创建repo

vim /etc/yum.repos.d/mongodb-org-5.0.repo，填入以下内容：

[mongodb-org-5.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/5.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-5.0.asc

安装

sudo yum install -y mongodb-org

启动 mongodb

systemctl start mongod
systemctl enable mongod
systemctl status mongod

如果有unit的报错

Unit systemctl.service not found 运行这个代码：

systemctl daemon-reload # 重新加载某个服务的配置文件

如果新安装了一个服务，归属于 systemctl 管理，想让新服务的服务程序配置文件生效，需重新加载

如果开启了防火墙

firewall-cmd --zone=public --add-port=27017/tcp --permanent
firewall-cmd --reload
