Mongdb 3.2 复制集配置 官方默认配置 无认证 Windows环境

步骤：

1、更新hosts文件

路径：C:\Windows\System32\drivers\etc

在hosts文件里添加：

127.0.0.1    mongodb1.example.net
127.0.0.1    mongodb2.example.net

2、添加文件夹

路径：D:\MongoDB\data

添加3个文件夹db26001，db26002，db26003

3、启动mongod

启动实例1

mongod --port 26001 --dbpath D:\MongoDB\data\db26001\ --replSet "rs0"

4、进入实例1

mongo --port 26001

运行语句：

 rs.initiate()

返回结果：

{
        "info2" : "no configuration specified. Using a default configuration for the set",
        "me" : "CNZBNGCFTP:26001",
        "ok" : 1
}

5、

运行语句：

rs.conf()

返回结果：

{
        "_id" : "rs0",
        "version" : 1,
        "protocolVersion" : NumberLong(1),
        "members" : [
                {
                        "_id" : 0,

                },
                "replicaSetId" : ObjectId("5866046950b37ba72065b64d")
        }
}

6、

启动实例2：

mongod --port 26002 --dbpath D:\MongoDB\data\db26002\ --replSet "rs0"

在实例1主窗口运行：

运行语句：

rs.add("mongodb1.example.net:26002")

7、

运行语句：

rs.add("mongodb2.example.net:26003")

8、

运行语句：

rs.status()

{
        "set" : "rs0",
        "date" : ISODate("2016-12-30T06:59:20.351Z"),
        "myState" : 1,
        "term" : NumberLong(1),
        "heartbeatIntervalMillis" : NumberLong(2000),
        "members" : [
                {
                        "_id" : 0,
                        "name" : "CNZBNGCFTP:26001",
                        "health" : 1,

                        "optime" : {
                                "ts" : Timestamp(1483081136, 1),
                                "t" : NumberLong(1)
                        },
                        "optimeDate" : ISODate("2016-12-30T06:58:56Z"),
                        "electionTime" : Timestamp(1483080809, 2),
                        "electionDate" : ISODate("2016-12-30T06:53:29Z"),
                        "configVersion" : 3,
                        "self" : true
                },
                {
                        "_id" : 1,
                        "name" : "mongodb1.example.net:26002",
                        "health" : 1,

                        "pingMs" : NumberLong(1),
                        "configVersion" : 3
                }
        ],

9、验证复制集是否连通

进入实例3（从节点）：

mongo --port 26003

运行：

 db.testcol123.insert({a1:111})

返回：

WriteResult({ "writeError" : { "code" : 10107, "errmsg" : "not master" } })

//从节点不能写入

--添加数据，测试是否传到从节点

进入实例1：

mongo --port 26001

运行：

 db.testcol123.insert({a1:111})

返回：

WriteResult({ "nInserted" : 1 })

查看实例2，实例3

运行语句：

 rs.slaveOk()

 db.testcol123.find()

返回：{ "_id" : ObjectId("586606af88a8a8ddaf1dc3ad"), "a1" : 111 }

//已经传入从节点
