finalshell连不上VM创建的centos7，centos7也 ping不通网关问题检查

1、centos7 ping不通,用 ip addr show命令检查

ip addr show

[root@localhost atguigu]# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:0c:29:fe:91:ba brd ff:ff:ff:ff:ff:ff
    inet 192.168.30.101/24 brd 192.168.30.255 scope global noprefixroute ens33
       valid_lft forever preferred_lft forever
    inet6 2409:8a50:4b8:b470:929c:6ef0:f3e3:d61d/64 scope global noprefixroute dynamic 
       valid_lft 259188sec preferred_lft 172788sec
    inet6 fe80::ffb0:89d2:9f7b:8a5b/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
    link/ether 52:54:00:31:0f:5c brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
       valid_lft forever preferred_lft forever

2、开启 ens33网卡

ip link set dev ens33 up

还是拼不通

3、检查ens33配置文件

nano /etc/sysconfig/network-scripts/ifcfg-enp0s3

TYPE="Ethernet"               # 接口类型为以太网，正确。
PROXY_METHOD="none"           # 不使用代理，正确（若无代理需求）。
BROWSER_ONLY="no"             # 非仅浏览器代理，正确。
