nginx Digest, Vol 2, Issue 76

[Danny Trinh]

Hello Maxim,
I found another link and installed memcached. Now I see 127.0.0.1:11211
is listening.
Sorry, my mistake due to "multitasking: watching football
cowboy-vie-redskin, and doing work" ;-)

Would you please give me your opinion about this setup? Just want to
find the correct setup for my system.
Would you give some hint so I can continue with nginx using  memcache?
If you think it's necessary, please send me to my email dtrinh at
eastonbellsports dot com.
Thanks,

Danny Trinh
Linux Admin

Yes, you are.  nginx doesn't listen, it connects to memcached 
server which should listen on ip:port you specified.  It is up to 
you to start memcached and place appropriate data into it.

Also, you probably want to know that on modern operating 
systems it is usually bad idea to place files into memory 
explicitly.  Virtual memory subsystem will do it automatically as 
long as you have spare memory on your server, and will likely do 
it better than may be done by hand.

Other points in the post you linked are... uhm, questionable too 
(you may want to read "incorrect" here, but I'm not going to 
argue).  You probably want to disregard this post instead of 
following it.
