mongo设置集

1.基本信息如下

服务器地址 192.168.73.129

副本集名称 rs

容器节点及端口映射

m0 37017:27017

m1 47017:27017

m2 57017:27017

注：机器环境安装docker

2.部署步骤

2.1下载mongo镜像

docker pull mongo

2.2 启动三个节点

docker run --name m0 -p 37017:27017 -d mongo --replSet "rs"

docker run --name m1 -p 47017:27017 -d mongo --replSet "rs"

docker run --name m2 -p 57017:27017 -d mongo --replSet "rs"

docker ps -a //查看启动的容器

2.3 连接任意一个节点，进行副本集配置

进入其中一个容器：docker exec -it de242cc5fa5a /bin/bash

连接三个节点中的任意一个,注意ip地址为宿主机ip,我当前的为192.168.73.129

mongo --host 192.168.73.129 --port 37017

此时已连接到m0节点，进行副本集配置

var config={
     _id:"rs",
     members:[
         {_id:0,host:"192.168.73.129:37017"},
         {_id:1,host:"192.168.73.129:47017"},
         {_id:2,host:"192.168.73.129:57017"}
]}；
rs.initiate(config)

响应应该类似下面，注意此时命令提示符已经发生变化，由原来的 > 变成了 rs:SECONDARY>

{
    "ok" : 1,
    "operationTime" : Timestamp(1522810920, 1),
    "$clusterTime" : {
        "clusterTime" : Timestamp(1522810920, 1),
        "signature" : {
            "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
            "keyId" : NumberLong(0)
        }
    }
}

2.4查看副本集配置信息
