1.修改网卡配置 编辑:vi /etc/sysconfig/network-scripts/ifcfg-eno49

  通过ifconfig命令,查看在用的网卡(特别是网卡别名)。也可以进入/etc/sysconfig/network-scripts目录,然后ls -a列出当前目录清单,找到对应的网卡配置文件

[root@localhost ~]# ifconfig
eno49: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.25.127  netmask 255.255.255.0  broadcast 192.168.25.255
        inet6 fe80::5aaf:8e77:99c5:b91b  prefixlen 64  scopeid 0x20<link>
        ether XX:XX:XX:XX:XX:XX  txqueuelen 1000  (Ethernet)
        RX packets 21072  bytes 2744576 (2.6 MiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 28835  bytes 30976082 (29.5 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
        device interrupt 16  

  在打开的文件中,修改IPADDR、GATEWAY和DNS1等配置项。

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="none"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="eno49"
UUID="b6a8a293-XXXX-XXXX-XXXX-1e4db2096a9e"
DEVICE="eno49"
ONBOOT="yes"
IPADDR="192.168.25.127"
PREFIX="24"
GATEWAY="192.168.25.254"   
DNS1="XXX.XXX.XXX.XXX" 
IPV6_PRIVACY="no"

  

2.修改网关配置 编辑:vi /etc/sysconfig/network

[root@localhost ~]# cd /etc/sysconfig
[root@localhost sysconfig]# ls -a
.           cbq       crond            init              kdump    netconsole       rdisc          run-parts  sysstat.ioconf
..          chronyd   ebtables-config  ip6tables-config  kernel   network          readonly-root  selinux    wpa_supplicant
anaconda    console   firewalld        iptables-config   man-db   network-scripts  rsyncd         sshd
authconfig  cpupower  grub             irqbalance        modules  ntpdate          rsyslog        sysstat

  

3.修改DNS 配置  编辑:vi /etc/resolv.conf

 

4.重启网络服务 执行命令:service network restart  或   /etc/init.d/network restart
