  • zookeeper集群搭建Exception when following the leader java.io.EOFException

    zk配置后集群选举失败,集群中全部无法进行选举,但是应用又起来了。

    先讲原因:后经人指点,server的端口配置错误导致。server占用了client的端口号导致的。说明server.1=127.0.0.1:2181:3181中2181是server端口但是我又配置了clientPort=2181.把server端口和client端口混为一谈导致的(汗颜并吐槽:zk既然配置错误了,就不应该让项目启动成功,应该直接停止程序或者直接报错)。

    修改zoo.cnf中集群错误配置:

    server.1=127.0.0.1:2181:3181
    server.2=127.0.0.1:2182:3182
    server.3=127.0.0.1:2183:3183

    为正确配置:

    server.1=127.0.0.1:2888:3888
    server.2=127.0.0.1:2889:3899
    server.3=127.0.0.1:2890:3890

    用zkServer.sh status的状态命令查看如下:
