需求:因为端口调整，需要改变副本的备份集
1.查看当前的副本集信息
[root@localhost bin]# ./mongo 192.168.1.134:10001 repltest:PRIMARY> use admin repltest:PRIMARY> db.auth("sa","123456") repltest:PRIMARY> rs.config() { "_id" : "repltest", "version" : 1, "members" : [ { "_id" : 0, "host" : "192.168.1.134:10001", "arbiterOnly" : false, "buildindexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : 0, "Votes" : 1 }, { "_id" : 1, "host" : "192.168.1.135:10002", "arbiterOnly" : false, "buildindexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : 0, "Votes" : 1 }, { "_id" : 2, "host" : "192.168.1.135:10003", "arbiterOnly" : true, "buildindexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : 0, "Votes" : 1 } ], "settings" : { "chainingallowed" : true, "heartbeatTimeoutSecs" : 10, "getLastErrorModes" : { }, "getLastErrorDefaults" : { "w" : 1, "wtimeout" : 0 } } }
我们需要将这里各机器的端口10001,10002,10003分别修改为20001,20002,20003
2.修改从库192.168.1.135:10002为192.168.1.135:20002
2.1 停掉该从库
[root@localhost bin]# ./mongo localhost:10002
repltest:SECONDARY> use admin
repltest:SECONDARY> db.auth("sa","123456")
repltest:SECONDARY> db.shutdownServer()
2.2修改配置文件(mongo.cnf)将端口10002修改为20002
port = 20002
2.3启动该重库
[root@localhost bin]# ./mongod -f /opt/mongodb3015_slave/conf/mongo.cnf
2.4登陆主库执行如下命令
repltest:PRIMARY> rs.remove("192.168.1.135:10002") ##移除原配置文件中的已经变更地址的主机
repltest:PRIMARY> rs.add("192.168.1.135:20002") ##添加变更后的端口
2.5查看配置是否生效
rs.config()
rs.status()
3.修改仲裁节点的端口
3.1停掉仲裁节点
[root@localhost bin]# ./mongo localhost:10003
MongoDB shell version: 3.0.15
connecting to: localhost:10003/test
repltest:ARBITER> use admin
switched to db admin
repltest:ARBITER> db.auth("sa","123456")
Error: 18 Authentication Failed.
0
repltest:ARBITER> db.shutdownServer()
3.2修改配置文件(mongo.cnf)将端口10003修改为20003
port = 20002
3.3启动该重库
[root@localhost bin]# ./mongod -f /opt/mongodb3015_arbiter/conf/mongo.cnf
3.4登陆主库执行如下命令
repltest:PRIMARY> rs.remove("192.168.1.135:10003") ##移除原配置文件中的已经变更地址的主机
repltest:PRIMARY> rs.addArb("192.168.1.135:20003") ##添加仲裁节点
3.5查看配置是否生效
rs.config()
rs.status()
4.修改主库192.168.1.134:10001为192.168.1.134:10002
4.1 停掉该主库
[root@localhost bin]# ./mongo localhost:10001
repltest:PRIMARY> use admin
repltest:PRIMARY> db.auth("sa","123456")
repltest:PRIMARY> db.shutdownServer()
这个时候该另外一个从库会变更为主库
4.2修改配置文件(mongo.cnf)将端口10001修改为20001
port = 20001
4.3启动该库
[root@localhost bin]# ./mongod -f /opt/mongodb3015/conf/mongo.cnf
4.4登陆主库执行如下命令
root@localhost bin]# ./mongo 192.168.1.135:20002
repltest:PRIMARY> use admin
repltest:PRIMARY> db.auth("sa","123456")
repltest:PRIMARY> rs.remove("192.168.1.134:10001") ##移除原配置文件中的已经变更地址的主机
repltest:PRIMARY> rs.add("192.168.1.134:20001") ##添加变更后的端口
5.整个配置完成后查看配置和状态
repltest:PRIMARY> rs.conf() { "_id" : "repltest", "version" : 7, "members" : [ { "_id" : 3, "host" : "192.168.1.135:20002", "arbiterOnly" : false, "buildindexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : 0, "Votes" : 1 }, { "_id" : 4, "host" : "192.168.1.135:20003", "arbiterOnly" : true, "buildindexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : 0, "Votes" : 1 }, { "_id" : 5, "host" : "192.168.1.134:20001", "arbiterOnly" : false, "buildindexes" : true, "hidden" : false, "priority" : 1, "tags" : { }, "slaveDelay" : 0, "Votes" : 1 } ], "settings" : { "chainingallowed" : true, "heartbeatTimeoutSecs" : 10, "getLastErrorModes" : { }, "getLastErrorDefaults" : { "w" : 1, "wtimeout" : 0 } } } repltest:PRIMARY> rs.status() { "set" : "repltest", "date" : ISODate("2019-02-21T01:13:14.107Z"), "myState" : 1, "members" : [ { "_id" : 3, "name" : "192.168.1.135:20002", "health" : 1, "state" : 1, "stateStr" : "PRIMARY", "uptime" : 1504, "optime" : Timestamp(1550711569, 1), "optimeDate" : ISODate("2019-02-21T01:12:49Z"), "electionTime" : Timestamp(1550711217, 1), "electionDate" : ISODate("2019-02-21T01:06:57Z"), "configVersion" : 7, "self" : true }, { "_id" : 4, "name" : "192.168.1.135:20003", "health" : 1, "state" : 7, "stateStr" : "ARBITER", "uptime" : 596, "lastHeartbeat" : ISODate("2019-02-21T01:13:13.747Z"), "lastHeartbeatRecv" : ISODate("2019-02-21T01:13:12.451Z"), "pingMs" : 0, "configVersion" : 7 }, { "_id" : 5, "name" : "192.168.1.134:20001", "health" : 1, "state" : 2, "stateStr" : "SECONDARY", "uptime" : 22, "optime" : Timestamp(1550711569, 1), "optimeDate" : ISODate("2019-02-21T01:12:49Z"), "lastHeartbeat" : ISODate("2019-02-21T01:13:13.791Z"), "lastHeartbeatRecv" : ISODate("2019-02-21T01:13:13.851Z"), "pingMs" : 0, "syncingTo" : "192.168.1.135:20002", "configVersion" : 7 } ], "ok" : 1 }
