2.安装并修改配置

yum  install -y vim  mongodb
vim /etc/mongod.conf

bindIp: 172.0.0.1 改为 bindIp: 0.0.0.0 #注意冒号与ip之间需要一个空格

3.启动，停止，查看状态，重启

systemctl start mongod.service
systemctl stop mongod.service
systemctl status mongod.service
systemctl restart mongod.service

4.关闭firewall：

systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动

5.设置开机启动
