配置MongoDB的yum源

tee /etc/yum.repos.d/mongodb-org-3.4.repo <<-'EOF'
[mongodb-org-3.4]  
name=MongoDB Repository  
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/  
gpgcheck=0  
enabled=1  
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc
#这里可以修改 gpgcheck=0, 省去gpg验证
EOF

刷新缓存

[root@localhost ~]# yum makecache

安装

yum -y install mongodb-org

查找配置文件

whereis mongod

注释掉mongod.conf中的bindIp

#  bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.

启动mongodb ：

systemctl start mongod.service

加入开机启动

systemctl enable mongod.service

防火墙开端口

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

进入数据库添加用户

mongo;

use admin;

db.createUser(
  {
    user: "admin",
    pwd: "123456",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]</code>
  }
);

修改配置文件,启用身份认证

#打开注释
security:
#加入这句
  authorization: enabled

重启mongo

systemctl restart mongod

以上
