为Linux服务器设置静态IP的方法

当前CentOS版本号:

[root@localhost ~]# uname -a

Linux localhost.localdomain 3.10.0-862.el7.x86_64 #1 SMP Fri Apr 20 16:44:24 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

更改前的网卡设置：

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=dhcp

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=ens33

UUID=d2db396f-602b-4bce-87d1-b281fd41eec9

DEVICE=ens33

ONBOOT=yes

更改后的网上设置，红色为更改选项：

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=static

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=ens33

UUID=d2db396f-602b-4bce-87d1-b281fd41eec9

DEVICE=ens33

ONBOOT=yes

BROADCAST=192.168.32.255

IPADDR=192.168.32.151

NETMASK=255.255.255.0

GATEWAY=192.168.32.2

保存后重启网络配置，固定IP设置生效。     

[root@localhost ~]# systemctl restart network
