This PR implements Redis session manage.
It works with redis server in TCP or Unix Socket.
Test Instructions
- Install Redis server.
- Install Redis PHP pecl.
- Configure Redis server with tcp and/or unix socket.
redis.conf example for only TCP:
port 6379
redis.conf example for only Unix Socket:
port 0
unixsocket /var/run/redis/redis.sock
unixsocketperm 777
redis.conf example for TCP and Unix Socket:
port 6379
unixsocket /var/run/redis/redis.sock
unixsocketperm 777
- Restart redis and php services
- Check if redis is accepting connections
For TCP: redis-cli ping
For Unix Socket: redis-cli -s /var/run/redis/redis.sock ping
- Download joomla staging + redis session https://github.com/andrepereiradasilva/joomla-cms/archive/staging.zip
- Configure redis session manager in global configuration
For TCP:
Host: Redis server ipv4 or localhost or domain (ex: localhost)
Port: Redis server port (ex: 6379)
Persist: Yes or No
Auth: Empty or password
Database: integer
For Unix Socket:
Host: Redis socket path (ex: /var/run/redis/redis.sock)
Port: 0 or -1
Persist: Yes or No
Auth: Empty or password
Database: integer
- Try admin and frontend login and logout
Tested in:
- CentOS Linux 7.1
- redis v2.8.19-2 (epel repository)
- php56 v5.6.9-1 (webtatic repository)
- php56 pecl redis v2.2.7-1 (webtatic repository)
- Joomla 3.4.1

This PR is not about this, but one thing important you should discuss is how to configure object/session cache handlers that are configured in clusters (for instance, for redundancy).
If you have 2 or more redis servers working in cluster, let's call it rediscluster01.local and rediscluster02.local and they have different weights, the "session.save_path" should be something like:
tcp://rediscluster01.local:6379?persistent=1&auth=passwordserver1&database=0&weight=1, tcp://rediscluster02.local:6379?persistent=1&auth=passwordserver2&database=0&weight=2But joomla global config form doesn't allow more than one server.
This is also a problem in cluster with memcache, memcached, etc, not only redis.
I see two solutions for this:
1. Revision of the object/session cache handlers code to allow multiple servers
2. For each object/session cache handlers that allow multiservers, add a new text form field, for instance, "Custom", by default empty, where the user could write the string like the one above that would overwrite all config setting for the object/session cache handler in question.
IMHO this is an option because who needs to configure a object/session cache cluster is an advanced user and knows how to do this.
Of course since i don't have a full knowledge how joomla works you should know better if this makes sense.
