一、Master-Slave 方式
1、主节点信息【主节点】
2、主节点配置【主节点】
bind_ip=192.168.206.158 port=27017 fork=true dbpath=/usr/local/mongodb/node01/data/db logpath=/usr/local/mongodb/node01/logs/mongodb.log logappend=true # master config master=true source=192.168.206.159:270173、从节点信息【从节点】
4、从节点增加配置【从节点】
bind_ip=192.168.206.159 port=27017 fork=true dbpath=/usr/local/mongodb/node01/data/db logpath=/usr/local/mongodb/node01/logs/mongodb.log logappend=true #slave config slave=true source=192.168.206.158:27017
5、启动主节点服务【主节点】
命令：mongod --config mongodb.conf
6、启动从节点服务【从节点】
命令：mongod --config mongodb.conf
7、连接主节点客户端【主节点】
命令：mongo --host 192.168.206.158 --port 27017
8、查看当前节点是否是主节点及相关信息【主节点】
命令：rs.isMaster()
9、连接从节点客户端【从节点】
命令：mongo --host 192.168.206.159 --port 27017
10、查看当前节点是否是主节点及其相关信息【从节点】
命令：rs.isMaster()
11、从节点备份数据的来源【从节点】
命令：rs.printSlaveReplicationInfo()
12、从节点默认不可读写，需要执行命令允许【从节点】
命令：rs.slaveOk()
13、查看系统数据库，查看主节点信息【从节点】
14、主节点插入数据测试
15、从节点上查看备份情况
结果：成功
二、副本集【仲裁模式】
1、节点配置目录
|----根目录：mongodb
|------------主节点：node01
|--------------------数据目录：data
|----------------------------数据库目录：db
|--------------------日志目录：logs
|------------从节点：node02
|--------------------数据目录：data
|----------------------------数据库目录：db
|--------------------日志目录：logs
|------------仲裁节点：node03
|--------------------数据目录：data
|----------------------------数据库目录：db
|--------------------日志目录：logs
2、副本集工作原理
2.1、主节点的所有数据操作都会存在一个系统表中，即 local 数据库的 oplog.rs 集合中
2.2、从节点异步的定期轮询主节点上的 oplog.rs 集合，然后对自己的数据副本执行更新操作
2.3、第一次同步时采用全量，而后依次采用增将的方式，执行增量数据的命令达到同步的作用
3、配置文件
3.1、node01节点配置
# 访问地址 bind_ip=192.168.206.158 # 默认27017 port=27001 # 是否以守护进程方式运行 fork=true # 日志文件位置 logpath=/usr/local/mongodb/node01/logs/mongodb.log # 以追加方式写入日志 logappend=true # 数据库文件位置 dbpath=/usr/local/mongodb/node01/data/db # 副本集名称：名称相同的副本集表示在同一个副本中 replSet=yfset13.2、node02节点配置
# 访问地址 bind_ip=192.168.206.158 # 默认27017 port=27002 # 是否以守护进程方式运行 fork=true # 日志文件位置 logpath=/usr/local/mongodb/node02/logs/mongodb.log # 以追加方式写入日志 logappend=true # 数据库文件位置 dbpath=/usr/local/mongodb/node02/data/db # 副本集名称：名称相同的副本集表示在同一个副本中 replSet=yfset13.3、node03节点配置
# 访问地址 bind_ip=192.168.206.158 # 默认27017 port=27003 # 是否以守护进程方式运行 fork=true # 日志文件位置 logpath=/usr/local/mongodb/node03/logs/mongodb.log # 以追加方式写入日志 logappend=true # 数据库文件位置 dbpath=/usr/local/mongodb/node03/data/db # 副本集名称：名称相同的副本集表示在同一个副本中 replSet=yfset14、启动服务
4.1、启动 node01 服务
命令：mongod --config node01/mongodb.conf
4.2、启动 node02 服务
命令：mongod --config node02/mongodb.conf
4.3、启动 node03 服务
命令：mongod --config node03/mongodb.conf
5、连接任意客户端
命令：mongo --host 192.168.206.158 --port 27002
6、初始化副本操作
命令：rs.initiate({"_id":"yfset1",members:[{"_id":1,host:"192.168.206.158:27001",priority:3},{"_id":2,host:"192.168.206.158:27002",priority:4},{"_id":3,host:"192.168.206.158:27003",arbiterOnly:true}]})

7、查看整个副本状态
命令：rs.status()
{ "set": "yfset1", "date": ISODate("2017-03-09T22:38:51.807Z"), "myState": 1, "term": NumberLong(1), "heartbeatIntervalMillis": NumberLong(2000), "optimes": { "lastCommittedOpTime": { "ts": Timestamp(1489099122, 1), "t": NumberLong(1) }, "appliedOpTime": { "ts": Timestamp(1489099122, 1), "t": NumberLong(1) }, "durableOpTime": { "ts": Timestamp(1489099122, 1), "t": NumberLong(1) } }, "members": [ { "_id": 1, "name": "192.168.206.158:27001", "health": 1, "state": 2, "stateStr": "SECONDARY", "uptime": 70, "optime": { "ts": Timestamp(1489099122, 1), "t": NumberLong(1) }, "optimeDurable": { "ts": Timestamp(1489099122, 1), "t": NumberLong(1) }, "optimeDate": ISODate("2017-03-09T22:38:42Z"), "optimeDurableDate": ISODate("2017-03-09T22:38:42Z"), "lastHeartbeat": ISODate("2017-03-09T22:38:50.164Z"), "lastHeartbeatRecv": ISODate("2017-03-09T22:38:49.924Z"), "pingMs": NumberLong(0), "syncingTo": "192.168.206.158:27002", "configVersion": 1 }, { "_id": 2, "name": "192.168.206.158:27002", "health": 1, "state": 1, "stateStr": "PRIMARY", "uptime": 122, "optime": { "ts": Timestamp(1489099122, 1), "t": NumberLong(1) }, "optimeDate": ISODate("2017-03-09T22:38:42Z"), "infoMessage": "could not find member to sync from", "electionTime": Timestamp(1489099072, 1), "electionDate": ISODate("2017-03-09T22:37:52Z"), "configVersion": 1, "self": true }, { "_id": 3, "name": "192.168.206.158:27003", "health": 1, "state": 7, "stateStr": "ARBITER", "uptime": 70, "lastHeartbeat": ISODate("2017-03-09T22:38:50.164Z"), "lastHeartbeatRecv": ISODate("2017-03-09T22:38:47.840Z"), "pingMs": NumberLong(0), "configVersion": 1 } ], "ok": 1 }
8、主节点插入数据
