1.分别把memcached和libevent下载回来，放到 /tmp 目录下：

# cd /tmp

# wget http://www.danga.com/memcached/dist/memcached-1.2.0.tar.gz

# wget http://www.monkey.org/~provos/libevent-1.2.tar.gz

2.先安装libevent：

# tar zxvf libevent-1.2.tar.gz

# cd libevent-1.2

# ./configure –prefix=/usr

# make

# make install

3.测试libevent是否安装成功：

# ls -al /usr/lib | grep libevent

lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent-1.2.so.1 -> libevent-1.2.so.1.0.3

-rwxr-xr-x 1 root root 263546 11?? 12 17:38 libevent-1.2.so.1.0.3

-rw-r–r– 1 root root 454156 11?? 12 17:38 libevent.a

-rwxr-xr-x 1 root root 811 11?? 12 17:38 libevent.la

lrwxrwxrwx 1 root root 21 11?? 12 17:38 libevent.so -> libevent-1.2.so.1.0.3

还不错，都安装上了。

4.安装memcached，同时需要安装中指定libevent的安装位置：

# cd /tmp

# tar zxvf memcached-1.2.0.tar.gz

# cd memcached-1.2.0

# ./configure –with-libevent=/usr

# make

# make install

如果中间出现报错，请仔细检查错误信息，按照错误信息来配置或者增加相应的库或者路径。

安装完成后会把memcached放到 /usr/local/bin/memcached ，

5.测试是否成功安装memcached：

# ls -al /usr/local/bin/mem*

-rwxr-xr-x 1 root root 137986 11?? 12 17:39 /usr/local/bin/memcached

-rwxr-xr-x 1 root root 140179 11?? 12 17:39 /usr/local/bin/memcached-debug
