好久裝一次memcached，每次再裝都愛忘，做個筆記！
軟件下載地址：
libevent-2.1.4-alpha.tar.gz http://down.51cto.com/data/1985855
memcached-1.4.21.tar.gz http://down.51cto.com/data/1975956
1. libevent是安裝 memcached的唯一前提條件。它是 memcached 所依賴的異步事件通知庫。
# yum -y install gcc //安裝libevent需要gcc
# tar zxf libevent-2.1.4-alpha.tar.gz
# cd libevent-2.1.4-alpha
# ./configure
# make
# make install
2.安裝啓動memcached
# tar zxf memcached-1.4.21.tar.gz
# cd memcached-1.4.21
# ./configure
# make && make install
# which memcached
啓動測試時找不到共享庫libevent-2.1.so.4
# whereis libevent-2.1.so.4
# cp /usr/local/lib/libevent-2.1.so.4 /usr/lib
# ldconfig
3. 啓動腳本
# cat /data/shell/memcached.sh
#!/bin/sh
# memcached:MemCached Daemon
# chkconfig: - 90 25
