Linux下Memcached-1.4.10安装

memcache是一款流行的缓存产品，它分为两个部分：一个是运行在服务器端的memcached进程，一个是在客户端进行调用获取缓存中数据客户端，例如比较常用的PHP客户端。这里，记录一下安装服务器端的memcached的过程，比较容易。

准备软件包

libevent-2.0.16-stable.tar.gz
memcached-1.4.10.tar.gz

安装配置

安装libevent-2.0.16

安装libevent-2.0.16的过程如下所示（注意，安装需要root账户权限）：

root@ www.linuxidc.com:/home/shirdrn# tar -xvzf libevent-2.0.16-stable.tar.gz
root@ www.linuxidc.com:/home/shirdrn# cd libevent-2.0.16-stable/
root@ www.linuxidc.com:/home/shirdrn/libevent-2.0.16-stable# ./configure
root@ www.linuxidc.com:/home/shirdrn/libevent-2.0.16-stable# make
root@ www.linuxidc.com:/home/shirdrn/libevent-2.0.16-stable# make install

安装完成以后，通过下面的方式来验证是否安装成功：

安装memcached-1.4.10

1、安装memcached-1.4.10的过程，如下所示：

root@ www.linuxidc.com:/home/shirdrn# tar -xvzf memcached-1.4.10.tar.gz
root@ www.linuxidc.com:/home/shirdrn# cd memcached-1.4.10/
root@ www.linuxidc.com:/home/shirdrn/memcached-1.4.10# ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local
root@ www.linuxidc.com:/home/shirdrn/memcached-1.4.10# make
root@ www.linuxidc.com:/home/shirdrn/memcached-1.4.10# make install

2、测试memcached-1.4.10安装是否成功：

root@ www.linuxidc.com:/usr/local# ls -al /usr/local/memcached/bin/mem*
-rwxr-xr-x 1 root root 365926 2011-12-15 14:54 /usr/local/memcached/bin/memcached

启动memcached服务：

/usr/local/memcached/bin/memcached -d -m 256 -u root -l host -p 8311 -c 5000 -P /tmp/memcached.pid

执行上面的命令行，将启动memcached服务进程，并且进程号存储在/tmp/memcached.pid文件中。

上述命令行中选项的含义简介如下：

-d 指定memcached进程作为一个守护进程启动
-m 指定分配给memcached使用的内存，单位是MB
-u 指定运行memcached的用户
-l 指定监听的服务器IP地址，如果有多个地址的话，使用逗号分隔，格式可以为“IP地址:端口号”，例如：-l 192.168.0.184:19830,192.168.0.195:13542；端口号也可以通过-p选项指定
-p 指定memcached监听的端口，要保证该端口号未被占用
-c 指定是最大运行的并发连接数，默认是1024
-P 指定保存memcached进程的pid文件

Java 测试代码：

import net.spy.memcached.MemcachedClient;

import java.net.InetSocketAddress;

public static void main(String[] args) throws IOException {

	    MemcachedClient client = new MemcachedClient(new InetSocketAddress("cq01-sdcrd-cbstat03.cq01.baidu.com", 8311));

	    client.set("testUserName", 1000, "shine");

	    Object ret = client.get("testUserName");

	    System.out.println(ret);

	}
