Linux下安装Memcache

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
