  • CentOs 设置静态IP

    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
