Beta Branch Centmin Mod 123.09beta01 centmin.sh menu option 22 - add Redis cache support

Woohoo this is an awesome addition

 

Good news, assuming based on my feedback!

 

I'm not sure if there were any changes made other than uncommenting and installing redis for you, but I noticed xmlrpc.php is being cached now although it is set to skip_cache in rediscache_domain.com.conf

XML-RPC server accepts POST requests only.
<!--Cached using Nginx-Helper on 2016-09-24 13:14:28. It took 0 queries executed in 0.279 seconds.-->
<!--Visit Nginx Helper — WordPress Plugins for more details-->

Weird right?

This is causing issues with Jetpack

 

We just need an out of the box Varnish Cache now

 

This is a fresh OS and centmin install, was done yesterday using option 22

Hmm I think I jumped the gun on this one. Been monitoring the access logs and I am seeing no hits from Jetpack, the DNS was changed but its been over 12 hours however I am thinking Jetpack is still hitting the old server.

Jetpack doesn't give any helpful messages other than:

We were unable to make an XML-RPC request to your website. Please make sure that XML-RPC is turned on and that Jetpack is installed, activated and connected with your WordPress.com account.

Don't waste anymore time on this, my bad.

 

Well if we had an option in centminmod to install varnish we cold have it install with the default vcl and have say a wordpress vcl file and other vcl files or vcl configs commented out - Yes on top of varnish but if you use it then like ssh you should know what your doing - depends really if many have any configs, wordpress is pretty default and loads on the net about vcl for wordpress including running nginx for the ssl and then varnish as the cache (as it doesnt do ssl although i believe v5 is getting there) - i used to run on varnish using unixy's vcl flavours (paid for) and to be honest it was very good, far better than memcache and other caching methods, although never tried redis

Perhaps update the third party yum to v4 then ?

V3 is quite old now

Agree and i only have ever used it for single sites not multiples with different things running and that is where it is pretty awesome

 

@eva2000 The namespace values in src/config.php can have any name right?

In the thread it's xfaredis_
Can it be forumNameRedis_ ?
