系统:Ubuntu14
步骤:memcached依赖libevent包,我这个系统已经有了,就没有安装
安装memcached : apt-get install memcached
修改配置: vim /etc/memcached.conf 将里面的 -l 127.0.0.1注释掉(不注释代表只能本机访问)
启动memcached: /etc/init.d/memcached start
测试: telnet localhost 11211 提示 connected to memcached成功
项目中用的是xmemcached,把jar包导入项目,编写测试代码:
public static void main(String[] args) { MemcachedClientBuilder builder = new XMemcachedClientBuilder( AddrUtil.getAddresses("192.168.64.129:11211")); MemcachedClient memcachedClient = null; try { memcachedClient = builder.build(); memcachedClient.set("hello", 0, "Hello,xmemcached"); String value = memcachedClient.get("hello"); System.out.println("hello=" + value); memcachedClient.delete("hello"); value = memcachedClient.get("hello"); System.out.println("hello=" + value); } catch (MemcachedException e) { System.err.println("MemcachedClient operation fail"); e.printStackTrace(); } catch (TimeoutException e) { System.err.println("MemcachedClient operation timeout"); e.printStackTrace(); } catch (InterruptedException e) { // ignore } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { // close memcached client memcachedClient.shutdown(); } catch (IOException e) { System.err.println("Shutdown MemcachedClient fail"); e.printStackTrace(); } }
输出:略
下一步是要建立一个双机高可用的,准备用keepalived,到时候再写
