Linux：yum安装mongoDB-4.4.2

yum安装mongoDB-4.4.2

安装mongodb的方法有很多，今天主要分享的是配置yum源，直接使用yum安装的方法。过程是参考官方的教程。

创建yum源

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# vim mongodb-org-4.4.repo
[mongodb-org-4.4]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc

yum安装

[root@localhost yum.repos.d]# yum install -y mongodb-org

启动服务

[root@localhost ~]# systemctl start mongod
如果报 Failed to start mogond.service: Unit not found. 
那么就执行：
[root@localhost ~]# systemctl daemon-reload
#检查端口
[root@localhost ~]# netstat -ntlp
Active Internet connections (only servers)

进入mongodb

[root@localhost ~]# mongo
MongoDB shell version v4.4.2
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session {
    
     "id" : UUID("488c70a0-9b56-429e-a6ee-72968b845b2c") }
MongoDB server version: 4.4.2
---
The server generated these startup warnings when booting:
        2020-12-07T10:21:55.297+08:00: Access control is not enabled for the database. Read and write access to data and configuration is unrestricted
        2020-12-07T10:21:55.298+08:00: /sys/kernel/mm/transparent_hugepage/enabled is 'always'. We suggest setting it to 'never'
        2020-12-07T10:21:55.298+08:00: /sys/kernel/mm/transparent_hugepage/defrag is 'always'. We suggest setting it to 'never'

---
        Enable MongoDB's free cloud-based monitoring service, which will then receive and display
        metrics about your deployment (disk utilization, CPU, operation statistics, etc).

        The monitoring data will be available on a MongoDB website with a unique URL accessible to you
        and anyone you share the URL with. MongoDB may use this information to make product
        improvements and to suggest MongoDB products and deployment options to you.

        To enable free monitoring, run the following command: db.enableFreeMonitoring()
        To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
