Flushing Redis Cache

To flush redis cache without restarting the service, follow this guide

First find out what port + IP address redis is running on:

        
              netstat -plnt | grep redis

Output will look similar to:

        
              tcp        0      0 10.x.x.26:6379          0.0.0.0:*                   LISTEN      5972/redis-server 1

You will first need to get the password from the local.xml file in the document root.
The format is normally path/to/document/root/app/etc/local.xml

        
              grep -i password path/to/document/root/app/etc/local.xml

Ouput will look like:

        
                  <password><![asjpAJSPAkspaks]]></password>
<password>aNSLAjsAJMS;MAs;sA</password>

Password you normally need is the second one. If you less the file instead you can check for the CDATA[memcache] section.
Now we need to telnet using the information from the netstat grep

        
              telnet 10.x.x.26 6379

Run the command INFO to see if you are authenticated:

        
              INFO

        
              -NOAUTH Authentication required.

Now authenticate with the password:

        
              AUTH reallylongpassword

Confirmation you have authenticated:

+OK

Now we need to flush the cache:

        
              FLUSHALL

        
              RUN INFO
