I am trying to follow the instructions here to install Memcached on a CentOS machine, and I'm not having much luck.

The instructions say to first enable rpmforge repository as follows:

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

This appears to go OK.

Then they say to install memcached by using yum:

yum -y install memcached

This gets the download speeds of various mirror sites, then says "Setting up Install Process", and then finally "No package memcached available".

What am I doing wrong here?

EDIT: These are the contents of my /etc/yum.conf file:

root@vps-1077739-6497 [/etc/sysconfig]# cat /etc/yum.conf
exclude=apache* bind-chroot courier* dovecot* exim* filesystem httpd* mod_ssl* mysql* nsd* perl* php* proftpd* pure-ftpd* ruby* spamassassin* squirrelmail*

# Note: yum-RHN-plugin doesn't honor this.

installonly_limit = 5

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

What version of CentOS? –  Jeff Ferland Dec 20 '11 at 17:57
Maybe snagging from RPMForge would be an option? pkgs.repoforge.org/memcached just download the rpm and install. –  Tim Dec 20 '11 at 18:08
@jeff-ferland, My version of CentOS is 5.7. –  Tola Odejayi Dec 20 '11 at 18:16
@tim, thanks for your suggestion - I'll give that a go. –  Tola Odejayi Dec 20 '11 at 18:16

Memcached is in the rpmforge-extras repository and it is not enabled by default.

 memcached                              i386                         1.4.7-1.el5.rfx                         rpmforge-extras                        79 k

You need to edit the file /etc/yum.repos.d/rpmforge.repo and put "enabled = 1" instead of "enabled = 0" in the [rpmforge-extras] section and then re-run your command yum -y install memcached.

Your /etc/yum.repos.d/rpmforge.repo should looks like this:

### Name: RPMforge RPM Repository for RHEL 5 - dag
### URL: http://rpmforge.net/
name = RHEL $releasever - RPMforge.net - dag
baseurl = http://apt.sw.be/redhat/el5/en/$basearch/rpmforge
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

name = RHEL $releasever - RPMforge.net - extras
baseurl = http://apt.sw.be/redhat/el5/en/$basearch/extras
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge-extras
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-extras
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

name = RHEL $releasever - RPMforge.net - testing
baseurl = http://apt.sw.be/redhat/el5/en/$basearch/testing
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge-testing
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge-testing
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

Just for information I reproduce the case before answering on a OpenVZ VPS with your exact command –  drivard Dec 20 '11 at 18:49
I am marking your response as the answer because it removed the issue I was having. Unfortunately, I ran into dependency issues with libevent and various Perl modules, and in the end I had to download/compile the source. These are the links I followed (in case anyone else ever has this problem): mrphp.com.au/code/install-memcache-cpanel-running-centos and alexle.net/archives/tag/libevent. The versions referred to in the links are out of date, so whoever is following the instructions should get the latest versions at the Memcached and Libevent sites. –  Tola Odejayi Dec 20 '11 at 20:14

It's hard to say what you're doing wrong. According to http://rpm.pbone.net/index.php3, RHEL5 and CentOS 6 (among others) provide memcached. CentOS5 has it in the testing branch. Perhaps if you're stuck, searching for "memcached" there for your distro will allow you a direct download that works.
