LEMP
The LEMP stack is a common infrastructure designed to run PHP applications, it is similar to the more well known LAMP stack but replaces Apache with nginx as the web server.
Lando offers a configurable recipe for developing LEMP apps.
Note that this recipe is for a generic LEMP stack. Definitely check out Lando's other recipes before you use this as there may be one designed specifically for use with your framework.
Getting Started
Before you get started with this recipe we assume that you have:
- Installed Lando and gotten familiar with its basics.
- Initialized a Landofile for your codebase for use with this recipe.
- Read about the various services, tooling, events and routing Lando offers.
However, because you are a developer and developers never ever RTFM, an example of using the LEMP recipe to run the older CakePHP 2.0 project is shown below:
Note that CakePHP could be any other php framework or your own custom php thing.
# Initialize a LEMP recipe using the latest CakePHP 2.0 version
lando init \
--source remote \
--remote-url git://github.com/cakephp/cakephp.git \
--remote-options="--branch 2.x --depth 1" \
--recipe lemp \
--webroot . \
--name my-first-lemp-app
# Start it up
lando start
# List information about this app.
lando info
Configuration
While Lando recipes set sane defaults so they work out of the box, they are also configurable.
Here are the configuration options, set to the default values, for this recipe's Landofile. If you are unsure about where this goes or what this means we highly recommend scanning the recipes documentation to get a good handle on how the magicks work.
recipe: lemp
config:
php: '7.3'
composer_version: '2.0.7'
webroot: .
database: mysql:5.7
xdebug: false
config:
server: SEE BELOW
php: SEE BELOW
database: SEE BELOW
vhosts: SEE BELOW
Note that if the above config options are not enough, all Lando recipes can be further extended and overriden.
Choosing a php version
You can set php
to any version that is available in our php service. However, you should make sure that whatever framework or custom code you write is designed to work with your choice.
The recipe config to set the LEMP recipe to use php
version 5.4
is shown below:
recipe: lemp
config:
php: '5.4'
Choosing a composer version
You can set composer_version
to any version that is available in our php service.
recipe: backdrop
config:
composer_version: '1.10.1'
Choosing a database backend
By default, this recipe will use the default version of our mysql service as the database backend but you can also switch this to use mariadb
or 'postgres' instead. Note that you can also specify a version as long as it is a version available for use with lando for either mysql
, mariadb
or postgres
.
If you are unsure about how to configure the database
, we highly recommend you check out the mysql, mariadband 'postgres' services before you change the default.
Using MySQL (default)
recipe: lemp
config:
database: mysql
Using MariaDB
recipe: lemp
config:
database: mariadb
Using Postgres
recipe: lemp
config:
database: postgres
Using a custom version
recipe: lemp
config:
database: postgres:9.6
Using xdebug
This is just a passthrough option to the xdebug setting that exists on all our php services. The tl;dr
is xdebug: true
enables and configures the php xdebug extension and xdebug: false
disables it.
recipe: lemp
config:
xdebug: true|false
However, for more information we recommend you consult the php service documentation.
Using custom config files
You may need to override our default LEMP config with your own.
If you do this, you must use files that exist inside your application and express them relative to your project root as shown below:
Note that the default files may change based on how you set both ssl
and via
. Also note that the vhosts
and server
config will be explicitly for nginx
. We highly recommend you check out the nginx if you plan to use a custom vhosts
or server
config.
A hypothetical project
Note that you can put your configuration files anywhere inside your application directory. We use a config
directory but you can call it whatever you want such as .lando
in the example below:
./
|-- config
|-- default.conf
|-- my-custom.cnf
|-- nginx.conf
|-- php.ini
|-- index.php
|-- .lando.yml
Landofile using custom LEMP config
recipe: lemp
config:
config:
php: config/php.ini
database: config/my-custom.cnf
Connecting to your database
Lando will automatically set up a database with a user and password and also set an environment variable called LANDO INFO
that contains useful information about how your application can access other Lando services.
The default database connection information for a LEMP site is shown below:
Note that the host
is not localhost
but database
.
database: lemp
username: lemp
password: lemp
host: database
# for mysql
port: 3306
# for postgres
# port: 5432
You can get also get the above information, and more, by using the lando info
command.
Importing Your Database
Once you've started up your LEMP site, you will need to pull in your database and files before you can really start to dev all the dev. Pulling your files is as easy as downloading an archive and extracting it to the correct location. Importing a database can be done using our helpful lando db-import
command.
# Grab your database dump
curl -fsSL -o database.sql.gz "https://url.to.my.db/database.sql.gz"
# Import the database
# NOTE: db-import can handle uncompressed, gzipped or zipped files
# Due to restrictions in how Docker handles file sharing your database
# dump MUST exist somewhere inside of your app directory.
lando db-import database.sql.gz
You can learn more about the db-import
command over here
Tooling
By default, each Lando LEMP recipe will also ship with helpful dev utilities.
This means you can use things like drush
, composer
and php
via Lando and avoid mucking up your actual computer trying to manage php
versions and tooling.
lando composer Runs composer commands
lando db-export [file] Exports database from a service into a file
lando db-import <file> Imports a dump file into database service
lando mysql|psql Drops into a MySQL (or psql) shell on a database service
lando php Runs php commands
Usage examples
# Download a dependency with drush
lando composer require phpunit/phpunit --dev
# Run composer tests
lando db-import dump.sql.gz
# Drop into a mysql shell
lando mysql
# Check hte app's installed php extensions
lando php -m
You can also run lando
from inside your app directory for a complete list of commands. This is always advisable as your list of commands may not be 100% the same as above. For example, if you set database: postgres
you will get lando psql
instead of lando mysql
.
