt-repository ppa:nginx\/stable\r\n[user]$ sudo apt-get update\r\n[user]$ sudo apt-get install nginx<\/pre>\n
Create a new Nginx server block with the following content<\/p>\n
[user]$ sudo nano \/etc\/nginx\/sites-available\/lets_chat<\/pre>\n
server {\r\n    server_name lets_chat;\r\n    listen 80;\r\n\r\n    access_log \/var\/log\/nginx\/lets_chat-access.log;\r\n    error_log \/var\/log\/nginx\/lets_chat-error.log;\r\n\r\n    location \/ {\r\n        proxy_set_header   X-Real-IP $remote_addr;\r\n        proxy_set_header   Host      $host;\r\n        proxy_http_version 1.1;\r\n        proxy_set_header   Upgrade $http_upgrade;\r\n        proxy_set_header   Connection 'upgrade';\r\n        proxy_cache_bypass $http_upgrade;\r\n        proxy_pass         http:\/\/127.0.0.1:5000;\r\n    }\r\n \r\n}\r\n<\/pre>\n
Activate the server block by creating a symbolic link :<\/p>\n
[user]$ sudo ln -s \/etc\/nginx\/sites-available\/lets_chat \/etc\/nginx\/sites-enabled\/lets_chat<\/pre>\n
Test the Nginx configuration and restart the server<\/p>\n
[user]$ sudo nginx -t\r\n[user]$ sudo service nginx restart<\/pre>\n
That’s it. You can now open your browser and type the address of your Let’s Chat instance ex:  http:\/\/lets_chat<\/code>.<\/p>\n
For more information about how manage your Let’s Chat application ,please refer to the Let’s Chat<\/a> website.<\/p>\n
