Should I do something or simply ignore it?

I'm using vultr's $5 VPS.

Yes I followed your instructions for installing Redis.

Code (Text):

yum -y install redis --enablerepo=remi --disableplugin=priorities
chkconfig redis on
service redis start

I skipped the following 2 steps though because it's for CentOS 6 / order version of centmin?

Code (Text):

vm.overcommit_memory = 1

Code (Text):

sysctl -p

Then I finished the following steps:

Code (Text):

maxmemory 100mb
maxmemory-policy allkeys-lru
maxmemory-samples 10

Code (Text):

appendonly yes

Code (Text):

#save 900 1
#save 300 10
#save 60 10000

Code (Text):

ervice redis restart

The two commands' output follows:

I just did the following:



and then restarted redis service. How do I check whether the warning is gone?

 

Yes seems the warning message is gone!

I just installed Xon's Redis Cache By Xon

Do need to do anything?

My forums should be much faster now?
