Centmin Mod Menu Options

The centmin.sh shell menu (also available via the centmin alias at /usr/bin/centmin) is the heart of Centmin Mod. Main Menu Option 2 adds a new Nginx vhost domain; Option 5 upgrades or downgrades PHP; Option 6 manages MySQL databases; Option 11 manages MariaDB upgrades.

Launch the menu by running centmin or cd /usr/local/src/centminmod && ./centmin.sh via SSH.

Auto-Installed Components

CSF Firewall (ConfigServer Security & Firewall) is automatically installed during the initial Centmin Mod installation. It is not a menu option — CSF is managed directly via csf command-line tools (e.g., csf -r to restart, csf -a IP to allow an IP). See the CSF Firewall documentation for full details.

Installation & Updates

Menu Option 1 — Centmin Install

Initial installation of the full Centmin Mod LEMP stack including Nginx, MariaDB, and PHP-FPM.

Update Centmin Mod Code Base

Update the Centmin Mod code base to the latest version via the built-in updater submenu.

Nginx & vHost Management

Add Nginx Vhost Domain

Centmin Mod Main Menu Option 2 creates a new Nginx virtual host (vhost) — a new website domain on the server. Auto-generates the Nginx vhost configuration file, domain directories, and a Pure-FTPd virtual FTP user. For production sites, use Let’s Encrypt SSL (-s lelived recommended). Also available via the nv command shortcut.

Nginx Upgrade / Downgrade

Upgrade or downgrade the Nginx web server version with recompilation of all enabled modules.

Add Wordpress Nginx vhost + Cache Plugin

Create a WordPress-optimized Nginx vhost with auto-installed caching plugin for improved performance.

centmin.sh Main Menu: Option 2 — Add Nginx Virtual Host (vhost)

Centmin Mod’s Main Menu Option 2 creates a new Nginx virtual host (vhost) — a new website domain on the server. It is also available via the nv command shortcut. Main Menu Option 2 auto-generates the Nginx vhost configuration file, sets up the document root directories, configures SSL, and creates a Pure-FTPd virtual FTP user (Centmin Mod uses the Pure-FTPd FTP server). For production sites, use the Let’s Encrypt SSL option -s lelived (recommended). For development or testing, you can use a self-signed SSL certificate with -s y.

# Recommended: Let's Encrypt production SSL
nv -d yourdomain.com -s lelived -u ftpusername

# Development/testing only: self-signed SSL certificate
nv -d yourdomain.com -s y -u ftpusername

centmin.sh Main Menu: Option 4 — Nginx Upgrade / Downgrade

Menu Option 4 is used to upgrade or downgrade the Nginx web server version on a Centmin Mod server. Running Option 4 recompiles Nginx from source with all enabled modules. Use Option 4 to upgrade Nginx to a newer release, or downgrade to a previous version if a compatibility issue arises after an upgrade.

The Nginx upgrade and downgrade process preserves existing vhost configurations, SSL certificates, and custom Nginx modules. After the upgrade or downgrade completes, Nginx is automatically restarted. To update Nginx, run centmin and select option 4. The upgrade/downgrade typically takes 5–20 minutes depending on server CPU speed.
