nixn/etcdsh

A PHP session handler, which stores the session data in an ETCD cluster and enables automatic cleaning of sessions with ETCD's lease system.

It uses the PHP session lifetime (session.gc_maxlifetime) for the data, which enables automatic cleaning of the session data after session timeout - with no interaction from the application side (like CRON jobs or the like).

Due to the nature of ETCD it is possible to have multiple web servers, which all access the same session data, so possibly session stickiness could be rethought…

Setup

Installation

etcdsh uses the Aternos gRPC ETCD client, which needs the extension php-grpc.

apt install php-grpc
composer require nixn/etcdsh

Usage

use nix\etcdsh\EtcdSessionHandler;
use Aternos\Etcd\Client as EtcdClient;

session_name('MY_SESSION_NAME'); // recommended to set, default is PHPSESSID
session_set_save_handler(new EtcdSessionHandler(new EtcdClient('localhost')));
session_save_path('sessions/'); // used as prefix in ETCD ("<name>/<id>:<lease-id>" appended)
ini_set('session.gc_probability', 0); // GC not needed with EtcdSessionHandler
ini_set('session.gc_maxlifetime', 1440); // set lifetime to your liking
session_start();

NOTE: The package name is nix\etcdsh, not nixn\etcdsh.
