一. 添加Repo源

创建/etc/yum.repos.d/mongodb-org-3.4.repo

添加如下内容

[mongodb-org-3.4]

name=MongoDB Repository

baseurl=https://repo.mongodb.org/yum/amazon/2013.03/mongodb-org/3.4/x86_64/

gpgcheck=1

enabled=1

gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc

二.安装

sudo yum install -y mongodb-org

1. 修改/etc/mongod.conf配置

修改端口，bindIp，添加replication配置

net:

port: 10336

bindIp: 127.0.0.1,192.168.177.141

Listen to local interface only, comment to listen on all interfaces.

replication:

oplogSizeMB: 2048

replSetName: mcluster

2.在各个节点启动mongod服务

/etc/init.d/mongod start

3.在第一个节点进入mongo shell

mongo

输入以下内容

rs.initiate()

rs.conf()

rs.add(“192.168.177.142:10336”)

rs.add(“192.168.177.143:10336”)

结果如下

{“ok” : 1}

表示成功

rs.conf()

可以查看集群的状态

rs.status()

三.创建管理员账户

mongo

use admin

db.createUser({ user: “shao”, pwd: “shaodong”, roles: [ { role: “root”, db: “admin” } ] })

四.生产keyfile

推出mongo shell

mkdir -p /usr/local/mongodb/conf

openssl rand -base64 741 > /usr/local/mongodb/conf/mongodb-keyfile

将keyfile拷贝至相应位置，同时也必须拷贝至所有节点

chmod 600 /usr/local/mongodb/conf/mongodb-keyfile

chown -R mongod.mongod /usr/local/mongodb/conf/mongodb-keyfile

五.修改配置文件,在/etc/mongod.conf中添加，所有节点

security:

authorization: enabled

keyFile: /usr/local/mongodb/conf/mongodb-keyfile

六.重启mongod

/etc/init.d/mongo restart
