一、环境介绍

1.配置模式：一主两从
2.系统：rhel7.1
3.配置节点及IP： node-3 192.168.3.13 
                                node-4 192.168.3.14
                                node-5 192.168.3.15

二、配置mongodb的yum源

# /etc/yum.repos.d/mongodb.repo
[mongodb-org]
name=MongoDB Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/mongodb/yum/el$releasever/
gpgcheck=0
enabled=1

三、安装mongodb

yum install -y mongodb-org-server mongodb-org

三、启动mongodb

1.mongodb启动

[root@node-3 yum.repos.d]# systemctl start mongod.service 

2.查看mongodb的状态

[root@node-3 yum.repos.d]# systemctl status mongod
● mongod.service - MongoDB Database Server
   Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)
   Active: active (running) since Wed 2022-01-19 17:58:27 CST; 11s ago
     Docs: https://docs.mongodb.org/manual
  Process: 15741 ExecStart=/usr/bin/mongod $OPTIONS (code=exited, status=0/SUCCESS)
  Process: 15740 ExecStartPre=/usr/bin/chmod 0755 /var/run/mongodb (code=exited, status=0/SUCCESS)
  Process: 15734 ExecStartPre=/usr/bin/chown mongod:mongod /var/run/mongodb (code=exited, status=0/SUCCESS)
  Process: 15731 ExecStartPre=/usr/bin/mkdir -p /var/run/mongodb (code=exited, status=0/SUCCESS)
 Main PID: 15750 (mongod)
   CGroup: /system.slice/mongod.service
           └─15750 /usr/bin/mongod -f /etc/mongod.conf

Jan 19 17:58:27 node-3 systemd[1]: Starting MongoDB Database Server...

3.查看监听端口

[root@node-3 ~]# netstat -tunlp |grep 27017
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      15750/mongod        
[root@node-3 ~]# 

四、进入mongodb

[root@node-3 ~]# mongo
MongoDB shell version v5.0.5

五、查看mongodb的所有数据库

> show dbs;
admin   0.000GB    #超级管理员的库，存储用户信息
config  0.000GB  #存储集群配置
local   0.000GB
> show databases;
admin   0.000GB
config  0.000GB
local   0.000GB
>
