WordPress

The OpenLiteSpeed WordPress One-Click app is based on a standard WordPress image, but includes several great performance enhancements, including LiteSpeed's popular LSCache optimization plugin. This Wordpress + OpenLiteSpeed + LSCache image tends to be more than 300 times faster than a regular WordPress image!

OpenLiteSpeed WordPress One-Click automatically installs OpenLiteSpeed, LSCache, WordPress and any dependences. It also automates initial setup for components like Object Cache and PHP OPCache to reduce the time it takes to optimize a web server.

Quick Start

Step 1.

DigitalOcean

Use the "OpenLiteSpeed WordPress One-Click app" to create a Droplet with any plan you want

How to Access the Installed Software

phpMyAdmin Access

Connect to phpMyAdmin at the following URL:

https://example.com/phpmyadmin

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

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. 1.2.3.4):

ufw allow from 1.2.3.4 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., 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 Web Server WebAdmin > Listeners, and add Your Domain to HTTP/HTTPS. Screenshot

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

Step 4. Set SSL for HTTPS

Screenshot

Navigate to OpenLiteSpeed Web Server WebAdmin > 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

Screenshot

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 ^(.*)$ 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.

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.

Manually by WordPress

  1. Back up WordPress
  2. Back up the database
  3. Move the directories

Install LSCache After Migration

This step is only necessary if you have migrated a previous WordPress installation. Otherwise, the image installs LSCache for you.

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

Screenshot

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

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?

By default we have an example virtual host already. You can create more virtual hosts if you like. See Create Virtual Hosts on OpenLiteSpeed.

How to verify if cache is working?

Visit your website using Chrome. Navigate to Chrome menu > More tools > Developer tools > Network, or simply use the shortcut Ctrl+Shift+I to bring it up. The test page may contain many requests, but you can just click your main domain to check the header. You might see X-LiteSpeed-Cache: miss or X-LiteSpeed-Cache: hit. Normally the first visit to a page is a miss, but subsequent visits should be a hit.

How do I Create Additional Databases?

Method 1: Through phpMyAdmin
Method2 : Through SSH

Log into MySQL as root:

mysql -u root -p
Add a new database wordpress2 and user newuser with password password:
create database wordpress2;
grant all privileges on wordpress2.* to 'newuser'@'localhost' identified by "password";
Flush priveleges;
exit

How do I Change PHP Parameters?

Edit the following file to configure PHP parameters:

vi /usr/local/lsws/lsphp72/etc/php/7.2/litespeed/php.ini

NOTE: We are using LSPHP 7.2 as example. If you are using a different version, please adjust the number in the URL accordingly. To increase the allowed file size, for example, you would make the following edits:

upload_max_filesize = 64M
post_max_size = 64M

Other parameters in the file may also be changed, if needed.

API Creation

DigitalOcean

In addition to creating a Droplet from the Openlitespeed WP One-Click application using the control panel, you can also use the DigitalOcean API.

The following example creates an Openlitespeed WP 18.04 Droplet called “My-Droplet” in the NYC3 datacenter, with 1 GB RAM:

curl -X POST "https://api.digitalocean.com/v2/droplets" \
    -d'{"name":"My-Droplet","region":"nyc3","size":"s-1vcpu-1gb","image":"openlitespeed-wp-18-04"}' \
    -H "Authorization: Bearer $TOKEN" \
    -H "Content-Type: application/json"

Note

This request, like any other request that makes a change to your account, requires that your token has “write” scope assigned to it.
