java操作redis cluster叢集可使用jredis

php要操作redis cluster叢集有兩種方式：

1、使用phpredis擴充套件，這是個c擴充套件，效能更高，但是phpredis2.x擴充套件不行，需升級phpredis到3.0，但這個方案參考資料很少

2、使用predis，純php開發，使用了名稱空間，需要php5.3+，靈活性高

下載好後重命名為predis，

server1：192.168.1.198
server2：192.168.1.199

predis.php

<?php
require 'predis/autoload.php';//引入predis相關包
//redis例項
$servers = array(
    'tcp://192.168.1.198:7000',
    'tcp://192.168.1.198:7001',
    'tcp://192.168.1.198:7002',
    'tcp://192.168.1.199:7003',
    'tcp://192.168.1.199:7004',
    'tcp://192.168.1.199:7005',
);

$client = new Predis\Client($servers, array('cluster' => 'redis'));

$client->set("name1", "11");
$client->set("name2", "22");
$client->set("name3", "33");

$name1 = $client->get('name1');
$name2 = $client->get('name2');
$name3 = $client->get('name3');
var_dump($name1, $name2, $name3);die;
?>
 

首先執行predis.php檢視結果：

然後登入到redis客戶端進行叢集驗證：

server1

[[email protected] src]# redis-cli -c -p 7000
127.0.0.1:7000> get name1
-> Redirected to slot [12933] located at 192.168.1.199:7004
"11"
192.168.1.199:7004> get name2
-> Redirected to slot [742] located at 192.168.1.199:7003
"22"
192.168.1.199:7003> get name3
"33"
192.168.1.199:7003>
 

[[email protected] src]# redis-cli -c -p 7003
127.0.0.1:7003> get name1
-> Redirected to slot [12933] located at 192.168.1.199:7004
"11"
192.168.1.199:7004> get name2
-> Redirected to slot [742] located at 192.168.1.199:7003
"22"
192.168.1.199:7003> get name3
"33"
192.168.1.199:7003>

可以看到資料分佈在各個伺服器上，可以根據ps -ef | grep redis，殺掉其中幾個redis例項，再看效果
