JedisResourcePool jedisPool = RoundRobinJedisPool.create()
.curatorClient("127.0.0.1:19000", 30000).zkProxyDir("/Users/lili/Documents/jodis").build();
try (Jedis jedis = jedisPool.getResource()) {
jedis.set("foo", "bar");
String value = jedis.get("foo");
System.out.println(value);
}
提示如下错误
[main-SendThread(127.0.0.1:19000)] INFO org.apache.zookeeper.ClientCnxn - Opening socket connection to server 127.0.0.1/127.0.0.1:19000. Will not attempt to authenticate using SASL (unknown error)

但是我用命令行操作
./redis-cli -h 127.0.0.1 -p 19000
127.0.0.1:19000> get ju
"xian"
127.0.0.1:19000> get ju
"xian"
127.0.0.1:19000> get ju
"xian"
是没有问题

我的zookeeper是用的是3.4.10版本
libs目录里commons-pool2-2.3 curator-client-2.9.1 curator-framework-2.9.1 curator-recipes-2.9.1 guava-16.0.1 jackson-annotations-2.8.8 jackson-core-2.8.8 jackson-databind-2.8.8 jedis-2.8.0 jsr305-1.3.9 slf4j-api-1.7.25 slf4j-simple-1.7.25 zookeeper-3.4.10 的jar包

请牛人看看

所以你19000端口上启动的是codis proxy？

curatorClient("xxx", 30000), xxx那里写的是zk的地址，不是codis proxy的地址

改成2181,但是报如下错误

那个proxyDir传的对嘛？那个是codis proxy在zk上注册的路径

echokk11 · Answer 4 · Thu Apr 13 2017 11:21:12 GMT+0800 (China Standard Time)

我也遇到这个问题 zk注册地址是 /codis3/codis-demo/proxy
JedisResourcePool jedisPool = RoundRobinJedisPool.create()
.curatorClient("x.x.x.x:2181", 30000).zkProxyDir("/codis3/codis-demo/proxy").build();
但是返回Exception in thread "main" redis.clients.jedis.exceptions.JedisException: Proxy list empty
ip地址是对的我用zkCli可以连也看到proxy下面有节点

Duo Zhang · Answer 5 · Thu Apr 13 2017 11:29:10 GMT+0800 (China Standard Time)

这是parse节点内容出错了，把那个节点里的内容贴一下？

@spinlock 这个应该是codis proxy没有打开jodis兼容导致的？

@Apache9

[zk: 127.0.0.1:2181(CONNECTED) 3] ls /codis3/codis-demo/proxy
[proxy-503d4bf48dce7b2672467e7825ed98e1]

JedisResourcePool jedisPool = RoundRobinJedisPool.create()
.curatorClient("127.0.0.1:2181", 30000).zkProxyDir("/codis3/codis-demo/proxy").build();
try (Jedis jedis = jedisPool.getResource()) {
jedis.set("foo", "bar");
String value = jedis.get("foo");
System.out.println(value);
}

在proxy.toml文件中
odis_name = "zookeeper"
jodis_addr = "127.0.0.1:2181"
jodis_timeout = "20s"
jodis_compatible = false

是这样设置的

但是运行结果是

不是。 /codis3 路径是用来做集群管理的，服务发现是 /jodis 开始的路径或者 /zk 开始的。在 jodis 项目首页 readme 写了例子。

@spinlock 需要在/目录下建立zk或者jodis目录吗
在根目录下没有发现，只有这几个目录
Applications etc
Library home
Network installer.failurerequests
System net
Users opt
Volumes private
bin sbin
cores tmp
data usr
dev var

wy1981105 · Answer 12 · Thu Apr 13 2017 13:02:52 GMT+0800 (China Standard Time)

已经解决的确需要在根目录下建立/jodis/XX的目录 xx这里是codis-demo.才能发送，接收。
请在文档里详细写明，这个含糊有点问题，还有zookeeper的jar包与服务端要保持一致等。

echokk11 · Answer 13 · Thu Apr 13 2017 13:18:55 GMT+0800 (China Standard Time)

@wy1981105 是在文件系统中建立目录还是zk下面建立啊我问题依旧

wy1981105 · Answer 14 · Thu Apr 13 2017 13:44:24 GMT+0800 (China Standard Time)

在proxy.toml文件中
odis_name = "zookeeper"
jodis_addr = "127.0.0.1:2181"
jodis_timeout = "20s"
jodis_compatible = false 要设置

echokk11 · Answer 15 · Thu Apr 13 2017 13:53:21 GMT+0800 (China Standard Time)

3q,已经解决。

王乃峥 · Answer 16 · Thu Apr 13 2017 14:02:57 GMT+0800 (China Standard Time)

两个项目的 readme 我记得都写了的。

创建了jodis目录，还是报.JedisException: Proxy list empty
[zk: localhost:2181(CONNECTED) 7] create /jodis/codis-demo/proxy "10.2.1.31:19000"
