What is WordOps ?

WordOps is a command line tool which eases server administration by providing the ability to setup an optimized LEMP stack (Nginx, PHP, MySQL) and to deploy WordPress sites with simple commands. It also come with a web dashboard where the main server metrics are displayed with links to all other tools shipped with WordOps.

WordOps not only installs and configures the packages needed to deploy a site (Nginx, PHP, MariaDB) but it also takes care of creating Nginx vhosts and the database, installing WordPress and even get a Let’s Encrypt SSL certificate, all in one command line.

It support multiple cache backend for WordPress, with or without additional plugin,  including Nginx fastcgi_cache and Redis cache (full-page cache with Nginx + object cache with Redis-cache plugin), WP-Super-Cache, Cache-Enabler and WP-Rocket.

It’s based on a highly optimized Nginx configurations and an hardened security with strict location directives.

Please read our contributor guide available in our documentation :


WordOps support PHP 7.2 (default), PHP 7.3 and PHP 7.4.

WordOps dashboard is available on https://YOUR.SERVER.IP:22222 or https://YOUR.SERVER.HOSTNAME:22222

By default, user is admin and password is also admin. After you logged in for the first time, you will have to change this password

During Nginx installation, WordOps secure his back-end with a self-signed SSL certificate. But WordOps will automatically replace this self-signed certificate with the first Let’s Encrypt SSL certificate issued on the server. So if you want to access WordOps back-end without receiving warning about the certificate, just create a site secured with a Let’s Encrypt SSL certificate, and use this domain to access to the back-end.

Additional information are available in the documentation.

Yes, since the release v3.9.5.4, our custom Nginx package is built with OpenSSL 1.1.1c and is available on all Linux distributions supported by WordOps : Ubuntu 16.04/18.04/19.04,  Debian 8/9/10 & Raspbian 9/10.

WordOps Let’s Encrypt stack is fully compatible with Cloudflare CDN, and you can use Cloudflare DNS API to issue your certificates even if the domain is not pointed to your server IP.

If you need/want to uninstall WordOps, you can use the following commands :

make a backup of your databases before purging stacks

1)  Purge WordOps stacks (nginx, mysql, php etc..)

wo stack purge --all

2) Uninstall WordOps

wget -qO wo && sudo bash wo --purge

You can find the MySQL root password in /etc/mysql/conf.d/my.cnf

Enable Brotli

mv /etc/nginx/conf.d/brotli.conf.disabled /etc/nginx/conf.d/brotli.conf

Disable Gzip

mv /etc/nginx/conf.d/gzip.conf /etc/nginx/conf.d/gzip.conf.disabled

Restart Nginx to apply changes

wo stack restart --nginx

Since the release v3.9.8, to make sure all WordOps users will always use the latest release available, WordOps do not force Nginx configuration update when running wo updateanymore. So you can safely upgrade to the latest WordOps release without impacting your sites. 

Then to update Nginx templates, you can use the command wo stack upgrade --nginx.
And it’s still possible to customize Nginx configurations, and to keep them after updating templates.

To disable configuration update on a file, you just have to create an empty file with the same name and the extension .custom

For example, if you want to customize the file /etc/nginx/conf.d/fastcgi.conf, you just have to create an empty file /etc/nginx/conf.d/fastcgi.conf.custom. This can be done with the command :

touch /etc/nginx/conf.d/fastcgi.conf.custom

If WordOps detect a .custom file, it will create another file with the .orig extension. This way, you will be able to update manually your custom configurations.

After upgrading WordOps to the latest release, you can apply new stack optimizations with wo stack upgrade

To upgrade Nginx and to apply new Nginx templates :

wo stack upgrade --nginx

To apply MariaDB configuration tuning :

wo stack upgrade --mysql

To apply latest PHP-FPM pool configuration

wo stack upgrade --php

You can increase file upload size by editing the variable upload_max_filesize in /etc/php/7.2/fpm/php.ini or /etc/php/7.3/fpm/php.ini depending on the PHP version in use.
You will also have to edit the directive client_max_body_size in /etc/nginx/nginx.conf.


There is no “best solution”, because there are benefits/disadvantage for each caching solution and it depend on your usage. Here some informations :

Cache backendcommand argumentdescription
fastcgi_cache--wpfcthe simplest solution, because it do not rely on any plugin excepted nginx_helper used to purge cache after content updates
redis-cache--wpredispowerful solution which support multi-server setup and it provide full-page cache in redis via Nginx + object-cache via Redis-Object-Cache plugin (optional)
wp-super-cache--wpscbasic solution based on a plugin which create and serve static html files.
wp-rocket--wprocketsolution based on a popular premium plugin with several additional features, compatible with Woocommerce and the most part of plugins
cache-enabler--wpcesolution based on an open-source plugin from keycdn

You can update WordPress admin password with the following command :

wo site update site.tld --password

Yes, since the release v3.9.8, WordOps support WP-Rocket with an optimized configuration to provide the best performances for your site. Because WP-Rocket is a paid plugin, we are not able to install it and to configure it during WordPress installation. So you will have to download it from the official site and to install it manually.


If there is no need to install an additional SSH client on Linux, on Windows we recommend MobaXterm because it include all features required to manage remote linux servers via SSH and there is a free version available
