【问题描述】：

我目前有一个包含两个节点的工作集群。以下是/etc/aerospike/aerospike.conf的内容——

network {
    service {
        address any
        port 3000
    }
    heartbeat {
        mode mesh
        port 3002 # Heartbeat port for this node.
        # List one or more other nodes, one ip-address & port per line:

                mesh-seed-address-port <existing server's ip> 3002

                mesh-seed-address-port <other server's ip> 3002


        interval 250
        timeout 10
    }
    fabric {
        port 3001
    }
    info {
        port 3003
    }
}

我尝试通过删除另一个节点的地址端口来更改心跳设置 -

heartbeat {
            mode mesh
            port 3002 # Heartbeat port for this node.
            # List one or more other nodes, one ip-address & port per line:

                    mesh-seed-address-port <existing server's ip> 3002

            interval 250
            timeout 10
        }

然后我重新启动了 aerospike 和 amc 服务 -

service aerospike restart
service amc restart

但是，/var/log/aerospike/aerospike.log 文件仍然显示存在两个节点 -

AMC 控制台也是如此。

【问题讨论】：

对了，如何查看aerospike的版本？找不到命令。
asinfo -h "HOST.IP" -v "版本"

标签： aerospike

【解决方案1】：

这应该会有所帮助：http://www.aerospike.com/docs/operations/manage/cluster_mng/removing_node

一旦节点被正确删除，您可以使用不同的心跳配置重新启动它，这样它就不会加入另一个节点。

对于版本，只需执行asd --version。你也可以使用asinfo -v build。

版本也打印在 asadm / AMC 和启动时的日志中。
