ClassicPress

If you’re looking for performance and a lightweight, fully-featured CMS, then OpenLiteSpeed + ClassicPress is the ideal combination. ClassicPress is a fork of WordPress and its look and feel will be familiar to WordPress users everywhere. It does, however, have two key differences. Firstly, it retains the popular “classic” TinyMCE editor (no Gutenberg block editor). Secondly, it is built with performance in mind and is measurably faster than WP. The OpenLiteSpeed ClassicPress One-Click app is based on a standard ClassicPress image but includes several other great performance enhancements, including LiteSpeed’s popular LSCache optimization plugin.
This Classicpress + OpenLiteSpeed + LSCache image therefore offers performance that should more than meet most demands. OpenLiteSpeed ClassicPress One-Click automatically installs OpenLiteSpeed, LSCache, ClassicPress 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 ClassicPress 1-Click app" to create a Droplet with any plan you want. Click here to create an account and get a $100 Digital Ocean credit.

Step 2.

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

ssh root@use_your_server_ip

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

Note

If you try to visit the server's IP address before you SSH to the server, you’ll see a LiteSpeed landing page.

Step 3.

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

You can press CTRL+C and continue to SSH. The prompt will open again the next time you log in, and will continue to do so until you finish the whole setup.

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

Tip

Enter the root domain only, then the system will add both the root domain and the www domain for you..

You can also automatically apply Let's Encrypt SSL if your domain is pointed to this server already. Enter y and your email address to finish 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...

Do you wish to force HTTPS rewrite rule for this domain? [y/N]
Once finished, force HTTPS rules will be applied

Do you wish to update the system which include the web server? [Y/n]
This script will automatically go away after your domain has been added.

Step 4.

Visit the Server’s IP or Domain in your browser to finish the classicpress installation

!cpapp 1

!cpapp 2

Your system is installed and ready to use!

Tip

OpenLiteSpeed and LSCache are a powerful combination for your ClassicPress site, right out of the box. In addition, LSCache offers a variety of optimization features that can contribute to a superior PageSpeed score for your site. These features are disabled by default, but we encourage you to explore and experiment! Learn more about the LSCache plugin's settings.

How to Access the Installed Software

phpMyAdmin Access

!wpapp 3

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 classicpress 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.

!wpapp 6

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.

!listener 1

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

!wpapp 7

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

!wpapp 8

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 ClassicPress

If you already have a ClassicPress 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 ClassicPress 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 ClassicPress 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 ClassicPress

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

Install LSCache After Migration

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

!lscache 21

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

!wpapp 9

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

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 to upgrade to LSWS?

This script will:

  1. Generate an Apache config file from OpenLiteSpeed config

  2. Uninstall OpenLiteSpeed

  3. Install LiteSpeed and read the Apache config file

/bin/bash <( curl -sk https://raw.githubusercontent.com/litespeedtech/ls-cloud-image/master/Setup/ols2ent.sh ) -L
Note

Do not run this script on a production server or critical site without running it on a test site first. Get help by using the -H parameter for more information including how to revert back to OpenLiteSpeed if needed.

How do I 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 Certbot's Auto Renew Script Works?

Image comes with cert auto renew by default in /etc/cron.d/certbot. This cron job would get triggered twice every day to renew certificate. Line certbot -q renew will check if certificate is getting expired in next 30 days or not. If it is getting expired then it will auto renew it quietly without generating output and auto restart web server by hook. If certificate is not getting expired then it will not perform any action. While renewing certificate it will use same information provided during certificate creation such as email address, domain name, web server root path etc.

How do I fix Object Cache test fail issue?

Sometimes system upgrade may cause config file being updated. So first thing you can do is to check user permission For Memcached:

vi /etc/memcached.conf  
Make sure -u www-data

For Redis:

vi /lib/systemd/system/redis-server.service
Make sure Group=www-data

To verify, run the ulimit -n command. Output should read 65535.

NOTE: 65535 is an example. Feel free to use a different value

How do I Set Up Virtual-Host-Specific PHP?

By default virtual hosts inherit the version of PHP that is set at the server level. You may wish to use a different PHP version for certain virtual hosts. Follow the steps below to set up virtual-host-level PHP. Here we will use the PHP version 7.4 as an example.

Install PHP 7.4 and commonly used PHP extensions:

apt-get install lsphp74 lsphp74-common lsphp74-curl lsphp74-imagick lsphp74-imap lsphp74-json lsphp74-memcached lsphp74-mysql lsphp74-opcache lsphp74-redis -y

Navigate to WebAdmin console > Server Configuration > External App > Add > Type > LiteSpeed SAPI App to set up a server-level external application. Set the following values:

  • Name: lsphp74
  • Address: uds://tmp/lshttpd/lsphp74.sock
  • Max Connections: 35
  • Environment: LSAPI_AVOID_FORK=200M
  • Initial Request Timeout (secs): 60
  • Retry Timeout (secs): 0
  • Command: /usr/local/lsws/lsphp74/bin/lsphp
  • Instances: 1

Navigate to WebAdmin console > Virtual Hosts > your vhost > Script Handler > Add to add a virtual-host-level PHP handler. Set the following values:

  • Suffixes: php
  • Handler Type: LiteSpeed SAPI
  • Handler Name: [Server Level]:lsphp74

OpenLiteSpeed come with php detached mode by default, so need to restart php with command killall -9 lsphp to make settings take effect.

API Creation

DigitalOcean

In addition to creating a Droplet from the Openlitespeed ClassicPress 1-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":"litespeedtechnol-openlitespeedcla-18-04"}' \
    -H "Authorization: Bearer $TOKEN" \
    -H "Content-Type: application/json"
Not Support yet

Note

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