1. 创建文件

vim /etc/yum.repos.d/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

2. 安装

yum install -y mongodb-org

默认数据位置

/var/lib/mongo

默认日志位置

/var/log/mongodb

配置文件位置

vim /etc/mongod.conf

修改监听ip和端口

net:
  port: 3717
  bindIp: 0.0.0.0

3. 开放3717端口

3.1 SElinux

semanage port -a -t mongod_port_t -p tcp 3717

3.2 防火墙

firewall-cmd --zone=public --add-port=3717/tcp --permanent
firewall-cmd --reload

4. 开启服务 mongod

systemctl start mongod # 开启
systemctl stop mongod # 关闭
systemctl enable mongod # 开机启动

若启动失败

● mongod.service - MongoDB Database Server
   Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since 二 2021-08-17 15:13:45 CST; 10s ago

8月 17 15:13:45 zngw systemd[1]: mongod.service failed.

很大的可能是权限问题，因为在/usr/lib/systemd/system/mongod.service默认配置中，我们看到是以mongod用户组和用户来启动的。mongod对数据文件和日志文件没有访问权限。添加一下再重试就可以了

chown -Rc mongod. /var/log/mongodb
chown -Rc mongod. /var/lib/mongo

5. 启动客户端 mongo

mongo --host 127.0.0.1:3717

创建root用户

mongo --host 127.0.0.1:3717 admin --eval "db.createUser({ user: 'root', pwd: '123456', roles: [ { role: 'root', db: 'admin' } , 'readWriteAnyDatabase'] })"

6. 卸载

6.1 删除安装包

sudo yum erase $(rpm -qa | grep mongodb-org)

6.2 删除数据文件

rm -r /var/log/mongodb
rm -r /var/lib/mongo
