Linux下Memcached-1.4.10安裝

memcache是一款流行的緩存產品，它分爲兩個部分：一個是運行在服務器端的memcached進程，一個是在客戶端進行調用獲取緩存中數據客戶端，例如比較經常使用的PHP客戶端。這裏，記錄一下安裝服務器端的memcached的過程，比較容易。

 

準備軟件包 

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

安裝配置

安裝libevent-2.0.16

安裝libevent-2.0.16的過程以下所示（注意，安裝須要root帳戶權限）：

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

安裝完成之後，經過下面的方式來驗證是否安裝成功：

root@ www.linuxidc.com:/usr/local# ls -al  /usr/local/lib | grep libevent

安裝memcached-1.4.10

一、安裝memcached-1.4.10的過程，以下所示：

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

二、測試memcached-1.4.10安裝是否成功：

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

啓動memcached服務：

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

執行上面的命令行，將啓動memcached服務進程，而且進程號存儲在/tmp/memcached.pid文件中。

上述命令行中選項的含義簡介以下：

 

• -d  指定memcached進程做爲一個守護進程啓動
• -m  指定分配給memcached使用的內存，單位是MB
• -u  指定運行memcached的用戶
• -l  指定監聽的服務器IP地址，若是有多個地址的話，使用逗號分隔，格式能夠爲「IP地址:端口號」，例如：-l 192.168.0.184:19830,192.168.0.195:13542；端口號也能夠經過-p選項指定
• -p  指定memcached監聽的端口，要保證該端口號未被佔用
• -c  指定是最大運行的併發鏈接數，默認是1024
• -P  指定保存memcached進程的pid文件

 

Java 測試代碼：

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);
	}
