=== 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:
<sxh bash>
netstat -plnt | grep redis
</sxh>
Output will look similar to:
<sxh bash>
tcp        0      0 10.x.x.26:6379          0.0.0.0:*                   LISTEN      5972/redis-server 1 
</sxh>
\\
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
<sxh bash>
grep -i password path/to/document/root/app/etc/local.xml
</sxh>
Ouput will look like:
<sxh bash>
                    <password><![asjpAJSPAkspaks]]></password>
                <password>aNSLAjsAJMS;MAs;sA</password> 
</sxh>
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
<sxh bash>
telnet 10.x.x.26 6379
</sxh>
Run the command INFO to see if you are authenticated:
<sxh bash>
INFO
</sxh>
<sxh bash>
-NOAUTH Authentication required.
</sxh>
Now authenticate with the password:
<sxh bash>
AUTH reallylongpassword
</sxh>
Confirmation you have authenticated:
<sxh bash>
+OK
</sxh>
Now we need to flush the cache:
<sxh bash>
FLUSHALL
</sxh>

<sxh bash>
RUN INFO
</sxh>
