mogodb 同步数据到 ElasticSearch

1、需安装：mogodb  ElasticSearch monstache

2、mogodb创建副本集

主副主开启副本集设置：

replication:
replSetName: "S1"

副机关闭防火墙，设置

net:
port: 27017
bindIp: 0.0.0.0

"C:\Program Files\MongoDB\Server\4.4\bin\mongo.exe" 127.0.0.1:27017

配置：

rs.initiate( {

... _id : "S1",
... members: [
... { _id: 0, host: "192.168.1.239:27017" },
... { _id: 1, host: "192.168.1.253:27017" }, ]
... })

 

提示成功：{

"ok" : 0,
"errmsg" : "Our set name did not match that of the request target, requestTarget:192.168.1.253:27017",
"code" : 103,
"codeName" : "NewReplicaSetConfigurationIncompatible"
}

 在monstache根目录my.con 配置：

# mongo连接串
mongo-url = "mongodb://127.0.0.1:27017"
# ES地址
elasticsearch-urls = [ "http://localhost:9200" ]

# mydb中completed_food_orders这个collection已经有数据
# 需要先将已有数据全量导到ES中
direct-read-namespaces = ["qqqun.group2"]

# 配置collection和es索引的对应关系
[[mapping]]
namespace = "qqqun.group2"
index = "group2"

#####配置结束

执行命令：monstache.exe -f my.conf
