That vb.com guide is what I already used. I already pasted earlier the output to show memcached is running. I installed all 3: libevent, memcache, memcached and recompiled apache via Easy apache, restarted httpd before/after, etc.
Code:
root@server [~]# php -i | grep -i 'memcache'
OLDPWD => /root/memcache-3.0.2
_SERVER["OLDPWD"] => /root/memcache-3.0.2
_ENV["OLDPWD"] => /root/memcache-3.0.2
Code:
root@server [~]# ps aux | grep memcached
root 4823 0.0 0.0 5024 736 pts/0 S+ 20:55 0:00 grep memcached
nobody 27945 0.0 0.0 2896 836 ? Ss 16:06 0:00 /usr/local/bin/memcached -u nobody -d -m 2048 -l 127.0.0.1 -p 11211
