memcached配置

首先是安装libevent库，执行如下的命令

tar vzxf libevent-2.0.21-stable.tar.gz

cd libevent-2.0.21-stable

./configure --prefix=/usr/local/libevent-2.0.21 

make && make install

echo '/usr/local/libevent-2.0.21/lib'>> /etc/ld.so.conf.d/user-defined.conf

ldconfig

之后是安装memcached可执行文件

tar -xvf memcached-1.4.15.tar.gz

cd memcached-1.4.15

./configure --prefix=/usr/local/memcached-1.4.15 --with-libevent=/usr/local/libevent-2.0.21

make && make install

最后，安装php的memcached插件所需的libmemcached库

tar -xvf libmemcached-1.0.2.tar.gz

cd libmemcached-1.0.2 

./configure --prefix=/usr/local/libmemcached-1.0.2  --with-memcached=/usr/local/memcached-1.4.15/bin --with-libevent-prefix=/usr/local/libevent-2.0.21

make && make install

echo '/usr/local/libmemcached-1.0.2/lib'>>/etc/ld.so.conf.d/user-defined.conf

ldconfig

最后是配置memcached，

useradd www -d /data/www

cd /usr/local/memcached-1.4.15

mkdir etc

touch etc/memcached

cd /etc/init.d/

touch memcached

chmod +x memcached

在/usr/local/ memcached-1.4.15/etc/ memcached中添加如下的内容

PORT="11211" #连接端口

USER="www" #执行用户

MAXCONN="1024" #最大连接数

CACHESIZE="64" #内存大小

OPTIONS="-l 127.0.0.1" #其他的所有可用参数可以写在这里

在/etc/init.d/memcached文件中的内容，可以从源码包的conf文件夹中获取，记得需要赋予可执行权限。配置之后就可以通过service memcached start启动服务。
