码头上的多个aerospike节点

时间:2017-04-29 22:25:02

标签: docker aerospike

我想拥有一个aerospike服务器节点的多个实例,所以负载平衡因为我遇到了这么多请求的服务器我收到错误说“错误代码22:此时操作不允许”#39;

我假设有更多的aerospike服务器节点可以减轻一个节点的负载,从而完成更多的操作?我不知道从哪里开始。

我在一台主机上本地需要这些节点。任何帮助都会很棒。

我的网络知识并不是很好,所以请原谅我

我的DockerFile:

FROM aerospike/aerospike-server

MAINTAINER "xxxx"

ADD aerospike.conf /etc/aerospike/

搬运工-compose.yml

version: "3"

services:
   aerospike-server:
      image: amc
      container_name: aerospike-server
      ports:
      - "3000:3000"
      - "3001:3001"
      - "3002:3002"
      - "3003:3003"
   aerospike-amc:
      image: mrbar42/aerospike-amc
      container_name: aerospike-amc
      ports:
      - "8081:8081"

aerospike.conf network stanza

network {
    service {
        address any
        port 3000

        # Uncomment the following to set the `access-address` parameter to the
        # IP address of the Docker host. This will the allow the server to correctly
        # publish the address which applications and other nodes in the cluster to
        # use when addressing this node.
        # access-address <IPADDR>
    }

    heartbeat {

        # mesh is used for environments that do not support multicast
        mode mesh
        port 3002

        # use asinfo -v 'tip:host=<ADDR>;port=3002' to inform cluster of
        # other mesh nodes
        interval 150
        timeout 10
    }

    fabric {
        # address any
        port 3001
    }

    info {
        # address any
        port 3003
    }
}

您可以使用多播心跳配置,并在一台计算机上运行一小群aerospike节点。

以下是我使用的步骤:

1)从aerospike repo获取最新的Dockerfile

git clone https://github.com/aerospike/aerospike-server.docker.git

2)修改心跳部分并使用multicast:

    heartbeat {

            mode multicast
            multicast-group 239.1.99.2
            port 9918

            interval 150
            timeout 10
    }

3)使用docker-compose或自定义脚本构建映像和集群。

我使用了以下自定义makecluster.sh bash shell脚本:

cat makecluster.sh 
docker build -t "aerospike/aerospike-server" .
for i in {3..9} ; do
echo $i;
docker stop aerospike${i}
docker rm aerospike${i}
docker run -tid --name aerospike${i} -p ${i}000:3000 -p ${i}001:3001 -p ${i}002:3002 -p ${i}003:3003 aerospike/aerospike-server
done;

并运行:

5)验证群集信息:

使用docker exec运行asadm工具

docker exec -ti aerospike7 asadm

注意:如果在主机上的docker容器外运行,则AMC或asadm等工具可能无法查看完整群集。在这种使用案例中,您可能需要在aerospike.conf中尝试docker主机网络和不同的侦听端口,或者替代方法是在容器中运行AMC。

6)如果使用--network = host,则需要修改aerospike.conf中的监听端口。运行在具有相同IP地址的同一主机上的每个实例在使用主机网络时应使用不同的端口。

示例:

cat makecluster.sh 
docker build -t "aerospike/aerospike-server" .
for i in {6..9} ; do
echo $i;
docker stop aerospike${i}
docker rm aerospike${i}
docker run -tid --name aerospike${i} -v /root/docker/aerospike-server.docker/aerospike${i}:/etc/aerospike --network host -p ${i}000:${i}000 -p ${i}001:${i}001 -p ${i}002:${i}002 -p ${i}003:${i}003 aerospike/aerospike-server
