Node.js¶

The OpenLiteSpeed Node.js One-Click app automatically installs performance web server OpenLiteSpeed, and Node.js. This image tends to be more than 4 times faster than Node.js with Nginx! OpenLiteSpeed features easy setup for SSL and RewriteRules. OLS is flexible and also supports Python and Ruby apps, as well as CMSs like WordPress.

Quick Start¶

Step 1.¶

Use the "OpenLiteSpeed Node.js Marketplace Image" to create a ECS with any plan you want.

Step 2.¶

An interactive script that runs will prompt you for your domain or subdomain:

Please input a valid domain:
Please verify it is correct. [y/N]

Enter your root domain only. The system will automatically add the www subdomain as well.

If your domain is already pointed to this server, you will have the option of automatically applying Let's Encrypt SSL. Enter y and your email address to complete the process:

Do you wish to issue a Let's encrypt certificate for this domain? [y/N]
Please enter your E-mail:
Please verify it is correct: [y/N]

Once finished, you should see Certificate has been successfully installed...

You can force HTTPS rules to be applied:

Do you wish to force HTTPS rewrite rule for this domain? [y/N]

Complete the process by pressing Y:

Do you wish to update the system which include the web server? [Y/n]

You should not be prompted to initiate this setup again.

Step 3.¶

Visit the default script by entering http://Server_IP on your browser and you should see Hello World from OpenLiteSpeed Node.js.

Start editing the Node.js file here

vim /usr/local/lsws/Example/html/node/app.js

Optional but recommended:¶

Update system software.

sudo apt-get update && sudo apt-get upgrade -y

Your system is installed and ready to use!

Components¶

The OpenLiteSpeed Node.js 1-Click Droplet installs several packages and performs other actions on your system.

Package Installation¶

Other Actions¶

• Enables the UFW firewall to allow only SSH (port 22), HTTP (port 80) and HTTPS (port 443) access.

Benchmark Comparison¶

Use the following command to test from a 4-CPU plan server(ab) to a 4-CPU plan server(DOMAIN)

ab -n 100000 -k -H "Accept-Encoding: gzip,deflate" -c 100 http://DOMAIN/

Requests per Second (The larger the number, the better)

How to Access the Installed Software¶

From a terminal on your local computer, connect to the server as root, like so:

ssh root@192.0.2.0

Be sure to substitute the server’s public IP address for 192.0.2.0.

Web Server Control Panel Access¶

Get the WebAdmin admin password:

cat .litespeed_password

Visit https://use_your_droplet_ip:7080 to access WebAdmin in a browser.

By default, WebAdmin uses port 7080. To allow access to 7080 from your IP(e.g. 192.0.2.0):

ufw allow from 192.0.2.0 to any port 7080

ufw allow 7080

ufw delete allow 7080

Optional Setup¶

Enable HTTPS¶

Setting up an SSL certificate enables HTTPS on the web server, which secures the traffic between the server and the clients connecting to it. Certbot is a free and automated way to set up SSL certificates on a server.

Step 1. Register Domain¶

To use Certbot, you’ll need a registered domain name and DNS records:

• An A record from the domain (e.g., example.com) to the server’s IP address

• An A record from the domain prefaced with www (e.g., www.example.com) to the server’s IP address.

Step 2. Add Domain to Listener¶

Navigate to OpenLiteSpeed WebAdmin Console > Listeners, and add Your Domain to HTTP/HTTPS.

Step 3. Certbot¶

Once the DNS records are set up, you can generate the SSL certificate. Be sure to substitute the correct domain name in the following command:

certbot certonly --webroot -w /var/www/html/ -d example.com -d www.example.com

Step 4. Set SSL for HTTPS¶

Navigate to OpenLiteSpeed WebAdmin Console > Listeners > SSL, and edit the following three items:

• Private Key File = /etc/letsencrypt/live/example.com/privkey.pem
• Certificate File = /etc/letsencrypt/live/example.com/fullchain.pem
• Chained Certificate = Yes

Save and perform a Graceful Restart.

Now your server should support TLS1.1, TLS 1.2, and TLS 1.3.

Step 5. Redirect HTTP to HTTPS¶

HTTPS traffic on port 443 is already allowed through the firewall. After you set up HTTPS, you can optionally rewrite all HTTP traffic to HTTPS.

Add the following rules to OpenLiteSpeed WebAdmin Console > Virtual Hosts > Rewrite > Rewrite Rules

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://example.com/$1 [R,L]

Method for Uploading Files¶

You can serve files from the web server by adding them to the web root using SFTP or other tools.

Frequently Asked Questions¶

How do I Reset my Web Server WebAdmin Password?¶

If you forget your password, you may run the following command to reset it:

/usr/local/lsws/admin/misc/admpass.sh

It will ask for the WebAdmin username, which should be admin. Then, enter your new password.

How do I Create Additional Virtual Hosts?¶

• Auto Setup via Script This method will automatically set up Listener/VirtualHost/Force SSL/Let's Encrypt/WordPress.

  Interactive mode

  wget https://raw.githubusercontent.com/litespeedtech/ls-cloud-image/master/Setup/vhsetup.sh
  chmod +x vhsetup.sh
  bash vhsetup.sh

  Or just run the script without downloading it:

  /bin/bash <( curl -sk https://raw.githubusercontent.com/litespeedtech/ls-cloud-image/master/Setup/vhsetup.sh )

  CLI mode

  wget https://raw.githubusercontent.com/litespeedtech/ls-cloud-image/master/Setup/vhsetup.sh
  chmod +x vhsetup.sh
  bash vhsetup.sh -d www.example.com -le admin@example.com -f -w

  Or just run the script without downloading it:

  /bin/bash <( curl -sk https://raw.githubusercontent.com/litespeedtech/ls-cloud-image/master/Setup/vhsetup.sh ) -d www.example.com -le admin@example.com -f -w

  • Please be sure that your domain is already pointing to the server when using -le YOUR_EMAIL

  • Please be sure that your environment has php/sql service/sql root password when using -w

• Manual Setup By default, OpenLiteSpeed has an example virtual host already created. You can create more virtual hosts if you like. See Create Virtual Hosts on OpenLiteSpeed.

How do I Create Additional Apps by Context?¶

How do I Change the Node.js Startup File?¶

If you want to change the default startup file name from app.js to node.js, just update the Context and set Startup File = node.js.

How do I upgrade Node.js to latest stable version¶

Install Node.js by using n module

sudo n stable

     install : node-vX.X.X
       mkdir : /usr/local/n/versions/node/X.X.X
       fetch : https://nodejs.org/dist/vX.X.X/node-vX.X.X-linux-x64.tar.gz
################################################################################## 100.0%
   installed : vX.X.X

ln -sf /usr/local/n/versions/node/X.X.X/bin/node /usr/bin/node

How do I use an Express app on this image?¶

Setting up an Express app is easy. First, install the Express.js module:

npm install express --save

Then, change your startup file (app.js) from a Node.js program to an Express JS program:

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => res.send('Hello World from OpenLitespeed Express JS!'))

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

Finally, restart OpenLiteSpeed:

service lsws restart

And you're done!
