mongdb副本集部署

两台机器

1.在/etc/hosts文件中写上
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 #供所有机器访问
replication:
replSetName: rs # 给副本集取名字叫rs

3.启动
mongod

4.初始化副本集

rs.initiate()

5.添加成员节点

rs.add("worker2:27017")

rs.addArb("182.48.115.239:27017") #添加仲裁节点

6.进入mongodb shell中查看配置

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