EZP-25972: Clustering guide improvement #443
Conversation
| Memcached must not be bound to the local address if clusters are in use, or user logins will fail. | ||
| To avoid this, in `/etc/memcached.conf` take a look under `# Specify which IP address to listen on. The default is to listen on all IP addresses` | ||
| - [Solr](solr.md) for better search and performance | ||
| - a CDN for improved performance and faster ping time worldwide |

| > Listen on <addr>; default to INADDR\_ANY. <addr> may be specified as host:port. If you don't specify a port number, the value you specified with -p or -U is used. You may specify multiple addresses separated by comma or by using -l multiple times. This is an important option to consider as there is no other way to secure the installation. Binding to an internal or firewalled network interface is suggested. | ||

rather link to our doc (persistence cache), as we might introduce own adapters soon that improve performance.
Align this with the link done on memcached, so both initial section on Redis links to persistence cache doc, as well as the alternative section.

skip, it will change, lets not duplicate please
At least it looks strange to have config for Redis here, but config for all others the other place.

| To clear it, use a dedicated Symfony command: `php bin/console cache:pool:clear cache.redis`. | ||

This can make sense to have here, but then we should rewrite it to more clearly cover both sessions and persistence cache topics. and link to it
|
@DominikaK I think I see what you are trying to do => write a guide to setting up a (specific) cluster setup. Wouldn't it be better to continue letting this be general doc landing page for cluster where we document all possibilities, and write a separate guide / tutorial page where we guide how a specific setup is accomplished? |
|
@andrerom you're right, let's go it slowly and resolve this ticket first, then we can plan for extending the doc on clustering in future. |

| [Redis](http://redis.io/), an in-memory data structure store, is the recommended cache solution for clustering. | ||
| Redis is used via [Redis pecl extension](https://pecl.php.net/package/redis). | ||
|
|
||
| An alternative cache solution for cluster setups is [using Memcached](persistence_cache.md#memcached). |

not needed here, memcached is explained further down and this is section dedicated to redis
Reorganizes sections as suggested in ticket description.
This is a second attempt at #428, which got too many conflicts after #418
