mongdb副本集部署

兩臺機器

1.在/etc/hosts文件中寫上
192.168.255.133 worker1
192.168.255.134 worker2

2.修改配置文件/etc/mongdb.conf
bindIp: 0.0.0.0 #供全部機器訪問
replication:
replSetName: rs # 給副本集取名字叫rs

3.啓動
mongod

4.初始化副本集

mongo

rs.initiate()

5.添加成員節點
rs.add("worker2:27017")

rs.addArb("182.48.115.239:27017") #添加仲裁節點

6.進入mongodb shell中查看配置

mongo

rs.conf()
MongoDB Enterprise rs:PRIMARY> rs.conf()
