php - Memcached Invalid User -

i have server running centos.

i used guide http://www.if-not-true-then-false.com/2010/install-memcached-on-centos-fedora-red-hat/ install it. says it's installed , everything, when type in

# /etc/init.d/memcached start 

i error:

starting memcached: chown: 'memcached\r': invalid user    switch toe user memcached 

i have googled everywhere , can't find answer.

anyone have advice?

thank you!

looks memcached user not available on system, confirm can run:

$ -> id memcached uid=497(memcached) gid=497(memcached) groups=497(memcached) 

if don't see similar reponse, need add user/group:

$ -> groupadd memcached $ -> useradd -g memcached -d /dev/null -s /sbin/nologin 

now should see response similar to:

$ -> id memcached uid=497(memcached) gid=497(memcached) groups=497(memcached)
