>cd /root/software
>wget http://memcached.org/latest
>tar -zxvf latest
>cd memcached-1.4.20
>./configure --with-libevent=/usr && make && make test && sudo make install

然后提示找不到libevent

>yum install libevent
Loaded plugins: fastestmirror

Setting up Install Process
Package libevent-1.4.13-4.el6.x86_64 already installed and latest version
Nothing to do

于是前往下载libevent.org自行下载

>cd /root/software
>wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
>tar -zxvf libevent-2.0.21-stable.tar.gz
>cd libevent-2.0.21-stable
>./configure && make && make install
>cd /root/software/memcached-1.4.20
>./configure --with-libevent=/usr && make && make test && sudo make install
./timedrun: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory

又提示错误了，应该是缺少符号链接了

>ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5
>./configure --with-libevent=/usr && make && make test && sudo make install
make: prove: Command not found

依然有错误，Google一下，再安装一个

>yum install perl-Test-Harness
>./configure --with-libevent=/usr && make && make test && sudo make install

还是有错误，错误很长，就不贴了，继续打两个perl包

>yum install perl-CPAN
>yum install perl-Test-Simple
>./configure --with-libevent=/usr && make && make test && sudo make install

很不顺利。

>yum install git
>./configure --with-libevent=/usr && make && make test && sudo make install

终于成功了！！！加入启动项
