Memcached缓存集群_创建多实例

1.首先在在服务端增加两个缓存实例，如192.168.120.101:11214和192.168.120.102:11215,空间分配可按实际需求定。

2.JAVA客户端导入

3.缓存集群配置：memcached11212.xml

<?xml version="1.0" encoding="UTF-8"?>
<memcached>

    <client name="mclient0" compressEnable="true" defaultEncoding="UTF-8" socketpool="pool0">
        <errorHandler>com.alisoft.xplatform.asf.cache.memcached.MemcachedErrorHandler</errorHandler>
    </client>

    <client name="mclient1" compressEnable="true" defaultEncoding="UTF-8" socketpool="pool1">
        <errorHandler>com.alisoft.xplatform.asf.cache.memcached.MemcachedErrorHandler</errorHandler>
    </client>

    <socketpool name="pool0" failover="true" initConn="5" minConn="5" maxConn="5000" maintSleep="0"
        nagle="false" socketTO="36000" aliveCheck="true">
        <servers>192.168.120.101:11214</servers>
    </socketpool> 

    <socketpool name="pool1" failover="true" initConn="5" minConn="5" maxConn="5000" maintSleep="0"
        nagle="false" socketTO="36000" aliveCheck="true">
        <servers>192.168.120.102:11215</servers>
    </socketpool> 

    <cluster name="cluster1" mode="active"> <!--mode = active,standby-->
        <memCachedClients>mclient0,mclient1</memCachedClients>
    </cluster>

</memcached>

memcached11212.xml

4.写工具类操作缓存

package com.zqgame.adreport.front.memcached;

import java.util.Date;

import com.alisoft.xplatform.asf.cache.IMemcachedCache;
