CentOS 7에 대한 고정 IP를 얻지 못함

고정 IP에 무엇이 빠졌는지 잘 모르겠습니다.

이것은 내 네트워크 구성 파일입니다.

/etc/hosts:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.2 puppet master
192.168.1.3 agent1 machine1
192.168.1.4 agent2 machine2
192.168.1.5 agent3 machine3

/etc/sysconfig/network:

# Created by anaconda
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=agent1
GATEWAY=192.168.1.1

기본 인터페이스 구성 파일 /etc/sysconfig/network-scripts/ifcfg-enp0s3:

TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
NAME=eth0

PREFIX=32
GATEWAY=192.168.1.1
DNS1=192.168.1.1
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes

출력은 다음과 같습니다 ip addr.
