Command Line Apache MySQL PHP

Welcome to Clamp

Clamp is a Command Line Apache MySQL PHP for Mac OS X made for local development. It aims at being ultra simple to use and configure.

• Automatically creates a host and a database.
• Uses system's Apache and PHP, and MariaDB using homebrew.
• System-wide configuration remains unchanged.
• All data are self contained in a .clamp folder.
• Configuration is done using a clamp.json JSON file.

It should only be used for local development. It is absolutely not secure for anything else.

Installation

$ brew tap jide/clamp
$ brew install clamp

You must have homebrew installed.

OS X Yosemite

Since in Yosemite Apache version is 2.4, you may have to correct your .htaccess file :

  Order allow,deny

Becomes :

  <IfModule mod_authz_core.c>
    Require all denied
  </IfModule>
  <IfModule !mod_authz_core.c>
    Order allow,deny
  </IfModule>

Usage

To serve the current folder :

$ clamp

Use Ctrl + C to exit.

By default, this will start apache, create a database named "db", start MySQL daemon and set the host as "localhost". You can customize these settings using the configuration file.

You can connect to MySQL through localhost:3306 with user "root" and a blank password. Sequel pro is a great app for managing your databases.

All commands

$ clamp apache start // Start apache.
$ clamp apache stop // Stop apache.

$ clamp mysql start // Install database, start daemon and create db.
$ clamp mysql stop // Shortcut for mysql daemon stop.
$ clamp mysql daemon start // Start mysql daemon.
$ clamp mysql daemon stop // Stop mysql daemon.
$ clamp mysql install // Install.
$ clamp mysql create-db [database] // Create a database.
$ clamp mysql export [database?] [file?] // Export database.
$ clamp mysql import [file?] [database?] // Import SQL file.

$ clamp host set [host] // Add a host.
$ clamp host unset [host] // Remove a host.

$ clamp config write // Writes the default clamp.json file in the current folder.

Configuration

All configuration resides in a clamp.json file. All the parameters are built using this file and then passed to the different commands. It uses a few tricks that make it very flexible.

To copy the default configuration file in the current directory, use clamp config write.

A simple configuration :

{
    "address": "localhost",
    "memory": "256M",
    "database": "db",
}

You can also configure each command and their options :

{
    "apache": {
        "commands": {},
        "options": {}
    },
    "host": {
        "options": {}
    },
    "mysql": {
        "commands": {},
        "databases": [],
        "options": {}
    },
    "php": {
        "options": {}
    }
}

See the default configuration file for a detailed view of the options.

You can insert the current working direcory :

"errorlog": "'{{$cwd}}/.clamp/logs/apache.error.log'"

You can even use a path to another option :

{
    "php": {
        "options": {
            "memory_limit": "{{$.memory}}",
            "pdo_mysql.default_socket": "{{$.mysql.options.socket}}",
            "mysql.default_socket": "{{$.mysql.options.socket}}",
            "mysqli.default_socket": "{{$.mysql.options.socket}}"
        }
    }
}

File structure

Everything is self-contained in a .clamp folder inside your project: The database files, the logs and the socket / PID files.

.clamp
  - data // The database files
  - logs // Apache and MySQL logs
  - tmp // PID files and sockets

Note that this is the default configuration. But since you can define these paths in the configuration file, you are free to use a completly different structure.
