修改mongodb(带仲裁节点的副本集)各机器端口

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,

                        "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
                },
                {

                        "buildIndexes" : true,
                        "hidden" : false,
                        "priority" : 1,
                        "tags" : {

                        },
                        "slaveDelay" : 0,
                        "votes" : 1
                }
        ],

                        "w" : 1,
                        "wtimeout" : 0
