Quick Start

How to Access the Installed Software


Connect to phpMyAdmin at the following URL:

Get the MySQL root password:

sudo sed -n 1p .db_password

Get the MySQL WordPress user password:

sudo sed -n 2p .db_password

Web Server Control Panel Access

Navigate with your favorite browser to your server’s IP address or domain name and append port(

WebAdmin Admin Password

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

ufw allow from to any port 7080
You can also allow all IPs access to port 7080:
ufw allow 7080
We suggest turning this port off once you've finished setup:
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., to the server’s IP address
  • An A record from the domain prefaced with www (e.g., to the server’s IP address.

Step 2. Add Domain to Listener

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

Add Domain to Listener

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 -d

If certificate verification is a success, you should find your certificate files stored in /etc/letsencrypt/

Step 4. Set SSL for HTTPS


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

  • Private Key File = /etc/letsencrypt/live/
  • Certificate File = /etc/letsencrypt/live/
  • 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

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 Web Server WebAdmin > Virtual Hosts > Rewrite > Rewrite Rules

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$$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 such as WinSCP FTP client, recommended. Read our Quick Start Guide on WinSCP to upload files to any web server. WordPress also has File Manager Plugin that makes file upload a breeze.

Methods for Migrating WordPress

If you already have a WordPress site elsewhere, you can migrate it using one of the following methods.

Single-Site by Duplicator Plugin

  1. Install and activate the Duplicator plugin on the WordPress site you’re copying from.
  2. Navigate to Duplicator > Packages, then click the Create New button.
  3. Go through the wizard. When you see “Package Completed,” click the One-Click Download link to download two files.
  4. Move the two files (installer.php and a zip file) into the folder you’ll want the WordPress site in.
  5. Visit installer.php in a web browser and you should see a wizard screen.
  6. Click I have read and accept all terms & notices and Next
  7. You’ll need to have a database ready. Enter the database name, user, and password.
  8. Click the Site Login button and log in to your WordPress site using the same username and password as you have on the remote site.

Multi-Site by Duplicator Plugin

  1. Install plugin.
  2. Network activate plugin.
  3. On site 1, perform the backup. That will capture the entire site into a package.
  4. Restore the site in the new location just as in the Single Site procedure.

Install LSCache After Migration

This step is only necessary if you have migrated a WordPress installation or it’s a fresh WordPress installation.

Install LSCache After Migration

To benefit from high performance and a nice page score, don’t forget to install the LSCache Plugin

Improve Your Page Score

Switch Object Cache Method

Switch Object Cache Method

By default we have Memcached enabled. To swich to Redis is easy. Just copy the Redis socket path to LSCache Plugin > Settings > Advanced > Object Cache and save:

  • Memcached: /var/www/memcached.sock
  • Redis: /var/run/redis/redis-server.sock


OpenLiteSpeed is an amazing application that is free and open source. It can seriously improve the performance of your WordPress site.
