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),
