使用jodis报错，很奇怪，用命令行连接codis写入操作没有问题

使用jodis报错，很奇怪，用命令行连接codis写入操作没有问题

[Apache9]

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]

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

[Apache9]

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？

[wy1981105]

@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

[spinlock]

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]

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]

@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]

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]

3q,已经解决。

[spinlock]

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"
