memcached安装

先安装libevent函数库
wget https://github.com/libevent/libevent/releases/download/release-2.1.10-stable/libevent-2.1.10-stable.tar.gz
tar zxvf libevent-2.1.10-stable.tar.gz
cd libevent-2.1.10-stable/
./configure --prefix=/usr/local/libevent
make && make install

安装memcached
cd ~
wget http://memcached.org/latest -O memcached.tar.gz
tar zxvf memcached.tar.gz
cd memcached-1.5.13/
./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent
make && make test
遇到如下错误可不需要处理：
/bin/sh: line 3: prove: command not found
make: *** [test] Error 127
要解决就要安装perl-Test*
make install
ln -s /usr/local/memcached/bin/memcached /usr/bin
之所在/usr/bin做软链接，是因为启动脚本中加载了functions文件，这个文件中PATH的路径是
PATH="/sbin:/usr/sbin:/bin:/usr/bin"，在这些目录中的命令才能被搜索到。或者在启动文件中使用命令的绝对路径。

配置开机启动
cp cripts/memcached.sysv /etc/init.d/memcached
chkconfig --add memcached
chkconfig memcached on
mkdir -p /var/run/memcached
/etc/init.d/memcached start
启动文件中有两个重要参数：MAXCONN=1024和CACHESIZE=64，根据需要自行调整。

查看状态：
/etc/init.d/memcached status
停止：
/etc/init.d/memcached stop
