Command Shortcuts - Centmin Mod LEMP Stack

How to Run the Centmin Mod Menu (centmin.sh)

The centmin command is the recommended way to launch the Centmin Mod interactive menu. It is a shell alias installed at /usr/bin/centmin and can be run from any directory:

# Recommended: use the centmin alias (available system-wide)
centmin

# Alternative: run centmin.sh directly from its full path
cd /usr/local/src/centminmod && ./centmin.sh

For non-interactive vhost creation without entering the menu, use the nv command at /usr/bin/nv:

# Create vhost with Let's Encrypt SSL (recommended)
nv -d yourdomain.com -s lelived

# Create vhost with self-signed SSL (testing only)
nv -d yourdomain.com -s y

Centmin Mod installs command shortcuts that let you type a single word to edit configuration files or manage services via SSH. These shortcuts are installed during the initial Centmin Mod installation and are available system-wide.

The config editing shortcuts use the nano text editor. Services must be installed for their respective shortcuts to work (e.g., memcached shortcuts require memcached to be installed).

Configuration Editing

Config File Shortcuts

Edit server configuration files with a single command. Each shortcut opens the file in the nano text editor.

Command	Description	File Path
`phpedit`	Edit php.ini	`/usr/local/lib/php.ini`
`mycnf`	Edit MariaDB/MySQL my.cnf	`/etc/my.cnf`
`fpmconf`	Edit php-fpm.conf	`/usr/local/etc/php-fpm.conf`
`nginxconf`	Edit nginx.conf	`/usr/local/nginx/conf/nginx.conf`
`vhostconf`	Edit Nginx default virtual.conf	`/usr/local/nginx/conf/conf.d/virtual.conf`
`phpinc`	Edit Nginx php.conf include	`/usr/local/nginx/conf/php.conf`
`dropinc`	Edit Nginx drop.conf include	`/usr/local/nginx/conf/drop.conf`
`statfilesinc`	Edit Nginx staticfiles.conf include	`/usr/local/nginx/conf/staticfiles.conf`

The vhostconf shortcut only edits the default virtual.conf file, not additional vhost domain.com.conf files added later via menu option 2.

Service Management

Restart Nginx and PHP-FPM

Use these commands to restart Nginx and PHP-FPM in Centmin Mod. Always test the configuration with nginx -t before restarting Nginx to catch syntax errors. The nprestart shortcut restarts both together.

# Always test Nginx config before restarting
nginx -t

# Restart Nginx and PHP-FPM together
nginx -t && nprestart

# Restart Nginx only
nginx -t && ngxrestart
# or: nginx -t && systemctl restart nginx

# Restart PHP-FPM only
fpmrestart
# or: systemctl restart php-fpm

MariaDB version
Server specs (CPU, RAM, disk usage)
Kernel info and OS version

cminfo

For more details, see the forum discussion.

PHP Version Update Notifications

Centmin Mod can display PHP and Nginx version update alerts on every SSH login, helping you keep track of available updates without manually checking. The notification appears as part of the SSH login MOTD (Message of the Day).

To enable PHP and Nginx update notifications on SSH login, set DMOTD_PHPCHECK='y' in your persistent config file:

# /etc/centminmod/custom_config.inc
DMOTD_PHPCHECK='y'

The /etc/centminmod/custom_config.inc file persists across Centmin Mod updates. Settings placed here are not overwritten when you update Centmin Mod.

For more details, see the forum discussion.

Custom Aliases

Centmin Mod shortcuts are stored as files in /usr/bin/. For additional custom shortcuts, you can create bash aliases in /root/.bashrc.

Create a shortcut to change to the Centmin Mod directory:

alias cmod='pushd /usr/local/src/centminmod/'

Make the alias persistent by adding it to /root/.bashrc:

echo "alias cmod='pushd /usr/local/src/centminmod/'" >> /root/.bashrc

List all active aliases:

alias

Using pushd instead of cd lets you use popd to return to your previous directory. Always backup /root/.bashrc before editing.
