Yum command error reporting solution

Problem Description:

An error occurs when running the yum install gcc-c + + command on the VMware virtual machine

Error message:

6 - "Counldn't resolve host 'mirrorlist.centos.org'"

Possible cause analysis:

1. DNS is not set

2. The connection mode of the network adapter is incorrect. The NAT mode is used locally and the bridge mode is used for the router

3. IP is not in the same network segment

4. The virtual machine service is not turned on

Solution:

1. Open the virtual machine — > Virtual machine settings — > Network adapter — > Network connection, set to bridge mode

2. Open ifcfg eno16777736 under etc/sysconfig/network scripts (the file name may be different), and set:

TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no

HWADDR=00:0C:29:12:7C:E7
PEERDNS=yes
PEERROUTES=yes
IPV6_PEERDNS=yes

nameserver 192.168.0.1                [loacal IP]

3.2 if WiFi is connected, set:

# this is google DNS

# localhost DNS
nameserver 168.192.1.1            [local default gateway]
nameserver 168.192.1.101 [local IPv4 address]
