Issue with redis backend cache and Lesti #297

Closed vhanahrni closed 7 years ago

vhanahrni commented 7 years ago

I get this error : 

 Connection to Redis failed after 2 failures

I have 2 redis instances , configured following this post

system – redis port 6379 fpc – redis port 6381

I have no issue when backend cache is running only,

but when Lesti is active I get this error in frontend.

While trying to refresh the cache from magento admin panel, I get the same error, and in error log i have

AH01797: client denied by server configuration: /var/www/vhosts/domain.com/httpdocs/magento_folder/app/etc/local.xml

What do you think ?

local.xml and fpc.xml are configured like this :

local.xml :

    <cache>

            <!--persistent>1</persistent--> <!-- persistence value, 0: not in use, > 0 used as persistence ID -->
        </backend_options>
    </cache>

Hello @vhanahrni I am no expert on this topic, but the error of your logs is a Apache error and I am not sure if that is really the reason of your problem. Maybe related I would say. What does telnet localhost 6381 as mentioned in Magento REDIS : system, session and full page cache management solution say?

Hello, and thanks for your quick comment.

For an attempt to load the home page I get :

I have no clue what all that stuff is, but that looks like session stuff. Pretty similar to Monitor Magento redis session cache.

Have you tried something like Magento-Redismanager?

vhanahrni commented 7 years ago

I removed the multiple instances conf to go back to only one on 6379. Then enable lesti whith no issue. does your socket handle multiple port ?

rafaelpatro commented 7 years ago

No. I don't know whether ports are used or not when connected by socket. But I use multiple databases through socket connection with no issues.

vhanahrni commented 7 years ago

ok thanks. we can close.
