note:

configure host network (static)
cd /etc/sysconfig/network-scripts/
change:

BOOTPROTO=dhcp

To:

BOOTPROTO=static
At the bottom of that file, add the following:
IPADDR=192.168.1.200
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=1.0.0.1
DNS2=1.1.1.1
DNS3=8.8.4.4

nmcli con ## 查看网卡的UUID信息

install mongodb

when grant for database, you should grant for 'controler' ('localhost', '%')

and
flush privileges;

you should stop the controller host firewall
systemctl stop firewalld.service
