1.基本資料如下伺服器位址 192.168.73.129複本集名稱 rs容器節點及連接埠映射        m0 37017:27017        m1 47017:27017        m2 57017:27017註：機器環境安裝docker2.部署步驟2.1下載mongo鏡像

docker pull mongo

2.2 啟動三個節點

docker run --name m0 -p 37017:27017 -d mongo --replSet "rs"docker run --name m1 -p 47017:27017 -d mongo --replSet "rs"docker run --name m2 -p 57017:27017 -d mongo --replSet "rs"

docker ps -a   //查看啟動的容器

2.3 串連任意一個節點，進行複本集配置

進入其中一個容器：docker exec -it de242cc5fa5a  /bin/bash 

串連三個節點中的任意一個,注意ip地址為宿主機ip,我當前的為192.168.73.129

mongo --host 192.168.73.129 --port 37017

此時已串連到m0節點，進行複本集配置

var config={ _id:"rs", members:[ {_id:0,host:"192.168.73.129:37017"}, {_id:1,host:"192.168.73.129:47017"}, {_id:2,host:"192.168.73.129:57017"}]}；rs.initiate(config)

響應應該類似下面，注意此時命令提示字元已經發生變化，由原來的 > 變成了 rs:SECONDARY>

{ "ok" : 1, "operationTime" : Timestamp(1522810920, 1), "$clusterTime" : { "clusterTime" : Timestamp(1522810920, 1), "signature" : { "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="), "keyId" : NumberLong(0) } }}

2.4查看複本集配置資訊

rs:SECONDARY> rs.conf(){ "_id" : "rs", "version" : 1, "protocolVersion" : NumberLong(1), "writeConcernMajorityJournalDefault" : true, "members" : [ { "_id" : 0, "host" : "192.168.73.129:37017", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 1, "host" : "192.168.73.129:47017", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 }, { "_id" : 2, "host" : "192.168.73.129:57017", "arbiterOnly" : false, "buildIndexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : NumberLong(0), "votes" : 1 } ], "settings" : { "chainingAllowed" : true, "heartbeatIntervalMillis" : 2000, "heartbeatTimeoutSecs" : 10, "electionTimeoutMillis" : 10000, "catchUpTimeoutMillis" : -1, "catchUpTakeoverDelayMillis" : 30000, "getLastErrorModes" : { }, "getLastErrorDefaults" : { "w" : 1, "wtimeout" : 0 }, "replicaSetId" : ObjectId("5b3c937896d237ac24a0648e") }}rs:SECONDARY>

2.5 查看複本集狀態

rs:SECONDARY> rs.status(){ "set" : "rs", "date" : ISODate("2018-07-04T09:45:38.110Z"), "myState" : 2, "term" : NumberLong(1), "syncingTo" : "192.168.73.129:37017", "syncSourceHost" : "192.168.73.129:37017", "syncSourceId" : 0, "heartbeatIntervalMillis" : NumberLong(2000), "optimes" : { "lastCommittedOpTime" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "readConcernMajorityOpTime" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "appliedOpTime" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "durableOpTime" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) } }, "lastStableCheckpointTimestamp" : Timestamp(1530697480, 1), "members" : [ { "_id" : 0, "name" : "192.168.73.129:37017", "health" : 1, "state" : 1, "stateStr" : "PRIMARY", "uptime" : 967, "optime" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "optimeDurable" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "optimeDate" : ISODate("2018-07-04T09:45:30Z"), "optimeDurableDate" : ISODate("2018-07-04T09:45:30Z"), "lastHeartbeat" : ISODate("2018-07-04T09:45:36.221Z"), "lastHeartbeatRecv" : ISODate("2018-07-04T09:45:36.296Z"), "pingMs" : NumberLong(0), "lastHeartbeatMessage" : "", "syncingTo" : "", "syncSourceHost" : "", "syncSourceId" : -1, "infoMessage" : "", "electionTime" : Timestamp(1530696579, 1), "electionDate" : ISODate("2018-07-04T09:29:39Z"), "configVersion" : 1 }, { "_id" : 1, "name" : "192.168.73.129:47017", "health" : 1, "state" : 2, "stateStr" : "SECONDARY", "uptime" : 967, "optime" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "optimeDurable" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "optimeDate" : ISODate("2018-07-04T09:45:30Z"), "optimeDurableDate" : ISODate("2018-07-04T09:45:30Z"), "lastHeartbeat" : ISODate("2018-07-04T09:45:36.221Z"), "lastHeartbeatRecv" : ISODate("2018-07-04T09:45:36.219Z"), "pingMs" : NumberLong(0), "lastHeartbeatMessage" : "", "syncingTo" : "192.168.73.129:37017", "syncSourceHost" : "192.168.73.129:37017", "syncSourceId" : 0, "infoMessage" : "", "configVersion" : 1 }, { "_id" : 2, "name" : "192.168.73.129:57017", "health" : 1, "state" : 2, "stateStr" : "SECONDARY", "uptime" : 2153, "optime" : { "ts" : Timestamp(1530697530, 1), "t" : NumberLong(1) }, "optimeDate" : ISODate("2018-07-04T09:45:30Z"), "syncingTo" : "192.168.73.129:37017", "syncSourceHost" : "192.168.73.129:37017", "syncSourceId" : 0, "infoMessage" : "", "configVersion" : 1, "self" : true, "lastHeartbeatMessage" : "" } ], "ok" : 1, "operationTime" : Timestamp(1530697530, 1), "$clusterTime" : { "clusterTime" : Timestamp(1530697530, 1), "signature" : { "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="), "keyId" : NumberLong(0) } }}rs:SECONDARY>
