mongodb Version 5访问控制与两个读副本

Question

我有三个ubuntu 20.04服务器:

1. db-master
2. db-node1
3. db-node2

我想知道如何启用访问控制。服务器工作正常，除非将以下配置添加到/etc/mongod.conf提前感谢:

$ mongo --version
MongoDB shell version v5.0.1
$ sudo vim /etc/mongod.conf 
security:
keyFile: "/home/ubuntu/security.keyFile"
authorization: enabled
$ sudo systemctl status mongod
● mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
Active: active (running)
$ sudo systemctl restart mongod
ubuntu@db-node2:~$ sudo systemctl status mongod
● mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
Active: failed

# mongod.conf
