MongoDB Replicaset 설정

몽고디비 레플리카셋 설정을 알아보겠다. 

 

1. mongodb 구조를 만든다. 

$ mkdir mongodb $ cd mongodb $ mkdir conf $ mkdir data $ mkdir log $ mkdir pid

mongodb 구조

2. conf를 설정해준다. 

2-1 mongodb_replicaset 1번 설정을 해준다

$ cd conf $ vi mongod_00.conf storage:   dbPath: /home/ubuntu/mongodb/data/rs0/   journal:     enabled: true systemLog:   destination: file   logAppend: true   path: /home/ubuntu/mongodb/log/rs0/mongod.log replication:    replSetName: "rs0"     net:   port: 27010   bindIp: 0.0.0.0 processManagement:   timeZoneInfo: /usr/share/zoneinfo

 

728x90

 

2-1 mongodb_replicaset 2번 설정을 해준다

$ vi mongod_01.conf storage:   dbPath: /home/ubuntu/mongodb/data/rs1/   journal:     enabled: true      systemLog:   destination: file   logAppend: true   path: /home/ubuntu/mongodb/log/rs1/mongod.log replication:    replSetName: "rs0"     net:   port: 27011   bindIp: 0.0.0.0 processManagement:   timeZoneInfo: /usr/share/zoneinfo

 

2-1 mongodb_replicaset 3번 설정을 해준다

$ vi mongod_01.conf storage:   dbPath: /home/ubuntu/mongodb/data/rs2/   journal:     enabled: true      systemLog:   destination: file   logAppend: true   path: /home/ubuntu/mongodb/log/rs2/mongod.log replication:    replSetName: "rs0"     net:   port: 27012   bindIp: 0.0.0.0 processManagement:   timeZoneInfo: /usr/share/zoneinfo

 

3. 생성된 파일에 권한을 부여한다. 

$ cd .. $ sudo chown -R mongodb:mongodb *

 

반응형

 

3. 서비스를 등록한다. 

cd /usr/lib/systemd/system

 

3-1 mongodb_replicaset 1번 서비스 설정

$ vi mongodb_rs0.service [Unit] Description=MongoDB Database Server Documentation=https://docs.mongodb.org/manual After=network-online.target Wants=network-online.target [Service] User=mongodb Group=mongodb EnvironmentFile=-/etc/default/mongod ExecStart=/usr/bin/mongod --config /home/ubuntu/mongodb/conf/mongod_00.conf PIDFile=/home/ubuntu/mongodb/pid/mongodb_rs0.pid # file size LimitFSIZE=infinity # cpu time LimitCPU=infinity # virtual memory size LimitAS=infinity # open files LimitNOFILE=64000 # processes/threads LimitNPROC=64000 # locked memory LimitMEMLOCK=infinity # total threads (user+kernel) TasksMax=infinity TasksAccounting=false [Install] WantedBy=multi-user.target

 

3-2 mongodb_replicaset 2번 서비스 설정

$ vi mongodb_rs1.service [Unit] Description=MongoDB Database Server Documentation=https://docs.mongodb.org/manual After=network-online.target Wants=network-online.target [Service] User=mongodb Group=mongodb EnvironmentFile=-/etc/default/mongod ExecStart=/usr/bin/mongod --config /home/ubuntu/mongodb/conf/mongod_01.conf PIDFile=/home/ubuntu/mongodb/pid/mongodb_rs1.pid # file size LimitFSIZE=infinity # cpu time LimitCPU=infinity # virtual memory size LimitAS=infinity # open files LimitNOFILE=64000 # processes/threads LimitNPROC=64000 # locked memory LimitMEMLOCK=infinity # total threads (user+kernel) TasksMax=infinity TasksAccounting=false [Install] WantedBy=multi-user.target

 

3-3 mongodb_replicaset 3번 서비스 설정

$ vi mongodb_rs2.service [Unit] Description=MongoDB Database Server Documentation=https://docs.mongodb.org/manual After=network-online.target Wants=network-online.target [Service] User=mongodb Group=mongodb EnvironmentFile=-/etc/default/mongod ExecStart=/usr/bin/mongod --config /home/ubuntu/mongodb/conf/mongod_02.conf PIDFile=/home/ubuntu/mongodb/pid/mongodb_rs2.pid # file size LimitFSIZE=infinity # cpu time LimitCPU=infinity # virtual memory size LimitAS=infinity # open files LimitNOFILE=64000 # processes/threads LimitNPROC=64000 # locked memory LimitMEMLOCK=infinity # total threads (user+kernel) TasksMax=infinity TasksAccounting=false [Install] WantedBy=multi-user.target

 

3-4 mongodb_replicaset 1,2,3번 서비스 등록

$ sudo systemctl enable mongodb_rs0.service $ sudo systemctl enable mongodb_rs1.service $ sudo systemctl enable mongodb_rs2.service

 

4. 몽고디비 시작

$ sudo systemctl start mongodb_rs0 $ sudo systemctl start mongodb_rs1 $ sudo systemctl start mongodb_rs2

 

5. 몽고디비 replicaset으로 묶어주기

$ cd ~ $ mongo --port 27010 $ rsconf = {_id: "rs0", members: [{_id: 0, host: "localhost:27010"}, {_id: 1, host: "localhost:27011"}, {_id: 2, host: "localhost:27012"}]} $ rs.initiate(rsconf)

 

이렇게 몽고디비를 설정하면, replicaset이 설정이 완료된다. 

 

그대로 따라했다면 크게 문제가 없을 것이다.

 

그럼 샤드 설정에 대해 알아보겠다.
