mongo快速搭建复制集

第一步：

在D:\MongoDB目录建立3个目录：conf(保存配置文件夹)、data(保存数据文件夹）、log(保存日志文件夹)

第二步：

在data文件夹下分别建rs1,rs2,rs3(分别保存primary，secondary,arbiter服务器的数据)

第三步：

在conf文件夹下建立rs1.conf,rs2.conf,rs3.conf配置文件

rs1的内容：

1. dbpath=D:\MongoDB\data\rs1
2. logpath=D:\MongoDB\log\rs1.log
3. journal=true
4. port=40000
5. replSet=rs0

rs2的内容：

1. dbpath=D:\MongoDB\data\rs2
2. logpath=D:\MongoDB\log\rs2.log
3. journal=true
4. port=40001
5. replSet=rs0

rs3的内容：

1. dbpath=D:\MongoDB\data\rs3
2. logpath=D:\MongoDB\log\rs3.log
3. journal=true
4. port=40002
5. replSet=rs0

第四步：

以用conf的方式启动mongod服务

下面的3条命令分别在3个命令行中执行

1. mongod --config D:\MongoDB\conf\rs1.conf
2. mongod --config D:\MongoDB\conf\rs2.conf
3. mongod --config D:\MongoDB\conf\rs3.conf

第五步：

登录3个服务器

下面3条命令分别在3个命令行中执行

1. mongo --port 40000
2. mongo --port 40001
3. mongo --port 40002

第六步：

在40000端口对应的客户端上依次执行如下命令

1. rs.initiate()
2. rs.conf()
3. rs.add("DESKTOP-MNG19L3:40001")
4. rs.addArb("DESKTOP-MNG19L3:40002")
5. rs.status()

运行的结果如下：

1. > rs.initiate()
2. {
3. "info2":"no configuration specified. Using a default configuration for the set",
4. "me":"DESKTOP-MNG19L3:40000",
