1.  创建挂载目录

mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27018/data/db
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27018/log
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27018/conf
     touch  /usr/local/src/mongodb/replica_sets/myrs_27018/log/mongod.log
     
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27019/data/db
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27019/log
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27019/conf
     touch  /usr/local/src/mongodb/replica_sets/myrs_27019/log/mongod.log
    
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27020/data/db
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27020/log
     mkdir -p /usr/local/src/mongodb/replica_sets/myrs_27020/conf
     touch  /usr/local/src/mongodb/replica_sets/myrs_27020/log/mongod.log
    
    chmod -R 777 /usr/local/src/mongodb/replica_sets

2.创建配置文件mongod.conf

1.
    storage:
        dbPath: "/data/db"
        journal:
            enabled: true
    systemLog:
        destination: file
        path: "/data/log/mongod.log"
        logAppend: true
    net:
        bindIp: localhost,0.0.0.0
        port: 27018
    replication: 
    	replSetName: myrs
    
    2.
    storage:
        dbPath: "/data/db"
        journal:
            enabled: true
    systemLog:
        destination: file
        path: "/data/log/mongod.log"
        logAppend: true
    net:
        bindIp: localhost,0.0.0.0
        port: 27019
    replication: 
    	replSetName: myrs
    
    3.
    storage:
        dbPath: "/data/db"
        journal:
            enabled: true
    systemLog:
        destination: file
        path: "/data/log/mongod.log"
        logAppend: true
    net:
        bindIp: localhost,0.0.0.0
        port: 27020
    replication: 
    	replSetName: myrs

3.创建容器

docker run -itd --name mongodb_rs27018  --restart=always --privileged -p 27018:27018  \
    -v /usr/local/src/mongodb/replica_sets/myrs_27018/data/db:/data/db \
    -v /usr/local/src/mongodb/replica_sets/myrs_27018/conf:/data/configdb \
    -v /usr/local/src/mongodb/replica_sets/myrs_27018/log:/data/log/ \
    mongo:4.2.8  --config /data/configdb/mongod.conf
    
    docker run -itd --name mongodb_rs27019  --restart=always --privileged -p 27019:27019  \
    -v /usr/local/src/mongodb/replica_sets/myrs_27019/data/db:/data/db \
    -v /usr/local/src/mongodb/replica_sets/myrs_27019/conf:/data/configdb \
    -v /usr/local/src/mongodb/replica_sets/myrs_27019/log:/data/log/ \
    mongo:4.2.8  --config /data/configdb/mongod.conf
    
    docker run -itd --name mongodb_rs27020  --restart=always --privileged -p 27020:27020  \
    -v /usr/local/src/mongodb/replica_sets/myrs_27020/data/db:/data/db \
    -v /usr/local/src/mongodb/replica_sets/myrs_27020/conf:/data/configdb \
    -v /usr/local/src/mongodb/replica_sets/myrs_27020/log:/data/log/ \
    mongo:4.2.8  --config /data/configdb/mongod.conf

4.初始化配置副本集和主节点  
使用客户端命令连接任意一个节点，但这里尽量要连接主节点(27018节点)：

[root@promote log]#docker exec -it d46982e5c9ea /bin/bash
    root@d46982e5c9ea:/# mongo --port=27018
    var config={  
         _id:"myrs", 
         members:[ 
             { _id:0,host:"192.168.204.131:27018"},  
             { _id:1,host:"192.168.204.131:27019"}, 
             { _id:2,host:"192.168.204.131:27020",arbiterOnly: true,}
    ]}
    rs.initiate(config)
    myrs:OTHER> 
    myrs:PRIMARY>

7.查看副本集状态

myrs:PRIMARY> rs.status()
    { 
    ...
    	"members" : [
    					{ 
    							"_id" : 0,
    							"name" : "d46982e5c9ea:27018",
    							"health" : 1,
    							"state" : 1,
    							"stateStr" : "PRIMARY",
    							"uptime" : 658,
    							"optime" : { 
    									"ts" : Timestamp(1593675531, 1),
    									"t" : NumberLong(1)
    							},
    							"optimeDate" : ISODate("2020-07-02T07:38:51Z"),
    							"syncingTo" : "",
    							"syncSourceHost" : "",
    							"syncSourceId" : -1,
    							"infoMessage" : "",
    							"electionTime" : Timestamp(1593675201, 2),
    							"electionDate" : ISODate("2020-07-02T07:33:21Z"),
    							"configVersion" : 3,
    							"self" : true,
    							"lastHeartbeatMessage" : ""
    					},
    					{ 
    							"_id" : 1,
    							"name" : "192.168.204.131:27019",
    							"health" : 1,
    							"state" : 0,
    							"stateStr" : "STARTUP",
    							"uptime" : 116,
    							"optime" : { 
    									"ts" : Timestamp(0, 0),
    									"t" : NumberLong(-1)
    							},
    							"optimeDurable" : { 
    									"ts" : Timestamp(0, 0),
    									"t" : NumberLong(-1)
    							},
    							"optimeDate" : ISODate("1970-01-01T00:00:00Z"),
    							"optimeDurableDate" : ISODate("1970-01-01T00:00:00Z"),
    							"lastHeartbeat" : ISODate("2020-07-02T07:38:54.670Z"),
    							"lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"),
    							"pingMs" : NumberLong(0),
    							"lastHeartbeatMessage" : "",
    							"syncingTo" : "",
    							"syncSourceHost" : "",
    							"syncSourceId" : -1,
    							"infoMessage" : "",
    							"configVersion" : -2
    					},
    					{ 
    							"_id" : 2,
    							"name" : "192.168.204.131:27020",
    							"health" : 1,
    							"state" : 0,
    							"stateStr" : "STARTUP",
    							"uptime" : 42,
    							"lastHeartbeat" : ISODate("2020-07-02T07:38:54.669Z"),
    							"lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"),
    							"pingMs" : NumberLong(0),
    							"lastHeartbeatMessage" : "",
    							"syncingTo" : "",
    							"syncSourceHost" : "",
    							"syncSourceId" : -1,
    							"infoMessage" : "",
    							"configVersion" : -2
    					}
    			]
    	...
    }

8.主节点上新增一个测试db

myrs:PRIMARY> use articledb
    switched to db articledb
    myrs:PRIMARY> db
    articledb
    myrs:PRIMARY> db.comment.insert({ "articleid":"100000","content":"今天天气真好，阳光 明媚","userid":"1001","nickname":"Rose","createdatetime":new Date()})
    WriteResult({  "nInserted" : 1 })
    myrs:PRIMARY> db.comment.find()
    {  "_id" : ObjectId("5efd931aea01b557f213c082"), "articleid" : "100000", "content" : "今天天气真好，阳光 明媚", "userid" : "1001", "nickname" : "Rose", "createdatetime" : ISODate("2020-07-02T07:56:10.778Z") }

9.副本节点接受slave

> rs.slaveOk()

10.仲裁从节点接受slave

> rs.slaveOk()
