For Linux

1. 下载memcached-1.2.1.tar.gz和libevent-1.3b.tar.gz

# wget http://www.danga.com/memcached/dist/memcached-1.2.5.tar.gz
# wget http://www.monkey.org/~provos/libevent-1.3.tar.gz

2. 安装libevent

# tar xvfz  libevent-1.3.tar.gz

# cd libevent-1.3

# ./configure --prefix=/usr

# make & make install

#　ls -al /usr/lib | grep libevent

3. 安装 memcached

# tar xvfz  memcached-1.2.5.tar.gz

#  cd  memcached-1.2.5

# ./configure --with-libevent=/usr

#  make & make install

#  ls -al /usr/local/bin/mem*

4. 將 libevent 安裝的/usr/local/lib 輸出到涵式庫路徑

# vi ~/.bash_profile

add the following sentence

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

5.  啟動 memcached: /usr/local/bin/memcached

# memcached  -d  -m 128 -l 192.168.152.143 -p 11211 -u root
