本文档详述了如何在本地环境中配置MongoDB复制集。首先，创建并启动三个配置文件来代表复制集的不同节点，然后在其中一个节点上通过客户端设置复制集，并使用特定命令检查配置结果。

本机测试搭建Mongo复制集

首先创建三个配置文件

# mongo1.conf
logpath=/tmp/logs.log1.txt
dbpath=/data/db
port=27017
fork=true
logappend=true
replSet=wukai/127.0.0.1:27018

# mongo2.conf   
logpath=/tmp/logs/log2.txt
dbpath=/data/db2
port=27018
fork=true
logappend=true
replSet=wukai/127.0.0.1:27017

# mongo3.conf
logpath=/tmp/logs.log3.txt
dbpath=/data/db3
port=27019
fork=true
logappend=true
replSet=wukai/127.0.0.1:27017,127.0.0.1:27018

分别启动这三个数据库

./mongod -f mongo1.conf
./mongod -f mongo2.conf
./mongod -f mongo3.conf

进入一个数据库client，设置复制集

MongoDB Enterprise > config_rs1={_id:'wukai', members:[{_id:0,host:'127.0.0.1:27017', priority:10},{_id:1, host: '127.0.0.1:27018', priority:9}, {_id:2, host:'127.0.0.1:27019', priority:9}]}
{
    "_id" : "wukai",
    "members" : [
        {
            "_id" : 0,
            "host" : "127.0.0.1:27017",
            "priority" : 10
        },
        {
            "_id" : 1,
            "host" : "127.0.0.1:27018",
            "priority" : 9
        },
        {
            "_id" : 2,
            "host" : "127.0.0.1:27019",
            "priority" : 9
        }
    ]
}

输入命令查看创建结果

MongoDB Enterprise > rs.initiate(config_rs1);
{ "ok" : 1 }
