1、安裝 EPEL Repo

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

2、安裝 Memcache
yum -y install memcached

安裝過程中可能會出現如下問題：
--> Missing Dependency: perl(Net::SSLeay) >= 1.33 is needed by package perl-AnyEvent-5.240-1.el5.rf.noarch (rpmforge)
Error: Missing Dependency: perl(Net::SSLeay) >= 1.33 is needed by package perl-AnyEvent-5.240-1.el5.rf.noarch (rpmforge)
You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.

這個問題是因為CentOS的 yum沒有memcached需要的最新的 perl-Net-SSLeay 和 perl-IO-Socket-SSL包.
解決辦法也很簡單，刪除舊的包，安裝新的包。

查看舊版本的包
rpm -qa | grep perl-Net-SSLeay
rpm -qa | grep perl-IO-Socket-SSL

移除並安裝新包
rpm-e perl-Net-SSLeay-1.30-4.fc6
rpm -e perl-IO-Socket-SSL-1.01-1.fc6
wget http://packages.sw.be/perl-Net-SSLeay/perl-Net-SSLeay-1.36-1.el5.rfx.i386.rpm
wget http://packages.sw.be/perl-Net-SSLeay/perl-Net-SSLeay-1.36-1.el5.rfx.x86_64.rpm
wget http://packages.sw.be/perl-IO-Socket-SSL/perl-IO-Socket-SSL-1.34-1.el5.rfx.noarch.rpm
rpm -i perl-Net-SSLeay-1.36-1.el5.rfx.x86_64.rpm
rpm -i perl-Net-SSLeay-1.36-1.el5.rfx.i386.rpm
rpm -i perl-IO-Socket-SSL-1.34-1.el5.rfx.noarch.rpm

然後再執行安裝命令
yum -y install memcached

即可安裝成功

3、設定為開機啟動
chkconfig --level 2345 memcached on

4、啟動和停止
/etc/init.d/memcached start|stop
